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 (
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- 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
blower, it must rotate counter-clockwise.
6.2 Decommissioning
6.2.1 After-run
Before putting the pump out of operation for more than 2 hours or before decommissioning of the vacuum
pump, remove moisture and pollution from the pump by running the vacuum pump at
- 700 mbar (abs.)
for
at least
15 - 30 minutes
with dry air.
CAUTION
Risk of injury due to hot condensate!
If condensate is discharged manually, this can cause burns.
Ø
Do not discharge the condensate manually.
Ø
If there are any condensate drains on the machine, allow the machine to cool
down before drain off the condensate.
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.
Ø
Regularly and depending on the application, discharge the condensate from the
silencer through the condensate drain (Fig. 3/X).
Depending on the use case, we recommend letting the vacuum pump run after with purging gas.
Contact the manufacturer regarding such operating conditions.
