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.
