4.1 Operating Of The Unit
4.2 Leakage Testing
4.3 To Adjust Water Flow
Switch on the power supply, the unit will take self-inspection for 2s, “ELCB” green
indicator light will be on (under the condition of no electricity leakage). When the
water flow exceeds 1.2L/min, rotate the knob clockwise to switch on heating
power rotate switch, heating indicator light will be on, the unit start to work.
4. METHODS OF USING
When the water heater is working normally , press “TEST” button, if the leakage
test circuit is no problem, “ELCB” green indicator light will be off, and the unit
will not heat. Press “RESET”, testing will be canceled, and “ELCB” green
indicator light will be on, the unit will be back to working state set before. If the
circuit leaks, press “RESET” button can’t cancel leakagetesting, “EARTH”
、
“ELCB” and “POWER” indicator light is twinkling flicker, it means the water
heater has problems and can’t be used; all the buttons are invalid, heating is
stopped.
Rotate the handle of water flow adjusting valve to adjust the water flow.
4.4 Electricity Leakage Protection
When the electricity leakage testing circuit is working normally, if the leakage current is bigger
than certain value between 7.5mA and 15mA, “EARTH”
、
“ELCB” and “POWER” indicator light
will be twinkling flicker, no heating; it can only be used after the failure is excluded. (When
electricity leakage is tested, red and green indicator lights are all off, stop heating.
4.5 To Adjust Water Temperature
Rotate the handle of water flow adjusting valve to adjust to proper water flow. Adjust power by rotating
knob, clockwise rotate, power will be increased and water temperature increase accordingly or vice
versa.
NOTE
For first time using, ensure electrify after the unit is filled fully with water and there is
stable water flow comes out from shower head.
The electric water heater may be damaged if the water hardness is too high. To
guarantee the normal service life, please install and put it into use on condition that the
local water hardness is less than 450mg/L (CaCO3).
If the water flow is small and power is high while using the unit, outlet water temperature is rather
high; the unit will stop heating automatically. At this time, please lower the power and adjust the
water flow faster in order to avoid inconsistency of water temperature.
