loss, environmental
3. Check the oil level (see Chap. 2.6.4).
2.4.3 Electrical connection
• The mains voltage must match that speci-
fied on the rating plate.
• Electric protection according to technical
data.
• Install the main switch and connection ca-
ble (not included in scope of supply)!
Cable: cross section: min. 2.5 mm²; max.
cable length:10 m.
With compressors from 5.5 kW, install a
star-delta switch instead of a main switch.
2.4.4 Checking / changing the rota-
tion direction
Perform a rotation direction check at the "ex-
ternal" three-phase current source before
starting operation.
1. Connect the compressor to the mains
power supply.
2. Switch on the compressor at the ON/OFF
switch.
3. Note the rotation direction of the fan
wheel.
4. If the rotation direction does not corre-
spond to the direction of the arrow on the
belt guard grating, change the direction.
5. Switch off the compressor at the ON/OFF
switch.
6. Interrupt the power supply to the main
switch.
Have a trained and qualified electrician per-
form the following tasks:
1. Change over the phases.
2. Check the rotation direction. (see above)
3. If direction of rotation has not changed:
contact service partner.
2.5 Operation
Do not overload the compressor: do not
exceed the max. number of switching cy-
cles and the ratio of operating time to
standstill!
Prevent the vessel from emptying completely
during longer downtimes***:
Close ball valve (item 22).
2.5.1 Insert
1. Connect the compressor to the mains
power supply.
2. Switch on the compressor at the ON/OFF
