WARNING
Handling the sensor unit
Do not disassemble the electrochemical type sensor unit (ESU) because it contains electrolyte.
Electrolyte may cause severe skin burns if it contacts skin, while it may cause blindness if it contacts
eyes. If electrolyte is adhered on your clothes, that part on your clothes is discolored or its material is
decomposed. If contact occurs, rinse the area immediately with a large quantity of water.
Zero adjustment in the atmosphere
When the zero adjustment is performed in the atmosphere, check the atmosphere for freshness before
beginning the adjustment. If interference gases exist, the adjustment cannot be performed properly,
thus leading to dangers when the gas leaks.
Operation in a gas
Do not operate the gas detector in a place where combustible/explosive gases or vapors are present.
Operating the gas detector in such an environment will lead to extreme dangers.
Response to gas alarm
Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on your
judgment.
Fuse
To prevent fire, use a time lag fuse with the specified ratings (3.15A, 250V) for the gas detector.
Turn the POWER switch OFF and disconnect the power plug from the outlet before replacing a fuse. Do
not use an unspecified fuse or short-circuit the fuse holder.
Power cable
To operate the gas detector on 200 VAC system, prepare a power cable that supports 200 VAC.
The power cable is provided only for the case that the power voltage is 100 VAC system (requested).
The provided power cable supports 100 VAC.
Do not touch the pyrolyzer.
The inside of the pyrolyzer reaches high temperature. Do not touch it to avoid burn injury. Do not touch
the pyrolyzer just after power-off because the inside of it is still hot.
