PLUMBING FOR WATER CONNECTIONS

HEATER LOCATION (Relative to the pump and filter)

The RP 2100 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.

Plumbing from the heater back to the pool 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 set-point, the RP2100 heater will not fire. Be advised that the RP2100 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 header unions.

Before attaching the 2-inch unions to the inlet/outlet header, make sure the o-rings are properly seated in the grooves. Use AquaLube or equivalent non-petroleum based lubricant on the o-ring. Hand tighten the unions. Glue PVC piping directly to the unions.
