Storage and Disposal
7-1. Procedures to store the gas monitor or leave it for
a long time
The gas monitor must be stored under the following environmental conditions.
• In a dark place under the normal temperature and humidity away from direct sunlight
• In a place where gases, solvents or vapors are not present
Store the gas monitor in a shipping carton, if any, in which the product was delivered.
Store the gas monitor away from dust, etc. if the shipping carton is not available.
NOTE
• If the gas monitor with a Li-ion battery unit is not used for a long time, it is recommended to store it
after discharging the batteries until the battery level icon shows one battery mark or so. If the gas
monitor is stored with the batteries fully recharged, the batteries get deteriorated more quickly and may
have shorter life.
• If the gas monitor with a dry battery unit is not used for a long time, store it after removing the batteries.
Battery leaks may result in fire or injury. If the gas monitor is not used for a short time, store it without
removing the batteries. While the power of the gas monitor is OFF, the sensor is energized at all times.
Therefore, it is necessary to store the gas monitor with the batteries in it.
7-2. Procedures to use the gas monitor again
CAUTION
If the gas monitor is not used for a long time, turn on the power at least once every six months and
check that the pump draws in air (about three minutes). The gas monitor, when not activated for a
long time, may cease to work because of hardening of the grease in the pump motor.
CAUTION
When you use a stopped/stored gas monitor again, do not forget to perform a gas calibration. For
information on readjustment including gas calibration, please contact RIKEN KEIKI.
