Warning: The following readings are based on ambient temperature of 80 F (27 C) with the system in good condition. The compressor should be at operating temperature at the time of the checks. One–half hour of loaded operation is usually sufficient to reach level–out operating temperatures.

Air and Oil Discharge Temperature – Read at the gauge on the instrument panel or check with a thermometer at the discharge housing.

Compressor Oil Inlet Temperature – Install a tee at the oil filter outlet and check with a thermometer.

Oil Inlet Pressure – Check at the fitting in the line near the compressor oil inlet. With air receiver pressure at 100 psi (6.9 Bars), oil inlet pressure should be.

Oil Cooler Oil Pressure Differential (Air–Cooled Radiator) – Check differential across the oil system by measuring oil inlet pressure as described above.

Oil Cooler Temperature Differential (Air–Cooled Radiator) – The oil temperature differential depends on the temperature of the air at the oil cooler fan and cleanliness of the core faces. As ambient temperatures and core restrictions increase, the oil cooler outlet temperature will increase.

The oil inlet temperature is approximately the same as the air discharge temperature – see the gauge on the instrument panel.

The outlet oil temperature may be checked by installing a tee at the oil filter outlet.

Filter Element – The element should be serviced when inspection indicates an accumulation of dirt on the outside of the element. Clean every 100 to 500 operating hours depending on dust conditions. Inspect every few days until experience determines the proper time interval for servicing.

1. Remove the element from the filter housing.

2. Blow off excess dirt with air nozzle. Direct air blast parallel to element pleats at a slight upward angle. Do not point air blast directly at the element.

3. Elements contaminated with dry dirt only:

(a) Mix a sufficient amount of warm water and household detergent to allow the element to be fully submerged.

(b) Place the element into the cleaning solution and allow to soak for five minutes. Agitate in solution for two more minutes. Elements contaminated with oil or greasy dirt deposits:

(a) Mix a sufficient amount of the following cleaning solution to allow the element to be fully submerged. To one gallon of lukewarm water add four tablespoons of mild house hold detergent and one–half teaspoon of trisodium phosphate. Mix well.

(b) Place element into cleaning solution and allow to soak for five minutes. Agitate in solution and allow to soak for five minutes. Agitate in solution for two minutes and remove.

Warning: Do not oil this element. Do not wash in other cleaning fluids. Never operate unit without element. Never use elements that are damaged or ruptured. Never use elements that won't seal. Keep spare elements on hand to reduce downtime.
