How does the optional in-line heater work?
A. The In-Line Heater is totally automatic. When the pump is turned on, water is pumped through the whirlpool system. The water pressure activates a pressure switch inside the heater to turn it on. When the pump is on, the heater is on. When the pump turns off the heater turns off. The heater is designed to maintain the temperature of the water and has a high-limit cutoff set @104*F The heater has an indicator light which will be lit when the heater is on – it is on the heater itself and not visible without opening the tub’s access panel.
