NOTE
Illustrations
In this instruction manual the illustrations may differ from the machine appearance.
2.1 Operating Principle
The machine works on the Booster blower principle.
The two oil housings (on each side) allow the lubrication of the gears and bearings.
2.2 Application
The machine is intended for the suction of air and other dry, aggressive, toxic and non-
explosive gases.
The machine is specially designed for semiconductor applications including CVD coating,
solar, flat panel... processes. This machine is not intended for load lock application.
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 vacuum booster is used in combination with a backing pump in vacuum system.
Permitted environmental conditions, see Technical Data [►26].
NOTICE
Start the backing pump first up to the allowed inlet pressure of the vacuum booster, see
Maximum Permissible Differential Pressures [►26] or call Busch representative.
Risk of damage to the machine!
NOTICE
Chemical compatibility of the process gases with the machine component materials.
Risk of corrosion inside the compression chamber which can reduce performance and
its lifetime!
• Check if the process gases are compatible with those following materials:
- Cast iron
- Steel
- Aluminium
- Epoxy resin
- Fluoroelastomer (FKM/FPM)
• In doubt, please contact your Busch representative.

2.3 Standard Features
2.3.1 Water Cooling
The machine is driven by a water-cooled motor.
2.3.2 Resistance Thermometer (TSA)
The resistance thermometer monitors the oil temperature of the machine.
A warning is emitted when the oil temperature rises to 80°C.
The machine will eventually be stopped when the temperature thermometer (TSA)
reaches 90°C.

3 Transport
WARNING
Suspended load.
Risk of severe injury!
• Do not walk, stand or work under suspended loads.
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.
• Drain the oil prior to every transport or always horizontally transport the machine.
Machine weight:
see the technical data or the
nameplate (NP)

Storage | 4
Instruction Manual PUMA WY 8000 A_EN_en 7 / 29
• 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.
• Make sure that the cooling water has been completely removed, see Decommission-
ing [►23].
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 -20 ... 55 °C.
5 Installation
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.
• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [►26].
• Make sure to use a suitable backing pump, if necessary seek advice from your Busch
representative
• 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 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.
• Make sure that the machine is secured either from the four feet or from the discharge
flange.
• Check the oil level, see Oil Level Inspection [►17].
• 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 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 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 suction connection.
Risk of severe injury!
• Do not put hand or fingers in the 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(s):
– DN250, DIN 28404 (4 M8 screws instead of 8 screws as on standard).
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
Connection size(s):
– DN100, DIN 28404 (4 M8 screws instead of 8 screws as on standard).
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.
