Caution
To avoid possible damage to the detector:
⇒ Extended exposure of the detector 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.
⇒ Do not test the combustible sensors response with a butane cigarette lighter; doing so will damage the sensor.
⇒ 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.
