altitude of location: up to 1000 m above sea level
•
Make sure that the environmental conditions comply with the
protection class of the drive motor (according to the nameplate)
•
Make sure that the vacuum pump can neither inadvertently nor
intentionally 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
horizontally
•
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
•
Make sure that the installation space or location is vented such
that even in the case of an impaired gas tightness of the
vacuum pump (e.g. due to illegal pressures at the gas
discharge, worn shaft seal rings or clogged pressure relief
lines) no impermissible accumulation of process gas in the
environment of the vacuum pump will occur. Closed cooling air
circuits are not permitted.
•
Make sure that the vacuum pump will not be touched
inadvertently during operation, provide a guard if appropriate
•
Make sure that the sight glass (f) of the synchronising gear will
remain accessible
Suction Connection
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 (included in scope of
delivery)
♦ Make sure that the filter is sufficiently ATEX-qualified
(electrically conductive, with equipotential bonding etc.;
also for non-combustible dusts!)
•
Make sure that the suction line fits to the suction
connection (m) of the vacuum pump
Version for the conveyance of explosive atmospheres consisting of a
mixture with air of flammable substances in the form of gas:
♦ Make sure that the pipe is made from electrically
conductive material and equipped with an equipotential
bonding connection (execution according to EN 60079-14
or equivalent national or local regulations)
Version for the conveyance of explosive atmospheres in the form of
a cloud of combustible dust in air:
♦ Make sure that the pipe is made from electrically
conductive material and equipped with an equipotential
bonding connection (execution according to EN 61241-14
or equivalent national or local regulations)
•
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 (m) 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!
In case the vacuum pump 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
suction line, so that condensates can be drained from the
suction line
♦ Make sure that the anti-pulsation chamber is equipped
with a condensate drain cock (n) (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
Gas Discharge
•
Make sure that the discharge line fits to the gas discharge (q)
of the vacuum pump
Version for the conveyance of explosive atmospheres consisting of a
mixture with air of flammable substances in the form of gas:
♦ Make sure that the pipe is made from electrically
conductive material and equipped with an equipotential
bonding connection (execution according to EN 60079-14
or equivalent national or local regulations)
•
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use an expansion joint
CAUTION
The vacuum pump is not absolutely gas tight
Risk of damage to health!
Make sure that the installation space or location is vented such
that in case of conveying media which are dangerous to health
no impermissible accumulation of conveyed media in the
environment of the vacuum pump will occur.
WARNING
In case the vacuum pump is intended to convey potentially
explosive gases/gas mixtures (
➔
page 3: Product
Description):
Risk of explosion in the discharge area!
The process gas/gas mixture must be disposed of such
that no potentially explosive gas mixtures can accumulate
in the discharge area.
CAUTION
Intruding foreign objects or liquids can destroy the vacuum
pump.
CAUTION
During operation the surface of the vacuum pump may reach
temperatures of more than 70 °C.
Risk of burns!
