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, 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 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.

CONNECTIONS (POLYMER HEADER)

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.

P-R185B To P-R405B, C-R185B To P-R405B, P-R185BL To P-R405BL, C-R185BL To C-R405BL, RP2100 specifications

Raypak offers a comprehensive line of boilers and water heaters, notably the P-R185B to P-R405B and C-R185B to P-R405B series, along with the RP2100 model. These products are engineered for efficiency, reliability, and performance in both residential and commercial applications.

The P-R185B to P-R405B series features a range of input capacities from 185,000 to 405,000 BTU/h, making them suitable for various heating requirements. The P-R series is equipped with Raypak's patented Cupro-Nickel heat exchanger, which offers superior corrosion resistance and extended life in challenging water conditions. These units also utilize a sealed combustion system, allowing for efficient operation and reduced energy consumption by drawing air from outside the building.

The C-R185B to P-R405B boilers are specifically designed for commercial applications where reliability is critical. They incorporate similar features to the standard P-R series and are built to handle higher heating demands, making them ideal for larger facilities. The C-R series models are recognized for their durable construction and advanced control systems, offering precise temperature management and enhanced performance.

In addition to these series, the P-R185BL to P-R405BL and C-R185BL to C-R405BL models feature a low-NOx design to comply with stringent environmental regulations. This means they produce lower nitrogen oxides, making them an environmentally friendly option without sacrificing performance.
