Remarks to ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible fore-vacuum pressure or at maximum gas throughput depending
on the cooling method. The turbopump is intrinsically safe by a redundant temperature
monitoring.
●By reducing the fore-vacuum pressure or gas throughput, the turbopump can be ope-
rated at higher ambient temperatures.
●If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit reduces drive power first and switches off then, if necessary.

Installation
Installing the high
vacuum flange
Install the high vacuum flange in accordance with the instructions in the operating
manual of the turbopump.
Ensure the greatest possible cleanliness when installing any high vacuum parts. Un-
clean components prolong the pump-down time.
Observe the minimum strength of 170 N/mm2for the flange material.
Connecting the fore-
vacuum side
Extend the fore-vacuum line between turbopump and backing pump.
Connect the fore-vacuum line with small-flange components or threaded hose cou-
plings. Do not narrow the free cross section of the fore-vacuum flange!
With rigid pipe connections: Install bellows for attenuation of vibrations in the connec-
tion line.
5.8 Transportation lock
Turbo pumping stations of the HiCube Classic line are equipped with transportation lock
for the backing pumps (see label). The transportation lock consists of two opposing
knurled screws with spring suspension which fasten the backing pump's bottom plate.
Lift the carrying handle.
Loosen two retaining screws each from a side panel.
Remove the side panel:
– Lift the side panel approx. 2-3 cm from its adjustment and tilt it outwards.
– Disconnect the earthing cable from the terminal socket of the side panel.
– Remove the side panel from the pumping station.
Loosen the knurled screw of the transportation lock.
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
●An air cooling unit is integrated in the casing of the pumping station and is suitable for
ambient temperatures up to +35 °C.
●A venting valve is installed and connected to the turbopump.
Generally use water cooling if the ambient temperature is > +35 °C.
Connect additional accessories according to the operating manual of the turbopump.
Connecting a mea-
suring device The connection of a measuring gauge (e.g. Pfeiffer Vacuum ActiveLine) is possible to the
display and control unit DCU.
Lift the carrying handle.
Loosen two retaining screws each from a side panel.
Remove the side panel:
– Lift the side panel approx. 2-3 cm from its adjustment and tilt it outwards.
– Disconnect the earthing cable from the terminal socket of the side panel.
– Remove the side panel from the pumping station.
Unscrew the retral perforated plate from the casing of the pumping station (6x Allen
head screw 59).
Run the measuring cable via the measuring connection into the interior of the pumping
station.
Plug the measuring cable in the connection X3 of the DCU.
Settings are possible with the extended parameter set at the DCU.
NOTICE
Dangerous excess temperatures
Process-related high temperatures can result in impermissible excess temperatures
and thus damage to the turbopump.
Water cooling must be used when employing a casing heating or during operation
with heated vacuum chambers.
Do not introduce any additional energy into the pump (see p. 20, chap. 6.1).
