NOTE
Technical term.
In this instruction manual, we consider that the term ‘machine’ refers to the ‘vacuum
pump’.
2.1 Operating Principle
The machine works on the rotary vane principle.
The oil seals the gaps, lubricates the vanes and takes away compression heat.
Exhaust filters separate the oil from the discharged gas.

2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the
machine and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is capable of maintaining ultimate pressure, see Technical Data [►19].
The machine is a built-in pump designed for food vacuum packaging machines in the
domestic environment.
During operation oil accumulates at the bottom of the upper chamber of the oil separ-
ator, which cannot flow down into the bottom chamber, as long as the machine runs. At
the latest after 0.5hours of continuous operation, in case of high pressure difference
between suction side and pressure side after a shorter period, the machine must be shut
down for at least 5minutes, so that the oil can run down from the upper chamber of the
oil separator into the bottom chamber.
Permitted environmental conditions, see Technical Data [►19].
2.3 Start Controls
The machine comes without start controls. The control of the machine is to be provided
in the course of installation.
2.4 Standard Features
2.4.1 Motor Thermal Protection
Single-phase motors are equipped with a thermal protection switch to protect the ma-
chine against overload. Three-phase motors are not equipped with a thermal protection
switch.

NOTICE
In case the machine is already filled with oil.
Tilting a machine that is already filled with oil can cause large quantities of oil to in-
gress into the cylinder. Starting the machine with excessive quantities of oil in the
cylinder will immediately break the vanes and ruin the machine!
• Drain the oil prior to every transport or always horizontally transport the machine.
Machine weight:
see the technical data or the nameplate
• Check the machine for transport damage.
If the machine is secured to a base plate:
• Remove the machine from the base plate.
4 Storage
• Seal all apertures with adhesive tape or reuse provided caps.
If the machine is to be stored for more than 3 months:
• Wrap the machine in a corrosion inhibiting film.
• Store the machine indoors, dry, dust free and if possible in original packaging
preferably at temperatures between 0 ... 40 °C.

5.1 Installation Conditions
NOTICE
Use of the machine outside of the permitted installation conditions.
Risk of premature failure!
Loss of efficiency!
• Take care that the installation conditions are fully complied with.
~20 cm
~20 cm
~20 cm
~20 cm
• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [►19].
• Make sure that the environmental conditions comply with the protection class of the
motor and the electrical instruments.
• Make sure that the installation space or location is vented such that sufficient cooling
of the machine is provided.
• Make sure that cooling air inlets and outlets are not covered or obstructed and that
the cooling air flow is not affected adversely in any other way.
• Make sure that the oil sight glass (OSG) remains easily visible.
• Make sure that enough space remains for maintenance work.
• Make sure that the machine is placed or mounted horizontally, a maximum of 1° in
any direction is acceptable.
• Check the oil level, fill up if necessary, see Filling Oil [►9].
• Make sure that all provided covers, guards, hoods, etc. are mounted.
If the machine is installed at an altitude greater than 1000 meters above sea level:
• Contact your Busch representative, the motor should be derated or the ambient
temperature limited.

5.2 Connecting Lines / Pipes
• Remove all protective caps before installation.
• Make sure that the connection lines cause no stress on the machine‘s connection; if
necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the machine.
In case of very long connection lines it is advisable to use larger line sizes in order to
avoid a loss of efficiency. Seek advice from your Busch representative.
5.2.1 Suction Connection
NOTICE
Ingress of foreign objects or liquids.
Risk of damage to the machine!
If the inlet gas contains dust or other foreign solid particles:
• Install a suitable filter (5micron or less) upstream from the machine.
Connection size:
– G1/8
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
CAUTION
The discharge gas contains small quantities of oil.
Risk to health!
If air is discharged into rooms where persons are present:
• Make sure that sufficient ventilation is provided.
Connection size:
– Without connection. The discharged gas is released to the ambient of the machine.
Depending on the specific order, other connection dimensions may apply.
• Make sure that the discharged gas will flow without obstruction. Do not shut off or
throttle the discharge line or use it as a pressurised air source.

5.4 Electrical Connection
DANGER
Live wires.
Risk of electrical shock.
• Electrical installation work must only be executed by qualified personnel.
• Make sure that the power supply for the motor is compatible with the data on the
nameplate of the motor.
• The electrical installation must comply with applicable national and international
standards.
• Provide a lockable disconnect switch on the power line so that the machine is com-
pletely secured during maintenance tasks.
• Provide an overload protection according to EN 60204-1 for the motor.
• Make sure that the motor of the machine will not be affected by electric or electro-
magnetic disturbance from the mains; if necessary seek advice from Busch.
• Connect the protective earth conductor.
• Electrically connect the motor.
NOTICE
Incorrect connection.
Risk of damage to the motor!
• The wiring diagrams given below are typical. Check the inside of the terminal box for
motor connection instructions/diagrams.
