2 Important Notices on Safety 2-2. Warning cases
GX-8000 - 4 -
2-2. Warning cases
WARNING
Sampling point pressure
The gas monitor is designed to draw gases around it under the atmospheric pressure. If
excessive pressure is applied to the gas inlet and outlet (GAS IN, GAS OUT) of the gas monitor,
detected gases may be leaked from its inside, thus leading to dangers. Be sure that excessive
pressure is not applied to the gas monitor while used.
Do not connect the gas sampling hose directly to a location with a pressure higher than the
atmospheric pressure. The internal piping system may be damaged.
Fresh air adjustment in atmosphere
When the fresh air adjustment is performed in the atmosphere, check the atmosphere for freshness
before beginning the adjustment. If other gases exist, the adjustment cannot be performed properly,
thus leading to dangers when the gas leaks.
Response to gas alarm
Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on
your judgment.
Battery level check
Before use, check that there remains sufficient battery power. When the gas monitor is used for
the first time or is not used for a long period, the batteries may be exhausted. Either fully charge
the batteries or replace them with new ones before use.
If a low battery voltage alarm occurs, gas detection cannot be conducted. If the alarm occurs
during use, turn off the power and promptly charge the batteries in a non-hazardous area.
Others
Do not throw the gas monitor into fire.
Do not wash the gas monitor in a washing machine or ultrasonic cleaner.
Do not block the buzzer sound opening. No alarm sound can be heard.
Do not remove the battery unit while the power is ON.
