PL4/PSL4 Control Systems can control up to four automatic valve actuators. Two
of the valve outputs are dedicated to the pool/spa intake (INTAKE) and return (RETURN) valves.

ForEasyTouchPL4/PSL4ControlSystemsharedequipmentsystemstherearetwomotorizedvalve
actuators (CVA-24T, P/N 263045) provided in the kit.
To install the valve actuator (two-way valve example shown):
1. Remove the valve knob, handle and the four screws, from the valve cover (indicated with
arrows).
2. Align the splines of the actuator shaft over the shaft of the valve.
3. If the actuator is not aligned with the mounting holes on the valve cover, rotate the actuator
(while still attached to the valve) until the actuator is positioned correctly over the valve.
4. Secure the actuator with the screws provided. Only use self-tapping screws when required.
5. Mountthevalvehandleandknobontotheactuator.

Adjusting the valve position
(3-wayvalveshownbelow)
If the valve rotates to the wrong position, adjust
the switch on the back of the actuator between
ON1 and ON2 positions. This will rotate the valve
to the correct position. The following diagram
shows the standard plumbing and valve actuator
position.
