Install Fittings and Mounting Bracket
Instructions are for installing fittings supplied with the filter
(on some models) or the WHKIT onto 3/4
″
copper plumbing.
If the unit is to be installed on any other type of tubing (plastic,
PVC, galvanized), different hardware must be purchased. See
instructions with additional hardware purchased, or consult
a qualified plumber.
Apply about 12
″
of Teflon tape, in a clockwise
direction, to the pipe threads of each fitting.

use joint compound on any parts.
Use the bracket as a template to find the
two screw locations. Wood screws are provided. If mounted
onto other surface, use appropriate hardware.
Drill a 3/16
″
hole on each marked screw location (optional),
then drive the two wood screws until about 1/4
″
of thread
is left. Ensure at least one screw is anchored into wall stud.
Assemble a fitting through the mounting bracket hole to
the inlet and outlet of the head. Start each fitting by hand
to make sure they don’t cross thread. Use a 1
