Honeywell BW™ Flex 4 Multi-Gas Monitor Quick Reference Guide

General Warnings

Users must read the manual and follow the guidance given. Ensure only qualified personnel use, service, and maintain the monitor. The user must configure instruments before use. It is the user's responsibility to ensure correct operation before use.

Operation

Bump testing before use to ensure correct operation is recommended. Only use the equipment within the certified and operational limits specified. Be aware of possible interference or cross-sensitivities to other gases. Ensure accessories used are compatible with gases to be detected. Do not expose sensors to inhibitors or poisons. Ensure units are charged sufficiently for the day's use. Charge the device in a safe area within the temperature range of 0-45°C. Do not charge devices in direct sunlight.

Maintenance

Inspect equipment for physical damage. Do not use if damaged. Ensure all filters are clear of obstruction/dirt. Replace filters regularly. Clean with a damp cloth using warm water only. Do not apply alcohol/solvent to the instrument; it may cause damage. Only zero in the fresh air or with controlled gas to correct baseline drift. Never attempt to zero an instrument in a hazardous environment. Calibrate the detector per recommendations for each sensor. Maintain bump/calibration records for later inspection. Do not use a "lever" to open the instrument. This will damage the sealing. Replace sensors/batteries as needed to maintain performance. Ensure instrument firmware/software updates are applied routinely. Do not tamper with, heat, or incinerate Li-ion batteries. Spent batteries must be disposed of in compliance with local laws. Only use Honeywell-supplied parts. Alternates will invalidate the warranty.
