YORK INTERNATIONAL
COMPRESSOR
ELECTRICAL CONTROLS
Maintenance for the compressor assembly consists of
check ing the operation of the oil return system and chang-
ing the dehydrator, checking and changing the oil, check-
ing and changing the oil fi lters, checking the op er a tion of
the oil heater, checking the operation of the oil pump, and
observing the operation of the com pres sor.
Internal wearing of compressor parts could be a se ri ous
problem caused by improper lubrication, brought about
by restricted oil lines, passages, or dirty oil fi l ters. If the
unit is shutting down on (HOT) High Oil Tem per a ture
or Low Oil Pressure (OP), change the oil fi lter element.
Examine the oil fi lter element for the pres ence of alu-
mi num particles. Aluminum gas seal rings can contact
the impeller and account for some alu mi num particles to
ac cu mu late in the oil fi lter, especially during the initial
start up and fi rst several months of op er a tion. How ev er,
if aluminum particles continue to ac cu mu late and the
same conditions continue to stop the unit operation after
a new fi lter is installed, notify the nearest YORK offi ce to
re quest the presence of a YORK Service Tech ni cian.
