4. OPERATION GUIDE
(1) The refrigerant leak detector unit is not equipped
with anti-explosive designs and measures. Do not use
this unit in the environment with the burnable gases.
(2) There are some environmental condition that might
cause the error reading:
Pollutant places.
Large temperature variation.
Places with high wind velocity.
Organic solvent, adhesive vapor, fuel gas and
vesicant will cause abnormal response from the
sensor. Try to avoid the environment involved with
this substance.
Places fill with too much to Freon Gas.

6. GETTING STARTED
6-1 Installing Batteries
Loose the screw and remove the battery
compartment door located on the bottom of the
instrument As show below (Fig.1).
Install 4 “AA” size alkaline batteries.
Reinstall the battery cover by aligning it with the
handle.
When the batteries are nearing the end of their useful
life, the Red LED Low Battery indicator illuminates. The
batteries should be replaced as quickly as possible.

6-2 Automatic Ambient Reset Feature
The Refrigerant leak detectors feature an Automatic
Ambient Reset function that sets the unit to ignore
ambient concentrations of refrigerant.
Automatic Ambient Setup - Upon initial power on,
the unit automatically sets itself to ignore the level
of refrigerant present at the tip. Only a level, or
concentration, greater than this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to
ignore any refrigerant present at turn on. In other
words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be
indicated!
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. This allows the user to 'home-in' on the
source of the leak (higher concentration). 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.

6-3 Feature Sensitivity Adjustment
The Instrument provides two levels of sensitivity.
When the unit is switched on, it is set to the high
sensitivity level.
To change the sensitivity, press the key.
When the key is pressed, the visual display will
momentarily show the two left LED's (green)
indicating Low Sensitivity level is selected.
To switch back to High Sensitivity, press the
key. The two right LED's (red) will light momentarily
indicating high Sensitivity level is selected.
7. OPERATING PROCEDURE
WARNING!
Do not operate this instrument in the
presence of gasoline, natural gas, propane,
or in other combustible atmospheres.
zHow To Find Leaks?
NOTE: A sudden whipping of the leak detector probe
or "blowing" into the sensor tip will affect the air flow
over the sensor and cause the instrument to alarm.
(1) Power-Up & Reset function key:
The key turns the Refrigerant leak detector
instrument ON or OFF and reset function.
