filter clogging and extend sensor life. DO
NOT allow the unit to ingest moisture.
Use of the supplied rubber probe tip helps
prevent moisture from being drawn into
the unit. Check ports for moisture before
inserting the probe.
2. After locating and repairing any leaks
requiring the use of the LARGE switch
setting, switch to the MEDIUM setting
and verify the system is free of leaks. For
HFC refrigerants only (such as R134a),
you also must verify the system is leak
free using the SMALL setting. For CFC
and HCFC systems (such as R11, R12,
R22, R123), the MEDIUM setting is suf-
ficient to verify that the system is free of
leaks that require repairing.
Caution: Equipment Damage Hazard
A. Submerging the probe in liquid will damage
the air pump.
B. Exposing the probe to a stream of pure refrig-
erant coming out of a tank will severely reduce
the life or destroy the sensor. Life of this rare-
earth sensor technology is directly proportional to
the amount of refrigerant that passes through it.
With normal intermittent service, the sensor can
last for one year or longer.
C. Exposure to high concentrations of refrigerant
may require adjustment of sensor heat. To check,
repeat the test procedure in “Heater Adjustment”
section.
