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, The
indicator light will turn blue (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, the indicator light will turn white ,the unit start to
work.
4. METHODS OF USING
When the water heater is working normally (including working state of PUMP),
press TEST button, if the leakage test circuit is no problem, the indicator light
will be off, and the unit will not heat. Press RESET, testing will be canceled,
and indicator light will turn blue or white, the unit will be back to working state
set before. If the circuit leaks, press RESET button can't cancel leakagetesting,
the indicator light keeps off, it means the water heater has problems and can't
be used; all the buttons are invalid, the indicator lights are all off, heating is
stopped, and pump will be closed.
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, the indicator light will keep flickering, 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
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.
4.6 Use After Overheating Protection
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.
