LONG TERM STORAGE
Long term storage (6 months to 5 years) provisions are
required, regardless of storage environment, if start-up
and/or useful operation does not occur within six (6) months
of equipment shipment. Special provisions may be required
for storage of less than six (6) months if the storage area is
subject to unusual environment such as high humidity, large
changes in temperature, dusty atmosphere, etc.
The standard Johnson Controls-Frick Warranty for an SGC/
SGX screw compressor covers twelve (12) months from
start-up or 18 months from shipment, whichever comes
rst.Itisrecommendedthatarrangementsbemadewith
the local JOHNSON CONTROLS-FRICK service organization
(arranged through factory service) regarding surveillance
and maintenance during the storage period. It will be the
customer’s responsibility to submit a monthly report
showing the condition of the unit and noting any
discrepancies to the guidelines listed herein. Failure to
comply with this Long Term Storage Recommendation may
void the warranty.
Long term storage of equipment may lead to the
deterioration of components over the period of time.
Synthetic components in the compressor may deteriorate
overtimeeveniftheyarekeptoodedwithoil.Awarmand
dry environment is essential to minimize environmental and
corrosion damage. Long term storage of the affected
equipment at a customer’s site may involve additional
requirements and interested parties should refer to the
JohnsonControlswebsite,www.jci.com/frick,forspecic
instructions (Location: Bare Compressors\General\
Warranties\Screw Compressor Purchased for Long Term
Storage).
The following guidelines must be followed to maintain the
SCREW COMPRESSOR WARRANTY.
PREPARING COMPRESSOR FOR STORAGE
Evacuate compressor to remove moisture. Evacuation lines
are to be connected to port SM1. Evacuation lines are to be
connected to the three Schrader access valves provided
with the compressor. One valve is connected to compressor
suction. The other two valves are located at the block on
the cylinder.
Break vacuum with dry nitrogen and bring pressure to zero psig .
Pump oil into the same ports mentioned in step 1. Johnson
Controls-Frick recommends break-in oil P/N 111Q0831809
for storage purposes. The amounts of oil needed per
compressor are:
95mm* 2 Gal. 233mm 15 Gal.
120mm* 3 Gal. 283mm 25 Gal.
163mm* 8 Gal. 355mm 35 Gal.
193mm 12 Gal. 408mm 50 Gal.
After compressor is oil charged, pressurize compressor to
15 psig with nitrogen.
MAINTAINING COMPRESSOR IN STORAGE
• Ensure that the 5-15 psig nitrogen charge is maintained
with 15 psig preferred.
• Rotate the male rotor shaft every two weeks. Mark the
shaft to ensure the rotor does not return to the original
position.
