Leak Size Indicator
The digital leak size indicator remains off normally but once a
leak is detected, a number from 1-9 will be displayed for all
HFC and HCFC refrigerants
regardless of the sensitivity
setting.
The number will continue to increase or decrease depending
on the amount of refrigerant sensed. The maximum value will
be displayed once the leak source has been located. The
table below can be used to approximate the size of leak:
Maximum # displayed
Leak Size (oz/yr)
1 -3
< 0.1
4-6
0.1 to 0.5
7-9 >0.5
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.
Audio Mute Function
To silence or mute the audio beep and alarm signal, press the
MUTE button. To restore the audio sound, press the MUTE
button again. (Note: a few seconds is required to restore
sound if the mute button is pressed in rapid succession.)

Adjusting Sensitivity Levels
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 SENS once for HI
sensitivity (red LED will turn on) and again for LO sensitivity
(yellow LED will turn on).
Leak Test Vial
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 and allow the unit to complete the
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 and the
Digital Leak Size Indicator should display a number from
4-6 indicating that the sensor and electronics are working
properly.
NOTE: Always remember to replace plastic seal cap after
leak test is completed. Replace Test Vial when the green
color is no longer visible.
