Overhaul
CAUTION
Inappropiate maintenance work on the vacuum pump can damage
the pump.
Danger of explosion!
If requirements are not met, the vacuum pump may not be switched
on!
Should work exceed the dismantling work described in this
handbook, it may only be carried out by authorised persons.
DANGER
If the vacuum pump has pumped gases that were contaminated
with foreign bodies that are hazardous to health, the oil and
condensate are also contaminated with these foreign bodies.
These foreign bodies can penetrate into pores, openings and other
internal parts of the vacuum pump.
There is a health hazard when dismantling the vacuum pump.
There is also a danger to the environment.
Prior to shipping, the vacuum pump must imperatively be
decontaminated and the degree of contamination must be
documented in a declaration of decontamination ("Declaration of
Decontamination"), which can be downloaded from
www.buschvacuum.com.
Busch service will only accept vacuum pumps that come with a
completely filled in and legally binding signed form.
Removal from service
Temporary removal from service
Before disconnecting the intake and exhaust lines and switching off the
cooling water and nitrogen lines, make sure that the lines have
adjusted to atmospheric pressure.
Dismantling and disposal
DANGER

with foreign bodies that are hazardous to health, the oil and
condensate are also contaminated with these foreign bodies.
These foreign bodies can penetrate into pores, openings and other
internal parts of the vacuum pump.
There is a health hazard when dismantling the vacuum pump.
There is also a danger to the environment.
Protective clothing must be worn when dismantling the vacuum
pump.
Prior to shipping, the vacuum pump must imperatively be
decontaminated and the degree of contamination must be
documented in a declaration of decontamination ("Declaration of
Decontamination"), which can be downloaded from
www.buschvacuum.com.
Dispose of the used oil and condensate according to applicable
environmental protection regulations.
When the product has reached the end of its lifetime:
–
Decontaminate the vacuum pump.
CAUTION
Dismantling work must be carried out by authorised personnel.
Before work begins, the operator of the vacuum pump must fill in a
form or a “Declaration of Decontamination” that provides
information on possible dangers and appropriate measures.
If this form has not been filled in completely and signed, the
vacuum pump may not be dismantled.
–
Drain the oil.
u
Dispose of the oil according to local environmental protection
regulations.
