REASON FOR PRODUCING THIS MANUAL
In 2011, the New Zealand Alpine Club (the Club) completed a major upgrade to its flagship
lodge, Unwin Lodge, situated on SH 80 in Aoraki/Mt Cook National Park.
The new complex now contains modern electrical, plumbing, drainage and ventilation
services which require regular maintenance and /or repair by both incumbent Managers
and trades people called in to carry out specialist work.
This document sets out to describe each system, how it operates, the equipment used, the
required frequency and instructions to maintain the equipment and lists several of the
equipment manufacturers details should spare parts ever be needed.
In addition to new plant, this document includes some of the existing items thus providing a
complete building owner’s manual current at the time of production.
It is the responsibility of the Manager to ensure this document is kept up to date by
recording any changes.
It also details the names and contact details of project personnel in the event technical
assistance is required.
HOW TO USE THIS MANUAL
The manual is divided into easy to follow sections, detailing each service, operation of
equipment, catalogue numbers of equipment, maintenance of equipment; manufacturers
contact details and compliance documentation. It includes all “as built” construction and
services drawings. Several photographs are included to assist identification of some
equipment.
All pages are numbered (with the exception of the “manufacturer’s literature” and “building
compliance documentation” sections) and an index follows this page to assist the reader to
identify the service he/she wishes to research.

SYSTEMS OVERVIEW
COLD WATER SERVICES
Sawyer Stream, observed some several hundred meters up from the rear of the Lodge is the
cold water source for this complex.
A fabricated steel pipe inlet is positioned in the stream flow. Attached to it is a 40NB HDPE
pipe which winds its way down on the ground surface to the first of two black polythene
tanks. Both of them act as gravel and sand filters before a pipe leads to a 30,000 litre
polythene storage tank.
Some distance down from the storage tank a pipe from another water source high in the
bush branches into the main line. This has the intended function of supplying an alternative
flow if the main intake structure is taken out of the Sawyer Stream for any reason. This not
always a successful alternative water supply.
From the main storage tank, a 40NB pipe is laid underground at an undetermined depth to
the boundary fence of the Lodge grounds. Occasional waretah’s mark the route.
Inside the boundary fence continuing underground at a depth of 700 mm as shown on the
“as built” drawings, the 40NB pipe continues to a valve chamber located adjacent to the
Lodge. The chamber contains a valve, filter and water meter. The 40NB pipe then enters the
building in the corner of the Laundry.
Also in the chamber, a 20NB valved branch connection is provided to supply cold water to
the Manager House.
Passing through a set of in line filters and valves in the Laundry, various branches are taken
to hot water heaters and reticulated throughout the building in trace heated and insulated
copper pipes to various plumbing fixtures.
Direct head pressure of 3 bar from the main storage tank is utilized throughout the building
except where in the kitchen a pressure reducing valve lowers it to slightly under 3kpa before
supplying the hot water cylinder.
The cold water services installation complies with NZ Building Code Section G12.

HOT WATER SERVICES
Hot water generation for the ablution block is provided from 4no instantaneous gas water
heaters located in the laundry. The principal operation of these is that when water flows
through a heater(s) electronic circuitry detects a flow and ignites a gas burner to heat the
water. The system is fully automatic and senses water flow rates to variously bring on or
drop off operation of any one or more heater.
Water is reticulated throughout the building in trace heated and insulated copper pipe to
various plumbing fittings.
Water temperature is set to 55 degs C.
Hot water for the kitchen is supplied from a small under bench electrically operated hot
water cylinder.
A water boiling unit is also available in the kitchen.
The hot water services installation complies with NZ Building Code Section G12.
PLUMBING INSTALLATION
Ablution facilities are available in the form of two main toilet and shower areas for male and
female use. In addition there is a single shower room, a single toilet, and a disability
shower/toilet for general use.
Showers are controlled from thermostatic mixers through swivel shower heads. Hot and
cold water is provided to basins and sinks through separate taps.
The plumbing installation complies with NZ Building Code Section G13.
