Overview
1.1.
General
Cooling Unit Cooler
The Cooler is a complete one-piece cooling unit for comfort
cooling in air handling systems. All the refrigeration and
electrical components are interconnected and housed in one
common casing. The units are test run prior to delivery.
The coils are designed for installation in the ducting. The
arrangement of piping between the cooling unit and the
coils and the electrical wiring of the cooling unit is carried
out at the building site.
The Cooler can be used together with an air handling unit.
The capacities of the six sizes are however matched to the
size 08-60 GOLD air handling system and the size 004-014
Basic air handling units.
Complete indirect system (sizes 24, 34, 48 and 60)
The size 24-60 Coolers have a complete indirect system.
Heat/cooling energy is transferred across a heat exchanger from the refrigerant to the circulating water mixed with
glycol. Both the brine circuit and the cooling agent circuit
must be filled with a mixture of water and 30% ethylene
glycol after the unit has been installed.
Compressors
Sizes 14, 18, 24 and 34 each have two-piston compressors. Sizes 48 and 60 each have two compressors as well,
but they are of Scroll-type.
Partially indirect system (sizes 14 and 18)
The size 14 and 18 Coolers have a partially indirect system.
On the warm side, a coil (condenser) is used for directevaporating refrigerant, while on the cold side, there is a
heat exchanger, where energy is transferred to the water
mixed with glycol (brine) circulated to the cooling coil in
the supply air duct. The circuits must be filled with a mixture of water and 30% ethylene glycol after the unit has
been installed.
The condenser coil is integrated into the cooling unit fitted
in the exhaust air duct.
Fig. 2
Refrigerant
Cooler has double refrigerant circuits which are separate from one another. The refrigerants used are of type
R407C and R134A in each circuit respectively, each with
its own compressor. On delivery, the refrigerant circuits
are charged. These refrigerants do not have any known
impact on the ozone layer and there are no known restrictions for their use at this present time.
Refrigerant volume
See section 14. General Technical Data.
Reporting obligation
The user is required to submit periodic reports to the local
inspectorate only if the total charge volume exceeds 10
kg.
Annual inspections
Annual inspections by an accredited inspectorate are
required if the volume of refrigerant in the one-piece unit
exceeds 3 kg. This is applicable to the size 24, 34, 48 and
60 Coolers only.

Operation
There are two refrigerant circuits in the cooling unit The
circuits are separate from one another and each contains a
different type of refrigerant.
Each circuit is equipped with its own heat exchanger on
the cold side. On the warm side, both circuits are arranged
through a condenser coil.
The brine (water/ethylene glycol) passes the heat exchanger of both refrigerant circuits.
The refrigerant in gas form is compressed by each compressor and then passes to the condenser coil, where it is
chilled by the air flowing through the coil, and condenses
to liquid form.
A reduction in pressure occurs in expansion valve EV. From
the expansion valve the refrigerant advances to evaporator VVX where the refrigerant vaporises and absorbs heat
from the adjacent medium, i.e. the brine. This chills the
brine. Gas leaves the evaporator and flows back to the
compressor.
Water pump G1 pumps the brine (water/ethylene glycol)
in a circuit from evaporators VVX1 and VVX2, where it is
chilled by the refrigerant and advances to the cooling coil,
which in turn cools the supply air flowing to the air handling unit. The refrigerants are never in physical contact
with the brine. Heat and cooling energy are transferred
across the heat exchangers in the evaporator and condenser.
Control
In a response to an ON/OFF control signal, the controller
switches in pump G1 and compressor M1. The cooling
capacity is controlled by switching in one or two compressors. On increasing cooling load, the controller switches in
compressor M2 and at the same time switches out compressor M1. If even more cooling is required, compressor
M1 is switched in to operate together with compressor
M2.
If the temperature of the outgoing brine becomes too
low, one of the compressors is switched out. When this
condition subsides, it is restarted automatically. Should the
pressure become too low, the low pressure switch will trip.
The equivalent will occur on the warm side. If the temperature of the exhaust air becomes too high, one of the
compressors is switched out. If the pressure still rises, the
high pressure switch will trip.
Specifications are subject to alteration without notice.

