A single oil filter is provided as standard equipment
and dual oil filter arrangements are available as option-
al equipment. The oil filter(s) are a replaceable 3 mi-
cron cartridge type oil filter. Use only YORK approved
oil filter elements.
The oil filter element should be changed after the first
200 hours of operation and then as necessary thereaf-
ter. Always replace the oil filter element and O-ring on
a yearly maintenance schedule.

frequency increases to 55 Hz to maintain
the target oil pressure, the Compressor Oil
Filter is dirty and needs to be replaced.
