WATER TREATMENT FILTER CARTRIDGES (cont.)
(5) Phosphate Cartridge: This cartridge adds pure
food grade phosphate into the water supply. PhosĆ
phates coat the insides of pipes, plumbing fixtures, the
water heater, etc. The coating keeps slightly acid (6.8
- 6.9 pH) and corrosive water away from the surfaces
to help prevent rusting, staining and scaling.
Note: Acid water, below 6.8 pH, requires other water
conditioning. Have a sample of your water analyzed
by a qualified water testing laboratory and get their
recommendation for treatment. You can get a free waĆ
ter analysis at your nearest Sears store.
When adding phosphates to your water system, locate
the water filter housing to treat:
- THE ENTIRE HOUSE SUPPLY


, OR
- BOTH HOT AND COLD SOFT WATER
,
OR
- HOT WATERONLY

Note: If no other water conditioning units are installed,
always treat the entire house supply

PLANNING YOUR INSTALLATION
When planning your installation, first read the precedĆ
ing filter cartridge information and decide where to loĆ
cate the water filter housing. Then, use the drawings
on page 5 to guide you. There are many variables to
consider as you plan. Some of these are:
n The water filter housing inlet and outlet internal
threads are 3/4" NPT.
n existing plumbing type (copper, threaded, etc.) and
nominal size (1/2", 3/4" etc.)
n tools you have, and your plumbing skills
n cost of materials needed
n space available for installing the filter housing
Sears has optional kits available to make installing the
water filter housing easier (see page 5). These are:
L Installation Kit, Sears Item No. 42-34346 - Includes
fittings to fit nominal 1/2" (5/8" O.D.) or 3/4" (7/8"
O.D.) copper.
L Installation Kit, Sears Item No. 42-34347 - Includes
3/4" and 3/8" fittings, and 3/8" tubing to connect to a
single faucet.
L Mounting Bracket, Sears Item No. 42-34348 - priĆ
marily, for undersink installation
Make a simple sketch of your proposed installation,
and a list of plumbing materials you will need. Obtain
everything you need before starting the installation.
Be sure you have the tools required.
