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.
Permitted environmental conditions, see Technical Data [►16].
3 Transport
NOTICE
If the machine has a relief valve
Risk of damage to the machine!
• Do not handle the machine by the relief valve.
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.
Fixing points
• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [►16].
• Make sure that the installation space or location is vented such that sufficient cooling
of the machine is provided.
• 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
WARNING
Unprotected connection.
Risk of severe injury!
• Do not put hand or fingers in the 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 meter - ≤5 µm – 5 x 10-6 µm ) upstream from the
machine.
Connection size:
– G1/2
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
WARNING
Unprotected connection.
Risk of severe injury!
• Do not put hand or fingers in the connection.
Connection size:
– G1/2
Depending on the specific order, other connection dimensions may apply.

5.3 Electrical Connection
DANGER
Live wires.
Risk of electrical shock.
• Electrical installation work must only be executed by qualified personnel.
• 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.
• Electrically connect the machine

NOTICE
Lubricating a dry running machine (compression chamber).
Risk of damage to the machine!
• Do not lubricate the compression chamber of the machine with oil or grease.
CAUTION
During operation the surface of the machine may reach temperatures of more than
70°C.
Risk of burns!
• Avoid contact with the machine during and directly after operation.
CAUTION
Noise of running machine.
Risk of damage to hearing!
If persons are present in the vicinity of a non noise insulated machine over extended
periods:
• Make sure that ear protection is being used.
• Make sure that the installation conditions (see Installation Conditions [►6]) are met.
• Switch on the machine.
• Make sure that the maximum permissible number of starts does not exceed 12 starts
per hour. Those starts should be spread within the hour.
• Make sure that the operating conditions comply with the Technical Data [►16].
As soon as the machine is operated under normal operating conditions:
• Measure the motor current and record it as reference for future maintenance and
troubleshooting work.

6.1 Relief Valve Adjustment
The factory setting of the relief valve is set at 600 hPa (mbar) absolute for a permanent
usage. In case of cycling one, can be adjusted down to 450 hPa (mbar) absolute.
To proceed, install the vacuum pump on a pneumatic bench with an absolute pressure
sensor, an inlet valve and, if available, a volume flow sensor set at the outlet.
• Remove the black cap.
• Unlock the relief valve position by unscrewing the small hexagon socket bolt (with hex
key 2).
• Fully open the valve (decrease the spring resistance) by a clockwise rotation. Fully
close the bench inlet valve so that fresh air comes in by the relief valve only (volume
flow sensor mentions 0 lpm).
• Adjust the relief valve position by closing the valve (increase the spring resistance) by
a counter-clockwise rotation to achieve 450 hPa (mbar) absolute +/- 5 hPa.
• Lock the relief valve position by screwing the small hexagon socket bolt.
• Reposition the black cap.
