Sign off on the oil filter replacement

In normal operation the thermostatic valve controls the oil temperature and prevents moisture contamination of the oil. Malfunction of this valve may result in moisture in the oil system that can damage the compressor and cause oil carry-over.

A failure of the element in the closed position will divert the lubricant from the oil cooler and result in the unit shutting down due to high temperature.

A repair kit is available for this valve to replace the wearable components. Consult the parts list for your compressor to obtain the part number for this repair kit.

DANGER: Before performing any maintenance be sure the electrical supply has been cut off, locked and tagged and that all pressure has been relieved from the compressor system.

Thermostatic Control Valve Repair (Figure 5-6)

1. Place a spill pan under the valve.

2. Remove the snap ring from the top of the valve body. The valve is spring loaded and the cap may pop up when the ring is removed.

3. Remove the cap and internal parts taking care to note the orientation of the spring, piston and element.

4. Reassemble with the renewal parts. Take care when replacing the cap not to cut the “O” ring or put undue stress on the attached piping.

Check sump oil level (fill if necessary)

Check oil scavenger line for oil flow

Check pressure operating point and controls

Drain condensate from air receiver
