Installation
5.1 Set-up
The installation location is to be chosen so that components that need servicing are
freely accessible at all times. No special foundations or base are necessary for in-
stallation. The unit must not be used outdoors. Conditions are:
• The ambient conditions specified for the area of use.
• a level, vibration-free surface.
• Distance to side walls or adjacent devices: at least 50 cm.
• Distance to possible edges of tables: at least 10 cm.
• When using a casing heating and a water cooling unit the temperature of the
connected flange of the vacuum chamber must not exceed 120 °C.
• It is not allowed to operate the device in systems where impact-like stresses and
vibrations or periodically forces occur.
5.2 Preparatory work
Ensure sufficient cooling for the pumping station.
Where magnetic fields > 3 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
temperatures arise for process reasons, the radiated heat input must not exceed
3 W. Install suitable screening sheets, if necessary (design information on re-
quest).
5.3 Connecting the high vacuum side
The assembly of superstructure on the pumping station HiCube 80 Eco is in the op-
erator’s responsibility. The load capacity of the high vacuum flange is specific for
the used turbopump. The gross weight of superstructure on the pumping station
HiCube 80 Eco may
not
exceed 50 kg!
Observe barycentric shifting by using high or lateral protruding superstructure
(e.g. vacuum chamber).
Danger of tilting!
Install the high vacuum flange in accordance with the instructions in the opera-
ting manual of the turbopump.
Ensure the greatest possible cleanliness when installing any high vacuum parts.
Unclean components prolong the pump-down time.
Observe the minimum strengh of 170 N/mm
2
for the flange material.
For the installation of the flange connections the following components are avail-
able:
• The valid mounting kit of the Pfeiffer Vacuum accessories programme.
• A protective screen or splinter shield can optionally be used.
5.4 Connecting the exhaust side
CAUTION
High pressure in the exhaust line!
Danger of damage to the seals and danger of the pump bursting.
Install the line without shut-off valves on the exhaust side.
Pumpe nicht mit Überdruck am Einlass betreiben; max. zulässige Drücke und Druck-
differenzen beachten.
