3. PLACE THE SHUT-OFF SERVO
B. Position the center of the servo motor over the center of the shut-off valve
Carefully place the servo and brackets over your shut-off valve and inlet pipe as shown
here. Close the brackets over your inlet pipe.
Position the servo over your shut-off valve so that the center of the servo’s motor is
directly over the center of your hot water heater’s shut-off valve as shown. The servo’s
centering ring should fit over the shut-off valve’s nut (if it doesn’t fit, see the section at
the top of the next page).
IMPORTANT: Keep the centers of the the servo motor and shut-off valve aligned
throughout the installation and make sure they’re aligned when you’re finished.

A. Turn your hot water heater’s shut-off valve on and off several times.
Depending on how long it’s been since the shut-off valve was last used, there might be
significant build-up (like mineral deposits) around the valve and handle, which makes
the valve more difficult to close. Opening and closing the valve loosens this build-up
and makes the valve easier to open and close.
IMPORTANT: Leave the shut-off valve in its open position when you’ve finished opening
it and closing it.
