Long-term storage
Long-term storage, is defined between six months and
ve years. Provisions are required, regardless of storage
environment, if start-up and useful operation does not oc-
cur within six months of equipment shipment. Special pro-
visions may be required for storage of less than 6 months
if the storage area is subject to environments with high
humidity, large changes in temperature, dusty atmosphere,
or other unusual environmental conditions.
The standard Johnson Controls-Frick Warranty for an HPS
273 and 407 screw compressors covers 12 months from
start-up or 18 months from shipment, whichever comes
rst. Make arrangements with the local Johnson Controls-
Frick service organization, arranged through factory
service, regarding surveillance and maintenance during
the storage period. It is the customer’s responsibility to
submit a monthly report showing the condition of the unit
and noting any discrepancies to the guidelines listed in this
manual.
Note: Failure to comply with this long-term storage sug-
gestion may void the warranty.
Long-term storage of equipment may lead to the deterio-
ration 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.
Follow the steps in Preparing the compressor for storage
and Maintaining the compressor in storage to maintain the
screw compressor warranty.
Preparing the compressor for storage
1. Evacuate the compressor to remove moisture.
2. Connect the evacuation lines to the three Schrader
access valves provided with the compressor. One valve
is connected to the compressor suction and the other
two valves are located at the block on the cylinder.
3. Break the vacuum with dry nitrogen and bring pressure
to 0 bar (0 psig).
4. Pump oil into the SM1. Use break-in oil part number
111Q0831809 for storage purposes.
Note: The amount of oil necessary to ll a given compres-
sor model depends on the L/D size involved and
the actual internal clearances of the compressor.
The approximate volume of oil needed to ll the
compressor is between 20 gal to 25 gal for HPS 273
compressors, and 100 gal to 120 gal for HPS 407
compressors.
Note: The gal amount of oil are average values, which
vary based on the specic HPS model.
5. After the compressor is oil charged, pressurize the
compressor to 1.0 bar (14.5 psig) with nitrogen.