Operation
There are two refrigerant circuits in the cooling unit. The
circuits are separate from one another and each contains a
different type of refrigerant.
Each circuit is equipped with its own set of heat exchangers on the warm and cold side respectively. The cooling
agent and the brine (water/ethylene glycol) both pass
through the heat exchanger of both refrigerant circuits.
The refrigerant in gas form is compressed by each compressor and then advances to condenser VVX1 or VVX2,
where it is chilled by the cooling agent (water/ethylene
glycol) and condenses to liquid form.
A reduction in pressure occurs in expansion valve EV and
the pressure drops. From the expansion valve the refrigerant advances to evaporator VVX3 or VVX4 where the
refrigerant vaporises, boils, and absorbs heat from the
adjacent medium, i.e. the brine (water/ethylene glycol).
Gas leaves the evaporator and flows back to the cooling
compressor.
Water pump G1 pumps the brine (water/ethylene glycol)
in one circuit from condensers VVX3 and VVX4 where the
brine is chilled by the refrigerant and then proceeds to
the cooling coil, where it in turn cools the supply air discharged from the air handling unit.
Water pump G pumps brine (water and ethylene glycol)
in the circuit from condensers VVX1 and VVX2, where the
brine cools the refrigerant and further to the brine cooler
(the coil in the exhaust air duct). The brine is cooled there
where it transfers heat to the exhaust air leaving the air
handling unit. After that the brine returns to the condenser.
If the cooling agent isn’t chilled adequately, the COOLER
will temporarily lower its capacity to avoid a shutdown
(shuts off one refrigerant circuit and compressor). The
cooling unit will however revert to operating at full capacity again as soon as the operating conditions so permit.
Control
In response to an ON/OFF control signal, the controller
switches in pumps G1 and G2 and compressor M1. The
cooling capacity is controlled by switching in one or both
compressors. On increasing cooling load the controller
switches in compressor M2 and at the same time
switches out compressor M1. If still more cooling is required compressor M1 is switched in to operate together
with M2.
If the temperature of the outgoing brine becomes too
low, one of the compressors is switched out. When the
condition subsides, it is restarted automatically. Should the
pressure become too low, the low pressure switch will trip.
The equivalent will occur on the warm side. If the temperature of the exhaust air becomes too high, one of the
compressors is switched out. If the pressure still rises, the
high pressure switch will trip.

Other electrical connections
4.2.1GOLD, Version B
General
The Cooler is supplied with two alternative accessories for
controlling the cooling load.
Extra interference protection is required for the Cooler
variants operating where the cooling load is controlled by
an external 0 –10 V DC signal.
To meet the provisions stipulated in the EMC Directive,
concerning insensitivity to interference, the analogue
inputs must be protected by a Ferrit block, 019 210.
Communication cable 019 007 is the accessory, that must
be used when the Cooler operates together with the
Version B GOLD ventilation unit. See the individual instructions.
Design
The ferrit block, 019 210, is designed for snapping
around wires.
The block consists of two ferrit-halves, enclosed in a
plastic casing that can be opened.
The plastic casing has ”hinges” and a simple lock that make
it easy to open and close around relevant wires.
Dimensions: H = 15 mm, W = 15 mm, L = 29 mm and
diameter of the openings = 6.6 mm.
Communication cable 019 007 is a 5 m long flat cable,
with a type RJ 1 modular connection fitted at both ends.
The cable transfers normal communication signals between the control unit and the GOLD unit (Version B), but
not 4 V DC. Both types of control have their own 4 V DC
supply.
Important: Do not use an ordinary bus cable! If the 4 V DC
connections are interconnected, this will cause malfunctions.
Specifications are subject to alteration without notice.
GB.COOLER.INST.060501
Connection of the control and regulation cable to
the air handling unit.
Only one communication cable is required for transmitting
information between the Cooler and the GOLD control
systems. All the operating conditions and alarms are
transmitted across this cable.
Communication: Communication between the Cooler
and the GOLD unit takes place by means of a special
communication cable (PM part number 019 007).
Installation in the GOLD:
Connect communication cable 019 007 to any of the
ABC Bus outlets on the control unit. For the Gold (Version B) see Fig.11!

