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 re

sponsible person, the vacuum pump may not be dismantled.

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.

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:

Unscrew the fastening nuts underneath the pallet.

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 access

ories 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.

Attach lifting gear securely to the eyebolt or eyebolts

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

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

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 are planned.

Make sure that all openings are hermetically sealed; use adhesive

tape to fasten loose parts (seal rings, flat seals, etc.).

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.
