Read Before Operating
This gas monitoring system has been designed to provide long-term reliable performance. We recommend the
following basic precautions while installing, operating and maintaining this device.
Read this “Guide to Operation and Installation” carefully. Installation, maintenance, calibration and testing
should be performed by qualified personnel only.
Check if the power supply matches the specifications given in this guide and ensure that the system has been
connected properly. This monitor must be powered by a regulated 24VDC power supply.
Please insure the proper polarity. Reversing the polarity will damage the fuse on the drive PCB.
After power up, please let the system equilibrate a few hours before making any adjustments.
The methyl bromide monitor is designed for safety monitoring where normal use is defined as zero gas
concentration with an occasional excursion. If the monitor is continuously exposed to methyl bromide or if the
monitor is exposed to very high short term gas concentrations, it will require more frequent sensor cell
recharges, and complete pyrolizer filament and pump replacement.
Exposing the methyl bromide monitor to continuous levels of sulfur dioxide (SO
2
) from produce in cold
storage facilities will shorten the life of the gas sensor. This may require the need for annual gas sensor
replacement.
The pyrolizer filament is fragile and must never be disturbed once inside the pyro tube. Never twist the
filament inside the pyro tube.

This system has a built-in pyrolizer. The pyrolizer insulation temperature can reach
150 F and can cause burns if touched. Use Caution when working near the pyrolizer.
