Commissioning and decommissioning
6.1.1 Check the rotation direction
CAUTION
Risk of injury due to wrong direction of rotation!
Rotating backwards for a longer time can cause injuries due to drawing in and can
damage the machine.
Ø
Use a phase sequence indicator to check the direction of rotation (anti-clockwise).
Ø
Keep a distance of 1 m to outlet and inlet connections.
The drive shaft direction of rotation is shown by the arrow for the direction of rotation (Fig. 2/O, 3/O) on the
motor flange.
a) Start the motor briefly (max. two seconds) to check the direction of rotation. When looking at the motor
fan, it must rotate clockwisely.
6.1.2 After-run
CAUTION
Risk of injury due to hot condensate!
If condensate is discharged manually, this can cause burns.
Ø
Regularly drain condensate from the silencer and depending on application. Do
not do this when machine is at operating temperature.
Ø
Wear protective gloves.
NOTICE
Property damage due to formation of condensate and impurities!
Due to increased condensate formation and impurities, deposits may adhere to the
rotors and the compressor casing after switching off the machine, preventing the
start-up when restarting it. Condensate and impurities can cause damage to the
machine.
Ø
Before the decommissioning of the machine, drain off the condensate.
Before putting the pump out of operation for more than 2 hours, remove moisture and contamination from
the pump by running the vacuum pump at
50 - 100 mbar (abs.)
for at least
10 minutes
with dry air.
Depending on the use case, we recommend getting the vacuum pump overrun with purge gas.
Contact the manufacturer regarding such operating conditions.
