OPERATION
IEWH heats water flow instantly, passing it through heating elements. The temperature of inlet wa-
ter can vary significantly throughout the year: from 5°C in winter to 20°C in summer. Therefore, the
same temperature outlet water of IEWH in winter can be significantly less than in summer.
IEWH must be disconnected from power supply network in case not using for a long time.
If IEWH do not use in the winter time and there is water freezing possibility it’s recommended to
turn off the power and drain the water from IEWH.
Trend 4500 / 6000 operation:
The water heater has temperature control from 35°C to 50°C.
Device is energy effective owing to automatically adjusting power for selected outlet water flow
temperature
IEWH automatically maintains selected water temperature in case of fluctuations temperature and
pressure in the water inlet. Ensure that the power and operating pressure are in accordance with
technical specifications table.
IEWH automatically determines type of installation (under sink / over sink) and displays infor-
mation on the front panel correctly.

Step 0.
Turn on the power, open the hot water tap and wait about 10-15 seconds.
Step 1.
Hot water tap opened, press power button, touch keys will light up, then press power but-
ton again. In 2 seconds front panel will display the default outlet water temperature (38°C), then
the device will display the actual temperature.
Step 2.
Hot water tap opened, set the desired outlet temperature. In 2 seconds front panel will
display the adjusted temperature, and then the device will display the actual temperature, heating
the water till the temperature adjusted.
If device has not reached adjusted temperature, it’s necessary to adjust (decrease) water flow. If
necessary temperature is not reached yet with minimal water flow, the power of the device is not
enough to achieve necessary temperature value at the current temperature of the inlet water (in
the water supply system).
