5-14. PRECAUTIONS FOR EXTENDED SHUTDOWN. Whenever the unit is taken out of
service for long periods of time, certain precautions must be taken to prevent general
5-14.1. All interior surfaces of the unit
should be protected against rust by draining
the crankcase and refilling it with a rust
inhibiting oil. The unit should now be op-
erated for fifteen minutes and the oil should
be fogged into the compressor intake, thus
coating all internal surf aces. Leave the
rust inhibiting oil in the crankcase. Note:
When putting the unit back into service, re-
place the rust inhibiting oil with compressor
lubricating oil.
5-14.2. After this operation, all openings
are to be taped shut to prevent moisture
from entering the unit.
