Batteries:
Install Batteries
: Remove screw located at rear end of unit and
flip up the hinged battery door to open as shown. Always insert all
four batteries into the battery compartment in the correct direction.
Note polarity mark on the inside of the battery door for proper
battery orientation (see illustration on page 4).
Sensor:
Filter Replacement
: Unscrew sensor tip as shown to replace filter.
Replace filter whenever it becomes visibly dirty or every 2 to 3
months depending on use.
Note: Never clean dirty filters with a solvent or soap and water.
Always replace with a new filter supplied with the leak detector
or they can be re-ordered from your supplier or distributor.
Sensor Failure Mode:
If the sensor is not working correctly, the H
2
Leak Detector will not come out of the warm-up mode. If this
happens first be sure the sensor is plugged in all the way. If that
does not correct the situation, replace the sensor.
Sensor Replacement
: Remove sensor by pulling out of socket.
Install the new sensor by aligning the notch in sensor cover with the
raised keyway on sensor socket holder (see figure below).
Note: Do not force sensor into socket. Misalignment can
damage the sensor pins.
IMPORTANT: Make sure sensor is fully inserted for proper
operation. The detector will stay in warm-up mode and the on/off
switch will become inoperative if the sensor becomes loose or is
not fully inserted.

Tracer Gas Detection
Tracer Gas consists of a non-toxic, non-flammable,
environmentally friendly (non-polluting) mixture of 5%
hydrogen and 95% nitrogen. For this reason, the Tracer
Gas can be released into the environment after the leak
detection procedure is completed. The Tracer Gas mixture
complies with Article 6, Paragraph 3 of EU directive
2006/40/EC.
The H
2
Leak Detector detects the hydrogen component of
the tracer and because hydrogen molecules are so small, it
is an ideal gas for leak detection.
The Tracer Gas is charged into an empty system at a
pressure of up to but not exceeding the rated system test
pressure. As Hydrogen is lighter than air, always probe
slightly above the suspected leak area.
Once the source of the leak is located and repaired, the
Tracer Gas can be released and the system can be
recharged again with refrigerant.
