1.8 Functional Overview
The Bacharach Refrigerant Monitor is designed to detect, measure, and display the concentration of refrigerant
gas in the area being monitored. To ensure accurate gas measurements, the monitor self-zeros every 4 minutes
using an external supply of fresh air provided by activated carbon filtering.
During normal operation the Refrigerant Monitor displays both the current gas level and the peak gas level
detected 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 Refrigerant Monitor 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 quickly identify the cause of the fault.

3.1 Front Panel Display and Controls
Halogen Monitor (Bagless PGM-IR)
3.2 Connecting the Zero Air Filter Assembly
A Zero Air Filter Assembly must be installed to properly use the Bacharach Refrigerant Portable Monitor. The
following steps should be taken to install the filter.
1. Unfasten the Velcro on the front of the monitor soft case.
2. Slide the zero air filter into the front pocket. Route the tubing through the hole in the back of the
pocket, along the side of the housing.
3. Insert the elbow connector extending from the Charcoal Filter Assembly into the Zero Air Inlet on
the monitor.
4. Refasten the Velcro.
Instruction 3015-5466 (Rev 10) 9
Halogen Monitor (Bagless PGM-IR)
To connect the elbow connector to the zero air
filter PTC fitting, firmly push the elbow into the
hole in the center of the connector until it seats in
the connector. Refer to the figures at the left.
To remove the elbow from a PTC connector, push
and hold the spring-loaded collar inwards, then
simultaneously withdraw the tubing/elbow. Refer
to the figures at the right.
3.3 Zero Air Filter Service Life
The monitor will periodically (up to 4 minute intervals) draw clean air from an intake port on the side of the
chassis. The external zero air (charcoal) filter (P/N 3015-5722) must be connected to this purge port per Section
3.2 in order to scrub any ambient refrigerant present in the area of operation. When the filter is saturated and can
no longer absorb refrigerant, refrigerant can pass thru and create an offset on subsequent measurements, so
proper filter maintenance is important. The purge intake filter can operate continuously in a 10 ppm ambient for
up to 10 hours before measurement accuracy will be affected. For higher ambient levels the run time is reduced
proportionally. To avoid measurement errors Bacharach recommends the following purge filter replacement
intervals.
Approximate Ambient Refrigerant Level Filter Replacement Interval
0 ppm 6 months
5 ppm 250 hrs
10 ppm 200 hrs
20 ppm 150 hrs
100 ppm 100 hrs
The refrigerant monitor can detect a saturated filter during operation by sampling clean (0 ppm) air after the unit
has been purged in the presence of ambient refrigerant. A fault will occur (0100) if refrigerant is detected on the
purge port.
10 Instruction 3015-5466 (Rev 10)
Halogen Monitor (Bagless PGM-IR)
3.4 Connecting Gas-Sample, Exhaust and Purge Lines
3.4.1 Overview
A single gas-sample line needs to be run from the Refrigerant Monitor to the area to be monitored. If desired,
an optional exhaust line can be installed to vent refrigerant gas away from the monitor.
3.4.2 Connecting the Gas-Sample Line or Probe (Model 3015-5420)
To connect the gas-sample line to the monitor, simply push the tubing onto the elbow connector and attach the
elbow to the Gas Sample Port on the front of the monitor as shown in the illustration below.
The gas-sample line can be up to 50 ft (15.2 m) in length. All tubing bends should have a radius of no less than
5" to insure proper airflow. If kinks or obstructions occur in the line the monitor may not function properly.
NOTE: Every foot of tubing added to the sample probe increases the instrument response time by 1 second.
For best performance use the tubing provided with the instrument when possible.
The end of this line should be placed near the potential leak source and positioned to reduce the possibility of
mists, aerosols, oil, water, dust, or other contaminants being drawn into the monitor.
An ex
ternal filter (P/N 3015-5324) should be attached to the end of this line. See figure on page 11 for details.
3.4.3 Connecting the Gas-Sample Probe 3015-5694
If refrigerant monitor 3015-5696 was ordered the probe assembly is provided pre-assembled. Simply connect
the elbow to the gas sample port. See figure on page 11 for details.
3.4.4 Connecting the Exhaust Line
The optional exhaust line carries the exhausted gas sample away from the monitor. The exhaust line can be up
to 50 ft (15.2 m) in length. Ideally this line should terminate outdoors in a location that is not exposed to the
elements.
Connecting the Gas Sample Line or Probe
Instruction 3015-5466 (Rev 10) 11
Halogen Monitor (Bagless PGM-IR)
Connect the exhaust line to the monitor by firmly pushing the tubing into the Exhaust Port’s push-to-connect
(PTC) fitting. See below. If the exhaust line terminates outside the building, position the tubing so that no water
or moisture can enter the line. Note that this line does not require a termination filter.
To connect the exhaust line to the exhaust port’s
PTC fitting, firmly push the appropriate tubing into
the hole in the center of the connector until it seats
in the connector. Refer to the figures at the left.
