Prior to first commissioning, observe the following:
Necessary steps are described on the next page.
• Ensure that cooling air can flow freely.
• Check compressor oil level with the oil dipstick (see next page).
• 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 next page).
• Check if all filling valves are closed. Open one filling valve and hold tight manually!
Start the compressor
1. Start the compressor by pushing the ON button.
2. Check turning direction - see the rotary direction arrow on the housing of the electric motor
(see next pages). If the turning direction is wrong, immediately stop the compressor by pushing
the OFF button and contact an authorised electrician.
3. Check oil pressure (if oil pressure gauge is installed).
4. Run the compressor for about 2 minutes.
5. Close the open filling valve carefully.
6. Run the compressor up to maximum pressure and check if the final pressure switch shuts off
the compressor. If the final pressure switch does not shut off, switch off the compressor with
the OFF button (see chapter "REMEDYING FAULTS").
7. Check the compressor unit for leaks (see "SERVICE AND MAINTENANCE")
8. Now check the condensate drain valves:
- Fix the black condensate hoses
- Drain test - press the test button
- If correct, air escapes
9. Stop the compressor by pushing the OFF button.
10. 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.
