EN35422 and EN14624. The Tracer Gas mixture complies with
Article 6, Paragraph 3 of EU Directive 2006/40/EC.

Operating Instructions

1. TURN ON: Press the ON/OFF button once to turn on and again
to turn off. NOTE: Hold button down for approximately 1 second
to turn unit off.

2. WARM UP: The detector automatically starts heating the
sensor. During the heating cycle, the detector will sound a slow
“beep”. Warm up is usually less than 20 seconds.

3. READY: The detector is ready to begin searching for leaks
when the the green Norm sensitivity LED turns on and the audio
“beep” increases in frequency.

Low Battery Indicator

Replace the 4 AA Alkaline batteries when the red LED on the
control panel is lit. Follow battery installation instructions
under Maintenance section.

Adjusting Sensitivity Levels

To choose another sensitivity level, press the Sensitivity button.
The LED below each level will change indicating the new setting.

The Leak Detector will default to the Norm sensitivity level
automatically once the unit comes out of the warm up cycle and
the green LED will turn on.

To change sensitivity levels, press the Sensitivity button once for
HI sensitivity (red LED will turn on) and again for LO sensitivity
(yellow LED will turn on).

Leak Standard Bottle

The leak detector comes with a Leak Test Vial that allows the
user to make sure the detector is performing properly. To test:

1. Remove the plastic seal cap on top of the Leak Test Vial
by pulling it off (see fig. below).

2. Turn on the detector
warm up cycle.

3. Place the sensor close to the small hole in the top of the
Leak Test Vial. The beep rate should increase indicating
that the sensor and electronics are working properly.

4. Replace plastic cap seal after leak test.

Note: Replace the leak standard when the green color is
no longer visible.

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 prope
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

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

Leak Detector detects the hydrogen component of

2

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.