DRAINAGE INSTALLATION
The drainage installation has been installed in accordance with AS/NZS 3500.2.2. All foul
drains are under the building slab or underground with waste pipes from the various
sanitary fittings dropping to the drains in wall linings. A single lateral drain runs under the
slab to a septic tank located in front of the building.
A single terminal vent rises to the apex of the kitchen roof. Several drain rodding points are
installed.
Drainage services are detailed on “as built” drawing 06

IN GROUND SEWAGE SYSTEM
Located in front of the deck is a 10,000 litre septic tank. From this tank pipework connects it
to another 10,000 litre settling tank and finally to a 5,000 litre pump chamber tank.
The internal submersible float operated pump discharges foul water through a 63NB HDPE
pipe to a 4 outlet sequencing valve and 4 buried laterals in the dispersal field which is
located to the NW of the main building. Details of the installation are shown on “as built”
drawing “on-site drawing sheet 1”
Also fixed to the North of the outside deck is the electrical control panel for the pump
control function of this installation. A red light sits atop this panel and flashes in the event of
a pump failure.
An emergency overflow from the pump chamber discharges through the front landscaping
bank.
The drainage installation has been installed in accordance with AS/NZS 3500.2.2.
EXTRACT VENTILATION
There are three toilet extract ventilation systems and an extract fan located in a canopy over
the kitchen ovens.
There is one system for each of the male and female ablution areas and one system for the
remaining three smaller ablution rooms.
In line fans are located in the ceiling space above the ablution areas with flexible metal
circular ducting connecting the fans to ceiling mounted extract louvres. A grille is located in
each door to allow extracted air to be replaced in each space.
All three fans are wired through light switches and timers set to give a “run on” after the
light switches are turned to “off’. Likewise the fans are not activated until a light is turned
“on”. The fan for the three small ablution rooms will start if the light in any room is switched
“on”.
Discharge grilles are located under the soffit externally to the ablution area.
Extraction of air above the kitchen ovens is achieved with a wall mounted propeller fan
controlled either “on” or “off” by a switch located adjacent to the ovens.
Ventilation to the ablution areas has been installed in accordance with NZ Building Code G4,
New Zealand Alpine Club Inc.

Page 11
A small wall mounted extract fan is located in the Drying room in the shed.
Three ceiling mounted propeller fans are located in the day room with the intention of
providing a down flow of either hot or cool air depending on the season. They are switched
from the wall adjacent to the door at the front of the room.
ELECTRICAL SERVICES
Reticulated power is provided throughout the Lodge. An underground mains cable from the
adjacent Alpine Energy substation enters the building at the corner of the Laundry and feeds
through to a main distribution board (DB) located in the Foyer. All power outlets, lights,
heater controls, metering and circuit breakers are contained in this DB
A set of “as installed” electrical circuitry drawings are located on the inside of the DB door.
A separate circuit for the Managers house originates from this DB
The electrical installation complies with NZ Building Code G9
ONLY SUITABLY QUALIFIED PERSONS SHOULD ATTEMPT ELECTRICAL REPAIRS
FIRE ALARM SYSTEM AND EXTINGUISHERS
Throughout the complex except the Managers house, a fire and smoke detection system is
installed complying with NZ Building Code Type 5, to NZS 4512:2010 and AS/NZS 2220.
The system is complete with smoke detectors, heat detectors, alerting devices, manual call
points, and a panel located in the foyer accessible to be viewed by an attending fire brigade
team in the event of a fire.
Illuminated exit signs are located throughout the building, and in the event of a power
failure an uninterruptable power supply (UPS) will keep the signs illuminated for a short
time.
Several fire extinguishers are located throughout the complex.
THE FIRE ALARM SYSTEM IS NOT CONNECTED TO EMERGENCY SERVICES.

GAS RETICULATION
The only items of equipment utilizing a piped gas supply are the 4no instantaneous hot
water heaters located in the laundry.
Adjacent to the shed across from the Manager house, a lockable gas bottle cage houses 4no
cylinders. At the rear of the bottles a gas train consisting of valves, regulators and
changeover switches is bolted to the wall.
