Operating Instructions and follow the information so as to ensure optimum and safe working right from the start The Leybold RUVAC WH/WHU 2500/4400/7000 has 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 through- out the Operating Instructions.

The pumps must only be operated at the permitted speeds. Especially when using frequency converters which have not been specifically approved by Leybold, you need to ensure an effec tive protection against overspeeding. Should malfunctions affect the pump, seized impellers in particular owing to hard deposits or foreign objects, the occurrence of leaks affecting the housing cannot be ruled out.
The pump must only be operated at the frequency specified for the motor. For the WH 2500 use only the Leybold frequency converter. For pumps with external frequency converter: after having connected the motor and each time after having made changes to the wiring, check the motor’s direction of rotation.
For this see Section 5.5 Service at Leybold. Leybold is not in a position to perform servicing (repairs) and waste disposal of radioactively contaminated pumps. Both needs to be ensured from the side of the user.

(derating). For operation under such conditions please consult Leybold. In order to prevent the transfer of vibrations from the RUVAC to other system components which have been connected, we recommend fit- ting of corrugated hoses respectively compensators on the intake and the discharge side.

In the case of RUVAC WH pumps equipped with a frequency converter from Leybold, the frequency converter has been set up through pre-defined parameters for the purpose of protecting the pump. The built-in pump tem- perature sensor can be connected providing additional protection against thermally overloading the pump.

1) The permissible pressure differences are dependent on various factors. Please see Section 1.3.2 for further details. 2) Higher ambient temperatures are possible with reduced operating limits (derating). Please consult Leybold for details. 3) Circuit breaker capacity for operation with frequency converter.
The RUVAC pumps are designed to be functional at altitudes up to 1000 m above sea level. Operation at higher altitudes is permissible in consider- ation of reduced operating limits (derating). Please consult Leybold in this case. Secure the pump.
Pumps intended for operation with a frequency converter must not be con- nected directly to the mains power. The external frequency converters supplied by Leybold comply with EMC guidelines when the cable between pump and frequency converter does not exceed a length of 25 meters maximum. Longer cables are possible but at the risk of possibility exceeding EMC limits.
Notice safety information 0.2. For selecting the right frequency converter for your specific application please consult Leybold first. We recommend a frequency converter similar to the one described in Sections 3.4.3 and 3.4.5. This frequency converter perfectly matches the pump. A connection diagram is depicted in fig. 3.9.

60 Hz operation of the pumps. RUVAC WH The RUVAC pumps with Leybold frequency converter are so controlled that overloading is avoided. RUVAC pumps without Leybold frequency converter need to be interlocked by means of a pressure switch so that compliance with the values stated in the table of Section 1.3.1 is ensured.
Advanced repair work not described here should be left to the Leybold service. We would like to point out that Leybold offers training courses on the mainte- nance, repair, and troubleshooting of RUVAC pumps. Further details are available on request.
Maintenance Service at Leybold If you send a pump to Leybold indicate whether the pump is free of sub- stances damaging to health or whether it is contaminated. If it is contaminated also indicate the nature of the hazard. To do so, you must use a preprinted form which we shall send to you upon request.

Waste oil from vacuum pumps must not be mixed with other substances or materials. Waste oil from vacuum pumps (Leybold oils which are based on mineral oils) which are subject to normal wear and which are contaminated due to the influence of oxygen in the air, high temperatures or mechanical wear must be disposed of through the locally available waste oil disposal system.
