3.7 Check the direction of rotation
WARNING
Obey the safety instructions given below. Failure to follow the instructions can
cause injury to people or damage to the pump/motor.

Only a trained and competent engineer may carry out the installation of the RUVAC WA
40000 pump. For advice contact your local customer centre.

Correct rotational direction is indicated by label on the pump and motor.

Blank the inlet or connect the RUVAC WA 40000 pump to the vacuum system before checking
the direction of pump rotation. If the instruction is not followed, there is danger of objects being
trapped in the rotating pump rotors.

Ensure that you do not come into contact with the shaft, the coupling or the drive system while
operating the pump. Failure to follow the instruction can cause injury to personnel by the
rotating components.
After connecting the drive/transmission or the electrical supply to the pump motor, check the
direction of rotation of the pump as follows:
1. Check the motor fan rotational direction to see if it's correct as label indicated. If necessary (that
is, to make it easier to see the pump drive shaft), temporarily remove any guard over the drive
coupling (If fitted).
2. Also Refer to Figure 2 watch the pump drive shaft or the coupling while starting up the pump
(refer to Section 4.2 ), then shut down the pump (refer to Section 4.3 ) after two seconds or so.
3. Check that the pump drive shaft or coupling rotated correctly in the expected direction.
4. If the direction of rotation was incorrect

Check the installation of the drive and transmission system and reconfigure as appropriate.
5. Perform the direction of rotation check from Step 1 again, to ensure that the pump now rotates in
the correct direction.
6. If guard over the drive coupling is removed (as in Step 1 above), refit the guard.
3.8 Connect the pump inlet and outlet
WARNING
Obey the safety instructions given below. Failure to follow the instructions can
cause injury to people or damage to the pump.

Only a trained and competent engineer may carry out the installation of the RUVAC WA
40000 pump. For advice contact your local customer centre.

Do not exceed the maximum vertical force limit of 1000N on the pump inlet and outlet flanges.
Failure to follow the instructions may result in leakage of process gases from the pump, or
damage to the pump.

Use a flexible connection in the pipeline from the vacuum system to the RUVAC WA 40000
pump to minimize vibration and stress in the system pipelines

If an isolation valve is fitted between the RUVAC WA 40000 pump and the backing pump,
interlock the operation of the valve with the operation of the RUVAC WA 40000 pump, so that
closure of the valve results in shutdown of the RUVAC WA 40000 pump.

Ensure the backing pump and exhaust extraction/abatement systems comply with the critical
backing pressure requirements of Section 2.2 and Section 2.3 .
