Raypak C-R185A, RP2100 Flow Rates Model Pipe Size MIN.GPM MAX.GPM, Connectionsplasticheader

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, i.e. 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 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.

FLOW RATES

MODEL	PIPE SIZE	MIN.GPM	*MAX.GPM
185	1-1/4"-1-1/2" - 2	20	125
265	1-1/4"-1-1/2" - 2	25	125
335	1-1/4"-1-1/2" - 2	35	125
405	1-1/4"-1-1/2" - 2	40	125

*When flow rates exceed maximum GPM an external auxiliary bypass valve is required. See external bypass valve section for details.

CONNECTIONS(PLASTICHEADER)

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. Tighten the unions hand tight. Glue PVC piping directly to the unions.

This is not the same as the Schedule 80 PVC pipe which is also colored gray. PVC may be used immediately after the CPVC adapters.

2" CPVC Adapters

Inlet/Outlet Header PVC Pipe

CAUTION: NEVER install PVC directly into header flanges. Use the 2" CPVC adapter supplied loose with the heater.

DO NOT use petroleum base assembly fluids (such as Petroleum Jelly or lubricating oil). If assembly lube is required, use a silicon base such as Amoral etc.

There are two sets of flange gaskets supplied with your heater. Use the appropriate gaskets for all your heater connections. Discard unused set.

GASKET DESIGN #1: Accepts 1-1/2" copper tube or

1-1/4" galvanized pipe as a slip connection. GASKET DESIGN #2: Accepts 2" copper tube as a slip connection. The flange is threaded for 2" screw in pipe connections. Also used with the 2" CPVC adapters.
