• Operating instructions 4.2 Function The diaphragm vacuum pump of the series MVP 015-2 is a two stage, dry compres- sor vacuum pump. The pumps are positive displacement pumps with a periodic change of size of the suction chamber produced by the movement of the dia- phragm.
– Voltage and frequency information given on the motor rating plate must be visible. – Keep the ventilation openings at the motor free, in order to provide sufficient cooling air. Installation The pump MVP 015-2 must be installed and operated under the following ambient conditions: conditions Installation location weather protected (indoors)
Installation Lay piping from the pump sloping downward so that no condensate can flow back into the pump; otherwise fit a condensate separator. – If an air trap is created in the system, then a device for draining condensation water must be provided at the lowest point.

Installation The mains voltage must be determined on-site each time before the pump is in- Single phase motors stalled or moved to a different location. NOTE Overvoltage! An incorrect voltage range setting can damage the motor. Disconnect the pump from the power supply. ...
Operation 6 Operation 6.1 Before switching on the pump Compare the voltage information on the rating plate with the mains voltage. Check that the exhaust connection allows free flow (max. permissible pressure 1.1 bar absolute). – Activate the shut-off valves in such a way that they open before or at the same time as the pump is started.
Operation 6.3 Pumping condensable vapours Should the process gases contain condensable gases present at high percentages, the vacuum pump must be operated with a gas ballast (i.e. with an open gas ballast valve). WARNING Reactive, explosive or otherwise dangerous mixtures! Uncontrolled gas inlet at the gas ballast valve can result in dangerous mixtures.
NOTE Service work should be carried out by qualified personal only! Pfeiffer Vacuum is not liable for any damage to the pump resulting from work carried out improperly. Take advantage of our service training programs; additional information at www.pfe- iffer-vacuum.net.