Instructions for the Cooler with 0-10 V Controller
General
The Cooler is supplied with two optional accessories for
controlling the cooling load. Extra interference protection
is required for the Cooler variants for which the cooling
load is controlled by an external 0 –10 V DC signal.
To comply with the provisions of the EMC Directive that
deals with insensitivity to interference, analogue inputs
must be protected by a Ferrite block, 019 10.
Communication cable 019 007 is the accessory that must
be used if the Cooler operates together with the GOLD
ventilation unit, Version B. See individual instructions on
this topic.
Design
Ferrite block, 019 10 is designed to snap on around cables. The block consists of two ferrite halves that rest in a
plastic casing that can be opened. The plastic casing has
”hinges” and a simple lock that simplifies opening and
closing it around relevant conductors.
Dimensions: H= 15 mm, W= 15 mm, L= 9 mm and diameter of openings = 6.6 mm
Installation
After installing the relevant cables for operating and controlling the Cooler, fit the ferrite block.
Fit the ferrite block around the conductors connected to
terminals 47 – 48 (0-10 V control signal) and the conductors on terminals 43 – 44 (steady 10V output signal), if
used.
Position the ferrite block as near as possible to terminals
47 – 48.

Instructions for the Cooler
Connection of the cooling coil and the cooling agent
cooler to cooling unit
General
6.1
The Cooler is supplied with two optional accessories for controlling the cooling load.
Communication cable 019 007 is the accessory that must be
used if the Cooler operates together with the GOLD ventilation
unit, Version B. See individual instructions on this topic.
Extra interference protection is required for the Cooler variants
for which the cooling load is controlled by an external 0 –10 V
DC signal. In these cases, the ”Ferrite block” accessory should be
used. See individual instructions.
The cooling coil shall be located in the supply air ductwork.
Sizes 14 and 18: Install the refrigerating machine in the
exhaust air ductwork down-stream of the fan. Sizes 24,
34, 48 and 60: install the cooling agent cooler in the
exhaust air ductwork. The cooling unit is designed to
stand alone in the fan room.
Design
Communication cable 019 007 is a 5 m long flat cable, with a
type RJ 1 modular connection fitted at both ends.
The cable transfers normal communication signals between the
control unit and the GOLD unit (Version B), but not 4 V DC. Both
types of control have their own 4 V DC supply.
If an ordinary bus cable is used, the 4 V DC connections will be
interconnected and this will cause malfunctions.
Installation
Connect communication cable 019 007 to any of the ABC Bus
outlets on the control unit.
Use one of the holes in the oval rubber-covered cable glands on
the backside of the electrical cubicle’s junction hood, for running
the cable in to the control unit.
Move a part of the cable gland to the side to insert the Modular
connection through it. Connect the cable to a bus connection
on the control unit. Adjust the cable length inside the electrical
cubicle and adjust the cable in the cable gland. Refit the cable
gland in its correct position.
Lay the communication cable in a safe manner from the plastic
hood on the top panel of the GOLD unit.
Insert and connect the cable correspondingly in the Gold control
unit.
Commissioning
Set the Dip switches on the control unit in the Cooler for communication with the GOLD.
Set Dip switches SW1, 1– 4 = On (up). The Cooler controller will
then operate as a ”slave”.
On delivery, Dip switch SW1, 1 = Off and 2 – 4 = On. The Cooler
controller is then a “master”.
Use the hand-held terminal to set the cooling unit function to
the auto operation mode.
Do this under SETTINGS. See the Operation and Maintenance
Instructions for the GOLD.

6.2
Cooling Connections
Location
Condensate from cooling coil
The cooling coil is equipped with a drip tray with drain
connection (to collect condensate from the coil). A drain
pipe should be arranged from the condensate drain connection to a floor gulley. Size 14 units with the size 08
Gold unit: use the connection on the outlet air side and
plug the connection by the inlet air.
6.3
Liquid connections
Liquid is conveyed by means of pipework. The coils have
female-threaded connections and the Cooler has smooth
connections for brazing or compression ring fittings. The
liquid circuits should be connected in a counter-flow mode
to enable maximal cooling capacity. Shut-off valves should
be installed in the pipework leading to and from the cooling coil to avoid having to drain the whole system of fluid
if work is necessary (such as having to replace a circulation
pump).
6.4
Venting nipples
Fit venting nipples at the highest point of the connecting pipework at both the outlet and inlet of the cooling
coil and the cooling agent cooler respectively. Locate the
nipples where the water is on its way downstream.
See illustrations in Section 3.3.
6.5
Insulating the brine circuit
Insulate the brine circuit of the cooling coil in compliance
with local standards.
6.6
Connection to cooling unit
Connect the cooling coil and the cooling agent cooler to
cooling unit as illustrated in Section 3.3.
6.7
Safety drain
Safety valves for relieving the water circuits are fitted to
the expansion vessels. The safety valves open if the pressure in the system is too high, i.e. they open if the pressure
reaches 1.5 bar.
The drain pipe from the safety valve should be extended to
a receptacle; not directly to a floor gulley since the liquid
circuit contains glycol.
One (sizes 14-18) or two hoses (sizes 4-60),13 mm i.d., is/
are run from the safety valves and out through the casing
to be fitted with an extension to a collecting tank, see Fig.
7 and 8.

