PLANNING YOUR INSTALLATION
When planning your installation, use the drawings
below and on page 5 to guide you. There are many
variables to consider as you plan. Some of these are:
_" the water filter housing inlet and outlet internal
threads are 3/8" NPT.
_," existing plumbing type (copper, threaded, etc.)
and nominal size (1/4", 3/8" etc.)
_" tools you have, and your plumbing skills
_" cost of materials needed
_" space available for installing the filter housing
Sears has an optional kit available to make installing
the water filter housing easier (see below and page
5). These are:
:k Installation Kit, Sears Item No. 42-38445 - In-
cludes 3/8" fittings and tubing.
Make a simple sketch of your proposed installation,
and a list of plumbing materials you will need. Ob-
tain every thing you need before starting the installa-
tion. Be sure you have the tools required.
