Connect the EPDM mat inlet and outlet. In case of using 50mm PVC, use PVC glue. The ideal
location of the EPDM mats is just after the filter, before the heatpump. In all cases, the water
treatment has to be done after the heating mats, never before. We recommend to use a
(automated) 3-way valve to bypass the solar heating in case the roof temperature is colder than
the pool water temperature. See the connection scheme.
Safety Precautions
Do not put the EPDM heating in a environment higher than 60 degC
Do not pressure higher than 1.5 bar on the EPDM heating
Do not circulate water with pH lower than 7.2 or higher than 7.6 through the heating mats.
Do not ciruclate water with free chlorine content higher than 1ppm over the heating mats.
Do not walk over the collectors
Use appropriate safety precautions / equipment when working in height
Winterizing
Empty the collectors before winter. EPDM rubber will not freeze, the collectors will freeze when left full
with water.
