1 Introduction
1.1 Instrument description
The 752 Pump Unit is a 2-channel peristaltic pump which can be used
to pump two solutions simultaneously. It is particularly suitable for operating the suppressor module in the 2.733.0X30 IC Separation Center
by supplying regeneration and rinsing solutions. This application is described in detail in these Instructions for Use.
The 752 Pump Unit can either be operated manually by means of the
on/off switch for the pump or remotely controlled via the remote interface.

1 Introduction
1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 752 Pump Unit is assured
in the context of the specifications IEC 1010-1 (protection class 1, degree of protection IP40), the following points should be noted:
• Mains connection
Setting the mains voltage, checking the mains fuse and the mains
connection must be effected in accordance with the instructions in
section 2.2.
• Opening the 752 Pump Unit
When the 752 Pump Unit is connected to the power supply the instrument must neither be opened nor should parts be removed from
it, otherwise there is a danger of coming into contact with components which are live. Always disconnect the instrument from all voltage
sources before you open it and ensure that the mains cable is
disconnected from mains connection 1515 !
• Protection against static charges
Electronic components are sensitive to static charging and can be
destroyed by discharges. Before you touch any of the components
inside the 752 Pump Unit, you should earth yourself and any tools you
are using by touching an earthed object (e.g. housing of the instrument or a radiator) to eliminate any static charges which exist.
1.4.2 General precautionary rules
• Handling of solvents
Check all pump tubings and all input and output lines periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.
• Regular exchange of pump tubings
Pump tubings are consumable material and must be replaced from
time to time (see section 4.4). Suitable measures must be taken so
that any leak which might occur in the pump tubing or connections
during unattended operation will cause no damage (placing the
instrument at the bottom, collection device for any liquid which may
leak out).
