Check that condensate is discharged when pressing the test button on top of the electronic water drain.

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 of condenser fins.

• Remove dust from inside the dryer, e.g. with a vacuum cleaner.

Do not use water or solvents to clean the condenser.;
