oil foaming, nuisance oil level cutouts, oil pressure loss,
gas or oil leakage and catastrophic compressor failure.
NOTE: The Frick

oil charge shipped with the unit is the
best suited lubricant for the conditions specied at the
time of purchase. If there is any doubt due to the refriger-
ant, operating pressures, or temperatures, refer to Frick
®
Oil publication 160-802 SPC for guidance.
1. Only use Frick

oil lter elements or warranty claim
may be denied.
2. Participate in a regular, periodic oil analysis program to
maintain oil and system integrity. Oil Analysis Kit part number:
333Q0001853.
MAINTENANCE SCHEDULE
This schedule should be followed to ensure troublefree operation of the compressor unit.
4. Vibration readings can be inuenced by other equip ment
operating in the vicinity or connected to the same piping as
the unit.
OIL QUALITY AND ANALYSIS
High quality refrigeration oil is necessary to ensure compres
sor longevity and reliability. Oil quality will rapidly deteriorate
in refrig eration systems containing moisture and air or other
contaminants. In order to ensure the quality of the refrigera
tion oil in the com pressor unit.
DO NOT MIX OILS of different
brands, manufacturers, or types.
Mixing of oils may cause excessive
a. Check bolts, shim packs, center inserts, keys, and all bolt torques.
b. Check and torque all terminals in the processor and starter panel per the specication posted in the enclosure.
c. Check calibration of Slide Valve, Slide Stop, pressures and temperatures. Calibration should be conducted with NIST certied devices.
d. Verify tightness of bolts on suction and discharge anges. See table below for torque requirements.
e. Vibration measurement must be carried out continuously to obtain optimum preventative control on bearings. If not continuously
controlled, then every 6 months, more frequently if levels increase.
f. Units with varible speed drives  check for excess vibration and skip frequencies anytime unit operating conditions change.
