EXTENDED STORAGE PROCEDURES
If a compressor is not to be put into service for some time, or if a compressor is to be taken out of service for an
extended period, the following procedures should be taken.
1.
Fill the crankcase with rust inhibiting oil. (New compressors are shipped from the factory without oil.)
Squirt oil on the piston rods and crossheads through the nameplate opening. Loosen the V-belts to relieve
the load on the bearings. Rotate the compressor by hand a few times to distribute the oil.
2.
Plug all openings and purge the compressor with an inert gas such as nitrogen or
dry
air at about 50 psig
(3.5 bar-g). This may be done at the factory if requested. Leave the compressor pressurized to prevent
air or moisture from entering the unit.
NOTICE: Tag the unit with a warning that it is pressurized.
3.
If a purge gas is not available, fog oil into the compressor suction while rotating the unit. Then plug all
openings to keep out moisture, insects, etc.
4.
Turn the flywheel by hand a few revolutions once a month to distribute the oil.
5.
Store the unit under a plastic wrap on its wooden shipping base up off the ground. If the unit was boxed
for export shipment, leave it in its box. An indoor or covered storage area is preferable.
6.
When the compressor is to be put in service, vent the remaining purge gas and change the crankcase oil.
See the 'Pre-Startup Checklist' and 'Startup Procedure' sections in this manual.
•
Compressor is pressurized with inert gas.
CAREFULLY bleed off gas BEFORE
attempting any service.
Hazardous pressure can
cause property damage,
serious personal injury
or death.
