Before You Start

HOW THE WHIRLPOOL® ANTI-SCALE

SYSTEM WORKS

Hard water forms “scale” deposits in plumbing.

These deposits are composed of calcium carbonate

(CaCO3) and magnesium carbonate (MgCO3). As

scale builds up over time, it can clog plumbing and

coat the heating element in your water heater,

significantly reducing its efficiency and life.

Unlike a traditional water softener which uses ion

exchange media to remove calcium and magnesium

ions from the water, the Whirlpool® Anti-Scale System

converts them into a crystalline form that is less prone

to forming scale. This system does not require water

for backwashing and does not discharge water to the

drain.

Since the Whirlpool® Anti-Scale System does not

require the addition of salt or chemicals, it is practically

maintenance free. The system may benefit from

having anti-scale media added every few years,

based on your water use and water conditions.

INSPECT SHIPMENT

The parts required to install the Whirlpool® Anti-Scale

System are included with the unit. Thoroughly check

the system for possible shipping damage and parts

loss. Remove and discard (or recycle) all packing

materials.

WHERE TO INSTALL THE SYSTEM

=

Place the system as close as possible to the pres-

sure tank (well system) or water meter (city water).

=

Connect the system to the main water supply pipe

upstream of the water heater. Do not run hot water

through the system. The temperature of water

passing through the system must not be above

120°F (49°C). Damage caused by hot water is not

covered by the warranty.

=

Do not install the system where freezing

temperatures could occur. Damage caused by

freezing is not covered by the warranty.

=

Keep outside faucets on untreated water to

conserve media capacity.

=

Put the system in a place water damage is least

likely to occur if a leak develops. The manufacturer

will not repair or pay for water damage.

=

If installing in an outside location, you must take

the steps necessary to assure the system is as

effectively sheltered from the elements, contamina-

tion, vandalism, etc., as when installed indoors.

=

Avoid installing in direct sunlight. Excessive sun

heat may cause distortion or other damage to

non-metallic parts.

TOOLS, PIPE & FITTINGS,

OTHER MATERIALS YOU WILL NEED

=

Plastic inlet and outlet fittings included with the

system allow water flow equivalent to 1 inch

(2.54 cm) nominal pipe. To maintain full valve flow,

1" (2.54 cm) pipes to and from the system fittings

are recommended. Do not reduce the pipes to less

than 3/4" (1.9 cm) size.

=

Use copper, brass or PEX plastic pipe and fittings.

=

ALWAYS install the included bypass valve, or

3 shut-off valves. Bypass valves let you turn off

water to the system for repairs if needed, but still

have water available to the house pipes.

PLAN HOW YOU WILL INSTALL THE SYSTEM

You must first decide how to run in and out pipes to

the system. Look at the house main water pipe at the

point where you will connect the system. Is the pipe

soldered copper, glued plastic, or threaded brass/

galvanized? What is the pipe size?

Now look at the typical installation illustrations on

page 5. Use them as a guide when planning your

particular installation. Be sure to direct incoming,

untreated water to the “UPFLOW INLET” port.
