1 Safety and compliance

1.1 Denition of Warnings and Cautions

NOTICE:

For safe operation from the start, read these instructions carefully before you install or

commission the equipment and keep them safe for future use.

Read all the safety instructions in this section and the rest of this manual carefully

and make sure that you obey these instructions. The equipment must only be

operated and maintained by trained personnel in the proper condition and as

described in this instruction manual.

Obey local and state requirements and regulations. If you have any questions about

safety, operation or maintenance of the device, please contact our nearest subsidiary.

Important safety information is highlighted as warning and caution

instructions. Obey these instructions.

WARNING:

If you do not obey a warning, there is a risk of injury or death. Different symbols are

used according to the type of hazard.

CAUTION:

If you do not obey a caution, there is a risk of minor injury, damage to equipment,

related equipment or process.

NOTICE:

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

damage to the equipment.

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

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.

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.

2.2 Electrical hazards

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.

1. Housing parts must not be removed.

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

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

Europe.

300766038_002_C3 - 09/2021 - © Leybold

Important Safety Information

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

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 powder vapour sales or service department for advice.

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

water vapour tolerance limits.

5. Avoid vapour that can condense into liquids when being compressed

inside the pump, if these substances exceed the vapour 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.

Important Safety Information

3 Description

The pump is a dry-compressing vacuum pump and can evacuate containers

in the rough vacuum range.

The pump is connected to a 3-phase network on the motor terminal board

and operated directly from the mains. It is air-cooled and requires minimum

maintenance.

3.1 Supplied equipment

The pump is delivered ready for operation. Intake and exhaust anges are

covered with caps.
