Hot Temperature Adjustment (cont.)
Insert a thermometer into the water stream to verify the water
temperature.
Turn the valve stem clockwise until the maximum 120° F (49° C)
temperature is reached.
Reinstall the valve spline adapter with the adapter tab placed
flush against the left side of the hot tab on the cartridge.
Reinstall the valve spline adapter in this position over the valve
stem.
Shut off the volume control.
Turn both integral supply stops outward until they contact the
stop bracket.
Open and close the volume control (not shown) to relieve
pressure that has built up in the valve.
Remove the head nut from the assembly by turning the head nut
counterclockwise.
Reinstall the detent collar. Be sure the spring is resting on top of
the detent collar.
Reinstall the head nut onto the assembly until hand-tight. Do not
overtighten.
Reattach the removal clip to the head nut. The tab on the removal
clip should be facing inward.
Turn both integral supply stops inward.
Verify the temperature. Repeat the above steps if necessary.
Proceed to the "Shower Temperature Adjustment" section of this
guide.
