Improper oil filter maintenance will cause damage to equipment. Replace filter
element every 1000 hours of operation. More frequent replacement could be
required depending on operating conditions. A filter element left in service too
long may damage equipment.
The filter media is contained within an easily replaced, spin-on cartridge. Use the following procedure to
replace the filter. Do not disturb the piping:
1. Be sure the unit is completely off and that the oil sump is depressurized.
2. Disconnect, lockout and tagout the power supply to the compressor package.
3. Close (when provided) valve isolating compressor package from air system.
4. Unscrew the cartridge with adequate tool (e.g., strap wrench) and remove.
5. Clean (wipe) and lubricate sealing surface on filter housing with grease.
6. Lubricate o-ring seal on new element with grease.
7. Screw-new element onto filter head firmly – approximately 3/4 turns after cartridge and head make
contact.
8. Open isolation valve (when provided), restore power, then run unit to check for leaks.
OIL MIXING VALVE (Electronic)
– This device mixes cold (from oil cooler) and hot (bypassed) oil in
order to achieve a compressor discharge temperature above the saturation level of the water vapor
contained in the compressed air – thus avoiding water collection in the oil system.
