Introduction
The next-ScaleStop system provides protection from scale formation throughout the home. The
ScaleStop system can be installed at the point of entry to treat your entire home, both hot and cold
water, or it can be located directly before a water heater or other device (e.g. sauna, etc) that requires
protection from hard water.
ScaleStop reduces or eliminates scale formation on internal and external plumbing surfaces as well
as reducing spotting and streaking normally associated with hard water.
ScaleStop prevents scale by transforming the normal dissolved hardness minerals into undissolved
crystal micro-particles. These crystals stay suspended in the water and have a greatly reduced ability
to react and attach to surfaces like dissolved hardness does. Therefore the problem of internal build-
up of scale in pipes, water heaters and on fixtures and glass is greatly reduced.
ScaleStop is not a water softener – Low or phosphate-free cleaning products are recommended to
achieve optimum results. Modern surfactant or detergent based, liquid soaps are preferred over old-
fashioned caustic solid soaps.
Unlike softened water, Scalestop treated water maintains the beneficial essential mineral content of
your water and is safe to drink.

Notes to the Installer.
The ScaleStop system differs from a conventional softener or media filter in a number of key re-
spects.

An important note about iron, manganese and copper in the water supply.
Iron and Manganese
Just as with conventional water softening media, ScaleStop needs to be protected from excess levels
PGDFSUBJONFUBMTUIBUDBOFBTJMZDPBUUIFBDUJWFTVSGBDFSFEVDJOHJUTFGGFDUJWFOFTTPWFSUJNF1VCMJD
water supplies rarely, if ever, present a problem, but if the water supply is from a private well confirm
that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L and 0.05 mg/L respectively.
Copper should be less than 1.3 mg/L.
Copper
Copper usually originates from new copper plumbing upstream of the ScaleStop system. If this condi-
tion exists, we recommend waiting 3-4 weeks before placing the system in operation. This will allow
the copper surfaces to be fully flushed and develop a natural protective surface. To further minimize
any problem with excess copper the plumbers should be advised to avoid applying excess flux on the

standard. Once the plumbing connections are complete, place the ScaleStop system in bypass prior
to following the startup procedure and flush the plumbing for at least 10 minutes.

A note to the homeowner
Your ScaleStop system will improve the properties of water throughout your home. Here
are some things to expect and some recommendations for maximizing the benefits and
ZPVSFOKPZNFOUPG4DBMF4UPQ
Sinks and fixtures - reduced spotting. If water is al-
lowed to evaporate off a surface, small spots may be left
behind. If wiped off frequently, the spotting should not
require any more than a wet cloth or sponge to remove.
No harsh chemical should be required as with typical hard
water spotting.
Dishwasher-Spotting on dishes and on the surface
of the dishwasher should be greatly reduced. We
recommend that you immediately reduce the amount of
dishwashing detergent by approximately 50% as com-
pared to hard water use. Dishwashing detergents low in
phosphates are highly recommended as they are better
for the environment and phosphates can cause spotting.
The use of a rinse aid may be advised.
Shower doors and tiles- should have reduced spot-
ting. When water evaporates off a surface, small spots
may be left behind. These spots should be easy to re-
move with a damp cloth or sponge. In very hard water
areas treating the shower glass with Rain-X® 2 in 1 glass
cleaner, or equivalent, will further reduce cleaning re-
quirements.
In the bath you should notice that soaps and shampoos
lather more than with un-treated water. Soaps and sham-
poos will also rinse off much easier and faster than they
would with traditional soft water. We recommend the use
of modern soaps for the best results.

crease in the calcium in the water because scaleStop is removing old scale deposits from
your pipes.
Good practices:
If your dishwasher is severely coated with scale at the time of installation, we recommend that
you purchase a product like Jet-Dry Dishwasher cleaner to accelerate the cleaning. After this
initial cleaning ScaleStop should keep it clean.
We also recommend that you drain your water heater tank. This should be done 30 to 60
days after ScaleStop is installed, and again in one year. This is a good practice that can dra-
