Operation Method2) Prompt Heating TypeFor saving waiting time of your bath, increasing heating speed of water heater, and enlarging outlet of hot water ofwater heater, it is suggested that you select prompt heating mode to use this unit according to the following way indifferent seasons:z Operation in summer: Because the water temperature of tap water in summer is relatively higher (around28℃). During the bathing period, you can directly select the prompt heating mode to heat the water, whichwill save time while saving energy.z Operation in spring, autumn and winter: During these three seasons, the temperature of tap water is relativelylower, while the demand of hot water is relative higher during the bathing process, you can adjust the waterheater to “medium-temperature heat preservation” of “water storage type” or “preservation” mode to preheatwater. When the temperature of hot water is at a range of 35℃~40℃, you can use the “prompt/storage”button to adjust the working mode of this unit to prompt heating mode to take your bath, thusly meeting yourdemand of hot water while greatly shortening waiting time of your bath.In addition, when there are many people to take bath, you also can adjust the water heater to “water storagetype” mode to preheat water, and then start the prompt heating mode to take a bath.z Note: At the initial stage after the startup of prompt heating mode (the first 1~2min), the temperature ofoutlet water will have minor variations. Please firstly adjust the water to the proper temperature and then takebath in order to ensure the comfortableness of your bath. Conversion Method of Prompt Heating ModeUnder any water storage type of startup status, press the “prompt/storage” button to enter prompt heating mode,“prompt heating type” will be illuminated, the time will count down with the limitation of 30 minutes, and thedisplay panel will indicate the decrease in the range of 30:00~00:00. If the system detects that the water flow isgreater than or equal to 2L/min, this unit will execute heating in the implied power of 3000W, and the “heating”symbol will be illuminated. Within the working time period of prompt heating (30min), if the system hasn’tdetected water flow (e.g., the outlet valve is closed) or if the water flow is less than 2L/min, the working of theheating tube shall be immediately stopped, and this unit will be under heat preservation status, the “heatpreservation” symbol will be illuminated, the count-down will continue. After the finish of the count down, it willreturn to the previous working status (some water storage type prior to entrance of prompt heating mode. You canuse the “prompt/storage” button to re-enter into prompt heating mode.3. Temperature SettingUnder status of startup (the display screen has no any digital flashing indication), press ∧ or ∨ to entertemperature setting status to set the temperature (digital readout flashing quickly). The temperature value isvaried within the range of 35~75℃ with intervals of 5℃. Under standard mode, you can directly use ∧ or∨ to adjust and set temperature; and under medium-temperature heat preservation mode, the impliedmaximum heating temperature of this unit is 40℃, which can’t be adjusted.4. Correcting the ClockThe clock is a twenty-four hour system, 60 minutes, and the second digit will be indicated flashing and thesecond digital will travel.11Prompt Heating TypeActualHeating (Fig. 9)