To remove tubing from a PTC connector, push and
hold the spring-loaded collar inwards, then
simultaneously withdraw the tubing. Refer to the
figures at the right.
3.4.5 Connecting Zero Air Inlet to an External Purge Line (Optional)
If using the charcoal filter assembly a purge line is not required.
The purge line provides the same function as the charcoal filter, supplying clean air (0 ppm target gas
concentration) into the monitor for the purpose of purging the monitor and setting its baseline reading.
The zero air inlet can be up to 50 ft (15.2 m) in length. This line should terminate in an area known to contain
clean (0 ppm) air. To connect the purge line to the monitor, simply push the tubing into the Purge Air Inlet Port.
If the purge line terminates outside the building, position the tubing so that no water or moisture can enter the
line.
3.5 Gas Detector Operat ion
CAUTION: Operate the monitor in its horizontal position (handle facing upwards). Tilting the
monitor to a vertical position while in operation may cause inaccurate measurements to occur.
Turn ON the monitor as follows:
1. Lift up the shield located in front of the handle
2. Press the green power ON/OFF toggle switch.
3. Observe monitor’s firmware version is briefly displayed.
4. Observe the monitor starts counting down its warm-up period of
300 seconds (5 minutes).
Observe the following as the monitor makes gas measurements in the area being sampled:
• MEASURE indicates when the monitor is actively measuring the level of refrigerant gas at the sampling
point. The measurement cycle runs for 4 minutes.
A log of up to 200 previous measurements can be viewed using the PPM LOG function as described on
page 14.
• PURGE indicates when the monitor is resetting its infrared detector to a baseline of 0 ppm. The purge
cycle runs for 10 seconds.
Work with gas alarms and system faults as follows:
12 Instruction 3015-5466 (Rev 10)
Halogen Monitor (Bagless PGM-IR)
included in the replacement kit, as the new replacement battery and cable may differ from the
ALARM (red) light turns ON if the detected gas level exceeds a programmed alarm point.
An audible alarm also sounds if the AUDALRM function is activated. Pressing the front panel
SILENCE button turns OFF the audible alarm, but the ALARM light will continue to flash for as long
as the detected gas level is above the alarm point. The audible alarm will reactivate if the gas-alarm
condition is not cleared within the time period set by the SILENCE function (refer to text starting on
page 14).
FAULT (yellow) light turns ON if a fault occurs (see Fault Code list on page 18). An audible alarm also
sounds if the AUDALRM function is activated. Pressing the front panel SILENCE button turns OFF the
audible alarm, but the FAULT light continues to flash for as long as the fault is present. The audible
alarm will reactivate if the fault condition is not cleared within the time period set by the SILENCE
function (refer to page 14). Both the FAULT light and audible alarm will automatically turn OFF after
the cause of the fault has been eliminated. A log of the last 30 fault events can be viewed using the
monitor’s FAULTS function (page 17).

3.9 Working with the Gas Alarm (Area Monitoring)
3.9.1 Gas-Alarm Light
If the detected gas level reaches the gas-alarm level as set by the ALRMLVL function, the front panel ALARM
(red) light will flash and the audible alarm, if activated (refer to AUDALRM function in the Function Screens
section on page 15), will start beeping. The ALARM light and audible alarm will automatically turn OFF once the
detected gas level drops below the gas-alarm level.
3.9.2 Silencing a Latching Gas Alarm
Once the gas-alarm circuit has been triggered, all alarm-configured indicators remain turned ON (even after the
detected gas level returns to normal) if the ALM ACK function is set to MANUAL. Press the SILENCE button to clear
all gas-alarm indicators after the cause of the alarm has been cleared and the detected gas level has dropped
below all alarm levels. If the ALM ACK function is set to AUTO, the alarm-configured indicators will automatically
shut off when the gas level drops below its alarm set point.
Pressing the SILENCE button while the alarm circuit is activated causes the audible alarm to turn OFF for a period
of time as set by the SILENCE function. The front panel ALARM light will continue to flash as an indication that
an alarm condition still exists. At the end of the silence period if the detected gas level is still above the gasalarm level the audible alarm will reactivate.
3.10 Working with the Gas Alarm (Leak Detector Option)
3.10.1 Gas-Alarm Light Plus Audio Feedback
When the LEAK DETECTOR option is selected in the AUDALRM menu, the instrument provides a ticking sound via
the internal beeper and flashes the red ALARM LED at a rate proportional to the displayed reading. At 0 ppm the
rate is approximately 1 per second. The range over which the tick sound is scaled is set using the “RANGE” menu
(taking the place of the LEAKLVL menu option).
During a purge cycle the tic sound is suspended to let the operator know that the instrument is not sampling.
Purging typically completes in approximately four seconds.
If power is removed or the product turned off, “Leak Detector Mode” remains set.
It is not possible to silence the Gas Alarm when LEAK DETECTOR operation is selected.
