maximum clockwise position. If field adjustments are needed proceed as follows:
To DECREASE
temperature,
turn the control shaft
slightly to the left
COUNTERCLOCKWISE
.
To INCREASE
temperature, proceed as follows: With the control knob ALREADY TURNED TO ITS MAXIMUM
CLOCKWISE POSITION, locate the small, slotted ADJUSTMENT SCREW inside the hollow shaft. By using a
narrow blade screwdriver
engage the slotted adjustment screw and turn it an 1/8 of a turn slowly to
the left (counterclockwise
) until a click is heard and the Green Ready Light goes OFF.
NOTE: Measure the water temperature at the head with the spray head removed in order to capture a solid
stream of hot water. DO NOT forget to REPLACE spray head afterwards.
In HIGH ALTITUDE locations, (5000 ft. above sea level) the thermostat setting will have to be lowered to
prevent boiling.
