 Ambient temperature: 25 °C [77 °F]  Temperature of the pumped gas at the inlet

connection: 15 °C [59 °F]

 Pressure:

– for vacuum−pump operation: 1013 mbar

[14.7 psia] at the discharge connection

– for compressor operation:

1013 mbar [14.7 psia] at the inlet connection

pump−motor unit may be considerably impaired. Provide a corresponding protective device (e.g. pressure relief valve) if necessary.

Transport and handling

3 Transport and handling

 WARNING

Tipping or falling can lead to crushing, broken bones etc.!

Sharp edges can cause cuts!

 Wear personal safety equipment (safety

gloves, safety shoes and safety helmet) during transport!

 WARNING

Danger from lifting heavy loads!

Manual handling of the pump−motor unit is only permitted within the following limits:

 max. 30 kg [max. 66 lbs] for men  max. 10 kg [max. 22 lbs] for women  max. 5 kg [max. 11 lbs] for pregnant women

For weights above the given values use suitable lifting appliances and handling equipment!

Weight of the pump−motor units: ( 11)

 WARNING

Danger from tipping or falling loads!

 Prior to transport and handling make sure

that all components are securely assembled and secure or remove all components the fasteners of which have been loosened!

 When transporting with lifting equipment,

observe the following basic rules:

– The lifting capacity of lifting equipment

and lifting gear must be at least equal to the unit’s weight. For the weight of the pump−motor units see:: ( 11)

– The pump−motor unit must be secured

so that it cannot tip or fall.

– Do not stand or walk under suspended

loads!

3.1 Transport devices

All pump−motor units with a weight of more than 30 kg are equipped with an eye bolt at the side channel housing.

The crane hook can be hooked directly into the eye bolt.

Alternatively the pump−motor units can be transported with lifting belts.

 WARNING

Danger from tipping or falling loads!

 Place the lifting belts under the side channel

housing and under the motor.

 Attach the lifting belts in such a way that the

suspending pump−motor unit is balanced and cannot slip out of the lifting belts.

3.2 Transport types

CAUTION

Pump−motor unit damage caused by improper manual handling!

 Do not carry the pump−motor unit by holding

it at the frequency inverter!

 Avoid heavy impact loads during transport.

CAUTION

Pump−motor unit damage caused by improper transport with lifting appliances!

 Do not attach the lifting appliances to the

frequency inverter!

 The eye bolt at the side channel housing

must

– be screwed tightly. – be exactly in axial direction of the

pump−motor unit. Lay shims under the eye bolt if necessary.

 Loads laterally to the ring level are not

permissible.

 Avoid heavy impact loads during transport.

Installation

4 Installation

 WARNING

Improper use of the pump−motor unit can result in serious or even fatal injuries!

Have you read the chapter "Safety instructions"? ( 5)

Otherwise you may not carry out any work with or on the pump−motor unit!

 DANGER!

Danger from missing view into area of pump−motor unit!

When operating the control elements without a view into the area of the pump−motor unit, there is a danger that the pump−motor unit will be switched on while other persons are still performing work on it. Severest injuries are possible!

Provide control elements at a location with a view of the pump−motor unit.

 DANGER!

Electrical danger!

The pump−motor unit must be installed so that the electrical equipment cannot be damaged by external influences!

In particular, the incoming cables must be routed securely, e.g. in cable ducts, in the floor etc.

 WARNING

Danger of balance damage caused by vibration!

Vibrating environments can cause balance damage!

Install the pump−motor unit on a solid foundation or on a solid mounting surface.

Check screw glands/unions for mounting the pump−motor unit on the mounting surface regularly for strength and firm seating.

 WARNING

Danger of crushing due to pump−motor unit tipping over!

Wear personal safety equipment (safety gloves and safety shoes). Handle the pump−motor unit with the appropriate care.

Install the pump−motor unit on a solid foundation or on a solid mounting surface!

Check screw glands/unions for mounting the pump−motor unit on the mounting surface regularly for strength.

 WARNING

Danger of fire from flammable substances!

The pump−motor unit must never come into contact with flammable substances.

For exact information on the temperature increase see: ( 12).

 WARNING

Danger of burns from hot surface of the pump−motor unit and from hot media!

High temperatures of up to approx. 160 °C [320 °F] can occur on the surface of the pump−motor unit.

The pump−motor unit must be installed so that accidental touch of its surface is not possible. Cover the pump−motor unit with a suitable touch protection (e.g. perforated plate cover or wire cover).

 WARNING

Danger of injuries from flying parts!

Select installation so that parts that are thrown out through the grate if the motor fan breaks cannot hit persons!

 CAUTION

Danger of tripping and falling!

Make sure the pump−motor unit does not present a danger of tripping.

Lay cables and pipes so that they cannot be reached during operation (recessed in floor, in ducts on the wall etc.).
