Safety Information - Read First

CAUTION

• 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 the technical reference guide completely before operating or servicing.
• Charge the detector before first-time use. BW recommends the detector be charged after every workday.
• Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor exposure to poisons and contaminants. The sensors must be calibrated regularly and at least once every 180 days (6 months).
• Calibrate only in a safe area that is free of hazardous gas in an atmosphere of 20.9 % oxygen.
• 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.
• 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.
• BW recommends that the combustible sensor be checked with a known concentration of calibration gas after any exposure to contaminants/poisons such as sulfur compounds, silicon vapors, halogenated compounds, etc.
• 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.
• Caution: High off-scale LEL readings may indicate an explosive concentration.
• Any rapid up scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond upper scale limit, which can be hazardous.
• For use only in potentially explosive atmospheres where oxygen concentrations do not exceed 20.9% (v/v).
• Extended exposure of the GasAlertMax XT II to certain concentrations of combustible gases and air may stress the detector element that can seriously affect its performance. If an alarm occurs due to a high concentration of combustible gases, recalibration should be performed, or if needed, the sensor replaced.
• The BW pump (XT-RPUMP-K1) is certified for use with the GasAlertMax XT II only.
• Warning: The lithium battery (MX-BAT01) may present a risk of fire or chemical burn hazard if misused. Do not disassemble, heat above 212°F (100°C), or incinerate.
• Warning: Do not use any other lithium batteries with the GasAlertMax XT II detector. Use of any other cell can cause fire and/or explosion. To order and replace the MX-BAT01 lithium battery, contact BW Technologies by Honeywell.
• 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.
• Calibrations and bump tests can be performed using a 0.5 l/min. regulator or a demand flow regulator. If the demand flow regulator is used, it must meet the following maximum inlet pressure specifications:
  • Disposable cylinders 0-3000 psig/70 bar
  • Refillable cylinders 0-3000 psig/70 bar
