Oil change, oil refill with recommended oil

The recommended oil used for the first compressor fill up is a mineral oil with the following properties :

THE FIRST OIL CHANGE MUST BE CARRIED OUT AFTER THE FIRST 500 HOURS OPERATION.

Using a synthetic oil for compressors is also acceptable and means less frequent oil changes: please speak to us about the compatibility and oil change methodes.

The oil change and the replacement of oil filter must be carried out when the indication is seen on the electronic controller and when the corresponding time counter reaches "0".

Drain the compressor when warm. In order to do this, stop it and make sure you disconnect the electric supply and close the compressor outlet valve. Loose the filling plug by one turn to depressurise the receiver in case of component failure. Open the bleeding valve and drain it. Do not forget to close the valve after it has been drained.

After maintenance, a reset has to be done on the counter which indicates the number of remaining hours before the next oil change see the specific notice on the electronic controller.
