6 / 32 0870168572_MV0310B_-0001_IM_en_MD
2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an integrated fan in the drive unit.
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 not capable of maintaining ultimate pressure.
– The minimum allowed ultimate pressure is to be read from the nameplate of
the machine.
– By means of process control and/or vacuum relief valves it must be made sure
that the minimum allowed ultimate pressure will not be underrun.
The machine is suitable for continuous operation.
In order to avoid reverse rotation after switching off, the machine is equipped with a
non-return valve (NRV).
Note: The non-return valve (NRV) is no reliable means to prevent suction and shall
not be used as a non-return valve or shut-off valve for the system.
In case the machine shall be maintained after shutdown:
• Provide an additional manual or automatic operated non-return valve in the suction
line.
Permitted environmental conditions, see Technical Data [►29].
2.3 Standard Features
2.3.1 Vacuum Relief Valve
The ultimate pressure is limited by a vacuum relief valve. The vacuum relief valve is
adjusted ex-works to the minimum permitted ultimate pressure (see nameplate).
If the machine operates with a variable-frequency drive using the pressure control
mode, the ultimate pressure is limited electronically by the variable-frequency drive
and the pressure control.
2.4 Optional Accessories
2.4.1 Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas.
The inlet filter is available with a paper or polyester cartridge.

• 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.

• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [►29].
• 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 cool-
ing 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, see Oil Level Inspection [►22].

5.2 Connecting Lines / Pipes
WARNING
Rotating Parts.
Risk of severe injury!
• Do not operate the machine without suction / discharge connection installed.
• Remove all protective covers 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
Connection size(s):
– G2
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
Connection size(s):
– R1 1/4
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.

Check oil level
The oil level should stay constant over the lifetime of the oil. If the level does fall, this
indicates a leak and the machine requires repair.

5.4 Electrical Connection
(for Variable-frequency Drive)
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 drive is compatible with the data on the
nameplate of the variable-frequency drive.
• 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.
• Make sure that the EMC-class of the machine confirms with the requirements of
your supply network system, if necessary provide further interference suppression
(EMC-Class of the machine see Technical Data [►29]).
• We recommend to use gG/gL (IEC 60269-1) (class T for UL/CSA) 25 A fuses. Make
sure that the response time is below 0.4 seconds.
In case of using a residual current protective device:
• Use an all-current sensitive residual current protective device (type B).
• Electrically connect the variable-frequency drive (VFD).
