Section 9. Evacuation

9.1 Evacuate the Refrigerant Lines and Indoor Coil

Important:

Do not open the service valves until

the refrigerant lines and indoor coil leak check

and evacuation are complete.

STEP 1

- Evacuate until the micron gauge reads

no higher than 350 microns, then close off the
valve to the vacuum pump.

STEP 2

- Observe the micron gauge. Evacuation

is complete if the micron gauge does not rise
above 500 microns in one (1) minute.

Once evacuation is complete blank off the
vacuum pump and micron gauge, and close the
valves on the manifold gauge set.

1 MIN.
