Page 4: Safety Information
Attention: Make sure that a ground wire connection is established before the equipment is connected to mains supply! ➨ The pumping units MD 8C VARIO, MV 10C VARIO, PC 2008 VARIO, PC 2010 and PC 2012 VARIO are devices with double-pole cutoff and a symmetric capacitive circuit. - Page 5 page 5 of 51 ☞ Provide a firm level platform for the equipment and check that the system to be evacuated is mechanically stable and that all fittings are secure. Attention: Flexible elements tend to shrink when evacuated. Due to the high compression ratio of the pumps, pressure at the outlet port might be generated being higher than the max.
- Page 6 page 6 of 51 In case of overload the motor is shut down by a thermal cutout in the winding. ☞ Manual reset is necessary. Switch off the pump or isolate the equipment from mains. Wait approx. five minutes before restarting the pump. ☞...
- Page 7 page 7 of 51 ➨ Isolate equipment from mains and wait two minutes before starting mainte- nance to allow the capacitors to discharge. ☞ Ensure that the pump cannot be operated accidentally. Never operate the pump if covers or other parts of the pump are disassembled. Never operate a defec- tive or damaged pump.

The pump achieves its ultimate pumping speed and ultimate vacuum only at operating temperature and at 60 Hz (after approx. 15 min.) VACUUBRAND pumps of type MD 8C VARIO / MV 10C VARIO / PC 2008 VARIO / PC 2010 VARIO / PC 2012 VARIO are pumps for professional use at vacuum technical systems connected to low-voltage power supply systems of trade, research or industry. - Page 9 page 9 of 51 i t i c t i ) r r ) r r " ( " y l l < ) r r b i l c i f < / r r ) r r ° 0 The actual vacuum control range in your special application might be reduced due to ultimate vacuum of the pump, quantity of gas occurring etc.

Page 41: Replacing Diaphragms And Valves
page 41 of 51 Replacing diaphragms and valves All bearings are encapsulated and are filled with long-life lubricant. Under normal op- erating conditions, the pump is maintenance free. The valves and the diaphragms are wear parts. If the rated ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage. - Page 42 page 42 of 51 Disassembling the pump from the pumping unit PC 2008/2010 VARIO: ➨ Disconnect pump from controller (power supply and trip line). ➨ Detach separator from pump inlet. ☞ Avoid the release of pollutants. ➨ Observe applicable regulations when disposing of conden- sate which may be contaminated by pumped chemicals.
- Page 43 page 43 of 51 ➨ To check valves use hex key to remove four socket head screws from pump head and remove upper housing (hous- ing cover with housing cover insert), head cover, valves and O-rings. ☞ Never remove parts by using a spiky or sharp-edged tool (e.g.
