4.1 Operating the unit
4.2 Leakage Testing
4.3 To Adjust Water Flow
Switch on the power supply, the unit will conduct a self-inspection for 2
seconds. ELCB green indicator light will turn on (If there is no current
leakage). Rotate the knob clockwise to switch on the unit and the indicator
light will turn on. The unit is now working. If not, the water flow may be lower
than 1.2L/minute.

TEST
RESET
When the water heater is working normally, press TEST button. If the leakage
test circuit has no problem, the ELCB green indicator light will be off, and the
unit will not heat. Press RESET, testing will be canceled, and the ELCB green
indicator light will be on. The unit will then be back to the working state set
before. If the circuit leaks, pressing the RESET button won’t cancel leakage
testing. The ELCB & POWER indicator lights will flicker, meaning the water
heater has problems and cannot be used. All buttons won’t work and there will
be no heating.
Rotate the handle of water flow adjusting valve.
4.4 Electricity Leakage Protection
When the electricity leakage testing circuit is working normallyand if the leakage current is bigger
than a value between 7.5mA and 15mA, the red POWER and green ELCB indicator light will be off
with no heating; it can only be used after the failure is solved.
4.5 To Adjust Water Temperature
NOTE
For first time use, ensure that the power is turned on only after the unit is filled fully with
water and there is stable water flow coming out of the shower head.
The electric water heater may be damaged if the water hardness is too high. To guaran-
tee the normal service life, please install where water hardness is less than 450mg/L
(CaCO3).
If the water flow is low and power is high while using the unit, outlet water temperature will be high
and the unit will stop heating automatically. At this time, please lower the power and increase the
water flow 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
the knob clockwise or counter clockwise and the water temperature will increase or decrease
accordingly.
