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 compo-
nents which are live. Hence, always disconnect the instrument from all
voltage sources before you open it and ensure that the mains cable
is 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.

2.1 Setting up the instrument
782 IC Column Thermostat 7
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
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 op-
eration, free from vibrations and protected against a corrosive atmos-
phere 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:
1Disconnect mains cable
Disconnect mains cable from mains connection plug 1212 of the
782 IC Column Thermostat.
2Remove fuse holder
Using a screwdriver, loosen fuse holder 77 and take out com-
pletely.
3Change mains voltage
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.
4Check fuses
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
5Insert fuses
Change both fuses if necessary and reinsert in fuse holder 77.
6Install fuse holder
Push fuse holder 77 back into the opening of the 782 IC Column
Thermostat by hand until it clicks into place properly.

2.2.2 Fuses
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.
2.2.3 Mains cable and mains connection
Mains cable
The instrument is supplied with one of three mains cables
• 6.2122.020 with plug SEV 12 (Switzerland, …)
• 6.2122.040 with plug CEE(7), VII (Germany, …)
• 6.2133.070 with plug NEMA 5-15 (USA, …)
which are three-cored and fitted with a plug with an earthing pin. If a
different plug has to be fitted, the yellow/green lead (IEC standard)
must be connected to protective earth (protection class 1).
Any break in the earthing inside or outside the instrument can make it
a hazard!
Mains connection
Plug the mains cable into mains connection plug 1212 of the 782 IC Col-
umn Thermostat (see Fig. 3).
2.2.4 Switching the instrument on/off
The 782 IC Column Thermostat is switched on and off using mains
switch 99. When the instrument is switched on the two temperature dis-
plays 55 and 66 light up.

3 Operation
782 IC Column Thermostat 13
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:
IInstrument switched on
0Instrument switched off
After the instrument has been switched on the two tempera-
ture displays 55 and 66 light up and show that the instrument is
ready for use.
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.
