Figure 37. Checking Belly-Band Crankcase Heater
Crankcase Heater Thermostat : As the detected temperature changes, the resistance across the sensor changes. Table
15 on page 65 shows how the resistance varies as the temperature changes for this sensor.
NOTE - When checking the ohms across a sensor, be aware that a sensor showing a resistance value that is not within the
range shown in table 15 on page 65, may be performing as designed. However, if a shorted or open circuit is detected, the
sensor is faulty; the sensor needs to be replaced.

Compressor Sound Cover
All units come with a soft-sided polyethylene molded outer shell compressor sound cover. The cover helps reduce any un­
wanted operating sounds from the compressor. The cover features a hook/loop closure system for ease of
installation on the compressor.

Liquid Line Filter Drier
A filter drier designed for all XC25 series model units is factory-installed in the liquid line. The filter drier is designed to remove
moisture and foreign matter, which can lead to compressor failure.
