The General Operational Process

1. After fixing to wall and checking all connections, turn on power and water
together.

2.The solenoid valve will now open and fill the tank until it reaches the low water
level sensor.

3. When the low water level sensor is contacted, the filling process stops and the
heating cycle starts, the heating will continue until the water reaches
approximately 98-99ºC.

4. Once this temperature is reached the heating stops and filling restarts, this
process of heat/fill/heat/fill continues until the top water level sensor is reached.
When water makes contact with the high water level sensor, the PCB isolates the
filling cycle from this function, and the element controlled by the PCB remains in
circuit to monitor for any heat top up’s that may be required.

5. If any subsequent water is used and the unit drops away from the high level
water sensor, the heat/fill/heat /fill process restarts until water is back at the high
level water sensor and at maximum temperature.