Filling with water/glycol mixture
Caution!
The ethylene glycol used is toxic and must never be
consumed!
Accessories used
• Mixing vessel.
• Filling pump for pipes and coils.
5.8.1 Filling
For particulars of the volume to be filled, see information
for the relevant size in the charts in Section 11.
• Blend water/glycol (with 30% admixture of glycol)
into an appropriate mixing vessel and stir.
• Connect the filling hose to the tap in the unit.
Important!
The system must be vented, see Section 6.8.2.
It is essential to evacuate all the air out of the system. It is
advisable to run the pumps with connection to an open
vessel and to alternately vent the unit and hoses, and fill
up. See fig. 15.2.
6.8.2 Venting the system
Vent the system as follows:
• Set the safety switch of the cooling unit in the ON
position.

The venting holes shouldn’t be completely open, but
only slightly to allow the air to be forced out.
To remove all the air from the cooling unit, start the
pumps to transport any air remaining in the circuit to
the venting nipple. Always check that there is
positive pressure in the system (check the
manometer), otherwise the air cannot be forced out.
If the pressure isn’t positive, fill up with more of the
water/glycol mixture.
The system should maintain a positive pressure of
about 0.5 bar while you are venting it.
If there is still air in the system, repeat the venting
procedure as many times as necessary until there is
no air left in the system.
When the system reaches the correct pressure,
close the tap and take away the filling pump.

Maintenance
Clean the inside of the unit whenever necessary.
Carry out a visual inspection at least twice a year.
11.1
•
•
•
•
Cleaning
Stop the Cooler by shutting down the air handling unit or
by setting the cooling unit to ”0” in the cooling menu
image in the air handling unit terminal (i.e. alternate
the ON/OFF signal).
Then shut off the safety isolating switch of the GOLD
Cooler.
Open the inspection door.
Vacuum clean the space and wipe with a damp cloth.
11.2
To change the water/glycol mixture
The need for filling or changing the liquid arises only if
leakage is detected, or if you fear that the water doesn’t
contain enough glycol.
To fill the circuit, follow the directions in Section 5.8.
The correct mixture is 30% ethylene glycol, 70% water.
Do not forget to vent the system!
11.3
Handling refrigerant
Type R 407C and R134A refrigerant is used in the Cooler.
The refrigerant circuit has been charged at the factory.
Caution!
11.4
Charging with refrigerant
Type R 407C and R134A refrigerant is used
If a low pressure alarm is initiated, this have been caused
by too low a volume of refrigerant.
Caution!
Always wear protective goggles and protective gloves
when working with refrigerant. Contact with skin and
eyes may cause frostbite.
Caution!
If the refrigerant is exposed to fire or is intensely heated
in some other way, toxic gases will form.
Important!
Charging with refrigerant must be carried out according
to the refrigerant manufacturer’s recommendations.
Whenever possible, employ working methods that prevent refrigerant contact directly with skin.
Arrange adequate ventilation/local extraction.
Wear tight-fitting protective goggles, protective gloves
and an overall.
Under no circumstances shall unauthorized personnel
be permitted to open the refrigerant circuit. The circuit
contains gas under high pressure. The refrigerant circuit
may only be modified or repaired by qualified personnel
from an accredited refrigeration company.
If refrigerant comes in contact with eyes
Use an eye douche to flush the eyes (alternatively with
lukewarm water) for 20 minutes. Seek a doctor.
Important!
If refrigerant causes frostbite
Seek a doctor.
If you detect any refrigerant leakage, get in touch with
your nearest Swegon Service representative.
Specifications are subject to alteration without notice.
If refrigerant comes in contact with skin
Carefully wash with soap and lukewarm water.

