lecular thickness on the packed good and by its electro-chemical prop-
erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.
●
Wrap the vacuum pump in VCI film
●
Store the vacuum pump
–
if possible in original packing,
–
indoors,
–
dry,
–
dust free and
–
vibration free.
For commissioning after conservation:
●
Make sure that all remains of adhesive tape are removed from the
ports
●
Commission the vacuum pump as described in the chapter Installa-
tion and Commissioning (

Installation and
Commissioning
Installation Prerequisites
CAUTION
_a
In case of non-compliance with the installation prerequisites, partic-
ularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and adjoining
plant components!
Risk of injury!
The installation prerequisites must be complied with.
Mounting Position and Space
●
Make sure that the following ambient conditions will be complied
with:
–
ambient temperature: see “Oil”
If the vacuum pump is installed in a colder environment than al-
lowed with the oil used:
◆
Fit the vacuum pump with a temperature switch and control
the vacuum pump such that it will start automatically when
the oil sump temperature falls below the allowed temperature
–
ambient pressure: atmospheric
●
Make sure that the environmental conditions comply with the pro-
tection class of the drive motor (according to the nameplate)
●
Make sure that the vacuum pump can neither inadvertently nor in-
tentionally be stepped on and cannot be used as a support for
heavy objects
●
Make sure that the vacuum pump cannot be hit by falling objects
●
Make sure that the vacuum pump will be placed or mounted hori-
zontally
●
Make sure that the base for placement / mounting base is even
●
Make sure that in order to warrant a sufficient cooling there will be
a clearance of minimum 0.1 m between the vacuum pump and
nearby walls
●
Make sure that no heat sensitive parts (plastics, wood, cardboard,
paper, electronics) will touch the surface of the vacuum pump
●
Make sure that the installation space or location is vented such
that a sufficient cooling of the vacuum pump is warranted
In case the vacuum pump is used to convey potentially explosive
gases/gas mixtures:
◆
Make sure that the installation space or location is vented such
that operation of the safety valve will not cause an impermissi-
ble accumulation of potentially explosive atmosphere in the
environment of the vacuum pump
CAUTION
_ac
During operation the surface of the vacuum pump may reach tem-
peratures of more than 70 °C.
Risk of burns!
●
Make sure that the vacuum pump will not be touched inadver-
tently during operation, provide a guard if appropriate
●
Make sure that the sight glass (p) will remain easily accessible
If the oil change is meant to be performed on location:
◆
Make sure that the drain port (q) and the filling port (g, o) will
remain easily accessible
●
Make sure that enough space will remain for the removal and the
reinsertion of the exhaust filter
Suction Connection
CAUTION
_a
Intruding foreign objects or liquids can destroy the vacuum pump.
In case the inlet gas can contain dust or other foreign solid particles:
◆
Make sure that a suitable filter (5 micron or less) is installed
upstream the vacuum pump
In case the vacuum pump is used to convey potentially explosive
gases/gas mixtures:
◆
Make sure that the filter is sufficiently qualified for use in po-
tentially explosive atmosphere (electrically conductive, with
equipotential bonding etc.; also for non-combustible dusts!)
●
Make sure that the suction line fits to the suction connection (f) of
the vacuum pump
●
Make sure that the pipe will cause no stress on the vacuum pump’s
connection, if necessary use an expansion joint
●
Make sure that the line size of the suction line over the entire
length is at least as large as the suction connection (f) of the
vacuum pump
In case of very long suction lines it is prudent to use larger line sizes in
order to avoid a loss of efficiency. Seek advice from your Busch
representative!
If two or more vacuum pumps work on the same suction line, if the
volume of the vacuum system is large enough to suck back oil or if the
vacuum shall be maintained after switching off the vacuum pump:
◆
Provide a manual or automatic operated valve (= non-return
valve) in the suction line
(the standard non-return valve that is installed inside the suction con-
nection is not meant to be used for this purpose!)
If the vacuum pump is planned to be used for the suction of gas that
contains limited quantities of condensable vapour:
◆
Provide a shut-off valve, a drip-leg and a drain cock in the suc-
tion line, so that condensates can be drained from the suction
line
●
Make sure that the suction line does not contain foreign objects,
e.g. welding scales
Gas Discharge
The discharged gas must flow without obstruction. It is not permitted
to shut off or throttle the discharge line or to use it as a pressurised
air source.
