GasAlertMaxXT II
Safety Information – Read First
Use the detector only as specified in this operator’s manual and the technical reference guide, otherwise the protection provided by the detector may be impaired.
Read the following Cautions before using the detector.
a Cautions · 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).

GasAlertMaxXT II
Quick Reference Guide
· 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.
2

· 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

· 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.

Informations sur la sécurité – À lire avant toute chose
de gaz dangereux, dans une atmosphère contenant 20,9 % d’oxygène.
· Le capteur de gaz combustible est étalonné en usine au méthane à une concentration de 50% LIE. Si la surveillance porte sur un autre gaz combustible dans la plage de %LIE, étalonnez le capteur en utilisant le gaz approprié.
· Sur cet appareil, seule la détection de gaz combustible a fait l’objet d’une évaluation des performances par CSA International.
· Protégez le capteur de gaz combustible des expositions aux composés de plomb, aux silicones et aux hydrocarbures chlorés. Bien que certaines vapeurs organiques (comme l’essence au plomb ou les hydrocarbures halogénés) puissent neutraliser provisoirement les performances du capteur, dans la plupart des cas, le capteur retrouvera son fonctionnement normal après étalonnage.
· Si le capteur de gaz combustible a été exposé à des contaminants/poisons (composés de soufre, vapeurs de silicium, produits halogénés, etc.), il est conseillé de vérifier son bon fonctionnement en le mettant en présence d’une concentration connue d’un gaz.
· BW recommande d’effectuer un ” test fonctionnel ” des capteurs, avant chaque utilisation quotidienne, afin de vérifier qu’ils réagissent bien au gaz, notamment lorsque le détecteur est exposé à une concentration de gaz qui dépasse les seuils d’alarme. Vérifiez manuellement que les alarmes sonore et visuelle sont activées. Étalonnez l’appareil si les lectures sont en dehors des limites spécifiées.
· Précaution: Des lectures élevées hors échelle peuvent indiquer la présence d’une concentration explosive.
