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.
1 | Apply about 12″ of Teflon tape, in a clockwise |
direction, to the pipe threads of each fitting. | |
| DO NOT use joint compound on any parts. |
2 | Teflon tape |
Use the bracket as a template to find the | |
| two screw locations. Wood screws are provided. If mounted |
| onto other surface, use appropriate hardware. |
3 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.
4 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 11⁄8″ wrench to tighten fittings firmly. DO NOT OVERTIGHTEN.
