Operating Instructions
Note: There are some environmental conditions that might cause an
inaccurate reading: high pollutant environments, large temperature
variations, high wind velocity and environments with large amounts
of freon gasses. Organic solvents, adhesive vapors, fuel gasses and
vesicants will cause an abnormal response from the sensor. Avoid these
environments.
Fast movement of the sensor probe or blowing into the sensor tip will
affect the air ow over the sensor and cause the unit to alarm.
Power-Up & Reset
The ON
OFF button turns this refrigerant leak detector instrument ON, OFF
and serves as an ambient concentration reset button (see ambient
concentration reset for more information).
Press ON
OFF once to turn on the refrigerant leak detector. The LED leak
indicators will then illuminate. Please take note, you have to wait for 1.5
minutes to heat up the sensor for proper functionality.
Press ON
OFF again to reset the ambient concentration for the unit.
Press and hold ON
OFF for 5 seconds to turn the unit OFF. If the unit is left
inactive for 10 minutes it will automatically turn off.
Testing the Unit
Turn the unit ON and set the sensitivity level to “Hi”. Open the cover to the
leak-check bottle and slowly move it closer to sensor tip. If the unit is in
working condition the LED leak indicators will light up, from low to high.
Repeat this process to conrm that the closeness of the leak-check bottle
results in the leak indicators to uctuate from low to high. If the unit does
not perform as stated you must send your unit in for maintenance. For

INSTRUMENTS
Measuring
Position the tip of the sensor probe within 1/4 inch (6 mm) of the
suspected leak source. Slowly move the sensor probe past each possible
leakage point. When the unit detects a leak source an audible tone will
sound and visual indicators will light on the LED leak indicator display,
appearing from left to right; green to orange to red (red being the highest
concentration, green the lowest). Increasing levels indicates the proximity
of the leak location is getting closer. When the unit signals a leakage, pull
the probe away from the leak for a moment and then bring it back slowly
to pinpoint the location. If the refrigerant leak is large setting the sensitivity
switch to LOW (see sensitivity adjustment) will make it easier to nd the
exact site of the leak. Return the sensitivity switch to HIGH before search-
ing for any additional leaks. When you’ve nished testing for leaks turn the
unit OFF and store it in a cool, dry, clean place to protect the sensor and
unit from any possible damage.
Ambient Concentration Reset
This combustible leak detector features an ambient concentration reset
function that sets the unit sensors to ignore the ambient concentrations of
refrigerant present.
Automatic Ambient Setup
When turned ON the unit’s sensor will set itself to ignore the level of refriger-
ant present at the tip. Only a level or concentration great than this will cause
the unit to alarm.
Ambient Reset Feature
Resetting the unit during operation performs a similar function, it programs
the circuit to ignore the level of refrigerant present at the tip of the sensor.
This allows the user to “home-in” on the source of the leak (higher concen-
tration). Similarly, the unit can be moved to fresh air and reset for maximum
sensitivity. Resetting the unit with no refrigerant present (fresh air) causes
any level above zero to be detected.
Note: Be aware that this feature will cause the unit to ignore any
refrigerant present when powered ON. If the unit sensor is pointing
towards a leak when you turn the unit ON the alarm will not sound.

INSTRUMENTS
Sensitivity Adjustment
This unit provides two levels of sensitivity. When the unit is switched
ON it is set to high sensitivity by default. To change the sensitivity, press
the Lo
Sensitivity button. The two left green LED’s will then ash indicating low
sensitivity has been selected. To switch the unit back to high sensitivity,
press the Hi
Sensitivity button. The two right red LED’s will then ash indicating
that high sensitivity has been selected.
Sensor Replacement
To ensure the accuracy of the unit, the sensor must be replaced periodi-
cally. This unit’s sensor has a limited operative period and under normal
operation it should stay operative for over a year. To prolong the sensor’s
life-cycle ensure that the sensor’s surface is free from water droplets,
vapor, oil, grease, dust and any other form of contaminant as well as any
exposure to high density coolants (>30000ppm).
WARNING
When replacing the sensor, the old sensor may be very HOT.
1. Remove the sensor protector cover from the tip of the sensor
probe
2. Pull out the old sensor and insert the new sensor into the plug
(see below)
3. Place the sensor protector over the new sensor
Cleaning
This plastic housing can be cleaned with isopropyl alcohol or standard
household detergents. Do not allow any cleaner to enter the unit or to
come into contact with the sensor as it may cause damage. Gasoline and
any other solvents may damage the plastic and should be avoided.
WARNING: The detergent or isopropyl alcohol could damage the sensor,
be sure to keep them from the sensor when cleaning the unit.

Battery Replacement
Note: When the battery power is running low, the red LED low battery
indicator will illuminate. The batteries should be replaced as quickly as
possible.
1. Loosen the battery cover screw and remove the battery cover
located on the bottom of the instrument as shown below.
2. Install 4 “AA” size alkaline batteries.
3. Replace battery cover by aligning it with the handle and sliding
back onto the unit.
4. Tighten the battery cover screw so the battery cover is
securely into place.