A 25NB polythene medium pressure gas supply runs underground to a location external of
the kitchen. It rises from the ground and into a wall mounted steel cabinet containing a
pressure regulator before entering the building to the laundry where the hot water heaters
are located. A header pipe below the heaters contains isolation valves to each of the
heaters.
MANAGER’S HOUSE PLUMBING SYSTEM
A valved cold water supply enters the building via an in ground timber covered chamber
located at the front of the house. This chamber also contains the system drain valves and
the overflow from the header tank in the roof space. Hot water is generated via a 180 litre
hot water cylinder with an electric element and thermostat.
There is a continuous cold water flow through the roof space header tank to prevent
freezing in the winter and a ball float valve in the tank for summer use.
Foul drains are directed to the managers house dedicated septic tank located to the side of
the Managers house external to the boundary fence.
The house plumbing and sanitary fittings are common to similar dwellings of the age of the
house.

SYSTEMS OPERATION
COLD WATER SERVICES
Management of the cold water supply to Unwin Lodge is critical to its operation.
Intake structure and pipe to tanks
The intake structure in Sawyer Stream (Refer Photo section) must be completely submerged
and the draw off pipe leading from it should descend from it without a rise.
A chain fixed to a bolt anchor on a rock secures the intake pipe structure.
It is necessary to make frequent visits to the site to make sure water is continually running
into the 30,000 Litre storage tank. Frequent adjustments to the position of the intake will be
necessary especially in times of low rain fall when the Stream may lower rapidly.
A daily indicator of the tank being full is to observe the overflow pipe from the storage tank.
If it is running continuously the tank is full. If it cannot be seen running then it is not being
filled from the intake.
Several scenarios exist if the tank is not being filled.
The intake structure is out or partially out of the stream flow
There is an air lock in the pipe somewhere.
There is silt/stones in the lower section of the pipe.
Stones have jammed against the valve adjacent to where the alternative water
source joins the main line. Roughly half way between the intake and the first silt trap
tank.
5. A flash rain event has separated the pipe from the intake.

2.
3.
4.
To clear an air lock it is generally adequate to make sure the intake is in the stream flow.
Often shaking the pipe along its upper lengths may also clear it.
To clear a blockage caused by silt/stones it is generally necessary to disconnect the first
joiner down from the intake, where it dips, and shake the pipe into the stream.
Often stones will travel down the pipe and get jammed in a valve located where a secondary
water pipe branches into the main 40NB pipe, some 100 mtrs down from the intake.
To clear this it is necessary to operate the valve “on” and ”off” several times. It is usually
possible to hear the stones clear. Disconnection is the alternative way to clear stones.
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook

Page 14
Essential to the management of the supply is to take note of severe upcoming rain events
which will be forecast by NZ Met Service on their web site.
If a warning of over 100 mm is forecast in a 24 hr. period it is advisable to remove the intake
from the stream flow. Leaving the intake in the flow during high water flow will make it
difficult to extract and often the ferocity of the flow will separate the 40NB pipe from the
intake. In addition stones and silt will often fill the pipe.
AT ALL TIMES GREAT CARE SHOULD BE TAKEN WHEN WORKING AROUND THE INTAKE
STRUCTURE. ROCKS MAY BE SLIPPERY AND WHEN IN FLOOD SAWYER STREAM
EXPERIENCES DRAMATIC HIGH WATER LEVELS. IN THESE CIRCUMSTANCES IT IS
RECOMMENDED THAT TWO PEOPLE CARRY OUT WORK AT THIS LOCATION
The secondary supply line from an unnamed creek serves to trickle feed into the main 40NB
supply pipe. This is however not a reliable source of makeup water and it is suspected that
the intake is frequently out of any stream flow.
The two 300 litre black polythene tanks which act as sand/rock/gravel filters experience
large quantities of deposits in both tanks. Whilst difficult it is advisable to remove as much
of the deposits as possible. Various valves are located adjacent to the tanks for local
isolation.
