All first generation solar pool heater documents apply to SolarAttic's second generation solar pool heater except for some electrical wiring diagrams and unit specs. When we created our second generation solar pool heater, we changed the motor spec from 220 vac to 115 vac to make it easier from an installation standpoint. Also, the second generation solar pool heater incorporates a smaller physical footprint to make it easier to install through smaller attic openings. The second generation solar pool heater can be installed through a small 2x2 foot closet opening. The first generation solar pool heater often required a custom and larger attic opening. The manual supplied with the first generation solar pool heater is more comprehensive than the manual supplied with the second generation solar pool heater. It contains a theory of heat transfer section including heat transfer curves and other solar design data that the second generation solar pool heater does not incorporate. This reference material shown in the manual of our first solar pool heater also applies to the second generation solar pool heater as the heat transfer factors of both solar pool heaters are almost identical for the heat exchanger units used. Because the design material presented in the first solar pool heater manual is not reproduced in the second manual, we have left this material online to download as needed. Many of the plumbing diagrams linked below complement the second generation solar pool heater diagrams supplied in the PCS2 Installation and Operating Manual. The PCS1 is no longer manufactured. See the second generation solar pool heater link above for the latest information.
