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
