● Ground yourself to discharge static electricity before performing
any wiring.
● Do not install the sensor unit in places with direct sunlight or
where the ambient temperature is more than 40 ˚C or is less
than 0 ˚C. Follow specifi cations. (P.6)
● The connecting cable must not touch piping directly.
● Install this sensor unit horizontally.
● The warranty does not cover the product if it falls from an
elevated location.
● The semi-conductor sensor may react or malfunction if
exposed to gases other than the refrigerant gas or to steam.
Accordingly, the following must be avoided when installing.
• Using in atmospheres where silicone gases (siloxane, etc.)
may occur
The sensor unit may malfunction or operate incorrectly if items
such as adhesives, hair products, rubbers, or putties with
silicone in them are used in the vicinity of the sensor.
• Exposing to organic solvents/chloric gases
Alcohols, VOCs, chloric gases, etc., can be the cause of
malfunction or incorrect operation.Large amounts of organic
solvents are produced by paints, fl oor waxes, etc., when
building or renovating structures, so ensure the area is
properly dried and ventilated before installing the sensor.
• Polluting with alkaline metals (especially salt mist)
Precautions for Operation
● Do not block the gas detector. (It will be unable to detect
refrigerant leaks and may result in a fi re.)
● Do not power off the air conditioner even if it is not used for a
long time. The refrigerant sensor will not operate.
● The buzzer starting to sound indicates that there has been a
refrigerant leak. Ignition or fi re may result as the concentration
of refrigerant increases, so the area should be ventilated and
evacuated as quickly as possible.
● If a leak is suspected, all naked fl ames should be removed and
extinguished.
