OIL LEVEL
A visual check is sufficient to verify the oil level. Two
sight glasses are part of the oil separator and should be
used to determine the proper operating oil level.
The upper sight glass should have liquid oil visible in the
sight glass with the chiller off and the oil at 105ºF (40ºC)
and 115ºF (46ºC). When the chiller is in operation, the
oil level may be different from the standby condition,
due to the turbulence created by the discharge gas in
the oil separator. See Figure 25.
OIL FILTER
A single oil filter is provided as standard equipment and
dual oil filter arrangements are available as optional
equipment. The oil filter(s) are a replaceable 3 micron
cartridge type oil filter. Use only York approved oil filter
elements. See Figure 17.
The oil filter element should be changed after the first
200 hours of operation and then as necessary thereafter.
Change the oil filter element before the differential
pressure reaches 20 psid.
The York control panel will automatically display the
message “DIRTY OIL FILTER” when the differential

The York control panel will automatically display the
message “DIRTY OIL FILTER” when the differential
pressure reaches 20 psid across the oil filter. A safety
shutdown will be initiated if the oil pressure differential
pressure reaches 25 psid. The control panel will display
the message “CLOGGED OIL FILTER
