Maintenance
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 qual-
ity of the refrigera tion oil in the com pressor unit.
WARNING
Do not mix oils of different brands, manufacturers, or
types. Mixing of oils may cause excessive oil foaming,
nuisance oil level cutouts, oil pressure loss, gas or oil
leakage and catastrophic compressor failure.
NOTICE
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 re-
frigerant, operating pressures, or temperatures, refer
to Frick Oil publication 160.802-SPC for guidance.
Only use Frick oil lter elements or warranty claim
may be denied.
1. Participate in a regular, periodic oil analysis program
to maintain oil and system integrity. Oil analysis kit part
number: 333Q0001853.
2. Oil samples for analysis should be taken after the oil
lter. A 1/4 in. purge valve is provided in the oil lter can-
ister head.

Oil sampling procedure
WARNING
Exercise extreme caution in the vicinity of operating
equipment. Skin contact with lube oil or inhalation
of vapors can cause serious injury or death, consider
gloves and eye protection.
Sample hot, active uid while the equipment is operating.
Sample after 30 min of compressor operation.
1. Unthread the oil sampling valve cap and locknut
(see Figure 46).
CAUTION
Do not unthread the valve from the lter housing or
piping or uncontrolled release of oil will result.
2. Unthread the bottle cap and carefully position under
the oil sampling valve spout. Place the spout inside the
bottle.
3. Push the oil sampling valve to open and release to
close (spring actuated, see Figure 46, inset). Fill the bottle
3/4 full.
4. Retighten bottle cap, sampling valve cap and locknut.
Please note that the locknut prevents accidental release of
oil.
5. Record all necessary sample data and identication on
forms and labels and send promptly to the lab for results.
Operating log
The use of an operating log as included in this manual (see
Table of Contents) permits thorough analysis of the opera-
tion of a refrigeration system by those responsible for its
maintenance and servicing. Continual recording of gauge
pressures, temperatures, and other pertinent information,
enables the observer and serviceman to be constantly
familiar with the operation of the system and to recognize
immediately any deviations from normal operating condi-
tions. It is recommended that readings be taken at least
every four hours.
Motor bearings
Follow the motor manufacturer’s maintenance
recommenda tions for lubrication. See Table 14 and Table
15 for WEG and Marathon.
WARNING
Make sure the motor bearings are properly lubricated
before start-up as required by the motor manuf ac turer.
