Safety Precautions
To ensure safe operation, follow the precautions below.
When a gas alarm activates, immediately take all the necessary
measures to prevent an explosion.
Air adjustment (zeroing) starts automatically when the detector is
turned on. Make sure to turn on the detector in clean air. Failure
to do so may cause incorrect air adjustment which will then lead
to inaccurate measurement being displayed.
This product is safety equipment. Perform a routine check before
use (page 35 “Routine Check”).
Do not cover any gas detection ports with any fabric, etc. If
blocked, correct detection is not possible.
Do not block the speaker opening. If blocked, the audible alarm
will be muffled.
Keep the filter elements at the gas detection ports clean and dry.
If the filter elements are dirty or wet, proper gas detection is not
possible.
The recommended sensor replacement cycle is two years. The
sensor may fail to provide accurate detection after two years, and
should be replaced.
Use the specified battery. Use of batteries other than specified
may impair the product’s intrinsically safe characteristics (page 28
“Battery Replacement”).

C
Conditions of use:
・
Replace the battery in a non-hazardous area.
・
Charge the battery in a non-hazardous area.
・
Charge the battery with a specified battery charger (BC-9).
・
Do not separate XA-4400ll and BP-4000llAL or BP-4000llMH when an explosive
gas atmosphere may be present.
・
To prevent accidents from electrostatic charges, wear anti-static working clothes
and conductive footwear (antistatic working shoes). Additionally the work floor
should be conductive (leak current: 10M ohm or less).
・
When the Energizer Type E92 AAA LR03 is used, the ambient temperature
range is -18 to +50
C.
・
The enclosure of this detector uses ABS resin. Avoid exposure to organic
solvents, strong acids, strong alkalis and mineral oils. Exposure may
compromise the explosion-proof structure of the detector.
