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.

 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.

Type of transport Type

 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: ( 11).

 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.).

Installation

CAUTION

Danger of overheating due to hot surface of pump−motor unit!

High temperatures can occur on the surface of the pump−motor unit.

Temperature−sensitive parts, such as cables or electronic components, may not come into contact with the surface of the pump−motor unit.

CAUTION

Danger of pump−motor unit damage caused by penetration of foreign bodies!

On delivery all connection openings are closed in order to prevent the penetration of foreign bodies. Remove the seals right before the respective mounting step.

Installation sequence

The pump−motor unit is ready to connect on delivery.

CAUTION

The pump−motor unit may be damaged if it is installed and commissioned after longer storage periods without special preparation!

If the pump−motor unit was stored for a longer period prior to installation, it has to be prepared for installation: ( 41)

Carry out the following steps to install the pump−motor unit:

1 Set up the pump−motor unit and attach it. 2 Mount the muffler (supplied loose) if

necessary.

3 Mount the threaded flange or hose flange to

the muffler if necessary.

4 Connect inlet and discharge connections to

the system.

5 Establish electrical connection.

4.1 Installation

CAUTION

Pump−motor unit damage caused by incorrect mounting or use under impermissible ambient conditions!

Install and connect the pump−motor unit only according to the instructions given in this chapter.

If the pump−motor unit is to be used under differing operating conditions, the manufacturer must be consulted.

NOTE

Dimensioned drawings with detailed dimensions, including fastening dimensions, are provided by the manufacturer.

4.1.1 Important notes

Ambient conditions

The pump−motor unit is suitable for installation

 in a dusty or damp environment,  in buildings,  in the open.

– For proper installation in the open, protect

the pump−motor unit from exposure to intensive sunlight, e.g. by attaching a protective roof.

– Further special protective devices against

the effects of weathering are not required.

The motors of the units are to enclosure IP55. The insulation is tropic−proof.

Installation conditions

 Attach the pump−motor unit only to even

surfaces.

 Do not exceed the maximum permissible

vibration velocity veff = 4mm/s [0.013 ft/s].

 Installation altitude max. 1000 m amsl [3280 ft

amsl].

– When installing at an altitude of more than

1000 m [3280 ft] above sea level, first inquire with the manufacturer.
