Page 12: 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. Observe the maximum permissible pressure of 1500 hPa (absolute), activate shut- off valves in such a way that they open before or at the same time as the pump is started. - Page 13 Place OME on the exhaust side of the pump with flange pointing downwards and fit with clamping ring (accessories), pay attention to centering ring. 10/11 Fig. 5: DUO 3 DC with operating fluid return line Locking screw Spring (inside the hose) Clamping ring...

Page 16: Operation
Operation Operation Before switching on Check the operating fluid level in the sight glass. Compare the voltage information on the rating plate with the supply voltage. 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 7.3 7.1 Fig. 8: Corrosive gas version of gas ballast valve O-ring Proportioning screw O-ring Flushing gas connection (for DN 6 mm hose) Connect flushing gas at the flushing gas connection 7.4.

Page 20: 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. Unscrew operating fluid filler screw 304. Filling up the operat- ... -
Page 21: Switching Off
Operation Switching off 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 22: 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 23 Certain maintenance and overhaul work should only be performed by Pfeiffer Vacuum Checklist for inspec- 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 24: 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 25 Maintenance 304/ 308/ Fig. 11: Draining the operating fluid Screw in operating fluid drain screw 308; pay attention to O-ring. Screw in operating fluid filler screw 304. Allow pump to run for a maximum of 5 seconds with the vacuum flange open. ...
