SolarSystemStart-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
shouldbeactivatedwheneverthepoolcleanertimerison.Momentarilyturnpoolcleaner
on and off to check the motor is operating correctly.
3. CheckthatSolarValveisin“solarbypass”position,divertingwaterawayfromsolarpanels.
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. CheckthatSolarValvehasrotatedfromthe“solarbypass”positiontothe“solar”position,
diverting water through the solar panels.
5. The system is now ready to be operated as desired.
Pool Cleaner Protection
Recommendedforuseinpoolsystemswhichutilizea“boosterpump”poolcleaner.Thisfeature
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.
