CAUTION: FOR SAFETY REASONS, THIS EQUIPMENT MUST BE OPERATED AND SERVICED BY QUALIFIED PERSONNEL ONLY. READ AND UNDERSTAND THIS USER MANUAL COMPLETELY BEFORE OPERATING AND SERVICING.
Safety Information – Read First
Use the detector only as specified in this user manual, otherwise the protection provided by the detector may be impaired.
International symbols used on the detector and in this user manual are defined in Table 3.
Read the Cautions on the following pages before using the detector.
ec Warning
This instrument contains batteries. Do not mix with the solid waste stream. Spent batteries must be disposed of by a qualified recycler or hazardous materials handler. Dispose of 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.

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 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).

GasAlertMicro 5/PID/IR aCautions
· 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. aCautions
· Before using common products around sensors, refer to Sensor Poisons and Contaminants.
· High concentrations of certain toxic gases, for example H2S, may have an adverse effect on the LEL sensor. This effect, known as inhibition, is usually temporary but in extreme circumstances can impair the sensitivity of the LEL sensor. After any gas exposure that causes an alarm in the toxic gas sensors, the LEL sensor should be verified with a bump test, and recalibrated if necessary.
· 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.
3

GasAlertMicro 5/PID/IR User Manual

· 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 alarm occurs due to high concentration of combustible gases, recalibration should be performed, or if needed, the sensor replaced.
aCautions · Protect the PID sensor from exposure to silicone vapors.

· When calibrating O3 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 CO2 sensor only in a safe and non-hazardous area that is free of hazardous gas.
· The optional pump (M5-PUMP) is certified for use with the GasAlertMicro 5/PID/IR detectors only.
· Do not immerse the detector in liquids. · 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 repair 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 100°C (212°F), or incinerate.

4

· 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 M5BAT08 battery, refer to Replacement Parts and Accessories.
· Warning: Lithium polymer cells exposed to heat at 130°C (266°F) 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. · Products may contain materials that are regulated for
transportation under domestic and international dangerous goods regulations. Return product in compliance with appropriate dangerous goods regulations. Contact freight carrier for further instructions.

· To disable an alarm, set the alarm setpoint to 0 (zero).
· If the Auto cal option is enabled, the oxygen (O2) sensor calibrates automatically every time the detector is activated. Activate the detector in a safe area that is free of hazardous gas in an atmosphere of 20.9% oxygen.
· After activating the detector, allow it to stabilize for 1 minute before performing a calibration or bump test.
· If a certified calibration is required, contact BW Technologies by Honeywell.
Note
A generator must be used for O3 and ClO2 sensors.

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 detected or does not meet expected values, a message displays that the detector is exiting calibration mode. The detector retains the previous set values.
