Depending on the manufacturing plant, you may have one of two of the following fill
valves:
For Type A Fill Valve:
Refer to the water level (WL) setting marked on
the inner wall of the tank. Allow the water to fill
the tank. Turn the adjustment screw clockwise
in the (+) direction to increase the water level
height (see Illustration 1). Turn the adjustment
screw counter-clockwise in the (-) direction
to decrease the water level height. Flush the
toilet to verify the correct water level. Adjust as
necessary.
For Type B Fill Valve:
There are no water level adjustments. The fill
valve has been preset at the factory.
