SM CS Series Heat Application Considerations | 15 APPLICATION CONSIDERATIONS pressure must always be maintained in the heat exchanger. This can be accomplished with either Well Water Systems control valve or a bladder type expansion tank. Copper is adequate for ground water that is not When using a single water well to supply both high in mineral content.
16 | Application Considerations SM CS Series Heat Pump Cooling Tower/Boiler Systems Consult the specification sheets for piping sizes. The cooling tower and boiler water loop temperature is usually maintained between 50° F Do not overtighten the connections. Flexible to 100 ° F to assure adequate cooling and heating hoses should be used between the unit and the performance.
