has either turned off or not been turned on. To reset the water heater back to operating
condition, you must:
- Disconnect power from the water heater, remove the bottom cover cap;
- Press the button located in the center of the thermal switch (round shape, near the
heating element) until you hear a click, see Fig. 6;
- If the button cannot be pressed and there is no click, wait until the thermal switch
cools to the initial temperature.
After resetting the thermal switch back to operating condition, perform the above steps
in reverse order.
WARNING!
In case no positive effect has been achieved or the thermal switch turns off repeatedly
within a short period of time, the power supply and water supply to the water heater
should be disconnected, and your local ASC should be contacted for advice or product
repair.
6. To drain the internal tank, use the safety relief valve: unscrew the screw of drain
knob on the safety relief valve and move the drain knob to the up position
— the hot
water outlet tap must be open and the cold water inlet tap must be closed (see Fig. 5).
Water will start flowing from the pressure relief port of the safety relief valve.
WARNING!
Never drain water if its temperature is above 50
°C, as this may cause burns.
7. Remember to check that the safety relief valve is operable every 14 days. Check it
as follows:
- move the drain knob to the up position until you feel the thread and then water should
start flowing out of the pressure relief port. After checking the water flow, return the
knob to the previous position.
WARNING!
If water does not flow, the valve is faulty. In this case, stop using the water heater and
contact the service center.
8. Clean the outer surfaces of the water heater with a damp cloth and soap as
necessary.
