Figure 26. Evacuation of SD(H) System
4. Initiate the system evacuation.
Evacuate the system down to 400 MICRONS
as read on
the digital micron gage. After 400 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 500 MICRONS WITHIN 30 MINUTES.
If pressure rises to
greater than 500 microns, initiate the evacuation process again and until the above
conditions are met.
A procedure often used to evacuate a system to a deep vacuum level, known as the triple
evacuation method, is detailed in the section of this manual entitled
Triple Evacuation
.
Local codes may require other evacuation criteria, in which case the local codes take
precedence over the evacuation requirements described above.
IMPORTANT!
DO NOT ENERGIZE THE COMPRESSOR WHILE THE SYSTEM IS UNDER
VACUUM. THIS WILL CAUSE DAMAGE TO THE COMPRESSOR.
IMPORTANT!
DO NOT CHARGE THE SYSTEM UNTIL THE CONDITIONS OF STEP #4
ARE COMPLETED!
