6. Initiate the system evacuation.
Evacuate the system down to 230 MICRONS
as
read on the digital micron gage. After 230 microns has been achieved, turn off the
LP and HP valves and turn “OFF” the vacuum pump
. Reading the digital micron
gage, the system pressure must not exceed 280 MICRONS WITHIN 5
MINUTES.
If pressure rises to greater than 280 microns, open LP and HP valves,
crack the refrigerant valve and allow just enough refrigerant into the system until
20 inches of Hg vacuum is read on the LP gage. Close the refrigerant valve, and
initiate the evacuation process again and until the above conditions are met.

Compressor Models (SC model shown).
