Operation
Water circulation
The circulation pump pumps water from the sump through a triple filter system
to the heater. When water enters the heater, a flow switch determines water is
present and allows the heater to be activated. As water flows, it's heated until it
reaches the pre-set temperature determined by the cycle. Once it leaves the
heater, it flows through the sump into the upper and lower spray arms.
