7.1 A qualified technician must perform the installation and first start-up of the ap-
pliance, in line with the relevant national regulations in effect, and any other re-
quirement set out by the local governments or public health institutions.
7.2 Open the closing valve (Item 1, Figure 4) and the hot water tap, but leave the cold
water tap closed. The incoming water will fill up the tank. Let the water flow for a
few minutes to flush the appliance, then close the tap.
7.3 Power on the appliance using the main switch. Use the temperature regulator
knob to set the desired temperature. The indicator light will illuminate during the
heat-up time.
7.4 During heat-up, excess water may leak through the outlet of the combined safety
valve due to expansion. This pipe must be left open towards the air space.
7.5 At the end of the heat-up time, when the water reaches the preset temperature,
the regulator switches off. When about 15% of the water is discharged, the regu-
lator should switch back on automatically. If the heating fails to turn on, contact a
technician.
8.1 Temperature limiter
Upon failure of the regulator function, the limiter protects the hot water tank
from harmful overheating by breaking the heating circuit before the water tem-
perature reaches 75 °C.
The limiter must be reset by a professional after resolving the cause of the over-
heating.
8.2 Temperature controller
The temperature of the water stored in the hot water tank can be controlled out-
side with the help of the turn button without levels, in order to set water temper-
ature .
Turning the button fully counter clockwise, the temperature controlling device
gets into zero state.
Turning the controlling button clockwise, the desired temperature can be set at
higher degrees, see Figure 9.
8.3 Radiator
In case of failure, the replacement of the radiator requires disconnection from
the electrical network and the discharge of water, as well as the removal of the
bolts in the service cover.
The repair must be executed by a professional.
8.4 Active anode
The hot water storage tank is additionally protected against corrosion by active
