6Operation
The electronic continuous-flow heaters of this series operate
automatically.

switches on. The water is heated as it flows through the
appliance. The over-sink appliances TR4000 6 EB and
TR4000 8 EB feature an automatic operation indicator.
The operation indicator lights yellow at half power and red
at full power, dependent on the water flow rate.

6.3 Regulating water temperature
• Open the tap fully, and the appliance switches on.
• Now increase the temperature of the water by reducing
the flow of water.
Info: In winter, the temperature of the water supply may be
lower, so that the temperature of the water leaving the tap will
not be reached. Please proceed as described under “Water
connection”.
