Introduction
Safety Precautions
To ensure safe operation, follow the precautions below.
Only use this product in accordance with
the applicable laws and regulations.
When a gas alarm is activated, immediately take all the necessary
measures to prevent accidents including gas explosion and oxygen
deficiency.
or toxic gas may be discharged from the gas
outlet. Do not inhale.
High concentration combustible gas may be discharged from the gas
outlet. Do not place the gas outlet near an ignition source.
DANGER
Turn on the gas detector in clean air. Zero adjustment (20.9%
adjustment for oxygen) is automatically done during the powering-up.
Ensure that the zero adjustment is done in clean air. Inaccurate gas
concentrations will be indicated if the zero adjustment is done in a
gas atmosphere.
Do not block any gas inlet and outlet. If blocked, normal detection is
not possible.
Avoid water intake. Water entering the gas sampling tube or gas
detector will impair proper gas detection, leading to product failure.
Do not block the audio opening. If blocked, the audible alarm will be
muffled.
Keep the filter element at the drain filter clean and dry. If the filter
element is dirty or wet, proper gas detection is not possible.
The recommended sensor replacement cycle is three years for
combustible gas sensor (two years for oxygen sensor). The sensor
may fail to provide accurate detection after three years (two years for
oxygen sensor), and should be replaced.
See “Annual Inspection” on page 45.
Only use specified batteries. Using batteries other than those
specified may impair the product’s explosion-proof performance.