The 30,000 litre storage tank has an isolating valve on the main supply to the Lodge and a
drain valve (refer Photo section)
As an aid to Managers it is advisable that for normal operations, the valve outlet is set for
‘high position’ draw off to ensure the tank is not unexpectedly drained without warning.
When water stops flowing to the Lodge, then the tank valve can be opened to allow use of
the remaining contents of the tank.
Valve Chamber (adjacent to external kitchen wall of lodge)
A 40NB ball valve is located on the upstream side of a basket filter and water meter.
This will totally isolate the Lodge and Managers house cold and hot water supplies.
It will be necessary to remove the filter housing on occasions to clear any silt etc. It has also
been found that should a major air lock occur in the supply pipe, removal of this
filter/housing and opening the valve fully for several minutes, will assist to clear the air lock
and indeed any gravel or silt remaining in the pipe..
The water meter records the flow in m3 (1000 litres = 1m3) There is no legal requirement at
the time of writing this manual to record water usage and because during winter periods
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook
Building Owner’s Manual
Page 15
when the continuous flow is operating to prevent freezing, then an accurate water usage of
the Lodge is not possible. However for future use recorded flows would be usefull.
An isolating ball valve downstream of the meter can be used if it is necessary to remove the
meter.
A 20NB branch complete with isolating ball valve supplies the Manager House.
Lodge cold water reticulation
The 40NB cold water supply rises through the floor slab in the laundry. A valve (refer Photo
section) will completely isolate the building water services supply.
Two cartridge filters assist in the removal of silt.
First in line cartridge contains a 5 micron Taylor Polypleated pre filter 20BPF/05 followed by
a second cartridge pre filter containing a Taylor string wound 20BST/01.
Recommended filter changes are detailed in ‘Maintenance Schedules’ section of this
manual.
Valves upstream and downstream of the filters are to be closed before changing filter
cartridges.
A plastic ‘ring spanner’ is hung near the filters which is used to unscrew the filter housings.
Excess water will spill to the floor when changing filters.
Care should be taken when screwing the housing back into position that the rubber ‘O’ ring
is correctly located.
After a filter change, turn on both valves and depress the red buttons on the top of the filter
housing to expel air from the housing.
Following the filters, the cold water pipework leads to a header arrangement underneath a
bank of 4no instantaneous hot water heaters. Each branch to the heaters is valved for ease
of isolation and maintenance.
Pipework then rises into the ceiling space where it variously splits to serve sanitary fixtures.
Valves are located where shown on the ‘as built‘ drawing.
A branch cold water pipe leads to the kitchen appliances and electric hot water cylinder.

Continuous Winter bypass
Whilst the internal pipework is heat traced, described later in this section, severe winter
frosts and the uncertain underground depth of the main cold water supply from the 30,000
litre storage tank, make it necessary to provide a continuous flow through this section of
pipework. A 15NB valve is located in the Laundry (see photo) which should be turned on at
the outset of winter. It is likely that the valve turned to one quarter open is sufficient to
prevent freezing. The drain pipe from this valve is installed under the floor slab discharging
at the front of the building. A situation can arise that, if a rain event necessitates removal of
the intake structure, AND the continuous anti-freeze valve is opened to drain, that over a
period of time the 30,000 litre storage tank could empty. (Similarly the cold water supply
tank for the Managers hot water cylinder) On the spot management and decision making in
this scenario is required.
Summer conditions do not need continuous flow of either the Lodge or Managers house
cold water supply. Refer to photo section for instructions to switch from summer to winter
use.
Heat traced pipework
The total length of hot and cold water pipework in the new building is insulated with 19mm
thick Armaflex FR Armacell pipe insulation. This encases a heat trace cable to prevent
freezing.
There are two separate trace heating systems, one for the bathrooms and one for the
kitchen area.
The kitchen trace heating is controlled by a single “on-off” switch located under a bench
adjacent to the hot water cylinder.
