4-46. General. This section contains procedures to prepare and place the compressor into short term storage.
Instructions and procedures are also provided to prepare the equipment for shipment.
4-47. Short Term Storage. Short term storage of the compressor, that is storage of about 6 months or less, may be
accomplished by performing the following steps.
WARNING
All work performed on the compressor must be accomplished only while the unit
is depressurized.
a. Run the compressor at operating pressure and temperature for approximately 10 minutes.
b. Check the unit for leaks at all pipe connections, filter, purifier, separator and valves. Tighten couplings and
connections as required.
c. After 10 minutes of operation, open the fill valve and allow the compressed air to escape to the atmosphere. The
compressor will then be maintained at about 2000 PSIG (138 BAR) by the pressure maintaining valve.
d. Shut down the unit after five more minutes of operation and drain off the filter, purifier and separator by opening
their condensate cocks. Close the cocks after compressor has been reduced to zero pressure.
e. Unscrew separator collars and apply a thin film of silicone grease to the male threads on the separator cover and
reinstall collar.
f. Remove top plug from purifier cylinder. Coat threads and preformed packing seals with a thin coat of halo carbon
grease. Notify direct support maintenance to replace the purifier cartridge.
g. Service engine oil bath air cleaner (para. 4-26).
h. Install new compressor inlet air cleaner element (para. 4-18).
i.
Remove prefilter hose and seal opening in air filter housing with plastic bags and secure with tape (Items 3 and 22,
Appendix E).
j.
Drain fuel from fuel tank. Spray interior of tank with a small quantity of preservation oil.
k. Change engine oil (para. 4-23).
I. Change compressor oil (para. 4-16).
