430 RETROFIT INSTRUCTIONS
1. Turn off recirculation pump if used. Close both check-
stops by rotating stems counter-clockwise with an allen
wrench. Open a faucet on the tempered water line, and
ensure water is completely off. If water continues to
flow through the valve, checkstops may be damaged.
In that case, locate another shutoff valve, and turn
water off to the valve.
2. Remove the four (4) screws on the motor housing cap,
and lift the motor housing/cap adjustment knob
assembly from the valve. Note: Depending on your
system, a considerable amount of water may drain
back from your pipes when you remove the cap.
3. Remove the motor from the adjustment knob,
and discard.
4. Place the "O" ring on the stem of the new overload
assembly. Grease the stem of the overload assembly,
and insert it into the adjustment knob.
5. Loosen the union nuts between the checkstops and the
valve body. Remove the four (4) bolts that hold the
motor housing to the valve body. Carefully remove the
valve body. Remove and discard the old overload
assembly.
6. Inspect the valve assembly. Insure the components are
in good shape, clean, and free of debris. Replace pop-
pet assemblies if necessary (available separately).
7. Install the "O" ring onto the motor adapter and assemble
it to the hot water poppet.
8. Install the "O" ring onto the funnel.

into the motor housing. Two legs should be in diagonal
position.
