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

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.
3. For all maintenance tasks with the ex-
ception of chapter 2.6.3, 2.6.4, 2.6.10

absorbing cover by removing the four
screws (figure 8a). Attach the panel
again on completing maintenance: com-
pressor should never be operated with
the panel removed!
When the switch-on pressure is reached, the
compressor restarts automatically.

Install the elastic connecting hose between
the ball valve (item 22) and compressed air
pipe system or compressed air cold dryer.
