General
All models must be moved and installed in an upright position. Ensure stable positioning
and tip safety. Make sure that there is a sufficient supply of fresh air for the circulation
pump and the compressors. The warm exhaust air must be able to freely exit toward
the top. Connect the cables for the mains power as well as the connections between
HT-Thermostat and control unit.

The temperature control device can be refitted from 230V / 50Hz to 400V / 50Hz or
vice-versa. This refitting must only be performed by a qualified electrician. Erect the
temperature control device at the intended location. A distance of 20 cm between the
wall and the back panel must be adhered to in spite of possible water cooling.
The max. current pickup during the operation with 230V is slightly lower than 16A. But
as there are 230V circuits with smaller fuses, we ask you to adapt the current pickup
of your temperature control device to your circuit during the initial installation. Besides
16A, 13A or 10A can be selected as a current pickup. If you select 13A or 10A, the
heat output will be reduced accordingly from 1,500 W (with 16A) to approx. 1,100 W
(with 10A) as soon as the compressor is connected. If the compressor is turned off,
you will be able to use the entire heat output. This does not negatively impact the
regulation function. You can always perform a current adaptation under the menu item
Limitations (e.g. if you would like to switch from a 230V / 10A circuit to a 230V / 16 A
circuit).
Cooling water connection I
(valid for unistat cc401)
The model unistat cc401 has a cooling water connection, which allows a compensation
of the self-heating (heat input of the pump motor) as well as a temperature reduction. A
compensation of the self-heating only makes sense if you wish to realise prerun
temperatures in the range just above the cooling water input temperature. A
temperature reduction makes sense if your reactions take place at relatively high
temperatures and if a cooling-off to a lower temperature would only take place by
radiation at this point.
