    Operating Instructions. Note The Leybold SOGEVAC Neo D have been designed for safe and efficient operation when used properly and in accordance with these Operating Instructions. It is the responsibility of the user to carefully read and strictly observe all safety precautions described in this section and throughout the Operating Instructions.
  • Page 4 Liquid and solid particles or dust must not enter 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. Design the exhaust line so that no pressure higher than 1,15 bar abs.
  • Page 5 Important Safety Information 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. When handling PFPE keep it way from open fires.

    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 39 Installation The pump is designed for direct starting even under load conditions, i.e. the pump can be switched on against vacuum in the intake port. After connecting the motor and after every time you alter the wiring, check the direction of rotation. Refer to the arrow marked on the generator fan cover center and on the motor cover: During the check, the intake port should be open.
  • Page 40 Installation Frequency converter 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. The frequency converter itself is self-protecting. Voltage and frequency mentioned on the pump nameplate must agree with the supply voltage.

    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 44 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.

    Maintenance 5.4 Maintenance Work 5.4.A Checking the oil level The pump’s oil level during operation must always be in the upper quarter 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 50 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).
