WARNING

1Introduction

1.1 Safety information

Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep them, inspect the equipment. If the equipment is damaged, notify the supplier and the carrier in writing within three days; state the item number of the product together with the order number and the supplier’s invoice number. Retain all packing material for inspection.

Do not use the equipment if it is damaged.

If the equipment is not used immediately, replace the protective covers. Store the eq uipment in suitable con ditions.

z Read and obey this manual before installing or operating the equipment. z Transport the pump at the provided handle or the recessed grip.

The following symbols appear in this document:

Introduction

Warning - refer to accompanying documentation.

Warning - Isolate equipment from mains. - risk of electric shock.

Warning - Hot surfaces.

Warning - Use protective equipment.

Use the equipment for the intended use only, i. e. for generation of vacuum.

z Prevent any part of the human body from coming in contact with the vacuum. z Obey notes on correct vacuum and electrical connections. z Make sure that the individual components are only connected, combined and operated according to their

design and as indicated in the instructions for use.

A746-02-885 Issue A

WARNING

Introduction

z If the equipment is brought from cold environment into a room for operation, allow the equipment to warm

up (pay attention to water condensation on cold surfaces).

z Make sure ventilation is adequate if pump is installed in a housing or if ambient temperature is elevated.

Obey all relevant safety requirements (regulations and guidelines) and adopt suitable safety measures.

z Provide a firm level platform for the equipment and check that the system to be evacuated is mechanically

stable and that all fittings are secure.

Note: Flexible elements tend to shrink when evacuated.

Due to the high compression ratio of the pumps, pressure at the outlet port might be generated being higher than the max. permitted pressure compatible with the mechanical stability of the system.

Obey maximum permitted pressures and pressure differences, see Section 2 Technical data. Do not operate the pump with overpressure at the inlet.

Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline cannot become blocked). If you have an exhaust-isolation valve, make sure that you cannot operate the equipment with the valve closed. Risk of bursting

Ensure that the system design does not allow the exhaust pipeline to become blocked:

z Avoid overpressure of more tha n 0.2 bar in case inert gas is connected. z The diameter of the inlet and outlet pipeline should be at the least as large as the diameter of the pump

connection pipelines.

z Adopt suitable measures in case of differences, e. g. using the equipment outdoors, installation in altitudes

of more than 1000 m above mean sea level, conductive pollution or moisture.

Pay attention to symbol “hot surfaces” on the equipment. Adopt suitable measures to prevent any danger arising from the formation of hot surfaces or electric sparks.

The pumps are not suitable to pump dangerous or explosive gases or explosive or flammable mixtures. Ensure that the materials of the wetted parts are compatible with the pumped substances, see Section 2 Technical data. Adopt suitable measures to prevent the release of dangerous, explosive, corrosive or polluting fluids. Use inert gas for gas ballast or venting if necessary. The user must take suitable precautions to prevent any formation of explosive mixtures in the expansion chamber. In case of a diaphragm crack, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Take adequate precautions to protect people from the effects of dangerous substances (chemicals, thermal decomposition products of fluoroelastomers), wear appropriate safety clothing and safety glasses. Obey applicable regulations when disposing of chemicals. Take into consideration that chemicals may be polluted.

WARNING

Pumps with dual-voltage motor: The motor is shut down by a thermal cutout in the winding.

Manual reset is necessary. Switch off the pump or isolate the equipment from mains. Wait approx. five minutes before restarting the pump.

Pumps with 24 V DC voltage: The motor is protected by a temperature sensor at the circuit board (current limitation if the temperature at the circuit board is higher than 70°C). Avoid high heat supply (e. g. due to hot process gases). Ensure sufficient air admittance if pump is installed in a housing.

Due to the residual leak rate of the equipment, there may be an exchange of gas, albeit extremely slight, between the environment and the vacuum system.

z Adopt suitable measures to prevent contamination of the pumped substances or the environment.

Ensure that in case of failure, the pump and the vacuum system turn always into a safe status.

Introduction

z In case of leaks in the manifold pumped su bstances may leak in to the environment or in the p ump housing or

the motor.

z Obey especially all notes on use and operation and on maintenance. z Failure of the pump (e. g. due to power failure) must not lead to a critical dangerous situation under any

circumstances.

Use only genuine spare parts and accessories.

z Otherwise safety and performance of the equipment as well as the electromagnetic compatibility of the

equipment might be reduced.
