NOTE:

-Damage to the Indirect Pool Heater due to improper water chemistry is not covered under the warranty

-Chlorine feeder must be installed after (downstream of) the Indirect Pool Heater and be installed with an anti-siphoning valve to prevent chlorine from backing up into the Indirect Pool Heater.

-This is only a conceptual drawing. A qualified installer must determine whether this system setup will work in each application. Installer must also ensure compliance with code requirements.

On the pool side the flow may be variable either due to variable speed pumps or changes in the pressure drop through the filtration system. These variances can be accommodated by installing a 2lb spring loaded check valve in the bypass line along with a manual valve (see Figure 2 for details).

On model sizes 045 to 495, the check valve will con- trol bypass flow by directing all flow through the exchanger under low flow conditions, and avoiding excessive flow through the heat exchanger under high flow conditions. On 995 models the 2lb check valve does not provide enough resistance to direct adequate flow through the heat exchanger, and must be aug- mented by using the manual valve to throttle flow to provide approximately 6 to 15 ft of head across the 995 exchanger.

Controls

The Indirect Pool Heater must be installed with tem- perature and flow control s to protect the heat exchanger and control water temperature supplied to the pool or spa. The return from the pool/spa must be controlled at the inlet to the Indirect Pool Heater by a thermostat set to the desired temperature for the pool/spa, with the maximum recommended operating

temperature of 104°F. A second temperature control must be installed in the outlet piping of the Indirect Pool Heater to limit pool/spa supply temperatures to 140°F maximum. In addition to the temperature con- trols, a flow switch should be installed in the pool/spa supply line to prove adequate flow through the heat exchanger. All three of these controls must be satis- fied to provide a call for heat to the heat source.

Chlorine feeders or salt water generators

The chlorine feeder or salt water generator (with CR24 exchangers only) must be installed after (downstream of) the Indirect Pool Heater and be installed with an anti-siphoning valve to prevent chlorine from backing up into the Indirect Pool Heater. During periods of high or fluctuating chlorine levels the Indirect Pool Heater must be isolated from the system by closing the isola- tion valves, protecting the unit from chemical damage.

CAUTION: Operating control, high limit and flow switch are NOT part of the Indirect Pool Heater. These items must be supplied separately.
