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).
Solar System Start-Up
1. Switch power on to the EasyTouch PL4/PSL4 Control System Power Center.
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.
