PREFACE
This manual has been prepared to acquaint the owner and
serviceman with the INSTALLATION, OPERATION, and
MAIN TEN ANCE procedures as recommended by Frick
®
for
RWB II Rotary Screw Compres sor Units.
For information about the functions of the electrical control
panel, communications, specifi cations, and wiring di a grams,
see S90-010 O, M, and CS (Quantum
™
panel) or S70-200
OM (Plus pan el).
It is most important that these units be properly applied to an
adequately controlled refrigeration system. Your authori zed
Frick representative should be con sulted for expert guid ance
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 properly de-
signed and installed system. The Engi neering plans, piping
layouts, etc. must be detailed in accor dance with the best
practices and local codes, such as those outlined in ASHRAE
literature.
A refrigeration compressor is a VAPOR PUMP. To be cer tain
that it is not being subjected to liquid refriger ant carryover it
is necessary that refriger ant controls are carefully se lect ed
and in good operating condition; the piping is properly sized
and traps, if necessary, are correct ly arranged; the suction
line has an accumulator or slugging protec tion; that load
surg es are known and provisions made for control; op er at ing
cycles and de frost ing periods are reasonable; and that high
side condensers are sized within system and com pres sor
design limits.
It is recommended that the entering vapor temperature to the
compressor be superheated to 10°F above the refriger ant
saturation temperature. This assures 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 Pub.
E70-200 SED.
