Step Action
1 Before starting, check the oil level in accordance with step 5 of this table.
2 Switch on the voltage.
3 Open air outlet valve (2).
4 Push the start button (6). The motor starts running after 25 seconds.
On compressors with a star-delta starter, the drive motor switches over from star to
delta 10 seconds after starting.
The maximum number of motor starts must be limited to 20 per hour.
It is strongly recommended to operate the compressor with a load factor of more than
10% to avoid condensate in the oil.
5 Regularly check the oil level. 10 to 15 minutes after stopping, the sight glass (SG)
should be between 1/4 and 3/4 full.
If the oil level is too low, stop the compressor, depressurise the oil system by
unscrewing oil filler plug (FC) one turn and wait a few minutes. Remove the plug and top
up the oil, until the sight glass is 3/4 full. Do not overfill. Fit and tighten plug (FC).
6 In automatic operation, the regulator is automatically controlling the compressor, i.e.
loading, unloading, stopping of the motors and restarting.
7 Regularly check the working pressure and the dew point (Full-Feature units).
8 Regularly check that condensate is drained (Da) during operation.
