7.2  Work to be carried out

In order to guarantee optimum operational reliability and service life of the compressor, 

we   recommend 

carrying out servicing and inspection work at regular intervals:

 

Oil change: 

   - 

not mandatory for factory-produced series systems.

   - 

 for field installations or when operating near the application limit: for the first time after 100 
to  200  operating  hours,  then  approx.  every  3  years  or  10,000  -  12,000  operating  hours. 
Dispose of used oil according to the regulations; observe national regulations.

 

Annual checks:

  Oil  level,  leak  tightness,  running  noises,  pressures,  temperatures,  function  of 

 auxiliary devices such as oil sump heater, pressure switch.

6.8  Connection of oil level regulator

The connection "O" is provided for installing an oil level regulator. A corresponding adapter must be 
obtained from the trade.

 Switch off the compressor and secure it to prevent a restart.
 Relieve compressor of system pressure.
 Prevent air from infiltrating the system!

After maintenance has been performed:

  Connect safety switch.
  Evacuate compressor.
  Release switch lock.
