WARNING! The operator must apply all relevant Safety precautions

Run the compressor until warm. Stop the compressor, close the air outlet valve and switch off the voltage. Wait a few minutes and depressurise by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape

Wait 5 minutes and remove the oil separator (OS). Clean the seat on the manifold. Oil the gasket of the new separator and screw it into place. Tighten firmly by hand

For compressors equipped with an Elektronikon® regulator, see section Service warning

For compressors equipped with an Elektronikon® Graphic regulator, see section Service menu;

Check coolers, clean if necessary

Remove the air filter element. Clean using an air jet and inspect. Replace damaged or heavily contaminated elements

Check the filter element of the electric cabinet (where applicable). Replace if necessary

On Full-Feature units: Check condenser of dryer and clean if necessary. Check and clean the filter;

WARNING! Always apply all relevant Safety precautions. Always drain the compressor oil at all drain points. Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties. A label, indicating the type of oil filled ex factory, is stuck on the air receiver/oil tank

If the compressor is equipped with an Energy Recovery unit, also drain the oil in the heat exchanger

Run the compressor until warm. Stop the compressor. Close the air outlet valve and switch off the voltage. Depressurize the compressor by opening the manual drain valve(s). Wait a few minutes and depressurize the air receiver/oil tank by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape

Open the filler plug (FC) and drain the oil by opening the valve at the bottom of the oil tank (OT)

Also remove the drain plug near the element outlet. Close the drain valve and fit the plugs after draining

Collect the oil and deliver it to the local collection service. Refit and tighten the drain and vent plugs after draining. Tighten the top connection of the oil cooler

Remove the oil filter (OF). Clean the seat on the manifold. Oil the gasket of the new filter and screw it into place. Tighten firmly by hand
