SECTION 8
– MAINTENANCE
It is the responsibility of the equipment owner to provide maintenance on the system.
IMPORTANT
If system failure occurs due to improper maintenance during the warranty period, YORK will not be
liable for costs incurred to return the system to satisfactory operation. The following is intended only
as a guide and covers only the unit components.
It does not cover other related system components which may or may not be furnished by YORK.
System components should be
maintained according to the individual manufacture’s
recommendations as their operation will affect the operation of the unit.
COMPRESSORS
Oil Charge
The oil used in these compressors is pale yellow in color. If one of the compressors in a refrigerant
system fails to rotate and a replacement is needed, it is strongly recommended to clean the system
and refill the oil. Examine the oil color during the process. If the oil darkens or exhibits a change in
color, this may be an indication of contaminants in the refrigerant system.
Never use the scroll compressor to pump the refrigerant system down into a vacuum. Doing so will
cause internal arcing of the compressor motor which will result in failure of compressor.
CONDENSER COILS
Dirt should not be allowed to accumulate on the con- denser coil surfaces. Cleaning should be as
often as necessary to keep coils clean.
Exercise care when cleaning the coil so that the coil fins are not damaged.
OPERATING PARAMETERS
Regular checks of the system should be performed to ensure that operating temperatures and
pressures are within limitations, and that the operating controls are set within proper limits.
Refer to the Operation, Start- Up, and Installation sections of this manual.
CONDENSER FAN MOTORS
Condenser fan motors are permanently lubricated and require no maintenance.
OVERALL UNIT INSPECTION
In addition to the checks listed on this page, periodic overall inspections of the unit should be
accomplished to ensure proper equipment operation. Items such as loose hardware, component
operation, refrigerant leaks, unusual noises, isolators, etc. should be investigated and corrected
