Commissioning and decommissioning
6.1.1 Checking the rotation direction
The drive shaft direction of rotation is shown by
the rotation direction arrow (Fig. 2/O) on the mo-
tor fl ange.
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate clockwise.
NOTICE
Incorrect direction of rotation
Operating in the wrong direction of rotation leads
to damage to the machine.
Use a phase sequence indicator to check the direc-
tion of rotation (anti-clockwise rotating fi eld).
6.1.2 Post-run
For removing accrued dampness and impurities out
of the pump before non-operating of > 2 hours, let
the vacuum pump post-run at 50 - 100 mbar (abs.)
with dry air minimum 10 minutes.
CAUTION
Condensate formation and impurities
By heightened condensate formation and impurities
after shutdown of the machine deposits can adhere
to rotors as well as compressor housing and prevent
an starting when restart.
According to application we recommend, let the
vacuum pump post-run with purge gas.
Please contact the manufacturer should the pump
be used under such conditions.
