Detector assembly

The detector should be installed in an area where the highest
amount of gas may concentrate, near places where gas leaks
could start and accessible for maintenance work. It is also
advisable to place it away from transit areas or areas where it could be
accidentally knocked.
Different types of gas can have different densities, and this means that
leaks could concentrate in the lowest part of the room or near the roof.
Take this into account when deciding on the height of the detector.
Taking into account the characteristics of the used cooling gas, the
sensors of the detectors used to control the concentration should be
positioned at eye height, with a free distance around them of
approximately 50 cm.
-Remove the detector's cover (Fig. 4).
-Drill the hole for the included gland needed for the cable entry following
the pre-stamped centres on the bottom of the base.
-Drill 3 holes on the wall following the fixing holes. (Fig. 5).
-Fasten the gland onto the base.
-Insert the 3 screws+plugs through the base, into the 3 holes on the wall
and tighten.
-Insert the cables into the gland and connect them according to the
wiring diagram.
-Adjust the alarm/pre-alarm delays using the delay switch (See page 11)
-Insert the cover and gently press it until you hear a "click".

Wiring

Always disconnect the power supply to do the wiring.
The power circuit should be equipped with a switch for its disconnection of at least 2 A, 230 V, situated
near the appliance. The power supply cable should be H05VV-F or H05V-K type. The gauge will depend on local
regulations, but should in no case be less than 1 mm .
Cables for wiring the relay contact should have an adequate section depending on the unit to be connected.
AKO recommends the use of shielded cable for the wiring of the detectors.
