Transport and packing
CAUTION
Please check out the weight of the vacuum pump before lifting it up
(see "Technical Data").
Use adequate lifting gear for this.
The vacuum pumps pass a rigorous test in the factory and are packed
carefully to avoid transport damage. Please check packing on delivery
for transport damage.
The inlet and outlet ports are sealed with plugs so that no dust can pe-
netrate during transport. The plugs must be removed before starting
the vacuum pump.
The pump can be lifted from the packing using the eye bolt (2).
Packing materials should be disposed of according to environmental
regulations.
These operating instructions are part of the consignment.
Start-up
It is essential to observe the following instructions step by step to en-
sure a safe start-up.
Start-up may only be carried out by trained specialists.
Setting-up
The vacuum pump is mounted with rubber foots (with M6-threads for
fixation).
The following operating environment must be observed:
–
Ambient temperature: 5 - 40 °C
– Ambient pressure = Atmosphere
In order to avoid overheating of the pump, an undisturbed fresh
airflow to the pump is necessary.
The vacuum pump is delivered with inlet connection in vertical position
and oulet connection in horizontal position.
Inlet and outlet connections
The inlet flange can be connected with a vacuumtight flexible hose or
pipe.
Restriction of the pipes must be avoided in order not to decrease the
displacement of the pump.The nominal diameter of the pipes has to be
at least the same as the diameter of the vacuum pump's inlet flange.
No foreign particles or liquids must enter the inlet line, as they could
damage the vacuum pump. Always connect the exhaust pipe in a man-
ner, so that no condensate can enter the pump (slope, siphon).
In order to avoid process gases flowing back into the process, we re-
commend you insert a non-return valve or a shut-off device which
must be installed at the inlet flange.

Gas ballast, Busch Art. N°: 0540 559 847
A gas ballast accessory is delivered unassembled with the pump.
A gas ballast can be installed on the pump to optimise the performance
of the pump :
– To achieve the best possible end pressure, the gas ballast should be
closed. If the pump has been used to draw condensable vapours, it

may be necessary to run it for at least an hour with an open gas
ballast, before closing it again and obtaining the best end pressure.
– In order to pump condensable vapours, the gas ballast should be
open. It will prevent the condensation of vapours in the pump
through dilution of the pumped gas and clearing the condensates
out of the pump.
The gas ballast includes a filter, and this needs to be cleaned annually
or exchanged every 2 years.
The following steps must be undertaken to install the gas ballast :
•
Stop the pump
•
Remove the plug with a 8mm Allen key
•
Screw in and tighten the accessory by hand the accessory
•
The gas ballast can be opened or closed with an 8mm Allen key.
Cooling air direction check
•
Put the palm of your hand on the cooling air openings (13) of the
cover in order to check if air is put out from the fan.
•
In case of too low or none cooling air supply, check the electrical
connection of the fan motor.
•
The cooling air opennings must be released.
Electrical connection
WARNING
Electrical installation may only be carried out by a specialist. Regu-
lations following EMV Directive 2014/30/EU, and the appropriate
EN Standards have to be applied as well as VDE/ EVU regulations
and local or national regulations. The operator of the vacuum
pump must inform the manufacturer, if electric or electromagnetic
interference from his mains is to be expected.
•
Voltage and frequency on the nameplate of the motor must match
the supply voltage.
•
The drive motor must be protected against overloads according to
VDE 0113.
•
The following steps must be considered when connecting the motor
to the mains:
¨ Lay down the pump onto its side
Remove cover of the terminal box
¨
¨ Check supply voltage and frequency
Pass the electric cable through the cable gland
¨
Connect phase and earthwires, appropriate to the voltage
¨
Close the terminal box cover
