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.
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.
