Installing Valve Actuators
The EasyTouch 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. Valve
A or Valve B actuators are for general purpose use (solar, water-feature, in-floor cleaner, etc.). For
EasyTouch PL4/PSL4 Control Systems 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.

Valve Handle Operation: To reposition the valve handle:
Rotate the handle to the desired “OFF” position.
The diverter valve handle OFF indicator, represents the current position of the valve’s internal diverter seal
which will stop the flow of water. The valve handle stop-pins determine the position of the diverter valve’s
internal seal to stop or allow water flow. Note: When a motorized valve actuator is installed, stop-pins are not
required.
Handle Stop-Pins Positions:
The two movable stop-pins can be set to allow the valve handle’s position to
completely stop the flow of water, regulate a limited flow, or allow the maximum flow. To set the stop-pins:
Insert the stop-pins in the pin holes according to the corresponding “degree indicator” displayed on top of
the handle. The stop-pin positions can be set to 180°, L90° (left-side) and R90° (right side). Repositioning
of either stop-pins allows the handle to be set to any desired percentage of water flow.
