Installing the Actuator on the Valve Body:
1. Position the actuator so that the “D” shaped valve
stem aligns with the “D” shaped drive cavity in the
operator
2. Slide the actuator onto the valve stem and rotate to
align the valve’s 2 locking posts with the mating
holes in the actuator. Push in the release clip and
slide the actuator down flush to the valve body.
3. Verify that the actuator is locked by pulling it away
from the valve body without pushing in the clip.
(Do not use excessive force.)
Mode of Operation:
1. Upon initial field installation the capacitor requires
a full charge, up to 25 seconds before the valve starts
to turn. Charging time will vary (typically less) dur-
ing normal operation.
2. When the capacitor is charging the green LED light
will FLASH.
3. Once the capacitor is charged the green LED will
stop flashing but remain ON, at this point the
valve’s actuator will rotate the ball valve. The green
LED will remain ON as long as the thermostat is call-
ing (the unit is powered).
4. Once the thermostat is satisfied the green LED will
turn OFF and the valve will rotate 90° into its nor-
mal position or non powered position.
WARNING: Do not use zone valves on indirect
water heaters without a tempering device.
