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
switch (item 10) or the main switch.

2.6.1 Before each maintenance task
1. Switch off compressor at the ON/OFF
switch (item 10) (if available). Discon-
nect power supply at main switch.
2. Depressurise the whole compressor:
slowly open the ball valve condensate
drainage (item 09) and close it if no more
air escapes.
2.6.2 Cleaning the compressor
• Clean the cooling fins on the cylinder, cyl-
inder head and aftercooler using com-
pressed air.
• Clean the fan impeller cover on the motor.
When the switch-on pressure is reached, the
compressor restarts automatically.
2.5.2
Install the elastic connecting hose between
the ball valve (item 22) and compressed air
pipe system or compressed air cold dryer.
2.5.3
1. Switch on the compressor at the ON/OFF
2. Interrupt the power supply to the main
