Page 11: Connecting The Exhaust Side
Installation Connecting the exhaust side CAUTION High pressure in the exhaust line! Danger of damage to the seals and danger of the pump bursting. Install the line without shut-off valves on the exhaust side. If there is danger of a build-up of excess pressure (> 1500 hPa abs.) in the lines, ob- serve all official accident prevention safety regulations. - Page 12 Installation Three-phase motor The three-phase current motor circuit The connections U1 - L2, V1 - L1 and W1 - L3 result in a clockwise rotation of the motor shaft as seen looking towards the motor fan. Delta Connection The three coils are connected in series with the connection point connected to the mains. The voltage of each coil is the same as the mains voltage whereas the mains current is the cube root of the coil current.
- Page 13 Installation Fill up the operating fluid. Motor protection With PTC temperature sensors (3PTC) Pump motors equipped with PTC temperature sensors (3PTC) in the stator windings can be connected to a PTC resistor tripping device for protection against overload. Other ap- proved motor temperature monitoring can be used also by the operator.

Page 14: Filling Up The Operating Fluid
NOTICE Use approved operating fluids only! The use of operating fluids that have not been approved by Pfeiffer Vacuum shall result in a limited warranty. In such cases, it is not possible to guarantee that product-specific performance data will be achieved. -
Page 15: Operations Monitoring (Option)
Installation Operations monitoring (Option) For operations monitoring a pressure switch can be installed on the side of the support. In case of a malfunction, e. g. pressure drop or when the pump is at rest, the contact of the pressure switch opens. The signal can be used to control external valves. Parameter Oil pressure switch Protection category IP 55... -
Page 16: Operation
Operation Operation Before switching on the pump Check the operating fluid level in the sight glass. Compare the voltage and frequency information on the rating plate with the mains volt- age and frequency values. Check that the exhaust connection allows free flow (max. permissible pressure 1500 hPa absolute). -
Page 17: Pumping Condensable Vapours
Operation Pumping condensable vapours Should the process gases contain condensable gases, the rotary vane pump must be operated with gas ballast (i.e. with an open gas ballast valve). NOTICE Bad final vacuum and damage to the pump! Danger of condensation and corrosion due to exceeding the water vapour compatibility during operation without gas ballast or in case of insufficient supply of flushing gas. - Page 18 Operation NOTICE Flushing gas pressure higher than allowed endangers the operational reliability of the pump. The power input of the pump, the temperature and the ejection of operating fluid will in- crease. Observe the maximum permissible flushing gas pressure. ...

Page 19: Topping Up The Operating Fluid
Operation Topping up the operating fluid If the operating fluid has reached its minimum filling level, the operating fluid must be topped up. The fluid can be topped up during operation in the final vacuum. Filling up the operat- Unscrew operating fluid filler screw 330. ing fluid ... -
Page 20: Switching Off The Pump
Operation Switching off the pump The pump can be switched off in any pressure range. Rotary vane pumps have an integrated safety valve on the intake side. If the differential pressure between the exhaust side and the intake side is 250 hPa, then the valve clos- es automatically and vents the pump when the pump is switched off. -
Page 21: Maintenance
Maintenance Maintenance Precautions WARNING Danger of injury from moving parts! After power failure or motor shutdown due to overheating, the motor may restart auto- matically. Secure the motor so that it cannot be switched on while any work is being performed on the pump. - Page 22 Checklist for inspec- Certain maintenance and overhaul work should only be performed by Pfeiffer Vacuum Service (PV). Pfeiffer Vacuum will be released from all warranty and liability claims if the tion, maintenance required, below listed, intervals are exceeded or maintenance or overhaul procedures and overhaul are not performed properly.

Page 23: Changing The Operating Fluid
Depending on the applications, Pfeiffer Vacuum recommends determining the ex- act service life of the operating fluid during the first year of operation. The replacement interval may vary from the guide value specified by Pfeiffer Vacuum depending on the thermal and chemical loads, and the accumulation of suspended par- ticles and condensation in the operating fluid. - Page 24 Maintenance Screw in operating fluid drain screw 328; pay attention to O-ring. Screw in operating fluid filler screw 330. Allow pump to run for a maximum of 5 seconds with the vacuum flange open. Drain off remaining operating fluid. –...

Page 25: Changing The Kind Of Operating Fluid
Maintenance Changing the kind of operating fluid When filling up, topping up or changing the operating fluid, always use the type of oper- ating fluid indicated on the pump type plate. If, for example, amended process conditions require the use of a different operating fluid, the fluid can be changed as follows: NOTICE Changing the type of operating fluid. -
Page 26: Cleaning And Re-Setting The Silencer
Maintenance Cleaning and re-setting the silencer If the silencer is not functioning, a knocking noise becomes audible at final vacuum.
