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 find the
exact site of the leak. Return the sensitivity switch to HIGH before search-
ing for any additional leaks. When you’ve finished 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.
