Do not plug the water heater in HDO socket; it would not work properly in SMART
mode. The SMART mode (SMART HDO) will only work if 24/7 connected to power
supply.

In the electric wiring casing remove the partition corresponding with the input wire diameter of 8 or 10
(Figure 5). The degree of protection of electric parts of the heater is IP 44. Power input of electric element
is 2200 W.
