Prior to first commissioning, observe the following:
• Ensure that cooling air can flow freely.
• Check compressor oil level (see "Service and Maintenance").
• Check all connections and retighten if necessary.
• Check if the filter cartridge is in place (see "Service and Maintenance").
• Check the V-belt tension (see "Service and Maintenance").
• Check if all filling valves are closed. Open one filling valve and hold tight manually!
Kompressor starten
1. Start the compressor by switching position 1 of phase selector switch.
2. Check turning direction - see the rotary direction arrow on the compressor block (see next
pages). If the turning direction is wrong, immediately stop the compressor by switching in
position 0 and start the compressor by switching in position 2.
3. Run the compressor for about 2 minutes.
4. Close the open filling valve carefully.
5. Run the compressor up to maximum pressure and check the function of the final pressure
safety valve. If the compressor is equipped with an automatic stop system please check the
automatic shut down at final pressure. If the final pressure switch does not shut off, switch off
the compressor by placing the switch at position 0 (see chapter "Remedying faults").
6. Check the compressor unit for leaks (see "Service and Maintenance").
7. Check the condesate drain valves:
Standard: Open the condensate drain valves carefully (see "Service and Maintenance").
Option: Automatic condensate drain:
- Fix the black condensate hoses
- Drain test - press the test button
- If correct, air escapes
8. Stop the compressor by switching in position 0.
9. Open all filling valves carefully to vent.
Warning
Wrong impeller rotation direction!
Immediately after switching the compressor on, check the rotation direction. Depending
on the place of installation, the phase sequence can influence the rotation direction.
