SBTP Rotary Screw Compressor
Installation - Operation - Maintenance
General information
Note:
The information in this document is subject to
change without notice.
This manual has been prepared to acquaint the owner and
servicer with the Installation, operation, and maintenance
procedures as recommended by Johnson Controls-Frick
®
for SBTP Rotary Screw Compressors.
It is most important that these compressors are correctly
applied to an adequately controlled refrigerant or gas
system. Consult your authorized Johnson Controls-Frick
representative for expert guidance in this determination.
Effective performance and continued satisfaction with
these units depends on the following factors:
• Correct installation
• Correct operation
• Regular, systematic maintenance
To ensure correct installation and application, select
the appropriate equipment and connect to a correctly
designed and installed system. The engineering plans,
piping layouts, and other system design materials must be
detailed in accordance with the best practices and local
codes, such as those outlined in ASHRAE and API litera-
ture.
A screw compressor is a vapor pump. To ensure that
working fluid in the liquid state is not being ingested, per
-
form the following checks:
• Select controls carefully. Make sure they are in good
operating condition.
• Size piping and arrange traps correctly, if they are
necessary.
• Check that the suction line has an accumulator or slug-
ging protection.
• Know the load surges and make provisions for control.
• Check that operating cycles and stand still periods are
reasonable.
• Size high-side components within system and com-
pressor design limits.
It is necessary to keep the discharge temperature high
enough to prevent condensation of any moisture in the
compressor and oil separator.
Design limitations
Frick compressors are designed for operation within the
pressure and temperature limits which are specified by
Johnson Controls-Frick and our CoolWare
™
selection soft-
ware. They are primarily used for compressing refrigerant
gas and most hydrocarbon gasses.
If your application is for sour gas, there are special re-
quirements to protect the compressor. Contact Johnson
Controls-Frick Compressor Engineering for application
details.
Job inspection
Immediately upon delivery, examine all crates, boxes, and
exposed compressor and component surfaces for damage.
Unpack all items and check against shipping lists for any
discrepancy. Examine all items for damage in transit.
Standard bare compressor
Items not included with bare compressor that are available
as sales order options include a solenoid valve block, and
solenoid valves.
Transit damage claims
All claims must be made by consignee. This is an ICC
requirement. Request immediate inspection by the agent
of the carrier and be sure the correct claim forms are ex-
ecuted. Report damage or shortage claims immediately to
Johnson Controls-Frick Sales Administration Department,
Waynesboro, PA.
Compressor identification
Each compressor has an
identification data plate, contain
-
ing compressor model and serial number mounted on the
compressor body.
NOTICE
When inquiring about the compressor or unit, or
ordering repair parts, provide the model, serial, and
Frick sales order numbers from the data plate. See
