1.7 Shipping Precaution
When shipping the instrument by air, deflate the purge-air bag to prevent it from bursting due to changes
in air pressure. Deflate the bag by selecting the
EMTYBAG
function as described on page 10.
1.8 Features & Capabilities
Detects and measures CFC, HCFC, HFC and halogen gases
Measures all gases up to 10,000 ppm with a sensitivity of 1 ppm
Automatically logs up to 200 gas readings that can be later be recalled for analysis
Eliminates false alarms with use of non-dispersive IR source and sample draw system
Visual and audible gas alarm indictors that are turned ON when the detected gas level exceeds
a user defined trip-point
Extensive self diagnostics, providing both visual and audible indications when a fault occurs
Battery powered, providing from 8–12 hours of operation
1.9 Functional Overview
1.9.1 General Description
The Bacharach Refrigerant Monitor is a portable refrigerant gas monitor. The unit is designed to test for a
specific refrigerant gas for the purpose of determining the presence and level of that gas being tested.
The monitor self-zeros every 4 minutes to ensure accurate gas measurements.
During normal operation the HM unit displays the type of gas being monitored; along with displaying both
the current gas level and the peak gas level detected in that area on its front panel LCD. The monitor
retains a log of previous readings that can be easily accessed at a later time for analysis.
Front panel indicators and an audible alarm are provided to signal gas alarm and instrument fault
conditions. The audible alarm can temporarily be silenced by a push of a button, but will reactivate if the
gas level is still above the alarm trip point after a user defined time period has elapsed.
The HM unit requires only minor periodic maintenance such as the occasional replacement of filters. The
monitor incorporates active diagnostics that continuously check the system for proper operation. A front
panel indicator is provided to alert an operator of system malfunctions, and fault codes are generated that
enable the operator to identify the cause of the fault.
1.9.2 Response to the Presence of Multiple Refrigerants
The HM is a refrigerant level monitor, not a gas analyzer. You must program the monitor to test for a
specific refrigerant, and it will only return accurate concentration readings for that particular refrigerant.
When other types of refrigerant gas are present, the monitor may return incorrect readings.
Most applications only require detection of a single refrigerant and the problems that are associated with
monitoring multiple gases are rarely an issue. If there is a possibility of multiple refrigerants leaking in the
same sampling zone, then you should carefully consider which refrigerant compound you program the
unit to monitor.
