2.1 Operating Principle

Product Description | 2
0870168409_MV0602B_O2_A0000_IM_en 5 / 24
The machine works on the claw principle.
2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
The oxygen version is especially designed for conveying gases with an increased oxygen
content (volume content greater than 21% and up to 100%).
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 ulti-
mate 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 ulti-
mate pressure will not be underrun.
The machine is suitable for continuous operation.
Permitted environmental conditions, see Technical Data [►19].
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 ad-
justed ex-works to the minimum permitted ultimate pressure (see nameplate).
2.3.2 Temperature Transmitter
The temperature transmitter monitors the gas temperature of the machine.
The gas temperature must not exceed the permitted trip signal temperature, see Tech-
nical Data [►19].
A Trip signal must be set, see Wiring Diagram Temperature Transmitter [►11].
2.3.3 Flow Control Device
The flow control device monitors the cooling air volume flow of the machine.
The cooling air volume flow must neither exceed nor underrun the permitted monitoring
speed range, see Technical Data [►19].
A monitoring range is pre-installed, see Wiring Diagram Flow Control Device [►11].
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 polyester cartridge.

5 Installation
WARNING
Lack of oxygen regulation knowledge.
Risk of fire!
• Installation, commissioning and maintenance must only be carried out by qualified
personnel who are informed about the applicable safety regulations and trained in the
handling of oxygen.
• Accident prevention regulations or methods must imperatively be complied with.
Seek further information:
- European Industrial Gases Association “EIGA” www.eiga.eu (EIGA SAG NL 79/04).

5.1 Installation Conditions
WARNING
The machine is not absolutely gas tight.
Risk of fire!
• The installation area must be aired in such a way so as to prevent unacceptable levels
of oxygen.

• 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.
• 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.

5 | Installation
8 / 24 0870168409_MV0602B_O2_A0000_IM_en
• 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.
• Check the oil level, see Oil Level Inspection [►13].
• Make sure that all provided covers, guards, hoods, etc. are mounted.
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
Intruding 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:
– G3
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
Connection size:
– R2
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.
Unless the aspirated air is discharged to the environment right at the machine:
• Make sure that the discharge line either slopes away from the machine or provide a li-
quid separator or a siphon with a drain cock, so that no liquids can flow back into the
machine.
5.3 Filling Oil
WARNING
Fill the machine with wrong oil type.
Risk of fire!
• Only use oil approved by Busch and suitable for oxygen application, see Oil [►19].

Installation | 5
0870168409_MV0602B_O2_A0000_IM_en 9 / 24
At delivery, the machine is already filled with specific oil "Busch YLC 250 B" which is
suitable for oxygen application.
A lead seal is applied on the oil fill plug (OFP) and the oil drain plug (ODP) in order to
prevent wrong material from being filled in.
Lead seal must only be removed and applied by authorised and trained personnel, seek
advice from your Busch representative.
NOTICE
Remove lead seal without Busch approval.
Loss of Busch liability!
• Ask your Busch representative before filling or draining the oil.
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.
• Provide 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.

WARNING
Use of non-Busch genuine spare parts.
Risk of fire!
• Only use Busch spare parts approved by Busch and suitable for oxygen application.
WARNING
Machines contaminated with hazardous material.
Risk of poisoning!
Risk of infection!
If the machine is contaminated with hazardous material:
• Wear appropriate personal protective equipment.
CAUTION
Hot surface.
Risk of burns!
• Prior to any action requiring touching the machine, let the machine cool down first.
• Shut down the machine and lock against inadvertent start up.
• Vent the connected lines to atmospheric pressure.
If necessary:
• Disconnect all connections.
• Make sure to have an authorisation from Busch to perform any maintenance tasks.
7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are desired to be considered as starting values which should be
shortened or extended as appropriate. Particularly heavy duty operation, such as high
dust loads in the environment or in the process gas, other contamination or ingress of
process material, can make it necessary to shorten the maintenance intervals significant-
ly.
Every 3 months • Check the oil level, see Oil Level Inspection [►13].
Every 6 months • Clean the machine from dust and dirt.
Every 6 years • Have a major overhaul on the machine (contact
Busch).
7.2 Oil Level Inspection
• Shut down the machine.
• When the machine is stopped, wait 1 minute before checking the oil level.
