Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere, fre-
quent temperature changes) conserve the vacuum pump immediately.
In case of favourable ambient conditions conserve the vacuum pump if
a storage of more than 3 months is scheduled.
●
Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape
Note
: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo-
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.
●
Make sure that the integration of the vacuum pump is carried out
such that the essential safety requirements of the Machine Direc-
tive 98/37/EC are complied with (in the responsibility of the de-
signer of the machinery into which the vacuum pump is to be
incorporated;
Ú
page 14: note in the EC-Declaration of Confor-
mity)
Mounting Position and Space
●
Make sure that the environment of the vacuum pump is not po-
tentially explosive
●
Make sure that the following ambient conditions will be complied
with:
–
ambient temperature: 0 ... 40 °C
–
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 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 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
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 (e, 76) of the synchronising gear will
remain accessible
In case the synchronising gear oil change is planned to be carried out
on location:
◆
Make sure that the drain port (f, 80) and the filling port (72) of
the synchronising gear will remain easily accessible
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
●
Make sure that the suction line fits to the suction connection (g/p)
of the vacuum pump
●
Make sure that the gas will be sucked through a vacuum-tight
flexible hose or a pipe
In case of using a pipe:
◆
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use bellows
●
Make sure that the line size of the suction line over the entire
length is at least as large as the suction connection (g/p) of the
vacuum pump
In case the length of the suction line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the vacuum pump. Seek advice from your Busch representative!
In case the vacuum shall be maintained after shutdown of the vacuum
pump:
◆
Provide a manual or automatic operated valve (= non-return
valve) in the suction line
Version “Aqua”, if very humid process gases and/or adverse operating
cycles bear the risk, that condensates remain in the vacuum pump:
◆
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
◆
Provide a valve for the unthrottled suction of ambient air (am-
bient air valve) between the shut-off valve and the vacuum
pump (in order to dry the vacuum pump after process end).
◆
For non ultimate-pressure-proof vacuum pumps provide a vac-
uum relief valve (suitable for continuous operation) for the
throttled aspiration of ambient air during warming up.
◆
Make sure that the anti-pulsation chamber is equipped with a
condensate drain cock (j) (optional; if the condensate drain
cock is missing contact the Busch service)
●
Make sure that the suction line does not contain foreign objects,
e.g. welding scales
