Acautions - Honeywell GasAlertMicro 5 User Manual

• Warning: Substitution of components may impair Intrinsic Safety.
• Caution: For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and understand
this user manual completely before operating or servicing.
• Do not use the detector if it is damaged. Inspect the detector before using. Look for cracks and/or missing parts.
• If the detector is damaged or parts are missing, contact
• Use only sensor(s) that are specifically designed for the GasAlertMicro 5/PID/IR detectors. Refer to
Accessories.
• Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor exposure to poisons
and contaminants. Sensors must be calibrated regularly and at least once every 180 days (6 months).
• BW recommends to bump test the sensors, before each day's use, to confirm their ability to respond to gas by exposing the
detector to a gas concentration that exceeds the alarm setpoints. Manually verify that the audible and visual alarms are activated.
Calibrate if the readings are not within the specified limits.
• BW recommends the combustible sensor be checked with a known concentration of calibration gas after any known exposure to
catalyst contaminants/poisons (sulfur compounds, silicon vapors, halogenated compounds, etc).
• The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in the % LEL range,
calibrate the sensor using the appropriate gas.
• Warning: High off-scale LEL readings may indicate an explosive concentration.
• Only the combustible gas detection portion of this instrument has been assessed for performance by CSA International.
• Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons. Although certain
organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor performance, in most
cases, the sensor will recover after calibration.
• Before using common products around sensors, refer to
