Note: The machine gives an alert when the oil drain
bottle needs to be emptied, but it is a good practice
to completely empty the oil drain bottle before
recovering an A/C system to prevent an inaccurate
oil charge later.

Operating Tips
After the RECOVER function is selected :
• If system pressure is below 10 psi, until pressure
increases, the display reads
LOWRECOVERPRESSURE.
PLEASECHECKVALVESAND
CONNECTIONS.
SELECTYESTOCONTINUEWITH
RECOVERORSELECTVACUUM.
THEEXITKEYABORTSTHEFUNCTION.
Verify high- and low-side hoses are connected
and coupler valves are open. Select Yes to
recover, select Vacuum to bypass recover,
or select Exit.
• If 100 lbs. (45 kg) or more of refrigerant has
been recovered since the last lter-drier
change, the display reads
FILTERWEIGHTXXXLB
To meet SAE J-2788 requirements, it is
mandatory to replace the lter-drier after
150 lbs. (68 kg) of refrigerant has been
ltered. The unit gives a warning to replace
the lter when lter weight reaches 100 lbs.;
when lter weight reaches 150 lbs., the unit
locks out and ceases to operate. Refer
to instructions outlined in the Maintenance
section under Replace the Filter-Drier.
