Troubleshooting
11.5 Replacing the Vacuum Pump
When the vacuum pump needs to be replaced, the following steps have to be carried out
in sequential order:
1. Switch the BMPC/2 to Monitor Only Mode, so that an alarm is not activated during
the service work.
2. Switch the BMPC/2 to Manual Pump Mode. Use the intact pumps and the associ-
ated valve to pump to the magnet.
3. Loosen the 4 locking screws on the pump cabinet a quarter turn to the left and
remove the front cover. You should now see the P1 pump on the left side and the P2
pump on the right side.
4. Loosen the two small flange screw connections that attach the evacuating hoses to
the pump.

5. Remove the flange screw connections and the associated seals.
6. Remove the.mains connection from the backside of the pump.
7. Unscrew the screws holding the pump unit using an 8 mm open-end wrench.
8. Move the locking mechanism so that the pump tray with the defective pump can be
freely moved.
WARNING
Pump surface can cause serious burns!
The surface of the pumps can be extremely hot! Contact with this surface can result
in a serious burn.

Be sure that the valve from the pump you want to exchange is closed!