The heat trace product installed is Thermon FLX self-regulating winterization/freeze
protection cable complete with an external Thermon TC ambient sensing thermostat. This is
located immediately above the main rear entrance to the Lodge and is set to activate at 0
degs C.
A further pipeline thermostat is located in the ceiling space to prevent the temperature of
the heat traced water exceeding 10 deg. C.
The trace heating to the bathroom pipes is controlled by an “on/off/auto” switch located in
the main switchboard located in the Foyer. This switch also controls the bathrooms’ wall
mounted convector panel heaters.
When the bathroom trace heating circuit is operational and power is being supplied to the
bathroom trace heating system, an indication light on the wall of the Laundry will light. If
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook
Building Owner’s Manual
Page 17
the thermostat reaches the set point it will turn off the power to the trace heating and also
the light will extinguish. The reverse will occur if the thermostat drops below the set point,
the light and the trace heating will come on.
As the building and pipework in the Lodge are extremely well insulated, it is not essential to
switch the trace heat ‘on’ at the first onset of a frost. Only when predictions are for a
lengthy period of frosty weather should the trace heating be switched ‘on’. It can then be
left on for the duration of the winter, controlled by the thermostat.
This does not apply to the kitchen trace heating. As insulation to the pipework is not
thermally efficient, trace heating should be switched ‘on’ at the first sign of frost and is to
remain ‘on’ basically for the duration of the winter period.
A full technical description of the Thermon trace heating and operational instructions is
located in ‘manufacturer’s literature’ section of this manual.
Pipework and Valves
Underground external pipework material is MDPE.
Pipework in the Laundry is Fusiotherm PP-R by Aquatherm with valves type Fusiotherm PP
Pipework throughout the Lodge is copper pipe to NZS 3501.
Valves on copper pipe are Haitima fig 2006.
External hose tap
During summer months an external hose tap and hose can be used. During winter months
this hose tap should be isolated from inside the Laundry and the short section of pipework
and valve to outside drained down to prevent freezing.
System drain valve
A valve is located in the Laundry to facilitate complete draining of the hot and cold water
pipework in the Lodge should it be necessary.
Kitchen Cold Water supply
A branch is taken into the kitchen area, insulated and running in the outside wall cavity. It is
heat traced, controlled from a switch located adjacent to the hot water cylinder.
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook
Building Owner’s Manual
Page 18
Managers House
A traditional header tank system for the hot water tank is fed from the 20NB cold water
pipe leading from the Lodge valve chamber. The pipe enters the building through a timber
covered valve chamber adjacent to the manager’s house. An isolating valve is located here.
The supply to the tank has two alternative feeds, one for winter use as a continuous flow; it
is controlled by a hand tap located adjacent to the managers shower taps and marked as
such. There is a constant trickle flow through the tank to prevent winter freezing.
The second feed is through a ball float valve mounted in the tank and should be used for
summer conditions. See photo section.
A drain tap and hose tap is also located in the managers house valve chamber.
HOT WATER SERVICES
Hot Water Generation
Hot water for the ablutions is provided through a bank of 4no instantaneous gas heated hot
water generators.
The units are manufactured by Rinnai Ltd and are model HD200i.
These are a sophisticated electronically intelligent hot water generator.
On no account should work be undertaken on these units unless the operator has
experience working with this equipment.
Full operating and maintenance instructions are included in the ‘manufacturer’s literature’
section of this manual as is the location of skilled personnel in the event of a breakdown.
Hot water has been set to deliver at 55 degs. C.
The hot water generators are dependent on a 240v SP electricity supply. A power outage
will prevent the heaters from operating.
Pipework and valves
Below the 4no heaters is a pipe header arrangement each with an isolating valve on the hot
water flow from the heaters.
Hot water is then reticulated throughout the complex to the various sanitary appliances.
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook
Building Owner’s Manual
Page 19
Pipework is in copper and is also insulated and heat traced as described in the ‘Cold Water
Services’ section of this manual.
It should be noted that due to the distance from the heaters to the furthest tap in the Ladies
ablutions, hot water will take some minutes to reach that point after a long period of nonuse.
