Air Compressor Cooler and Hydraulic Filter Installation
Caution: Do not install a shutoff valve in the heat exchanger water supply. This will result in
system overheat and failure, and void the manufacturer’s warranty.
The oil returning to the compressor is cooled by passing it through a water-cooled heat
exchanger, usually called the cooler.
Compressor Cooler Assembly
•
Hydraulic filter functions as the oil inlet. Oil outlet is the #8JIC fitting on the other end.
•
Hook up incoming water line to the wye strainer. Water outlet is just to the left of the
Wye strainer. The drain is the lower 3/8” FNPT fitting.
•
Install the cooler so that it can be drained to prevent freeze damage.
•
The cooler must be installed horizontally (COOLER CANNOT STAND ON END),
with the drain at the lowest point, and with a slight slope toward the water drain end.
•
The drain hose should be 0.500”I.D. minimum to provide proper drainage.
•
The outlet of the drain hose must be lower than the cooler's drain outlet and the drain
hose should be a continuous downward run (no goosenecks) to allow proper
drainage.
To mount the cooler on the side of a compartment, unbolt the brackets from the ends
and reattach them so the cooler can be installed with the drain at the lowest point.
