1 Introduction
1.1 Instrument description
The 782 IC Column Thermostat consists of a control unit and the «IC
Column Heater» column heating element, which is placed inside the
733 IC Separation Center or the 761 Compact IC. The separating column inserted in the column heating element is brought to the preset
temperature within a few minutes. The current and set temperature values can be read off from the control unit at any time.

1 Introduction
1.4 Safety notes
While electrical safety in the handling of the 782 IC Column Thermostat
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 must be effected in accordance with the
instructions in section 2.2.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
If the 782 IC Column Thermostat is connected to the power supply,
the instrument must not be opened nor must parts be removed from
it, otherwise there is a danger of coming into contact with components which are live. Hence, always disconnect the instrument from all
voltage sources before you open it and ensure that the mains cableis disconnected from mains connection 1212 !
• 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 782 IC Column Thermostat, 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.

2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The 762 IC Interface is supplied together with the separately packed
accessories in special packagings containing shock-absorbing foam
linings designed to provide excellent protection. The instrument itself 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 instrument free from damage.
2.1.2 Check
2.1 Setting up the instrument
After receipt, immediately check whether the shipment is complete and
has arrived without damage (compare with delivery note and list of
accessories in section 4.2). In the case of transport damage, see
instructions in section 4.4.1 "Warranty".
2.1.3 Location
Position the instrument in the laboratory at a location convenient for operation, free from vibrations and protected against a corrosive atmosphere and contamination by chemicals.
2.1.4 Arrangement of the instruments
The 782 IC Column Thermostat can be piled up together with other IC
instruments (e.g. 732, 733, 709).

2.2 Mains connection
Follow the instructions below for connecting to the power supply. If
the instrument is operated with the mains voltage set wrongly and/or
wrong mains fuse there is a danger of fire!
2.2.1 Setting the mains voltage
Before switching on the 782 IC Column Thermostat for the first time,
check that the mains voltage set on the instrument (see Fig. 3) matches
the local mains voltage. If this is not the case, you must reset the mains
voltage on the instrument as follows:
Disconnect mains cable
1
Disconnect mains cable from mains connection plug 1212 of the
782 IC Column Thermostat.
Remove fuse holder
2
Using a screwdriver, loosen fuse holder 77 and take out com-
pletely.
Change mains voltage
3
Completely remove voltage selection insert 88 by hand, rotate it
through 180° and reinsert it. The required mains voltage (115 or
230 V) must now be visible from the front.
Check fuses
4
Carefully take both fuses out of fuse holder 77 and check their
specifications:
100……120 V 0.5 A (slow-blow)Metrohm-No. U.600.0013
220……240 V 0.25 A (slow-blow) Metrohm-No. U.600.0010
Insert fuses
5
Change both fuses if necessary and reinsert in fuse holder 77.
Install fuse holder
6
Push fuse holder 77 back into the opening of the 782 IC Column
Thermostat by hand until it clicks into place properly.

Two fuses 0.5 A/slow-blow for 100…120 V or 0.25 A/slow-blow for
220…240 V are installed in the fuse holder 77 of the 782 IC Column
Thermostat as standard.
Ensure that the instrument is never put into operation with fuses of
another type, otherwise there is danger of fire!
For checking or changing fuses, proceed as described in section 2.2.1.

3 Operation
Switch instrument on/off
The 782 IC Column Thermostat is switched on and off using
mains switch 99 (see Fig. 2) on the rear of the instrument:
After the instrument has been switched on the two temperature displays 55 and 66 light up and show that the instrument is
ready for use.
3 Operation
IInstrument switched on
0Instrument switched off
Set temperature
The desired heating temperature is set using the two keys 22
and 33. A single pressing of these keys increases or de-
creases the temperature value shown in the lower display 55
in green by 0.1 °C, continuous pressing of these keys leads
to a continuous increase or decrease. A temperature set
once will be preserved even after switching the instrument
off.
Control temperature
As soon as the instrument is switched on the IC Column
Heater is heated to the set temperature. The current
temperature is shown in the upper display 66 in red, the set
temperature is shown in the lower display 55 in green.

4.3 Warranty and conformity
4.3.1 Warranty
The warranty on our products is limited to defects that are traceable to
material, construction or manufacturing error which occur within 12
months from the day of delivery. In such cases the defects will be rectified in our workshops free of charge. Transport costs are to be paid by
the customer.
For day and night operation the warranty is limited to 6 months.
Glass breakage in the case of electrodes or other parts is not covered
by the warranty. Checks which we are asked to carry out during the
warranty period for reasons other than material or manufacturing faults
will be invoiced. For parts manufactured by third parties, insofar as
these constitute an appreciable part of our instrument, the warranty
stipulations of the manufacturer in question apply.
With the regard to the guarantee of accuracy, the technical specifications in the instruction manual are authoritative.
With regard to defects in material, construction or design as well as the
absence of guaranteed features, the purchaser has no rights or claims
except those mentioned above.
If damage of the packaging is evident on receipt of a consignment or if
the goods show signs of transport damage after unpacking, the carrier
must be informed immediately and a written damage report demanded.
Lack of an official damage report releases Metrohm from any liability to
pay compensation.
If any instruments and parts have to be returned, the original packaging
should be used if at all possible. This applies above all to instruments,
electrodes, burette cylinders and PTFE pistons. Before embedding
them in wood shavings or similar material, the parts must be packed in
a dustproof package (for instruments the use of a plastic bag is imperative). If open assemblies are enclosed in the scope of delivery that
are sensitive to electromagnetic voltages (e.g. data interfaces etc.)
these must be returned in the associated original protective packaging
(e.g. conductive protective bag). (Exception: assemblies with built-in
voltage source belong in a non-conductive protective packaging). For
damage which arises as a result of non-compliance with these instructions, no warranty responsibility whatsoever will be accepted by
Metrohm.
