Check all air line connections and
check for compressed air leaks.
Remedy all leaks that are identified.
Slowly open the outlet valve to the ON
position. The compressor assembly starts and
runs until pressure in the entire compressed
air system stabilises. The air pumps then
gradually turn off at the switching pressure.
Complete a record for the installation of the
compressor assembly and commissioning
(see the Annexe in the User manual - Page
30)
Attention:
The controller display is located inside the
switchboard and is only accessible by
opening the switchboard door. The
switchboard door may only be opened
when the compressor is running by a
person trained and competent for such
activity.
Under normal circumstances, there is no
reason to open the switchboard doors as
the compressor is running in automatic
mode; the only reason to open the doors
is to remedy an alarm or to perform
maintenance work.
17. SWITCHING OFF AND SHUTTING DOWN THE COMPRESSOR
Use the main switch, Q10, to switch off the
compressor; the switch also functions as a
central stop button. This disconnects the
compressor from power. Vent the air tank by
disconnecting from the central compressed air
circuit and opening the outlet valve (Fig. 1) or
the air tank drain valve.
Attention:
Power terminals X0 remain energised even
when main switch Q10 is in the “O” (off)
position.

ensure
the
compressor
is
disconnected from the appliance
to ensure the person using the
appliance is not at risk and there
is no risk of any other material
damages!
Air pumps components (head,
cylinder, pressure hose, etc.) are
very hot during and shortly after
compressor operation – do not
touch these components!
The work below may only be performed by
trained personnel as follows:
BEFORE BEGINNING ANY OF THE
FOLLOWING
MAINTENANCE
WORK, SWITCH OFF THE MAIN
