8-2. How to clean
Clean the detector if it becomes extremely dirty. The 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.
Because an extremely contaminated inside of the taper nozzle may disturb the gas detection, it must be
cleaned with dry air, etc.
NOTE
•
When the detector gets wet, water may remain in the buzzer sound opening or grooves. Drain water
as follows:
(1) Wipe away moisture on the detector thoroughly using a dry towel, cloth, etc.
(2) While holding the 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 detector on a dry towel, cloth, etc. and let it stand at normal temperatures.
8-3. Parts replacement
Hydrophobic filter replacement procedure
Continuing to use the detector may cause the hydrophobic filter to be contaminated or clogged.
Replace the hydrophobic filter if it becomes extremely dirty.
Also, replace the hydrophobic filter when it has absorbed water or has a lower flow rate.
1
Turn the cap counterclockwise and
remove it.
2
Remove the rubber seal from the cap.
The hydrophobic filter is installed in
the rubber seal.
CAUTION
•
When cleaning the 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 detector or a sensor failure.
