SunTouch Pool and Spa Control System Installation and User’s Guide

SunTouch Solar System Installation

• 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).

SunTouch Solar System Start-Up

1. Switch power on to the SunTouch Power Center.
Note: If pool cleaner protection has been added to the system, the pool cleaner pump motor
should be activated whenever the pool cleaner timer is on. Momentarily turn pool cleaner
timer on and off to check that the motor is operating correctly.
2. If pool cleaner protection has been added to the system, the pool cleaner pump motor should be
activated whenever the pool cleaner timer is on. Momentarily turn pool cleaner on and off to check
the motor is operating correctly.
3. Check that Solar Valve is in “solar bypass” position, diverting water away from solar panels. If Solar
Valve is staged incorrectly (diverting water to the solar panels), reverse switch on back of Valve
Actuator (change from ON1 to ON2, or vice-versa). The Valve Actuator will automatically rotate to
the correct position.
4. Check that Solar Valve has rotated from the “solar bypass” position to the “solar” position, diverting
water through the solar panels.
5. The system is now ready to be operated as desired.

Pool Cleaner Protection

Recommended for use in pool systems which utilize a “booster pump” pool cleaner. This feature automatically
turns off the pool cleaner pump for a few minutes whenever solar is initiated. This will protect the pump from
damage caused by air in the solar panels at system start-up.
