Before switching any power on, it is ensured that the heater is full of water and that water is flowing through it. The mains power is then switched on, followed by the on/off switch on the heater. A red indicator shows that the heater is powered. An amber light on the heater indicates that the filter pump is in operation. If the pump does not operate or if the pump interlock has not been fitted, the heater will not heat. The desired pool temperature is now set using the thermostat dial. A green light on the heater indicates that the heating elements are powered and water is being heated. When the set temperature is reached, the green light is extinguished. A white light on the heater indicates that the water temperature is below the factory set safety thermostat trip level. If this temperature is reached, the heater has overheated. In this case, the safety thermostat trips and the unit is shut down. This trip must be reset manually. In normal operation, the green light will only be lit (and heating will occur) if all the other lamps are lit and the pool water temperature is below the set temperature
