tab or push the button of thermal block manual
control and wait until the thermal block is opened (Fig.26).
2. If it is the first start of the instrument, rub the wells of the thermal block with a cloth mois-
tened in alcohol (96-% ethanol or 100-% isopropyl alcohol may be used) as described in sec-
tion 8 of instrument maintenance. In the course of operation, wipe the wells as set forth in the
Maintenance section.
3. Place the tubes with samples into the thermal block wells in compliance with filled in plate
protocol.
4. Click
in

window or press the button of instrument manual
control and wait until the thermal block is closed.
Caution!
Be sure to place at least 8 tubes in order to prevent their damage because of
hot lid pressure. If there are less of 8 tubes please add empty tubes of the same height to
make them as it is required.
Caution, dangerous!
The instrument provides automatic loading and unloading of
tubes from the thermal block in the operational position. The command to move (open or
close) of the thermal block comes from the operator. It is forbidden to carry out any manipula-
tions during the movement of the thermal block because it can lead to damage of the move-
ment mechanisms of it.
If an obstacle appears in the process of the thermal block closing, it
automatically switches to the opening mode.
To prevent the failure of the movement mecha-
nism in case of a mechanical obstacle occurs during the movement of the thermal block, the
front panel of it is made flexible.
