6-3. How to clean
Clean the gas monitor if it becomes extremely dirty. The gas monitor must be turned off while cleaning it.
Use a waste cloth to remove dust. Do not use water or organic solvent for cleaning because they may cause
malfunctions.
Because an extremely large amount of dust inside the gas sampling hose may disturb the gas detection, it
must be cleaned with dry AIR, etc.
NOTE
When the gas monitor gets wet, water may remain in the buzzer sound opening or clearances. Drain
water as follows:
(1) Wipe away moisture on the gas monitor thoroughly using a dry towel, cloth, etc.
(2) While holding the gas monitor 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 monitor on a dry towel, cloth, etc. and let it stand at normal temperatures.
6-4. Parts replacement
<Replacement of Consumables>
Sensor Replacement
The built-in sensors of the gas monitor have a validity period and must be replaced regularly (within two
years).
The sensor life has expired if, for example, the sensors cannot be calibrated in span adjustment, the
readings do not come back after fresh air adjustment, or the readings fluctuate. Contact RIKEN KEIKI. The
warranty period is one year for all the sensors.
Dust Filter Replacement Procedure
Because the dust filter may gradually get dirty or clogged over the time, it must be replaced regarding the
operating conditions. Check the dust filter, and then replace it as necessary.
The gas monitor has various built-in filters.
Gas sampling probe
The gas sampling probe has a built-in Teflon filter. Replace the filter when it has absorbed water, has a low
flow rate, or looks significantly contaminated.
(1) Hold the transparent part and turn the tip (white) to
remove it.
(2) Take out the filter from the transparent part and insert
a new filter.
(3) Attach the tip that has been removed.
CAUTION
When cleaning the gas monitor, do not splash water over it or use organic solvents such as alcohol
and benzene on it. The surface of the gas monitor may be discolored or damaged.
Replacement
CAUTION
Make sure that the filter is inserted in correct
orientation.
