When EWH is turned on, press the " + " or " - " key to enter the temperature setting
state, and the set temperature parameters flash. At this time, press this key once, the set
temperature will increase/decrease by 5 on the basis of the last set temperature, and
cycle within 40-80°C. During the setting process, the corresponding setting temperature
indicator flashes. When the temperature setting parameter does not change within 5 sec-
onds, the parameter setting result will be automatically defaulted, and the system will
enter the corresponding working state.
Using smart mode button "Smart" (Fig. 2, p. 4) EWH smart operation mode can be
enabled. In this operation mode EWH can study and record user's habits in using hot
water and prepare hot water in advance for the next water cycle (7 days in a cycle).
When users do not need hot water, it can maintain water at minimum temperature. Thus
comfort and saving of energy can be achieved. This mode is used for those who use hot
water on a regular basis. To enable this mode, press smart mode button "Smart". To
disable the mode, press this button again or switch EWH off.
Press the "Bacteria protection" key to turn on or off the bacteriostatic mode after
power-on (Fig. 2, p. 5). After the bacteriostatic mode is turned on, the bacteriostatic
indicator light is on. Under the bacteriostatic mode, the water heater is bacteriostatic
every 30 days. Bacteriostasis: the bacteriostasis indicator light flashes, the set tempera-
ture is fixed at 75°C, and the system turns to the heat preservation state after heating to
75°C. At this time, the bacteriostasis ends after 30 minutes, and the bacteriostasis indi-
cator light turns to be normally on; During bacteriostatic insulation, when the water
temperature drops by 5°C, reheat to 75°C and keep heating to 75°C.
Note: if the bacteriostasis mode is turned on for the first time, the water heater will
conduct the first bacteriostasis after 3 days, and then conduct the bacteriostasis every
30 days.
When performing maintenance scale on THE is checked. At the same time residue
that may accumulate in the bottom of the EWH is removed. If there is scale on THE, it
can be removed by using scale removing means or mechanically. It is recommended to
hold the first technical maintenance after a year from the time of connection by experts
of a specialized organization and depending on intensity of scale and residue to deter-
mine intervals of follow-up maintenance. This action will extend the maximum EWH
service life.
The first replacement of the magnesium anode shall be made no later than 12
months from the date of EWH installation. In case of no mark of installation in warranty
certificate with the seal of installation company, the period is calculated from the date
of purchase. Regular periodic maintenance and annual replacement of the magnesium
anode in time is imperative to maintain the manufacturer's warranty. Replacement of
