Recommended Plumbing Setups
The heater requires water flow and positive pressure to
fire and operate properly. It must therefore be installed
downstream of the discharge side of the filter pump. A
typical installation is plumbed as follows:
1.
The inlet side of the filter is plumbed directly to the
discharge side of the filter pump;
2.
The outlet side of the filter is then plumbed to the inlet
of the heater; and
3.
The outlet of the heater is plumbed to the return line
to the pool or spa. The pump, filter and heater are
thus plumbed in series (Salt generators and chemical
feeders must be down stream of the pool heater).
Plumbing from the heater back to the pool or spa must not
have any valves or restriction that could prevent flow when
the pump is operating.
CAUTION:
An additional source of heated water, e.g. a
solar system, must be connected to the main line ahead
of the heater inlet pipe in order for it to act as the primary
heat source. If the primary system provides adequate
heat to maintain setpoint, the heater will not fire. Be
advised that the control panel will then display sensed
water temperatures downstream of the primary heating
system, rather than the temperature of the water exiting
the pool.
Heater must be located so that any water leaks will not
damage the structure of adjacent area. PVC pipe may be
glued directly into the bypass connections.
