8.14 Plumbing the System
1. Feed and return connections to the array are made by inserting PVC grooved pipe to panel
adaptor into the panel EPDM hose and gluing the PVC pipe to the adaptor. Never attempt
to glue pipe directly to the solar panel header (see fi gure 12).
2. An end cap (item #6) must be plumbed into the array at the opposite end of the bottom
header to the feed line. If necessary, this end cap will totally drain the panels when the sys-
tem is winterized. More end caps can be used in the plumbing to facilitate drainage.
3. Isolating valves (optional), plumbed in the array feed and return lines, near the electronic
control, are recommended so that the array can be isolated if desired.
4. With a pool fi ltration system far from the house, where the solar panels are installed, feed
and return lines are buried (see fi gure 19). Flexible corlon polyethylene piping is suggested
because it is more resistant to freezing. Rigid PVC pipe may freeze and break. Install drain
plugs at the both ends of the underground pipes using the underground kit K15UNG (see
para 5 –Parts List).

5. Insulation is not needed since the pool water temperature and ambient air temperature are
almost the same. Winter conditions of snow and ice make it imperative that the system be
checked once a year by a qualifi ed installer: solar panel mounting straps, sensor wire, caulk-
ing, piping fastening and pipe drainage.
