BATTERY TEST

Turning the unit ON will automatically run

the battery function test and display the

battery condition on the UNITS LED display.

To view the remaining battery life, press

and hold the ON/OFF button.

OPERATING PROCEDURES

1. SENSITIVITY LEVELS

55100 offers three sensitivity levels (Low-Med-High). It will detect leaks as low as 1/10 oz (3 grams) per

year. Turn ON the unit, it will default to the Medium Level. (The Medium Level is the recommended setting to

begin inspection). To view the sensitivity level on the LED display, press either the UP or DOWN arrow. The

LED display will illuminate for approximately two seconds. Two Red LEDS will progressively illuminate for

every sensitivity level.

The sensitivity level can be increased by the UP arrow and decreased by the DOWN arrow. Pressing the

selected arrow once will adjust the sensitivity to the next level. Pressing and holding the arrow will continue

to move the setting until the arrow is released.

2. DETECTION LEVELS

55100 offers 5 levels of detection. As the unit approaches the leak source and the refrigerant concentration

increases, the audible alarm will increase in speed and the LED will display 5 levels of detection.

The detection level will vary depending on the level of the sensitivity setting. The same size leak will display

higher detection levels in higher sensitivity settings and lower detection levels in the lower sensitivity

settings.

3. RESET FUNCTION

The primary use for the RESET function is to pinpoint the leak source. When the unit detects a leak and goes

into full alarm, press the RESET button. Resetting will ignore any leaks at that level and only detect leaks of

higher concentration.

IMPORTANT LEAK DETECTION TIPS:

A. Make sure that the air conditioning/refrigeration system is turned OFF before inspection. A sufﬁcient

amount of refrigerant must be present in the system. A minimum gauge pressure of 50 PSI at ambient

BATTERY INSTALLATION

Hold the leak detector handle horizontally.

To remove the battery door, loosen the screw on top of the door and

pull the door away from the unit. Load the two “C” cell batteries into the

compartment with the positive (+) end up. Reinstall the battery door.
