6. Lubricate the bonnet “O”-ring and install onto existing
bonnet assembly.
7. Place the wax element into the stem assembly, small
end first and place this bonnet-stem-motor assembly
into/onto the valve body. Rotate the bonnet assembly to
line up the bonnet screw holes and reinstall and tighten
the four bonnet screws.
See cut-away below to see how everything goes together.
8. With handle, rotate the stem assembly clock-wise, until it
bottoms out on the cartridge. At this point your valve is
in the off position.
9. Turn the hot and cold water supplies back on and verify
there is no leakage.
Caution: Set valve “off” position with bare hands only! Over
tightening in the off position with pliers or a wrench can
cause internal valve damage.
Note: There is no temperature adjustment for this kit.
Full hot (110°F ±5°F).
If flow does not stop, something is wrong with the
installation. Turn off both supplies, disassemble the
valve, and go back to “reassembly” – step #1.
10. Your valve should now be set properly. Verify proper
operation by rotating the stem from the off position,
counter-clockwise, to the high temperature position.
Verify the temperature does not exceed your desired
maximum temperature. Rotate stem back to the off
position.
11. Replace trim plate and handle.
12. Your retrofit is complete!
