Page 8: Function
Product description 4.2 Function The UnoLine™ series pumps are oil-sealed, single stage operating rotary vane pumps with air cooling and circulatory lubrication. A vacuum safety valve in the intake flange closes the intake line automatically and prevents operating fluid back- streaming when the pump is switched off. -

Page 10: Connecting The Vacuum Side
Installation When installing the pump in a closed housing, ensure there is sufficient air cir- culation. – Sightglass and gas ballast valve must be visible and readily accessible. – Voltage and frequency information given on the motor rating plate must be visible. -
Page 11: Connecting To The Mains Power Supply
Installation 5.4 Connecting to the mains power supply Depending on the pump type, different motor versions are possible: • Three phase motor (without switch and mains cable). DANGER Voltage-bearing elements Electrical hazard when using electricity. The electrical connection can be carried out only by trained and authorised electricians. - Page 12 Installation Tripping devices store the shutdown event and need to be manually switched back on again via the integrated RESET button or via the external RESET S3. Mains-ON is detected as an automatic RESET. Other approved motor temperature monitoring can be used also by the operator. Set up the connections so that the directional rotation indicated on the pump is maintained, regardless of the representations in the current flow diagram.

Page 15: Install Cooling Water Unit With Thermal Circuit Breaker (Option)
Installation 5.6 Install cooling water unit with thermal circuit breaker (option) The cooling water unit is not necessary for normal operation. For critical operation conditions the water cooling unit is possible to retrofit as an option. NOTE Damage to the pump rotor For applications with short evacuating cycles or increased ambient temperature the rotor can get blocked after switching off and restarting the motor, because of different rates at which the pump housing and the rotor cool down. -

Page 17: Switching On The Pump
Operations 6.2 Switching on the pump The pump can be switched on in any pressure range. No special precautions are necessary when pumping dry gases. In order to attain the lowest possible final pressures, the gas ballast valve should be closed. Switch on the pump with the vacuum flange closed and allow to warm up for 15 minutes. -
Page 18: Pumping Condensable Vapours
Operations NOTE The oil return only works properly if the working pressure is in the range < 600mbar 6.3 Pumping condensable vapours Should the process gases contain condensable gases present at high percentages, the rotary vane pump must be operated with a gas ballast (i.e. with an open gas ballast valve). -
Page 19: Switching Off The Pump
Operations 6.4 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 differ- ential pressure between the exhaust side and the intake side is ≥ 250 mbar, then the valve closes automatically and vents the pump when the pump is switched off. -
Page 20: Maintenance
Maintenance 7 Maintenance 7.1 Precaution 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 21 In this case please get in touch with your local Pfeiffer Vacuum Service. NOTE Service work should only be carried out by qualified personal! Pfeiffer Vacuum is not liable for any damage to the pump resulting from work carried out improperly.

Page 22: Changing The Operating Fluid
Depending on the applications, Pfeiffer Vacuum recommends determining the exact 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 23: Changing The Operating Fluid Filter
Maintenance NOTE Request safety data sheets for operating fluids and lubricants from Pfeiffer Vacuum or download them from the Internet. Dispose of operating fluid according to the local regulations. 7.3 Changing the operating fluid filter Operating fluid filter 17 should be replaced at every operating fluid change but at least once every six months. - Page 24 Maintenance Disassembling Unscrew screws 146 from separator cover 145; take care with the spring washer!
