1 Safety and compliance

1.1 Denition of Warnings and Cautions

NOTICE:

Obligation to Provide Information

Read and follow these instructions carefully before installing and commissioning to

ensure optimum and safe operation right from the start.

Safe and proper operation is guaranteed when used correctly and in accordance with

the instructions contained in these operating instructions. Please read all safety

instructions in this section and the rest of this manual carefully and make sure that

these instructions are followed. The device may be operated and maintained only by

trained personnel in the proper condition and as described in the operating

instructions. Also observe local and state requirements and regulations. If you have

any questions regarding safety, operation or maintenance of the device, please

contact our nearest subsidiary.

DANGER:

Danger indicates a hazard with a high level of risk which, if not avoided, will result in

death or serious injury.

WARNING:

Warning indicates a hazard with a medium level of risk which, if not avoided, could

result in death or serious injury.

CAUTION:

Caution indicates a hazard with a low level of risk which, if not avoided, could result

in minor or moderate injury.

NOTICE:

Information about properties or instructions for an action which, if ignored, will cause

damage to the pump or the system.

We reserve the right to change the design and the stated data. The illustrations are not

binding.

Keep the instructions for future use.

Safety and compliance

2 Important Safety Information

Pressures given in bar or mbar are absolute values. If exceptionally a gauge pressure is

meant, a “g” is added (for example, bar (g)).

2.1 Mechanical Hazards

1. Avoid exposing any part of the human body to the vacuum.

2. Select a secure place for the appliance (level surface).

3. Never operate the pump without a connected intake line or without tting a blank

ange.

4. The discharge port of the pump must not be blocked or constricted. Never operate

the pump with a seal-off stopper in place blanking off the exhaust port. Operate the

pump only with a connected vacuum system to the intake ange.

5. With a closed exhaust pipe, the pump can generate up to 1.5 bar (g) overpressure

on the exhaust. The exhaust pipes should be laid out accordingly.

6. Condensates from the pump can collect inside or at the exhaust, escape and spill

onto the oor, when operating the pump without an exhaust line or during transport

with an exhaust being not blanked off. In this case there exists the risk of slipping.

7. Take note of the labelling of inlet and outlet. A mix-up can lead to dangerous build-

up of pressure in the vacuum system or in the system. After each change of the

electrical connection, check the pump's rotational direction.

8. In case of power supply outage, the vacuum system is ventilated by the pump. If

this is not wanted, install a non-return valve at the inlet.

9. After a loss of power, the pump restarts independently. If this is not wanted, install a

restart inhibitor.

10. Do not operate the pump with any of the covers removed. This may result in serious

injury.

WARNING:

When rotated in the wrong direction, the pump will generate up to 4.5bar (g) pressure

at the inlet. If a vacuum system is connected, the pressure build up can lead to

explosion of the system.

2.2 Electrical Hazards

1. Housing parts must not be removed.

2. The electrical connection must only be provided by a trained person.Obey the

national regulations in the country of use like EN 50110-1 for Europe.

3. Note the information on the IP type of protection.

DANGER:

After a mains power failure the pump will run up automatically again. This also applies

in the case of an emergency shut-down. In order to prevent the pump from running

up automatically again, the pump must be integrated within a control arrangement

such that it can only be switched on manually again after the mains power has

returned.

Important Safety Information

2.3 Thermal Hazards

CAUTION:

The surface of the pump may attain temperatures over 80 °C. There is the risk of burn

injury.

1. Before servicing and maintenance work, always leave the pump to cool down.

2.4 Hazards Caused by Materials and Substances

DANGER:

Before commissioning the pump, make sure that the media which are to be pumped

are compatible with each other so as to avoid hazardous situations. Observe the

instructions for proper and improper use of the pump in Conforming Use.

2.5 Noise Hazard

CAUTION:

The noise level of the pump during ultimate pressure operation corresponds to the

values stated in the technical data. In other operating modes and depending on the

connected vacuum system, higher values can be expected. Make sure that suitable

protection measures are taken to protect your hearing.

2.6 Risk of Damaging the Pump

1. Before starting up for the rst time, the motor circuit must be equipped with a

suitable protective motor switch. Please take note of the information in these

Operating Instructions and on the electric motor (wiring diagram).

2. Do not allow the ingestion of objects (screws, nuts, washers, pieces of wire, etc.)

through the inlet port. If required, use an inlet lter.

3. Do not use the pump for applications that produce abrasive or adhesive powders or

condensible vapors that can leave adhesive or high viscosity deposits. When

planning to pump vapors other than water vapor please contact our sales or service

department for advice.

4. This pump is suited for pumping water vapor within the specied water vapor

tolerance limits.

5. Avoid vapors that can condense into liquids when being compressed inside the

pump, if these substances exceed the vapor tolerance of the pump.

6. In the case of wet processes we recommend the installation of liquid separators

upstream and downstream of the pump as well as the use of the gas ballast.

7. The exhaust line should be laid so that it slopes down and away from the pump so

as to prevent condensate from back streaming into the pump.

8. Avoid the entry of particles and uids.

9. The air intakes of the pump and the motor must remain free.
