Improper Use
The following is regarded, inter alia, as improper:
– The pumping of explosive gases.
– Operating the pumps in areas where there is a danger of
explosion.
– Operating the pumps in areas there is a danger of
radionactivity.
– The pumping of gases and vapours which attack the
materials of the pumps.
– The pumping of corrosive gases without sealing gas.
– The pumping of condensating vapours.
– Operations involving impermissibly high levels of gas
loads.
– Operations with impermissibly high fore-vacuum pressure.
– Operations with improper gas modes.
– Operations involving too high levels of heat radiation
power (see Section 9. ”Technical Data”).
– Venting with rates higher than in Section 4.6. stated.
– Operating the pump without the cover plate for the TC 750
in environments which require a protection class superior
to IP 30.
– Installation of the pumps in systems where the turbomole-
cular pumps are subjected to impact-like stress and vibra-
tions or the effect of periodically occurring forces.
– The use of other power supplies or accessories which are
not named in this manual or which have not been agreed
by the manufacturer.
– The connection to power supplies with earthing of a direct
voltage pole.
The turbomolecular pumps and flange connections must not
be used to tread on when climbing onto the system.
Improper use will cause all claims for liability and guarantees
to be forfeited.

Abbreviations on the type plate of the pump
TPH/TPU 1201
Suffix ”P
P“:
Purge gas connection for the prevention of
the ingress of aggressive gases into the
motor and bearing area
Suffix”C
C“:
Surface protection for passive protection
of the pump
2.3. Scope Of Delivery
The turbopump scope of delivery includes:
– Lubricant F3 (40 ml) with filling syringe,
– cover plate for the TC 750 to fulfilled the conditions for
protection class IP 54 (please see Section 3.8.),
– protective covering for the high vacuum flange and the
fore-vacuum flange.
The fastening parts at the high vacuum flange
are not sufficient for the attachment of the
turbopump at a recipient (please refer to
Section. 3. Installation).
