Programmed service interventions
Apart from the above mentioned actions, a number of service interventions (see the table below)
are programmed in the controller. Each plan has a programmed time interval at which all service
actions belonging to that plan are to be carried out. When reaching the interval, a message will
appear on the screen indicating which service plans are to be carried out.
See section

After servicing, the intervals must be reset.

Operation
Check oil level.
Check readings on the controller display.
Check the air filter service indicator.
Check that condensate is discharged during operation of the compressor.
Drain condensate.
Check the pressure dew point temperature (on compressors with integrated
dryer).
Check coolers. Clean if necessary.
Check cooling fins of electric motor(s). Clean if necessary.
Remove the air filter element and inspect. If necessary, clean using an air jet.
Replace damaged or heavily contaminated elements.
Check the filter element of the electric cabinet. Replace if necessary.
On compressors with integrated dryer:
•
Stop the compressor, close the air outlet valve and switch off the voltage.
•
Remove any dirt from the condenser inlet with a vacuum cleaner.
•
Next, clean with an air jet in the reverse direction of the normal flow. Use low
pressure air. Keep the compressed air nozzle more than 30 cm away from
the condenser to avoid damaging the condenser fins.
•
Remove dust from inside the dryer, e.g. with a vacuum cleaner.
Do not use water or solvents to clean the condenser.
Check the condition of all hoses. Replace if necessary.
