NOTE: Compressors are equipped with an oil filter. Every 2 years of operation or whenever there is a
major service procedure performed, both the compressor oil filter and filter-drier must be changed.
* When the compressor is removed from the unit, oil level should be noted or the oil removed from the
compressor should be measured so that the same amount of oil can be added before placing the
replacement compressor in the unit.

BELT TENSION
Tension No. on TK Gauge 204-427
New Belt Field Reset
Engine/Compressor 75 ± 3 70 ± 3
Compressor/Motor Drive (Jackshaft) 72 ± 3 67 ± 3
Compressor/Evaporator Fan/Alternator 55 ± 3 50 ± 3
Alternator/Evaporator Fan 55 ± 3 50 ± 3

NOTE: These are the original factory settings. Because it is difficult to use the TK gauge 204-427 in the
field, adjust each belt to allow 1/2 inch (13 mm) deflection at the center of the longest span.
NOTE: Belts should be tensioned cold and again tensioned cold after 10 hours of unit running.
