Connection to water supply network
Take into account instructions for installation, connection and use of the water heater.
Make sure the water heater cannot be switched on when empty.
Starting up
Fill the heater with water before connecting to the power supply network. Supervise
the first heating cycle. During the heating cycle, the water expands and with closed-
pressure connecting system the water starts dripping from the relief valve, while with
open-non-pressure connecting system the water starts dripping from the water tap.
Monitor the automatic switching off of the thermal regulator.
Any repairs should be made using original spare parts only!
User's instructions
1. Occasionally remove the lime scale deposits on the electric heating element (the
intervals depend on the hardness of water of your water supply and on the operating
conditions. We recommend installing a device for regulation of water hardness or you
can reduce the temperature for heating the water. Any damages resulting from
damaged electric heating element caused by lime scale depositing, shall not be
covered by guarantee.
2. Taking into account the quantity of hot water required, the temperature in the water
heater is continuously adjustable with thermal regulator. Maximum setting of the
temperature is ca. 75 °C, and minimum temperature setting is ca. 9 °C. When setting
to 75 °C, the temperature is reduced to ca. 65 °C before the heater is again switched
on. In order to prevent lime scale depositing on the heating element, we recommend
setting the thermal regulator to temperature setting lower than 60 °C, as evident on
the drawing bellow:
3. In case of malfunctions or defects during the operation of the heater, call the
nearest authorised service provider. An expert will repair the malfunction or defect in
no time and will restore the operation of the water heater.
Do not try to repair the heater by yourself! Call the nearest authorised service
provider.

The heaters with heating pump enable the water for sanitary use to be heated by
alternative sources of energy (e.g. central heating, solar power, ...) by installing one
