Maintenance checklist
Period Operation
Daily 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).
3-monthly (1) 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.
Every 5 years or
40000 hours (2)
Replace all hoses and flexibles.
(1): More frequently when operating in a dusty atmosphere
(2): Whichever comes first
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.