Also common to this type of hot water system is that a ‘cold slug’ may be experienced by
users on first using for instance the showers after a brief period of ‘no flow’. This is not a
fault in the system.
Kitchen Hot Water
A 40 Litre electric hot water cylinder provides hot water to kitchen taps.
The temperature has been set to 60 degs. C.
Standard 2kw electric element and thermostat are installed.
Cold water is supplied to the cylinder through a domestic pressure reducing valve, cold
water relief valve and temperature controller.
A drain valve for this system is located on the external side of the wall where the HWC is
located.
A 2.5 litre water boiling Rheem Laser ‘classic’ wall mounted unit is provided. Children
should not be allowed to operate use this heater. Page 11 of the literature details the fault
finding guide.
Manager House Hot Water System
A 180 Litre electric hot water cylinder provides hot water to the kitchen and bathroom.
The temperature has been set to 55 degs. C.
Standard 2kw electric element and thermostat are installed.
A copper ‘header tank’ is located in the roof space for cold water supply to the HWC.
A drain valve located under a timber cover adjacent to the house will drain hot and cold
water pipework should the need arise

PLUMBING INSTALLATION
Sanitary appliances including WC pans, seats, flush boxes, wash hand basins, taps, showers
and shower heads are all as described in the ‘manufacturers literature’ section of this
manual.
No specific operating instructions are necessary for this equipment.
During the first year of the Lodge being in operation, an infrequent occurrence has been
that waste matter deposited in several WC pans, accompanied by a large quantity of toilet
paper, when flushed, has caused the water seal to be ‘pulled’ lowering the trap water
level to beneath the upper bend section of the WC pan trap thus allowing foul odors from
the in ground drain pipe to permeate through the ablutions rooms and adjacent corridor.
This is simply fixed by flushing the WC again to form the usual water seal in the offending
WC pan.
The smell from this event is quite obnoxious for visitors and should be attended to
immediately.
Local isolation and drain valves can be found adjacent to sanitary alliances for maintenance
of ball cock washers, taps etc.
DRAINAGE INSTALLATION
All foul drains for the main ablutions are located under the floor slab. A terminal vent rises
at the rear of the kitchen. Various drain rodding points are located to facilitate insertion of
drain rods should the occasion arise to unblock drains. Their location is as shown on the ‘as
built’ drawings. Kitchen and Laundry drains from sinks and washing machine discharge into
external gulley traps prior to connecting into the main drainage system. No operating
instructions are deemed necessary for this installation.
IN GROUND SEWAGE SYSTEM
Foul drains as described above gravity fall to discharge into 2no 10,000 litre in ground plastic
septic tanks which are piped in series before discharging into a 5,000 litre plastic pump
chamber.
Located in this chamber is a sewerage pump and float switch.
The pump is model Grundfos AP12.40.08.03 3ph 400v. A comprehensive technical brochure
is located in the ‘manufacturer’s literature ‘section of this manual.
New Zealand Alpine Club Inc.
Unwin Lodge, Aoraki/Mt Cook
Building Owner’s Manual
Page 21
The pump is fitted with a suction strainer. In the unlikely event of a blockage the pump will
need to be lifted from the tank.
No maintenance is required for this pump as all bearings are ‘sealed for life”
Controlling the level of liquid in this pump chamber, a float switch is fitted to turn the pump
‘on’ to discharge liquid and ‘off’ when the liquid drops in level.
The float switch is a Contactus 9006 series, model FSW-12532 which requires no
maintenance. The switch has been wired to ‘close on fall’.
Located adjacent to the in ground sewage tanks mounted above ground against the front
deck of the Lodge, is the pump and float control cabinet. It is manufactured by MATelec of
Australia; model FPC-15006 for single pump control. A comprehensive operating manual is
included in the ‘manufacturer’s literature’ section of this manual
A RED FLASHING light mounted on top of the cabinet, when flashing, signifies a malfunction
of the pumped system and immediate attention to the problem should be given. This is
highly likely to be an electrical fault. An electrician should be called in the first instance.
