NOTICE
Installing a new oil filter element when the old gasket remains on the filter
head, will cause an oil leak and can cause property damage.
4. Lubricate the new filter gasket with the same oil being used in the machine.
5. Install new filter by turning the element clockwise until gasket makes initial contact. Tighten
an additional 1/2 to 3/4 turn.
6. Start unit and allow to build up to rated pressure. Check for leaks before placing unit back
into service.
Compressor Oil Cooler
The compressor lubricating and cooling oil is cooled by means of the fin and tube-type oil
cooler, located beside the radiator. The lubricating and cooling oil, flowing internally through
the core section, is cooled by the air stream from the cooling fan flowing past the core section.
When grease, oil and dirt accumulate on the exterior surfaces of the oil cooler, its efficiency is
impaired.
Each month it is recommended that the oil cooler be cleaned by directing compressed air
which contains a nonflammable, non-caustic safety solvent through the core of the oil cooler.
This should remove the accumulation of grease, oil and dirt from the exterior surfaces of the
oil cooler core so that the entire cooling area can transmit the heat of the lubricating and
cooling oil to air stream.
In the event foreign deposits, such as sludge and lacquer, accumulate in the oil cooler to the
extent that its cooling efficiency is impaired, a resulting high discharge air temperature is likely
to occur, causing shut down of the unit. To correct this situation it will be necessary to clean it
using a cleaning compound in accordance with the manufacturer’s recommendations.
Compressor Oil
The lubricating and cooling oil must be replaced every 500 hours of operation or six (6)
months, whichever comes first. Refer to warranty section about extended warranty.
