CAUTION

Only authorized personnel may carry out any dismantling on the
vacuum pump. Before work begins, the operator of the vacuum
pump must fill in a form or a “Declaration Regarding Contamination
of Vacuum Equipment and Components” that provides information
on possible dangers and appropriate measures.
If this form has not been filled in completely and signed by a
responsible person, the vacuum pump may not be dismantled.

l

Proceed to disassembly of the vacuum pump. Please make sure to
wear a personal protective equipment (PPE) prior to any
intervention on the vacuum pump. Some residue may remain
inside.

l

Proceed to decommissioning of the different parts according to the
current local and national laws

Transport

The COBRA BC vacuum pumps are tested and checked in our factory
before careful packing. Check the packaging for transport damage
when the goods arrive. The pump can withstand temperatures
between -25°C and +55°C during transport.

Transport in packed state

Packed on a pallet, the vacuum pump can be moved with a hand
forklift truck.

Transport in unpacked state

The vacuum pump is fastened to the pallet with fixing pins:

u

Unscrew the fastening nuts underneath the pallet.

CAUTION

Do not work, walk or stand under suspended loads.

CAUTION

Please check out the weight of the vacuum pump before lifting it up
(see "Technical Data").

Use adequate lifting gear for this.

NOTE:

The eyebolts are fitted more or less at equal distance from the

centre of gravity of the vacuum pump incl. drive motor. If any
accessories that could upset the balance of the vacuum pump, are
installed, or if the vacuum pump is delivered without drive motor, it is
necessary to add a belt or rope at a suitable point when lifting the
pump.

l

Attach lifting gear securely to the eyebolt or eyebolts

l

Use lifting gear with a crane hook equipped with safety latch.

l

Lift the vacuum pump

In case the vacuum pump was bolted to a pallet with fixing bolts:
Unscrew the fixing bolts in the base frame.

CAUTION

In case of a vacuum pump filled with oil, make sure that by lifting
the inclination angle of the vacuum pump do not exceed 5° from
the horizontal . In case of too high inclination (>5°), risk of oil leak
within the work area

Make sure before every transport using the appropriate lifting mean
that the inclination of the vacuum pump is less than 5°.

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

l

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

l

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 are planned.

l

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