4 Installation and operation
4.1 Installation
1. Site the Peltier unit on a firm, uncluttered surface. Maintain at least 6 centimetres spacing on all
sides (air access).
2. With the switch set to the "0" position, connect the power supply unit to the electrical mains
network (100...240 V) and connect the plug securely to the Peltier device ("Power").
3. Connect the temperature sensor to the Peltier device ("Sensor").
4. Fill the thermostatic block with 6...6.5 ml of tempering liquid using the filling syringe.

The thermostatic block should be sufficiently filled,
but not overfilled. Too little tempering liquid reduces the
heat transport and can lead to the system switching to
EMERGENCY OFF.

The devices are rated for operation with non-
flammable and flammable liquids according to DIN EN
61010-2-010. Watch the filling level.

Generally, decalcified water is used as the temper-
ing liquid. Please ensure that the evaporation rate re-
mains low, so that sufficient tempering liquid is always
available. Please note that with an unsuitable choice of
medium condensate interacts with the sample in your
beaker. Please ensure that your tempering liquid does
not interact with the thermostatic block (material: ano-
dised aluminium).
