Safety Basics
All agents may be and must
be considered to be
hazardous at concentrations
above their normal design
levels and may be toxic or
create dangerous oxygen
levels, e.g. may be very
dangerous if released into
enclosed room, van or
shipping container.
Safety Basics
Never rush your work!
Safety comes before an early
finish.
Think before you act.
Safety Basics
Before installing any pipework
from the system container(s),
the container(s) must be
secured to an immovable
object.
If this is neglected and the
container accidentally
discharges the container will
become a dangerous projectile!
If this happens there could be a
serious injury or worst still
someone could be killed!
Safety Basics
Do not remove plugs or any
part
whatsoever from a valve
unless you know the
principle of operation.
Never remove plugs from
actuation ports until you are
immediately ready to fit
actuation components.
Do not fit actuators until you
have verified they are in the
reset position.
Safety Basics
Never move a container that is not
fitted with an anti-recoil device.
Never move a container that is not
fitted with a valve protection device
i.e. transportation cap.
The container protection cap protects
the valve during transit and MUST be
left with the customer upon
completion of the installation.
Always use a container trolley to
avoid possibility of a container falling
over or a lifting injury.

Installation
Important!
Installation drawings must be prepared for
the hazard.
Installation drawings contain the following information:
enclosure volumes / agent quantities
container data
scaled pipe network plan + pipe network isometric
pipe diameters, pipe length, drops & rises
nozzle data
solenoid actuator technical data
wiring charts (low pressure switch, pressure
switch, actuator)
fittings data
Installation
Important!
Installation drawings must be prepared for
the hazard.
These drawings should be followed closely
in order to ensure that the system meets its
design criteria.
If for any reason modifications are required
the system must be recalculated before
proceeding with the installation.
Container Installation
General:
Container location is identified on the
system drawings
Containers must be firmly secured to
a wall or bulkhead
Container Installation
General:
No safety outlet and actuation caps
should be removed at this stage!
Single Container Installation
Fix the back channels of the mounting brackets to the
wall at the appropriate hights using suitable anchor
type bolts.
Single Container Installation
The bracket assembly is designed to be mounted to a
rigid surface with the container assembly resting on
the floor.
Each strap is notched for insertion into the back
channel allowing the container to be properly aligned.
Single Container Installation
Position the container against the back
channel with the valve outlet pointing left.
Insert the
container
straps at top
and bottom
and secure
with the bolts
provided.
Single Container Installation
Remove the safety outlet cap from the valve
outlet adapter
With the cap removed
from the valve outlet
adapter, install a union
coupling.
Caution. Do not over
tighten the container
connection. Excessive
tightening may cause the
valve outlet thread to be
damaged.
Remove the union and replace the safety
outlet cap after the initial pipe run has
been installed.
Multiple Container Installation
Fix the back channels of the mounting brackets to the
wall at the appropriate hights using suitable anchor
type bolts.
Multiple Container Installation
Position the containers against the back
channel with the valve outlet pointing left at the
required spacing for the manifold ports.

Pipe Installation
General:
The installation should commence at the union elbow
(single container) / manifold assembly (multiple
containers) and progress along to the discharge
nozzles.
Pipe Installation
Section 5
General:
Install the pipework acc. to the installation drawings
provided ensuring that the following is adhered to:
 The piping material must conform to the
requirements of BS5306: Part 5 Section 5.1.
/ NFPA 2001 2-2.
 The pipe must be reamed, blown clear and
swabbed with an appropriate solvent to
remove mill varnish and cutting oil before
assembly (required by BS / NFPA).
 PTFE tape is the only acceptable pipe
sealant and must be applied to the male
threads.

Pipe Installation
Pressure test of pipe work depends on standard / local
regulation.
• All open ended pipe shall be pneumatically tested in a
closed circuit for a period of 10 minutes at 3 bar.
• At the end of the 10 minute period the pressure drop shall
not exceed 20% of the test pressure i.e. 2.4 bar.
Pipe Installation
Pipe Hangers:
Hangers must be spaced
according to the size of the
pipe.
Hangers must be fixed to a
structure capable of
supporting the pipework.
Pipe Installation
Pipe Hangers:
Hangers must be placed within 300 mm (12") of
the discharge nozzle.
Hangers must be placed between elbows that are
more than 600 mm (24") apart.

Nozzles
All nozzles require the installation of a dirt trap
comprising 1 side tee, 2 nipples and 1 pipe cap.
Fit the nozzle to the nipple of the dirt trap and check
the nozzle orifice to ensure proper orientation.
Nozzles
Nozzles should be installed
a maximum of 300 mm
below the ceiling.
max. 300 mm
A false ceiling comprising loose tiles must have the
tiles retained within a 2 m radius of the nozzle to
prevent moving during discharge.
