Operation
To adjust and fine-tune showerhead water pressure, rotate the
comfort-control lever between its vertical “LOW” position and
horizontal “FULL FLOW” position. Ideal water pressure is be-
tween 40-80 psi, but will flow in a range from 20 to 120 psi.
Note: The comfort control lever is NOT a shutoff valve. When
turned to the lowest position, the showerhead continues to flow
at 1 /

to 1 1 /
