The unit can work in conjunction with a single-handle, two-valve tap.
The unit must not be installed in the place which is exposed to the danger of
explosion and place in which the temperatura may go down below 0°C.
Unit’s cover must not be taken off while power is on.
Failure to install the fi lter on water supply pipe can cause unit damage.
Accumulation of limescale in parts ofthe water heater may cause limited water
fl ow and failure of the water heater. Failure of the heater and damages caused
by the limescale will not be covered by the warranty. The water heaters and fi
ttings must be descaled on the regular basis, the frequency of limescale
removal depanding on the quality of water.

Unit doesn’t heat up the water / water temp. is too low:
Power supply failure
Water flow rate is too low (e.g. fi lter is blocked with impurities, improper
water flow regulation)
There is no bridge connecting terminal clamps U and V for single phase supply
lf there is a fault in the unit, contact the nearest authorised service.