Should a fault occur and the pump is inoperable, an emergency overflow will discharge
liquid waste over the bank between the road and the tanks.
Discharging from the pump and travelling underground in front of the ‘Harper’ bunkroom
and beyond under the grassed area, is a 63mm dia. PVC pumped liquid line. As can be
identified on the ’as built’ drawings, prior to entering the disposal field, the pipe enters a ‘4
port Sequencing Valve’. A green valve cover can be observed covering this automatic valve.
Its function is to alternatively direct liquid sewage into one of the 4no 22metre x 2.4 metre
beds located in the sewage disposal field.
Should this valve need clearing, all Health and Safety procedures should be observed
whilst working with raw sewage.
EXTRACT VENTILATION
Three separate systems are used in the ablution areas.
1. Male toilet/showers. Located in the roof space is a Fantech model TD800/200SIL Lo in line fan. This has a 2 speed motor and is set on ‘high speed’.
The main ablution light switch activates the fan to ‘on’. A ‘run on’ timer is also
installed which allows fans to run for 7 minutes after the main ablution light
switch is turned ‘off’.

ELECTRICAL SERVICES
Alpine Energy Ltd provides the 400/230v supply for Unwin Lodge. The retailer for supply of
power at the time of writing this manual is Contact Energy. A substation located at the rear
and beyond the Lodge boundary, is the source of the 440/230v 3ph Electricity supply. The
connection capacity is 100 amps per phase.
The underground cable route is shown in the ‘as built’ drawings section of this manual.
The main distribution board (DB) for the complex is located in the foyer at the rear of the
desk. This DB houses meters, heater isolation switches and all other switches and RCD’s for
the various circuits throughout the building. The Managers house supply also originates
from this DB.
The wiring diagrams for this DB are located inside a pocket of one of the doors.
For any supply issues contact Alpine Energy Ltd 0800 66 1177. Contact Energy should be
called for retail supply issues and emergencies 0800 80 9000
Lobby, outside and corridor lights are shown on ‘as built’ drawing # E04/A
The above lights are controlled by a three position switch “on’, “auto’, ‘off’. Control whilst in
the ‘auto’ position is via a PIR model RS8B sensor.
Bunkrooms, bathrooms and common room lights are shown on ‘as built’ drawing # E04/B
Bathroom extract ventilation fans are controlled through their light switches with run-on
timers as previously described.
All switched socket outlets (SSO) for the complex are shown on ‘as built’ drawing # E04/C
Pipe trace heating and frost protection circuitry is shown on ‘as built’ drawing # E04/DB.
Trace heating cable is Thermon type FLX rated at 16 watts/metre. The controller is located
externally above the main entrance to the foyer. It is type TC-Ambient by Thermon, set at 0
degs C. A further pipeline thermostat is installed in the roof space which prevents traced
water to exceeding 10 degs C. This is a Honeywell model 675A.
The trace heat cable type for the Kitchen pipework is unknown. It is controlled by an “on –
off” switch located adjacent to the kitchen hot water cylinder.
Located in both male and female and ablutions are wall mounted panel heaters type Skope
Airelec Tactic. The single WC is fitted with an Econo-Heat panel heater model 0603 rated at
400w. The heaters do not function unless the trace heating to pipework is turned ‘on’. They
are provided for frost protection only. Operating instructions are located in the
‘manufacturer’s literature’ section of this manual.

General purpose heating for bathrooms is via high level wall mounted fan heaters, type
Skope 977EA. These are individually switched but also operating through a PDL preset time
Model 648TM. These are mounted adjacent to the rooms light switches. Timers have been
preset for duration of 30 minutes.
All bunkrooms with the exception of Harper, Teichelmann and Thomson, are provided with
wall heaters type Skope Airelec Tactic model ET20 rated at 1800-2000 W. These are
individually switched but also operating through a PDL preset time Model 648TM. These are
mounted adjacent to the rooms light switches. Timers have been preset for duration of 60
minutes. Thermostats can be ‘locked’ at a maximum setting for energy efficiency. Position 7
is suggested. Details of how to achieve this can be found on page 10 of the heater literature.
