SunTouch Pool and Spa Control System Installation and User’s Guide
Solar Hydraulics System
Plumb the SunTouch solar system in accordance with recommended hydraulics shown below.
• 2” diameter plumbing is advised to ensure maximum flow of water through the solar panels. A solar
booster pump should be added if panels are installed at a very high elevation.
• It is recommended that the solar panels are mounted in a way that gravity will allow draining
whenever the filter pump is not on.
• For systems with glazed panels, damage can occur from overheating if the filter pump is still running
after the solar has turned off. To enable glazed panels to automatically drain whenever the solar turns
off (even if the filter pump is still running), a 1/2” motorized solar drain valve should be plumbed from
the solar feed line, through a check valve, to a zero psi point (such as pool fill line or jet air intake).
