General information
Preface
This manual has been prepared to acquaint the owner and
serviceman with the installation, operation, and mainte-
nance procedures as recommended by Johnson Controls-
Frick
®
for TDS_ Rotary Screw Compressors.
It is most important that these compressors be properly
applied to an adequately controlled refrigerant or gas
system. Your authorized Johnson Controls-Frick represen-
tative should be consulted for his expert guidance in this
determination.
Proper performance and continued satisfaction with these
units is dependent upon:
• Correct installation
• Proper operation
• Regular, systematic maintenance
To ensure correct installation and application, the equip-
ment must be properly selected and connected to a prop-
erly designed and installed system. The Engineering plans,
piping layouts, etc. must be detailed in accordance with
the best practices and local codes, such as those outlined
in ASHRAE literature.
A screw compressor is a vapor pump. To be certain that
it is not being subjected to pumping liquid, it is necessary
that controls are carefully selected and in good operat-
ing condition; the piping is properly sized and traps, if
necessary, are correctly arranged; the suction line has an
accumulator or slugging protection; that load surges are
known and provisions are made for control; operating
cycles and stand still periods are reasonable; and that high
side components are sized within system and compressor
design limits.
It is required that the discharge temperature be kept high
enough to prevent condensation of any moisture in the
compressor and oil separator.
Design limitations
TDS_ compressors are designed for operation within the
pressureandtemperaturelimitswhicharespeciedby
Johnson Controls-Frick and the Johnson Controls-Frick
selection software COOLWARE
™
. 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 the bare compressor that are
available as sales order options: Solenoid Valves, Tank
Drain Tubing (T connection), Oil Feed Line (P connection),
Connection Fittings, Coupling.
Transit damage claims
All claims must be made by the consignee. This is an ICC
requirement. Request immediate inspection by the agent
of the carrier and be sure the proper claim forms are ex-
ecuted. Report damage or shortage claims immediately to
Johnson Controls-Frick Sales Administration Department,
in Waynesboro, PA.
Compressor identication
Each compressor has an identicationdataplate,contain-
ing compressor model and serial number mounted on the
compressor body.
NOTICE
When inquiring about the compressor or unit, or order-
ing repair parts, provide the model, serial, and Johnson
Controls - Frick sales order numbers from the data plate.
