The length of time required to alter the characteristics of the lime scale build up is dependent on the
mineral makeup of the water being treated. The mineral makeup of the water can infl uence the operation
of the SCALESWEEPER's electrical fi eld. Before installing any water conditioning system, it is very
important to know the type and concentration of minerals in the water being treated. Have your water
tested by your local or county water department. Table 1 contains the various levels of water hardness (Soft
to Very Hard) as they relate to Parts per Million (PPM) and Grains per Gallon (GPG) of Calcium Carbonate
Equivalent. The maximum hardness level the SCALESWEEPER will effectively work on is 425 PPM or 25 GPG.
Above these levels, the SCALESWEEPER should be used in conjunction with a traditional ion exchange water
softener to remove hardness and condition the water. This allows you to minimize the salt used to remove the
hardness and maintain the cost saving benefi t of the SCALESWEEPER water conditioning system.

A high concentration of iron (soluble and insoluble) causes a disruption and weakening of the SCALESWEEPER's
electrical fi eld, thus reducing its effectiveness on scale reduction. It is recommended that the total iron level in
the water to be treated is less than 0.3 ppm (parts per million). There are iron removal fi lters available that
commonly meet this requirement that can be installed in the water line before the SCALESWEEPER
OPERATION/FUNCTIONALITY
The following timetable should be used to evaluate the operation and functionality of the SCALESWEEPER
during the fi rst 90 days.
DAY 1:
The SCALESWEEPER action immediately starts to loosen existing scale in both the hot and cold water
systems. One should fi nd soaps lathers more easily.
DAY 5 AND ONWARDS:
Scale begins to break down and come off water heater elements (immersion heaters) and tanks. Most particles
are microscopic and will fl ow through your water system, but some small particles may be seen in the water
coming from the hot water tap.
DAY 10 to 16:
It should be noticeably easier to wipe clean ceramic, plastic, glass and metal surfaces. By now the quantity of
bath soap, dish soap, laundry softening agents can be reduced. Scale should have loosened on
faucets, showerheads and frequently used appliances that boil water (such as coffee makers).
DAY 16 AND ONWARD:
Scale should continue to loosen from faucets, showerheads and pipes. With the continuing break down and
reduction of scale from the heating surfaces of water heaters, water should heat up quicker using less energy to
achieve the desired temperature.
AFTER 1 TO 2 MONTHS:
Any scaly crust or stains in toilets or under faucets should be signifi cantly reduced. No new stains or crust should
form. Mold that attaches to scale will begin to disappear from shower curtains and, once cleaned, should not
reappear. Depending on the water hardness in the area, the full effects can take up to 12 weeks, especially if
the system has been heavily scaled up over many years.
