Use a hoist that is equipped with a hook and safety lock.

Lift the vacuum pump.

If the pump is fastened to a pallet with fixing pins:

Unscrew the fixing pins in the rubber feet.

CAUTION

The vacuum pump may not be lifted anymore when it has been
filled with oil.

Make sure before every transport that the oil has been drained out of
the vacuum pump.

The packaging material must be disposed of in accordance with local
and national regulations.

This handbook is contained in the delivery package.

Storage

Temporary storage

Make sure that the intake and exhaust flanges are closed (put on
the protective caps included in the delivery package of the vacuum
pump).

Store the vacuum pump.

–

If possible, the vacuum pump should be stored in its original
packaging

–

indoors,

–

dry,

–

in a dust-free and

–

vibration-free room.

Removal of the pump

Before starting a vacuum pump that has been stored outside the
building for a while, the vacuum pump must be moved to a room with
ambient temperature, where it should rest for a day.

Preservation

If the vacuum pump will be exposed to unfavourable ambient
conditions (for example, aggressive environment, frequent temperature
changes), begin immediately with preservation work on the vacuum
pump.
In the case of favourable ambient conditions, perform preservation
work on the vacuum pump if a storage period of more than three
months is planned.

Drain cooling water

Make sure that all openings are hermetically sealed; use adhesive
tape to fasten loose parts (seal rings, flat seals, etc.).

Wrap the vacuum pump in a VCI film.

NOTE

: VCI is the abbreviation for “volatile corrosion inhibitor”. The

VCI molecule is an organic corrosion inhibitor in the vapour phase.
Integrated in various carriers such as film, cardboard, paper, foam,
liquid and powder, it protects the parts against corrosion as a result of
its action in the vapour phase. However, VCI packaging can attack
synthetic surfaces and surfaces of other elastomers. If in doubt, please
contact your nearest distributor. VCI packaging provides several years
of protection against corrosion, even under the harshest of conditions:
overseas shipment, extended storage before use.

Store the vacuum pump.

–

If possible, the vacuum pump should be stored in its original
packaging

–

indoors,

–

dry,

–

in a dust-free and

–

vibration-free room.

Start-up of the vacuum pump after storage:

Make sure that all protective elements, stoppers or adhesive tapes
attached before preservation have been removed.

Switch on the vacuum pump in the sequence described in the
chapter “Installation and Commissioning”.

Installation and
Commissioning

Installation prerequisites

CAUTION

In case of non-compliance with the installation prerequisites,
particularly in the case of insufficient cooling:

Risk of damage or destruction of the vacuum pump and its
components!

Risk of personal injury!

The installation prerequisites must be complied with.

Make sure that the integration of the vacuum pump in its new
environment complies with the safety regulations according to the
Machinery Directive 2006/42/EC (regarding the responsibility of
the manufacturer of the system in which the vacuum pump is to be
integrated, see information in the declaration of conformity).

WARNING

Local regulations regarding the motors and electric control
elements must be observed when installing the pump in potentially
explosive environments. Make sure before start-up that all safety
measures have been followed.

Local installation

Make sure that the environment of the vacuum pump is not
potentially explosive.

Make sure that the following ambient conditions are fulfilled:

–

ambient temperature: 0 ... 40°C (32 ... 104°F)

–

ambient pressure: atmospheric

–

humidity: max. 95%, non-condensing

Make sure that the cooling water fulfills the following
requirements:

–

temperature: 10 - 30°C
