9-2. How to clean
Clean the gas detector if it becomes extremely dirty. The gas detector must be turned off while cleaning it.
Use a waste cloth or the like to remove dust. Do not use water or organic solvent for cleaning because
they may cause malfunctions.
NOTE
•
When the gas detector gets wet, water may remain in the buzzer sound opening or grooves. Drain
water as follows:
(1) Wipe away moisture on the gas detector thoroughly using a dry towel, cloth, etc.
(2) While holding the gas detector firmly, shake it about ten times with the buzzer sound opening
facing downward.
(3) Wipe away moisture coming out from the inside thoroughly using a towel, cloth, etc.
(4) Place the gas detector on a dry towel, cloth, etc. and let it stand at normal temperatures.
CAUTION
•
When cleaning the gas detector, do not splash water over it or use organic solvents such as
alcohol, benzene, etc. on it. Otherwise, it may cause discoloration or damage to the surface
of the gas detector or a sensor failure.
