a) Start the motor briefly (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate clockwise.
The suction pipe must not be connected
when starting up like this.
NOTICE
Incorrect direction of rotation
Running the machine in reverse for a long time may
cause damage to the blades which may lead to the
blades breaking. Use a phase sequence indicator
to check the direction of rotation
(anti-clockwise
