Page 5: Important Safety Information
The lifting eyes of the RUVAC must never be used to lift any pump combinations (Roots pump + backing pump). Exceptions are allowed only after approval by Leybold. Use a crane to secure the pump at the lifting eyes provided until a firm link has been established with the backing pump or a corresponding fixture. -
Page 6: Electrical Hazards
The pumps must only be operated at the allowed speeds. In particular when using frequency converters not approved by Leybold you must ensure an effective protection against overspeeding. -
Page 7: Thermal Hazards
Since not all application related hazards for vacuum systems can be described in detail in these Operating Instructions, Leybold has availa- ble a separate document (Safety Booklet) in which the hazards and general safety concepts for design, operation and maintenance of vac- uum systems are explained. - Page 8 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.

Page 9: Ignition Risk
All relevant safety standards and regulations must be observed. The standard version of the RUVAC is not suited for operation in explosion hazard areas. Contact us before planning to use the pump under such circumstances. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 10: Noise Hazard
The pump is not suited for applications that produce abrasive or adhe- sive substances or condensable vapours which leave adhesive or high viscosity deposits. Please contact Leybold in order to select proper separators, for example. Do not allow the ingestion of any objects (screws, welding beads, nuts, washers, pieces of wire, etc.) through the intake port of the... - Page 11 The location of the RUVAC should be such that all controls are easily accessible. In order to ensure an adequate oil supply, the location at which the pump (including its accessories) is operated should be such that angles over > 5° from the vertical are avoided.

Page 18: Transport And Storing
When the pump is removed from the shipping container it has to be secured with suitable lifting equipment until it is safely joined to a vacuum flange or a rack that is stable enough to support the weight of the pump. GA03122_002_C0 - 10/2016 - © Leybold... - Page 19 Connect the pump to oper- ate it briefly and then decommission it as described in the following sections. Refer to the frequency converter Operating Instructions when a frequency converter was longer than 2 years on stock. GA03122_002_C0 - 10/2016 - © Leybold...

Moreover, the pump attains its thermal operating limit faster. Secure the pump. Four bores in the bottom of the pump casing (M8) are pro- vided for this purpose. GA03122_002_C0 - 10/2016 - © Leybold... -

Even with clean vacuum processes, contaminants from the system may enter upon initial start-up. Depending on the operating conditions, the inlet screen may reduce the pumping speed of the pump. GA03122_002_C0 - 10/2016 - © Leybold... -

Page 23: Non-Conforming Use
When stored in a humid atmosphere corrosion can occur. Conversions, manipulations and maintenance work by persons not author- ■ ised by Leybold. The non-conforming utilisation of pump and accessories may result in WARNING severe injury or damage to the components. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 24: Connecting The Cooling Water
When connecting the cooling water by way of a “parallel connection” the NOTICE supply and return lines must not be confused. Ensure that the cooling water lines are leak tight. Water leaks can damage the electronics of the pump. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 25: Water Quality
If there is the danger of frost, you may use a water glycol mixture of up to 30 %. DS water (softened or fully desalinated water) can be used for cooling the system, if the pH value corresponds to the range indicated above. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 26: Electrical Connection
The RUVAC is suitable for operation in industrial applications only. It is not suitable for operation with mains supplies of residential areas since it could cause radio frequency interference. The connection voltage must agree with the voltage stated on the name- plate.

- Page 28 The RUVAC WH 700 must be integrated in the system control arrangement so that the pump can not run-up automatically after it has been shut down by the temperature switches in the motor. This applies equally to emergency shut-down arrangements.
- Page 29 In order to protect the pump, current limits in the frequency converter as a function of the frequency must be taken into account. See diagram for 200 V and 400 V FC motor (Section 1.3, Technical Data). GA03122_002_C0 - 10/2016 - © Leybold...

For this, evacuate the vacuum system down to a pressure below 20 mbar with the aid of the backing pump. Then switch on the RUVAC briefly; now the pressure must drop. If the pressure increases or remains constant, the RUVAC is turning in the wrong direction. GA03122_002_C0 - 10/2016 - © Leybold... -

Hot surfaces, risk of suffering burns. CAUTION Notice safety information 0.3. Never open the oil-fill or oil-drain plugs in the presence of a vacuum or while the pump is running. There is the danger that oil may squirt out. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 36: Operation With External Frequency Converter
In case a chamber pumpdown from pressures above cut-in pressure is need- ed, either bypass the RUVAC or shut it down and allow the impellers to slow down before starting pumpdown. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 37: Switching Off And Decommissioning
PFPE does not have a conserving effect. For RUVAC pumps with synthetic oil we recommend this protection measure. For transportation and storing of the pump, observe the information provided in Section 2. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 38: Maintenance
Advanced repair work not described here should be left to the Leybold Service. We would like to point out that Leybold offers training cour-ses on the main- tenance, repair, and troubleshooting of RUVAC pumps. Further details are available on request. -
Page 39: Changing The Lubricant
Under normal operating conditions, change the synthetic oil after every 8,000 hours of operation. Change the synthetic oil more frequently when pumping corrosive vapours or large amounts of dust or when cycling frequently from atmospheric to work- ing pressure. GA03122_002_C0 - 10/2016 - © Leybold... - Page 40 Do not exceed a fastening torque of 3 Nm. Otherwise the thread of the pump casing could get damaged. For recycling contaminated PFPE we ask you to consult us. As PFPE we rec- ommend our LVO 400. GA03122_002_C0 - 10/2016 - © Leybold...

They should move freely and without any resistance. Generally, the Roots pump does not need to be disassembled. If neces- sary, this should only be done by our after-sales service. GA03122_002_C0 - 10/2016 - © Leybold... -
Page 42: Service At Leybold
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.

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. - Page 47 GA03122_002_C0 - 10/2016 - © Leybold...
