TECHNICAL DATA
Condition Possible Problem Possible Solution
Unit will not turn ON
Unit not properly plugged in or
no power at power source Check power cord to ensure properly
plugged into power source and IEC inlet
Defective Power Switch or PCB Replace defective electrical component
Recovery process is slow
Clogged Filter Check INLET port filter, clean or replace
Valve core on system being
recovered not fully depressed
Check core depressor on connecting
hoses
Compressor seals are worn Rebuild compressor, replace piston seal
Unit does not pull a vacuum
Loose hose connections on Inlet
Side Tighten hose connections
Compressor seals are worn Rebuild compressor, replace piston seal
Hoses are not tight Tighten hoses
Leak in HVAC/R system Find and repair leak in system
Unit running sluggish Low voltage to unit Check power supply
Unit runs but shuts off after
short time
Restriction on discharge side
tripping the high pressure
switch
Check for restrictions
1) Tank valves
2) Schrader cores
Selector valve in correct position
Vacuum switch won’t reset Switch needs to reset Pressurize inlet port

2 Flashes
Optional Tank Over-
fill
Sensor has been
activated
Tank overfill sensor has activated, recovery tank is full and needs to be replaced.
Tank overfill sensor cord not connected. Either connect to a recovery tank
equipped with overfill sensor or install a shorting plug on the end of the Tank
Overfill Sensor cord.
3 Flashes High Pressure Switch
has
been activated
Pressure on the discharge of the unit exceeded 517 PSIG. Check to make sure all
valves in the discharge pathway are open. Once corrected, the pressure switch
will reset.
Excessive pressure in recovery tank. Replace recovery tank.
4 Flashes
Motor Overload
Let cool down for 15 minutes and restart.
Compressor Mechanism is jammed. Repair will be required to fix the compres-
sor mechanism.
5 Flashes
Low Voltage
Detected
Check to see if power source is in the range of the nameplate rating.
6 Flashes
High Voltage
Detected
Check to see if power source is in the range of the nameplate rating.
