8. Install the Sprayhead
Using a 5/32" hex wrench, secure the sprayhead to the waterway
with the two hex screws. Do not overtighten.
Verify that the sprayhead sits squarely within the escutcheon and
tilts freely up and down.
Place the nozzle membrane over the sprayhead, aligning the long
edge of the membrane with the ribs.
NOTE: For optimum performance, ensure that the membrane is
applied evenly.
Applying pressure evenly, press the membrane seal into the
sprayhead groove.
