Maintenance
Before starting any work on the compressor:
Switch the compressor off and secure it against being switched back on.
Relieve compressor from the system pressure.
After maintenance has been performed:
Connect safety switch.
Evacuate compressor.
Cancel switch-on blockage.
Avoid entry of air into the plant!
Ester oil behaves very strongly hygroscopically. The humidity bonded in the
oil cannot be removed suffi ciently by the evacuation process. Therefore very
careful handling is required!
To guarantee optimum operating safety and life of the compressor,
we recommend
performing service and checking work at regular intervals of time:
Oil change
- In series plants produced in the factory not mandatory.
- In fi eld installations or operating in the application limit area: for the fi rst time after
100 to 200 operating hours, then approx. every 3 years or 10,000 – 12,000 operating
hours. Dispose of old oil according to the regulations, observe national regulations.
Regular checks:
Oil level,
tightness, running noise, pressures, temperatures, func-
tion of the additional equipment such as oil sump heater, pressure switches: annually.
Observe national regulations.
