Page 3: Important Safety Information
Always operate the pump with a properly connected protective earth con- ductor and make sure that the motor & FC connection box are closed. Use only the Leybold frequency converter for the pumps equipped with one. Lay the connecting lines so that these cannot be damaged. Protect the lines against humidity and contact with fluids. - Page 4 Liquid and solid particles or dust must not enter into the pump. Install the adequate filters, separators and/or condensers. In case of doubt consult Leybold. The intake line of the pump must never be connected to a device with over atmospheric pressure.
- Page 5 tive goggles also for protection against the oil. Some pumps use perfluoropolyether (PFPE) as lubricant. When handling PFPE you should observe the following: During thermal decomposition at temperatures over 290 °C toxic and corrosive gases are released. This is not likely to happen in a Sogevac pump.

Page 24: Transport And Storing
Transport and Storing 2 Transport and Storing 2.1 Transport and packaging ® SOGEVAC vacuum pumps pass a rigorous operating test in our factory and are packaged to avoid transport damages. Please check packaging on delivery for transport damages. The outer package can bear a shock indicator, turning red at 50 g. - Page 25 Transport and Storing Pump fixation The pumps are bolted by screws. Screws are to be removed from under the pallet using a 13 mm wrench. Pump lifting The pump is then ready to be shifted or lifted off the pallet. Due to the pump weight ONLY a suitable lifting device shall be used to lift the pump at the lifting lug (CE regulations) A lifting device is the only officially recommended way of handling the pump.

Page 29: Electrical Connections
Installation 3.3 Electrical connections Ensure that incoming power to the pump is off before wiring the motor or Warning altering the wiring. The specific wiring and instructions for installation given in the manual for the electric motor must be followed. The pump shall be adequately earthed to prevent the accumulation of static electricity. - Page 30 Installation 1 phase motors Should the pump be connected to a standard wall socket, it must be checked that a building protection rated 16 A is installed (fuse or breaker) to protect the power cable. Even if the pump is not operating, live voltage is present in the connection box ! Voltage and frequency mentioned on the pump nameplate must agree with the supply voltage.

Page 33: Operation
Operation 4 Operation 4.1 Operation To avoid overloading the motor, do not start the pump more than six times Warning within one hour. If frequent starts are needed, the pump shall run continuously and be linked to the vacuum vessel by means of a valve. In that case, regulation will be made by the valve and not by start/stop of the pump. - Page 34 Operation When vapors are pumped, the pump must not be switched off immediately Caution after completion of the process because the condensate dissolved in the pump oil may cause changes or corrosion. To prevent this, the pump must continue to operate with open gas ballast valve and closed intake port until the oil is free of condensate.

Page 39: Maintenance Work
Maintenance 5.4 Maintenance Work 5.4.A Checking the oil level The pump’s oil level during operation must always be between the middle and top edge of the oil-level glass. When necessary, switch off the pump and add the correct quantity of oil. Overfilling leads to oil losses at high intake pressures High oil consumption often indicates that exhaust filters are clogged (See 5.4.D). - Page 40 Maintenance 5.4.C Oil change Always change the oil when the pump is switched off but still at working Warning temperature. If there is a risk of the oil being polymerized by the connected process, change the oil immediately after operation of the pump. Pump in function is hot and some surfaces could reach a temperature higher than 80 °C (176 °F).

- Page 42 Maintenance 5.4.E Checking the float valve Tools required : Allen Key 6 mm If the pressure does not fall below approx. 5 mbar during pump operation, check the tightness of the float valve. Remove the exhaust filter with the exhaust flange. Remove the float valve screw and pull the float valve assembly out of the float chamber.