GB.COOLER.INST.060501
11.5
Annual inspection
Annual inspection by an accredited inspectorate is required if refrigerant volume in a one-piece unit exceeds 3
kg per circuit.
This is thus not required the for size 14 and 18 units, but
on the other hand it is for the size 24, 34, 48 and 60 units.
Obligation to file reports
Obligation to report to a local supervisory authority is only
required if the total volume of refrigerant in the company
exceeds 10 kg.
11.6
Service
Only service personnel trained by Swegon shall be permitted to do any work on the cooling unit.
If any repair work is needed, get in touch with your nearest Swegon service representative, see the backside of
these user instructions.

Cooling Coil and Cooling Agent Cooler
Cooling coil and cooling agent cooler are sized to match
the size 08-60 Gold and the size 004-014 Basic units.
The coils consist of copper tubes and profiled aluminium
fins. The casing is made of hot galvanized sheet steel. The
headers are made of steel.
12.1
Instructions for the BASIC unit
Installation
The coil must be vented before the system is commissioned, thus a venting valve should be fitted to the venting
nipple.
The BCKO Cooling agent cooler should be connected for
cross-flow mode as indicated by the arrows on the connection branches. If a shunt unit is fitted, make sure that it
is installed so as not to block inspection of the other functional sections.
Care
Check whether cleaning is required at least twice a year.
The unit should be cleaned in the following way only:
Blow with compressed air towards the ordinary direction
of airflow and then vacuum clean the side facing the ordinary direction of airflow using a soft nozzle.
Wet cleaning can be carried out by flushing with water.
If a solvent is used, it must be of a quality that doesn’t
corrode aluminium or copper. Cover adjacent functional
sections to protect them before you begin cleaning. After
you’ve finished cleaning, blow the surfaces with compressed air to remove all traces of detergent. Swegon
detergent, sold by Swegon Service is recommended.
While cleaning, check for trapped air in circuits, the glycol
content and density, if necessary.

Installation
The coil must be purged of air before it is commissioned,
because a venting valve must be fitted on the venting
nipple.
The BCKA is designed for horizontal airflow, the cooling
section should be mounted with the circuit pipes horizontal to access for venting and draining.
Brine connection (Water)
The BCKA should be installed in accordance with the
airflow direction arrows on the inspection side. The piping should be connected for counter-flow circulation as
indicated by the arrows on the connection pipes. Parallel
circulation is wrong and will lead to a substantial reduction
in capacity.
Keep in mind that the connection pipes must not be in the
way and hamper inspection in other unit sections.
Height A (the distance between the runoff level in the
unit section and the run-off level in the water trap) must
be at least just as large in mm as the negative pressure in
the unit is in mm gauge.
Height B (the distance between the runoff level in the
water trap and the uppermost point in the bend of the Upipe) must be at least just as large in mm as half the negative pressure is in mm gauge.
A set of connection parts that fit the condensate connection are also included when a water trap is ordered from
Swegon.

Pipe connections
Make sure that the deadweight and/or expansion forces of
the piping system will not be applied to the connections.
Use appropriate sealant for sealing the thread of the coil
connections.
Installing the water trap
The water trap must be filled with water before the unit is
started up. The drain pipe should discharge in such a way
that the adjacent unit sections and the building structure
won’t sustain damage. The drain pipe must be insulated
against the cold if it is run through a cold space. A heating
cable may be required.
If the coil is fitted on the suction side of the fan, it is especially important to fit a water trap.

°C. These data presuppose cooling energy recovery by means of a rotary
heat exchanger which then provides an outdoor temperature of 32 °C,
40% RH and an extract air temperature of 26 °C.

See Fig. 23 - 25 and the table below.
16.1 Design
The refrigerating machine is incorporated into a casing
consisting of a framework of torsion resistant profiled
sections made of form rolled 1 mm thick aluminiumzinc plated sheet steel, Env. Class C4. The wall, top and
bottom panels are made of aluminium-zinc plated sheet
steel, Env. Class C4. They are constructed according to
the sandwich principle: 0.7 mm thick sheet steel + 50 mm
thick insulation + 0.7 mm thick sheet steel.
The size 14 and 18 Coolers are to be connected to the
exhaust air connection of the air handling unit by means
of slip clamps. The larger units stand alone and alongside
the air handling unit.
