Operating Tips
After the RECOVER function is selected :
• If system pressure is below 10 psi, the
display reads
LOW RECOVER PRESSURE
CHECK CONNECTIONS
until pressure increases, or the START /
YES button is pressed. Verify the high- and
low-side hoses are connected and coupler
valves are open. Press STOP / NO to 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(XXKG)
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.
