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 a
408 mm screw compressor covers twelve (12) months from
start-up or 18 months from shipment, whichever comes
first. 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 flooded 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.johnsoncontrols.com/
frick, for specific 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 Schrader valves provided with the
compressor. One valve is connected to compressor suction.
The other valves are located on the cylinder.
