Oil Maintenance
Replacing Oil Filter
Replace oil filter: (1) annually, (2) at
each oil change, (3) or if erratic oil
pressure is experienced during
chiller operation.
Oil Filter Replacement
Use the following procedure to
service the oil filter. Refer to Figure
34.
1. Run the oil pump for two to three
minutes to insure that the oil filter
is warmed up to the oil sump
temperature.
2. Turn the oil pump motor off.
3. Pull the “D” handle on the rotary
valve locking pin out of its detent
and rotate the valve to the
“DRAIN” position. An offset
pointer is located on top of the
valve with wrench flats to allow
turning. The spring force on the
locking pin should allow the pin to
drop into a detent at this position.
4. Allow at least 15 minutes for the oil
to drain from the filter back into
the oil sump.
5. Pull the “D” handle to unlock the
pin and rotate the valve to the
“Change Filter” position. This
isolates the filter from the unit. The
locking pin should drop into a
detent in this position.
6. Remove and replace the filter as
quickly as possible. Tighten filter
2/3 to 3/4 turn per instructions
written on the filter. Place the used
filter in a reusable container.
Follow all local, state and federal
regulations to dispose of the filter.
Pull the “D” handle to unlock the
pin and rotate the valve to the
“RUN” position. The locking pin
should drop into a detent in this
position. The chiller is now ready
for operation.
7. Purge unit.
8. Check oil pressure 18-22 psi.
