4.6 Nozzles
The nozzle consists of a body (1) with a built-in turbulence former and a fixed, sintered filter (2).
Around the body an O-ring (3) is placed. The end of the nozzle has a hole from which the water-
mist is discharged. To prevent the hole from getting clogged up by dirt, dust etc. a protective
hood (4) is included in the delivery. This hood should remain on the nozzle after installation. It
will be forced off by the released pressure when water-mist is created. When assembling the
nozzles you should use a thread-locking liquid or thread-tape. Please note, that it is very
important to make sure that the thread-tape does not come loose and enter into the
piping, since this could obstruct the nozzle filters.

Install the nozzles in "the ceiling" of the protected room.
They should be 70-90 cm apart and 30-45 cm from a wall in
order to obtain the most effective distribution of the flow.
The nozzle will spray the water-mist in a cloud, at an initial
spreading angle of approx. 110°. The spray will bend off at a
point about 20-25 cm from the centre of the discharge. It
will then spread with full force in the form of a pillar with a
diameter of 50-60 cm at a distance of about 100 cm from
the nozzle. The flow from separate nozzles should be
directed so that the mist-clouds do not neutralize each other
("collide"). There should be as few objects as possible in the
way, so that the formation of mist is not affected.
Fire extinction will become more effective if the nozzles are
directed towards spots where a fire might start, for example
the atomiser pipes of a diesel engine or the carburettor of a
petrol engine. Preferably, the mist should hit some hot
components, for example the turbo, since this will speed up
the vaporization and thereby the extinction.

The pipes are installed with clamps (Fig. 9 A och B) and screws. Use one clamp per 30 cm of pipe. We
recommend that you use clamps on both sides of couplings. Use a sufficient number of clamps, so that
the pipes do not vibrate or sag.
IMPORTANT
Blow the pipes clean before installing the nozzles. Any filings and burrs may reduce the diameter
of the pipes and nozzles, resulting in restricted throughflow of extinguishant when Fogmaker
Universal is activated.
4.3 Installing Pipes
When the pipes have been cut to a suitable length and the ends have been cleared as described in section
4.1 you proceed by installing the couplings. The pipe you are going to connect to the release valve must
first be drawn through the wall separating the protected room and the area where the extinguisher will
be installed. To do this you need a bulkhead fitting of nickel-plated brass (Fig. 9 A and B), which is a
standard item in the installation kit. Connect the pipe to the bulkhead fitting. On the outside of the wall
you should now install the valve hose which connects the extinguisher valve to the sprinkler system.
How to connect pipes and couplings:
slip the nut onto the pipe end
slip the inner clamp ring on the pipe end. NOTE: make sure it is in the right direction!
insert the pipe end into the coupling, lubricate the thread and sleeve using copper grease and
pull the nut tight, thereby locking the clamp ring
check that the pipe is properly locked in the coupling
Tighten the nuts, first by hand and then another 3/4
of a turn using a tool.
Install the nozzles using angle couplings (type 2 Fig 9 A) or T-couplings (type 6 Fig 9 B) in combination
with sleeve couplings (type 13 Fig. 9 B). You can also use pipe ends in combination with end couplings
(type 4) where the nozzles can be installed. Bend the pipe to the smallest possible radius, without
deforming the pipe, so that the nozzle, when it has been installed, points inwards and downwards towards
the specific area you want to protect. These couplings are not included in the standard installation kit,
but they can be supplied if you place a special order for the required quantity. Fix the nozzle using a
suitable mounting or a clamp so that the nozzle is not dislodge out of position.
4.4 Couplings
The standard kit includes the following brass clamp ring couplings. (NOTE: If steel pipes are installed,
you must use steel couplings.)
•
Valve hose with nipples (9, 11 och 12 Fig. 9 A and B) used to connect the valve to the piping
(see separate installation instructions enclosed with the hose kit)
•
Straight nozzle coupling (type 4 Fig 9 A) for nozzles (quantity = number of nozzles).
•
T-coupling (type 6, Fig 9 A) for joining pipes or for direct mounting of nozzles using double-
sleeve couplings (type 13, Fig. 9 B).
•
You can also order the required number of angle couplings (2) for direct connection of nozzles.
4.4.1 Coupling Kits
Examples of kits
The standard installation kit includes clamp ring couplings of brass as illustrated on page 10.
(NOTE: If steel pipes are installed, you must use steel couplings.)
