Cautions
aCautions
• 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 BW Technologies by Honeywell
immediately.
• Use only sensor(s) that are specifically designed for the GasAlertMicro 5/PID/IR detectors. Refer to Replacement Parts and
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 ac tivated.
Calibrate if the readings are not within the specified limits.
• BW recommends the combustible sensor be checked with a known concentration of calibration gas af ter any known exposure to
catalyst contaminants/poisons (sulfur c ompounds, 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 ap propriate 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 Sensor Poisons and Contaminants
.
Page 16
GasAlertMicro 5/PID/IR
User Manual
aCautions
• Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond upper scale
limit, which may be hazardous.
• Calibrate only in a safe area that is free of hazardous gas, in an atmosphere of 20.9% oxygen.
• Use only BW approved batteries for the GasAlertMicro 5/PID/IR detectors. Refer to Replacement Parts and Accessories
.
• Charge the detector before first-time use. BW recommends the detector be charged after every workday.
• Charge the battery pack immediately when a low battery alarm occurs.
• Read and adhere to the battery cautions provided in Battery Cautions
.
• Charge the GasAlertMicro 5/PID/IR batteries using the recommended charging adapter only. Do not use any other charging
adapter. Failure to adhere to this caution can lead to fire and/or explosion.
• Read and adhere to all instructions in the charger user manual. Failure to do so can result in fire, electrical shock, personal
injury, and/or property damage.
• Extended exposure of the GasAlertMicro 5/PID/IR detectors to certain concentrations of combustible gases and air may stress a
detector element, which can seriously affect its performance. If an al arm occurs due to high concentration of combus tible gases ,
recalibration should be performed, or if needed, the sensor replaced.
• Protect the PID sensor from exposure to silicone vapors.
• When calibrating O
3
and ClO2 sensors that are located in the Toxic 2 sensor position, a single gas calibration cap must be used
to ensure accurate calibration. For more information, refer to Single Gas Calibration Cap
.
• Replace the CO
2
sensor only in a safe area that is free of hazardous gas.
• The optional pump (M5-PUMP) is certi fied for use with the GasAlertMicro 5/PID/IR detectors only.
• Do not immerse the detector in liquids .
Page 17
GasAlertMicro 5/PID/IR
a
Cautions
aCautions
• Do not test the combustible sensor’s response with a butane cigarette lighter; doing so will damage the sensor.
• Do not expose the detector to electrical shock or severe continuous mechanical shock.
• Do not attempt to disassemble, adjust, or service the detector unless instructions for that procedure are provided in the user
manual and/or that part is listed as a replacement part. Use only BW Technologies by Honeywell Replacement Parts and
Accessories.
• The detector warranty is void if customer, personnel, or third parties damage the detector during repai r attempts. Repair
attempts made by non-BW Technologies by Honeywell repair/service personnel voids this warranty.
Lithium Battery Packs
• Warning: The lithium battery (M5-BAT08) may present a risk of fire or chemical burn hazard if misused. Do not disassemble,
heat above 212°F (100°C), or incinerate.
• Do not use any other lithium batteries with the GasAlertMicro 5/PID/IR detectors. Use of any other cell can cause fire and/or
explosion. To order and replace the M5-BAT08 battery, refer to Replacement Parts and Accessories.
• Warning: Lithium polymer cells exposed to heat at 266°F (130°C) for 10 minutes can cause fire and/or explosion.
• Dispose of used lithium cells immediately. Do not disassemble and do not dispose of in fire. Do not mix with the solid waste
stream. Spent batteries must be disposed of by a qualified recycler or hazardous materials handler.
• Keep lithium cells away from children.

Diagnostics Testing
The detector tests the ambient air (auto zero) and the test gas that is
applied (auto span) to ensure it meets expected values. Auto zero sets
the zero-gas level of the sensor. If ambient gas is present, the zero
level will be incorrect.
If excessive target gas is present, the detector displays an error
message and lists the affected sensor.
In auto span, if the target gas is not d ete cte d or does no t meet exp ect ed
values, a message displays that the detector is exiting cali bratio n mode.
The detector retains the previous set values.
