Installation
5.1
Set-up
When installing the pump, observe the following conditions:
●
the ambient conditions specified for the range of application
●
When using a casing heating and a water cooling unit the temperature of the connect-
ed flange of the vacuum chamber must not exceed 120 °C.
●
The pump may be fastened to the floor only after consultation with Pfeiffer Vacuum.
●
It is not allowed to operate the device in systems where impact-like stresses and vi-
brations or periodically forces occur.
5.2
Preparatory work
Ensure sufficient cooling for the turbopump.
Where magnetic fields > 6 mT are involved, a suitable shielding must be used. Check
installation location and consult Pfeiffer Vacuum if needed!
The maximum permissible rotor temperature for the turbopump is 90 °C. If high tem-
peratures arise for process reasons, the radiated heat input must not exceed 4.2 W.
Install suitable screening sheets, if necessary (design information on request).
5.3
Assembly
●
Ensure the greatest possible cleanliness when installing any high vacuum parts. Un-
clean components prolong the pump-down time.
●
All flange components must be grease-free, dust-free and dry at installation.
●
The operating fluid reservoir is already installed and filled for the turbopump HiPace
800 P.
Earthquake safety
An earthquake can result in contact with the safety bearings. All forces occuring hereby
are safely absorbed by the properly installed flange connections.
The vacuum chamber must be secured by the customer against shifting and tipping.
WARNING
Risk of the turbopump being torn-off
In case of sudden blocking of the rotor, torques of up to 4200 Nm can occur, which can
lead with incorrect attachment to tearing the turbopump off. The energy released there-
by can hurl the entire pump or fragments from their inside around the area. This can
cause severest injuries (possibly resulting in death) and large property damage.
Precisely follow installation instructions.
Only use Pfeiffer Vacuum original components (accessories) for installation.
Installation and operation of accessories
Pfeiffer Vacuum pumps can be equipped with a series of adapted accessories. The in-
stallation, operation and maintenance of connected devices are described in detail in
the operating instructions of the individual components.
For information on order numbers of components, see "Accessories".
Use original accessory parts only.
