1.- Introduction
Refrigerator gas leak detection alarm to be used in refrigerated facilities designed to comply with standard
EN 378-3.
2.- Versions and references
WARNINGS
* The pre-alarm and alarm levels can slighty differ from the values shown in the table depending
on the detected type of gas.
- The alarm and detectors should be installed in a place protected from vibrations, water and corrosive
gases, where the ambient temperature does not exceed the value indicated in the technical data. The
station should be installed in a place where the regular presence of people who can alert to the
presence of alarms is guaranteed.
- To prevent false alarms, the detector should be installed away from:
Maintenance rooms where solvents, paints or refrigerator gases are handled.
Ÿ
Fruit ripening or storage rooms, as some fruits can emit gases.
Ÿ
Smoke outlets located in confined spaces (carbon dioxide, propane, LPG) or from engines,
Ÿ
generators or motorised machinery (fork-lift trucks, etc.).
Particularly damp areas or with the risk of getting wet.
Ÿ
Areas with strong ventilation.
Ÿ
- Do not paint the detector or place it near solvents or paints.
- Neither the alarm or gas detector are suitable for areas classified as potentially explosive.

4.- Equipment description
Alarm station
Mute/reset button
Mutes the alarm or deletes saved alarms
Pre-alarm jumper
It allows deactivating pre-alarm detection.
Before using this option, make sure that
regulations allow for only one alarm level.
Gas detector
Delay switch
It delays the activation of alarms detected in the station.
*Default value.
IMPORTANT: The delay configuration should be carried out with the station's power supply
disconnected, as if not it will not work.
5.- Installation
The wiring between the detector and the station should NEVER be installed
in a conduit together with power, control or feeder cables.
Station assembly
The detector status indicators will indicate the alarms and pre-alarms
immediately, without taking into account the delays.
- Remove the cover T of the equipment (Fig. 1).
- Open the equipment and remove the front of the housing (Fig. 2).
- Drill the holes needed for the cable entry glands using the pre-stamped
centres on the sides of the housing for guidance.
- Drill 3 holes on the wall following the fixing holes 1, 2, 3. (Fig. 3).
- Fasten the glands into the equipment.
- Insert the 3 screws and wall plugs through the housing into the holes in the
wall and tighten.
- Insert the cables through the glands.
- Fit the front of the housing (Fig.2).
- Insert and tighten screws D, F (Fig. 1).
- Connect the cables as shown in the wiring diagram, close the cover T,
insert and tighten screws A, C (Fig. 1).

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.
It is advisable to install the freon detectors around 20 cm from the
ground, with an free distance around them of some 50 cm.
- Remove the detector's cover (Fig. 4).
- Drill the hole for the glands needed for the cable entry following the
pre-stamped centres on the bottom or top 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 10)
- 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
2
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.

Detector heating time
After receiving the electrical power supply, the gas detector needs a heating time of around 5 minutes,
during which it will NOT detect leaks. This time is indicated by means of a quick flashing of the green led
on the detector itself.
Self-diagnosis function
The unit incorporates a self-diagnosis system of the detector and the wiring between the detector and alarm station.
In the case of malfunction, the station will alert making three consecutive tones every 2 minutes, and activating the
visual alarm and the detector status led, while the detector will alternately activate its status leds.

ŸClean the surface of the equipment with a soft cloth, water and soap.
ŸDo not use abrasive detergents, petrol, alcohol or solvents, as this might damage the sensor.
ŸAKO guarantees the correct operation of the detectors during the first 3 years from the date of purchase,
and after this time, it is advisable to replace the detector.
ŸWe recommend changing the detector in the event of having been exposed to high gas concentrations.
The correct operation of the detector should be checked at least once a year, ask about if
your current local regulations require lower intervals.
This check consists of exposing the detector to a small gas concentration and check that
all the relay indications and outputs work correctly.
