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.
