:Place the softener as close as possible to the
pressure tank (well system) or water meter (city
water).
:Placethe softenerascloseaspossibletoafloor
drain, or other acceptable drain point (laundry
tub, sump, standpipe, etc.).
:Connect the softener to the main water supply
pipe BEFORE or AHEAD OF the water heater.
DO NOT RUN HOT WATER THROUGH THE
SOFTENER. Temperature of water passing
through the softener must be less than 120EF
(49EC).
:Keep outside faucets on hard water to save soft
water and salt.

could freeze. )UHH]H GDPDJH LV QRW FRYHUHG

:If installing in an outside location, you must take
the steps necessary to assure the softener,
installation plumbing, wiring, etc., are as well
protected from the elements, contamination,
vandalism, etc., as when installed indoors.
:Keep the softener out of direct sunlight. The
sun’s heat will melt plastic parts.

up to the softener inlet and outlet.
0Use copper, brass, or galvanized pipe and fittings.
Some codes may also allow CPVC plastic pipe.
0ALWAYS install a bypass valve or valves. Either
usetheoptionalvalve (included with somemodels),
or 3 shut-off valves. Bypass valves let you turn off
water to the softener for repairs if needed, but still
have water in the house pipes.
0Drain hose (3/8” or 7/16” inside diameter) is need-
ed for valve and salttank drains. You can buygood
quality, thick-wall, flexible hose at most hardware
stores.
0If a rigid valve drain is needed, to comply with
plumbingcodes,youcanbuythepartsneeded(see
page 8) to connect a 1/2 in. copper tubing drain.
0Nugget orpellet water softener salt is needed to fill
the brine tank (see page 9 and 16).

You must first decide howto run in and out pipes to
the softener. Look at the house main water pipe at
the point where you will connect the softener. Is the
pipesolderedcopper,gluedplastic,orthreadedgal-
vanized ? What is the pipe size?
Now look at the typical installation illustration on
page 6.Use itas a guide when planning yourpartic-
ular installation. Be sure to direct raw, hard water
to the softener valve inlet fitting. The valve is
marked IN and OUT.
