Connecting the Extraction Unit
•
The machine must be connected to an effective
extraction system on-site.
•
The suction nozzle has a diameter of 160 mm.
•
All parts of the extraction system, including
hoses, must be included in the earthing meas-
ure.
When flexible suction hoses are used,
they must be flame-retardant.
When the machine is switched on, the
extraction system must start
automatically.

Two signal generator lines for automatic switching of the extraction system can be connected to the terminals
03
and
04
of contactor

.
Installation only by a qualified electrician!
The air speed must be set in such a way that, with the extraction line connected and the tools stationary, an
average air speed of
-
20 m/s (1450 m³/h) for dry chips,
-
28 m/s (2050 m³/h) with moist chips (moisture 18 % or more)
is achieved at the extraction nozzles.
Required negative pressure (at 20 m/s) in Pa
Planer & Jointer 900
Thicknesser 550
If the machine is properly connected to the extraction system, it can be assumed that the wood dust assess-
ment value will be complied with (permanently and safely).

Suction Nozzles
•
The air velocity must be checked before initial commissioning and after significant changes.
•
The extraction system must be checked daily for obvious defects after initial commissioning
and monthly for effectiveness.
