1.1 Instrument description
1 Introduction
1.1 Instrument description
The 709 IC Pump is a serial dual piston pump especially developed for
ion chromatography and optimized for use with Metrohm ion chromatographic instruments (e.g. 732 IC Detector and 733 IC Separation Center). The 709 IC Pump operates with minimal residual pulsation and has
an excellent flow constancy. In addition to the 2.709.0010 Standard
version with parts made of sapphire, ruby, ceramics, Kel-F, Teflon or
stainless steel, the totally metal free 2.709.0110 version is available.
All functions can be set simply at the front of the unit. The current and
entered data are indicated on the LED display. To assure optimum operational reliability, both lower and upper pressure limit values can be
set. If such a limit is reached, the pump switches itself off automatically.
An additional purge valve allows rapid removal of air from the pump
system.

1 Introduction
1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 709 IC Pump 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
Set the mains voltage and check the mains fuse and mains
connection in accordance with the instructions in section 2.6.
• Opening the 709 IC Pump
To avoid all danger of coming into contact with live components do
not open the instrument or remove any parts when the 709 IC Pump is
connected to the power supply. Always disconnect the instrument
from all voltage sources before you open it and ensure that the mains
cable is disconnected from mains connection plug 31 !
• 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 709 IC Pump, 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 safety rules
• Handling of solvents
Check the pump tubing and all input and output leads periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.

2.1 Setting up the 709 IC Pump
2 Installation
2.1 Setting up the 709 IC Pump
2.1.1 Packaging
The 709 IC Pump is supplied together with the separately packed
accessories in special packagings containing shock-absorbing foam
linings designed to provide excellent protection. The actual instrument
is packed in an evacuated polyethylene bag to prevent the ingress of
dust. Please store all these special packagings as only they assure
transport of the instruments free from damage.
2.1.2 Check
After receipt, immediately check whether the shipment is complete and
has arrived without damage (compare with delivery note and list of
accessories in section 6.2). In the case of transport damage, see
instructions in section 6.4.1 "Warranty".
2.1.3 Location
Position the 709 IC Pump in the laboratory at a location convenient for
operation, free from vibrations and protected against a corrosive atmosphere and contamination by chemicals.
To avoid disturbing temperature influences on the insulated column
compartment, the pump and eluent reservoir must be protected
against direct sunlight.
2.1.4 Arrangement of the instruments
In one-channel operation, the 709 IC Pump, 733 IC Separation Center
and 732 IC Detector are best stacked on top of one another in this order.
709 IC Pump
In two-channel operation (733.0X20 IC Separation Center), the optimum
arrangement (1, 2 or 3 towers) depends on the laboratory space available. However, the 709 IC Pumps should be set up at the very bottom
and the 732 IC Detectors at the very top.

2 Installation
2.2 Mounting the pump head
To ensure that the pump drive is not damaged during transport a black
plastic block is mounted in place of the pump head on the right side of
the 709 IC Pump front panel. This transport safeguard block has to be
removed after undoing the four screws.
To avoid any damage to the pump head, the protective block must be
remounted if the pump has to be moved any great distance.
Next, the 6.2824.040 Pump Head 18 (6.2824.040 or 6.2824.100) with integrated piston units is unpacked and fixed in place of the transport
safeguard block with the four hexagon screws 19 as shown in Fig. 2.
To ensure that the pump head is not positioned wrongly, the holes at
the rear for the clamping bolts have different depths, i.e. 1 clamping
bolt is longer than the rest. The deepest hole must naturally accommodate the longest bolt. If this is not the case, the pump will not
function properly.
The connection capillary 14 fastened to purge valve 24 is screwed onto
pump head 18 as shown in Fig. 2.
The 2.709.0110 IC Pump MF (metal-free version) should only be

2.3.3 Steel connectors
For the connection of steel capillaries, the steel connectors 6.2620.010
Ferrule and 6.2620.000 Pressure screw available as an option are
used. Proceed as follows:
1 Mount connectors

3 Tighten pressure screw
Tighten pressure screw 42 with the open-end spanner 1/4"
(6.2621.010) supplied.
2.3.4 Pulsation dampener
To protect the column material against pressure drops caused by the
injector, the use of a pulsation dampener connected between the pump
and the injection valve of the 733 IC Separation Center is recommended. The optional 6.2620.150 Pulsation dampener MF is very
well suited to this purpose (see section 6.3).
The metal-free 6.2620.150 Pulsation dampener is supplied fully assembled and has two connections for capillaries, for which the connectors
supplied or two 6.2744.010 PEEK compression fittings can be used.
The flow direction is arbitrary. The pulsation dampener is positioned in
the interior of the 733 IC Separation Center on the base below the injection valve (see 732/733 Instructions for Use).

1 Prepare Manufit housing
• Insert outlet capillary 55 with steel mesh holding end 53 into
Manufit housing 54.
• Insert the 4 steel meshes 52 provided into the steel mesh
holding end 53.
• Press the PTFE gasket 51 into the steel mesh holding end
53.
2 Prepare Manufit pressure screw
• Insert inlet capillary 48 with counterpart end 50 into Manufit
pressure screw 49.
3 Assembly
• Fit the two capillary end pieces 50 and 53 together.
• Screw Manufit pressure screw 49 and Manufit housing 54
firmly together.
To replace contaminated steel meshes, proceed in the reverse order.

2.4.1 Connection to injection valve with PEEK capillaries
For the pressure range 0…25 MPa (0…250 bar), it is recommended to
use 6.1831.010 PEEK capillaries, a 6.2620.150 Pulsation dampener
(see section 2.3.4), and a Filter unit PEEK (see section 2.3.5) to connect
the 709 IC Pump to the injection valve of the 733 IC Separation Center.
Proceed as follows:
1 Connection to 709 IC Pump
• Cut connection capillary 22 (6.1831.010 PEEK capillary) to
the required length and equip it with connectors.
• Attach connection capillary 22 to connection 23 of the 709 IC
Pump (see Fig. 2).
2 Connection of filter unit PEEK
• Attach the other end of connection capillary 22 at the connec-
tor 45 (with filter) of the filter unit 56 (see Fig. 6).
• Connect a PEEK capillary 43 cut to the required length and
equipped with connectors to the connector 47 of the filter unit
56.
3 Installation of the capillary in the IC Separation
Center
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
4 Connection of the pulsation dampener
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
5 Connection to the injection valve
• Procedure, see 732/733 Instructions for Use, section 2.6.5.
