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.

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

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.

Wrap the vacuum pump in a VCI film

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 start-up”

Installation and start-up

Necessary installation instructions

CAUTION

If the necessary installation instructions are not followed and
particularly in the case of inadequate cooling:

Risk of damage to and total destruction of the vacuum pump and its
components!

Risk of personal injury!

The necessary installation instructions must be followed.

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 ele-
ments must be observed when installing the pump in potentially
explosive environments. Make sure before start-up that all safety
measures have been followed.

Installation site and 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: atmosphere

–

Humidity range: 20 to 95%

–

Altitude: up to 1000 m

CAUTION

In case of high ambient temperature, extract the air between the
machine panel and pumps casings by connecting on ventilating
extractor to the casing vent of min. 30 m

/h.

Do not connect the ventilating extractor with any process gas
discharge.

Make sure that the cooling water fulfills the following
requirements:

–

Temperature: 10 - 25 °C

–

Overpressure: 2 - 5 bar (relative)

–

Approximate flow rate: 1 l/ min for the standard version

–

Water hardness: < 5° dGH
