The water heater must be connected with water inlet and outlet pipes. Other metal parts of the water heater with
which the user may come in contact with and which may come in contact with water, shall have permanent and
reliable connection to ground conductor. The electric supply wiring shall incorporate multi-pole circuit breaker
with 3 mm contact opening. Automatic fuse may also be used as circuit breaker.
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.