The Harper bunkroom is heated with a Skope surface mounted wall fan heater model 990E.
This is individually switched but also operates through a PDL preset time Model 648TM.
This is mounted adjacent to the rooms light switch. Timer is preset for duration of 30
minutes.
Teichelmann and Thompson bunkrooms can be heated with transportable electric heaters
at the request of visitor’s requirements.
Both the manager’s house and shed have external security lights installed.
Exit and Emergency lights
The location of these is shown on ‘as built’ drawing # E04/E
Exit and emergency lights are “maintained” and operate all the time.
There is an emergency light “test” switch located in the main DB. This key operated switch
simulates a failure of supply to the lighting circuits, forcing the lights to operate for 60
minutes.
Exit and emergency lights will continue to operate for a short time if there is mains power
outage to the complex. Each unit has a dedicated back up battery to give an uninterruptable
power supply to the lights. Details of the exit signs and emergency Pierlite Luminaires are
located in the ‘manufacturer’s literature section of this manual.

There is a ‘fly catcher’ located in the kitchen. Manager’s discretion is needed to use this or
not.
A Wi-Fi internet station is provided for Lodge users. Zenbu is the provider. Direct all
enquiries to them if assistance is needed. A Nano station is located outside the Managers
house to boost the Wi-Fi signal to the Lodge. Disconnect all telecoms if lightning is present.
A data projector is available for use as per discretion from the Manager. Replacement of the
lamp would be a costly item. Only allow experienced users of this IT equipment to use the
projector,
Fire Alarm System and Extinguishers
Under the directions of NZS 4512:2010, a Type 5 fire alarm system has been installed in
Unwin Lodge.
It comprises a Pertronic analogue addressable fire control panel, (viewable by the Fire
Brigade through a rear Foyer window), a UPS, smoke detectors, thermal detectors, manual
call points, evacuation sounders and silencing push button switches.
The wiring diagram for this element is retained in the fire control panel. This details the
location of all equipment.
Should an alarm be heard, the Lodge should be evacuated by the Manager as per the agreed
evacuation procedure. After evacuation and the cause of the alarm established, subject to
not endangering life, the alarm can be silenced by simply turning to ‘off’ the key which is on
the face of the cabinet.
On occasions insects may well enter a sensor and set off the alarm. The sensor involved will
be identified on the control panel. The specialist company indicated later in this manual
should always be called to rectify faults.
The fire alarm system is complex; non-qualified persons should not attempt to fix any
malfunctions.
THE FIRE ALARM SYSTEM IS NOT CONNECTED TO EMERGENCY SERVICES.
DIAL 111 IN THE EVENT OF A FIRE
In addition to the fire alarm sensors and as an aid to extinguishing fires, several fire
extinguishers are located in the Lodge and Managers House. These are all
Fire extinguishers of Wormald manufacture can be found in the following locations:-

Gas Reticulation
The only appliances to utilize gas are the 4no Hot Water generators.
Located adjacent to the shed, is a locked gas bottle cage, with a rain/snow roof, currently
with 4no 45kg bottles of LPG stored. Capacity of the cage is for 8no bottles.
A pipe manifold behind these bottles consists of automatic changeover valves and isolating
valves.
Underground gas pipework and rising into the building is installed in Rifeng multilayer gas
piping system. Isolating gas valves comply with ASA 6017.
All gas pipe exposed to view is appropriately labeled.
External to the building on the kitchen wall adjacent to the valve chamber, is located a
Jeavons j125 size 25mm over pressure regulator/protection system.
Due to oil contaminants occasionally causing problems an annual inspection should be
made.
If in the rare event, gas supply from the bottle bank runs out, and the water heaters stop
working, it may be necessary to depress the small arm on the governor to evacuate air from
the pipework. This is a simple matter of taking off the governor cover and depressing this
small arm. Air and finally gas will be expelled from the system. Water heaters will
automatically start when a tap is turned ‘on’
