Cautions
To avoid possible damage to the detector:
⇒ Extended exposure of the GasAlertMax to certain concentrations of combustible gases and air may stress a detector element,
which can seriously affect its performance. If an alarm occurs due to high concentration of combustible gases, recalibration
should be performed, or if needed the sensor replaced.
⇒ Exposure to some substances (e.g., silicones, phosphates, lead, or sulfur containing compounds) can cause LEL sensor sensitivity loss.
⇒ Do not test the combustible sensors response with a butane cigarette lighter.
⇒ Do not expose the detector to electrical shock and/or severe continuous mechanical shock.
⇒ Do not attempt to disassemble, adjust, or service the detector unless instructions for that procedure are contained in the manual
and/or that part is listed as a replacement part. Use only BW Technologies
replacement parts.
⇒ Do not immerse the detector in liquids.
⇒ The detector warranty will be voided if customer personnel or third parties damage the detector during repair attempts. Non-BW
Technologies repair/service attempts void this warranty.
