Instruction 3015-5466 (Rev 6)
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 Operation
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:
