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

open-non-pressure connecting system the water starts dripping from the water tap.

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
