7. Service 

Do make use of our service facilities

In the event that repairs are necessary a number of options
are available to you to ensure any system down time is kept to
a minimum:
– Have the pump repaired on the spot by our Pfeiffer

Vacuum Service Engineers;

– Return the pump to the manufacturer for repairs;
– Replace the pump.

Local Pfeiffer Vacuum representatives can provide full
details.

Please take into account that where Pfeiffer

Vacuum Service replacement service is
involved the standard operating parameters are
always pre-set.
If your application requires different
parameters, please modify accordingly.

The turbopump and the Electronic Drive Unit

TC 750 form a single unit and must therefore be
returned complete for repair purposes. Before
returning the unit it should be ensured that the
power supply is not the cause of the
malfunction.

Before returning:

Dismantle all accessories.

If the pump is free of harmful substances please attach a
clearly visible notice "Free of harmful substances" (both on
the unit and also on the delivery note and any accompany-
ing letters). 

"Harmful substances" are substances and preparations as
defined in the current, local, dangerous substances
regulations; in the U.S.A. as" materials in accordance with the
Code of Federal Regulations (CFR) 49 Part 173.240 Definition
and Preparation". We will carry out the decontamination and
invoice this work to you if you have not attached this note.
This also applies where the operator does not have the facili-
ties to carry out the decontamination work. 

Fill out the declaration of contamination

In every case the "Declaration of Contamination" must be
completed diligently and truthfully.

A copy of the completed declaration must accompany the
unit; any additional copies must be sent to your local Pfeif-
fer Vacuum Service Center.

Please get in touch with your local Pfeiffer Vacuum represen-
tatives if there are any questions regarding contamination.

PLEASE NOTE

CAUTION

Decontaminate units before returning or
possible disposal. Do not return any units which
are microbiologically, explosively or radioactive-
ly contaminated.

Returning contaminated units

If contaminated have to be returned for maintenance/repair,
the following instructions concerning shipping must be
followed:

Neutralise the pump by flushing with nitrogen or dry air.

Seal all openings to the air.

Seal pump or unit in suitable protective foil.

Return equipment only in suitable, rugged shipping contai-
ners and by complying with the currently valid shipping
regulations.

Repair orders are carried out according to our

general conditions of sale and supply. 

If repairs are necessary, please send the pump together with
a short damage description to your nearest Pfeiffer Vacuum
Service Center.

PLEASE NOTE
