PREFACE
This manual has been prepared to acquaint the owner and
service person with the
INSTALLATION, OPERATION, and
MAINTENANCE
procedures as recommended by Frick for
RXF Rotary Screw Compres sor Units.
It is most important that these units be properly applied to an
adequately controlled refrigeration system. Your author ized
Frick repre sentative should be consulted for expert guidance
in this determination.
Proper performance and continued satisfaction with these
units is dependent upon:
CORRECT INSTALLATION
PROPER OPERATION
REGULAR, SYSTEMATIC PLANNED MAIN TENANCE
To ensure correct installation and application, the equipment
must be properly selected and connected to a properly de-
signed 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 refrigeration compressor is a
VAPOR PUMP
. To be certain
that it is not being subjected to liquid refrigerant carryover,
it is necessary that refriger ant controls are carefully selected
and in good operating condition; the piping is properly sized
and traps, if necessary, are correctly arrang ed; the suction
line has an accumulator or slugging protec tion; that load
surges are known and provisions made for control; operating
cycles and defrosting periods are reason able; oil return is
controlled; and that high side condenser units control head
pressures and temperatures are within system and compres-
sor design limits.
It is recommended that the entering vapor temperature to
the compressor be superheated to 10°F above the refrigerant
saturation temperature to ensure that all refrigerant at the
compressor suction is in the vapor state.
DESIGN LIMITATIONS
The compressor units are designed for operation within the
pressure and temperature limits as shown in Frick Publica-
tion 070.410-SED.
JOB INSPECTION
Immediately upon arrival examine all crates, boxes, and
exposed compressor and component surfaces for damage.
Unpack all items and check against shipping lists for any
possible shortage. Examine all items for damage in transit.
TRANSIT DAMAGE CLAIMS
All claims must be made by consignee. This is an ICC re-
quirement. Request immediate inspec tion by the agent of
the carrier and be sure the proper claim forms are executed.
Contact Johnson Controls-Frick, Sales Administration
Depart ment, in Waynesboro, PA to report dam age or short-
age claims.
UNIT IDENTIFICATION
Each compressor unit has two identifica tion data plates. The
unit data plate containing unit model, serial number and Frick
sales order number is mount ed on the control panel support
bracket. The compressor data plate containing compres sor
model and serial number is mounted on the compressor body.
NOTE: When inquiring about the compressor or unit, or
ordering repair parts, provide the MODEL, SERIAL, and
FRICK SALES ORDER NUMBERS from these data plates.
