Connecting The Exhaust Line; General Operation - Bacharach Halogen Monitor Instruction

Operation

2.2.3 Connecting the Exhaust Line

The exhaust line carries the exhausted gas sample away from the monitor, and is required if the monitor
is located in a confined, poorly ventilated area.
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.
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.

2.3 General Operation

WARNING: 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.
To turn ON the monitor, lift up the shield located in front of the handle and press the red power ON/OFF
toggle switch.
When the monitor has been powered ON, allow it to warm up for 5 minutes.

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.
MEASURE indicates when the monitor is actively measuring gas. The
screen to the left shows that currently 10 ppm of R-134A refrigerant gas is
being detected, and that a peak measurement of 20 ppm has been made.
