water supply valve. The electric water heater will start filling with water.
When water flows from the hot tap freely, it means the water heater is fully
filled with water and you can close the hot water outlet valve.
During normal operation the cold water supply valve must be set
1.2 Plug the power cord into the outlet, at that an indicator light on GFCI
and temperature controller handle lighting will light up.
1.3 Press the temperature controller handle and hold it for a few seconds, at
that indicator lights will start flashing for some time, showing the set water
heating temperature, after that indicator lights will show water heater's
2. Water heating temperature setting
2.1. Water temperature in the water heater can be set within the range +5°C
2.2. Turning the temperature controller handle clockwise (from ´minµ to
´maxµ), you increase the water heating temperature, at that the number of
indicator lights on the control panel increases.
2.3. Turning the temperature controller handle counterclockwise (from
´maxµ to ´minµ), you decrease the water heating temperature, at that the
number of indicator lights on the control panel decreases.
2.4. The water heater automatically maintains water temperature. When
water temperature in the water heater reaches the temperature, set by the
user, the heating is automatically switched off, at that ´heatingµ indicator
light on the control panel lights down. When water temperature in the
water heater drops to a certain level, the heating is automatically switched
off, at that ´heatingµ indicator light on the control panel lights up.
When setting temperature, having reached the optimal heating

tank (in case of equipment failure).
3. Power mode selection
3.1. Press the thermostat knob several times to select the desired heating
3.2. If you select low heating power then ´energy saveµ indicators light up, if
you select medium heating power then ´normal heatµ indicators light up, if
you select high heating power then ´energy saveµ and ´normal heatµ
indicators light up simultaneously.
3.3. After the heating mode is selected, ´energy saveµ and ´normal heatµ
indicators are on for 10 minutes, then they light down.
4. Switching off
Press the temperature controller handle and hold it for several seconds to
switch off the appliance, at that indicator lights will light down and the
temperature controller handle lighting will stay on.
