1. Do I still use the same amount of soap in the dishwasher and clothes washer and showers now that I have a water softener? No,
the Water Quality Association states soft water can save up to 55% on detergent use. Start with using half the amount of detergent previ-
ously used, this can be adjusted up or down based on preference.
2. What is the health impact of drinking soft water? The sodium added to water by a softener is a non-issue most of the time, even for
people on a sodium-restricted diet. One could soften up to 75 grains per gallon water with sodium chloride and still be well within the US
Food and Drug Administration’s guidelines for a “Low Sodium” beverage. People on a sodium-restricted diet should consult their physician.
3. Should I use soft water for my plants? Some plants may be sensitive to even minute amounts of sodium. Suggest using hard water for
watering plants, often a kitchen cold faucet is plumbed for hard water or the outside faucets are usually plumbed for hard water. If not, you
can place your softener on bypass and ll water containers at the closest sink. Water from a reverse osmosis system can always be used
to water plants.
4. Will water spots disappear now that I have soft water? Water spots caused by hardness scale will disappear with a functioning water
softener. However, other natural minerals dissolved in the water may cause spotting in high enough concentrations. These mineral spots
will be much easier to wipe away compared to hardness spotting.
5. Will soft water cause my water or ice cubes to look or taste different? Most people can tell the difference in taste between hard and
soft water, it is a personal preference. Ice cubes will appear the same, they may look cloudy due to air in water or dissolved minerals, and
this will not change because they are made with softened water. A reverse osmosis drinking water system will provide clearer ice cubes.

SOFT WATER BASICS
Hardness
Excess amounts of calcium and magnesium in water produce hardness. A water softener removes the majority of calcium and
magnesium to produce softened water.
Hardness is measured in terms of grains. (This grain weight is derived from the average weight of a dry grain of wheat.) When your
water is tested the grain hardness is calculated and expressed as grains per gallon (gpg). This calculation, as well as the number of
people in your household will help determine what type and size of water softener will most efciently soften your water.
Your water softener contains an ion exchange media (often called resin) which removes the hardness from water as it ows
through each softener tank. Eventually so much hardness collects on the exchange media that the softener can no longer soften the
water in that tank. At this point it is considered "exhausted". The twin alternating function automatically switches to the standby tank
and regeneration occurs immediately on the exhausted tank.
Figure 1
Regeneration
To regenerate the exchange media, it must be rinsed with a brine (salt) solution. This removes the hardness from the exchange
media and replaces it with sodium. The exchange media is then ready to remove hardness from water. The hardness minerals and
excess brine solution are rinsed down the drain. The ProMate-7.1 regenerates with softened water from the online tank.
During the regeneration cycle the softening media is also backwashed. This reversing of the normal ow of water serves to remove
sediment which may have accumulated during the softening process due to the ltering action of the exchange media. Backwashing
also loosens and uffs up the bed of exchange media to insure that during regeneration the brine solution will come into contact with all
the media.
Maintenance of Your Conditioner
Salt: Salt to a softener is what gasoline is to a car. Not only must a softener have salt, but it should be the proper type to insure
efcient recharging of the unit. Ask your dealer what type of salt may best suit your needs. Always have an adequate supply of salt on
hand. Check the salt level of your brine tank every couple of weeks initially to determine how much salt you use - this will depend on how
much water you use. As a rule of thumb, with 20 gpg hard water, about a 1/2 lb. of salt per person per day is used. In other words, a
family of four uses 60 lbs. of salt a month. Fill the tank approximately three-fourths full, with a minimum of 12” of salt. If your household
does not use much water, do not ll your salt keeper over 1/2 full, salt bridging may occur in the brine tank. This may result in hard water
due to ineffective regeneration. DO NOT USE Block Salt when the ProMate-7.0 control is programmed with a brine tank prell. Block
salt does not dissolve quickly enough to provide a good regeneration.
Cleaning Salt Tank: The salt tank may require periodic cleaning. Inspect the salt tank at least once a year for buildup of insoluble
materials. It is recommended to periodically clean the salt tank no matter what kind of salt you are using. See page 8, Maintenance #2
for details on cleaning.
REMEMBER: Salt is the fuel to run your water conditioner. Buy the best clean salt available.

Water Pressure: A minimum of 25 pounds of water pressure
(psi) is required for regeneration. Maximum 100 psi.
Water Quality: On rural water supplies there is often a problem
with sand or sediment in the water. (This problem occasionally
occurs in public water supplies.) If the water is not ltered before
being softened, the sand and sediment may plug up the water
softener restricting the ow through the resin bed. This problem
often requires rebedding of the mineral tank. Note: Well and/or
pump problems aecting the operation of the softener are repairs
that are not covered under warranty. To prevent these unneces-
sary, and expensive repairs that are not covered under warranty,
we recommend the installation of an in-line lter system ahead
of a water softener.
Electrical: A continuous 110 volt 60 cycle current supply is
required. Make certain the current supply is uninterrupted and
cannot be turned o with another switch. All electrical connec-
tions must be connected per local codes. Surge protection is
recommended with all electric controls.
Existing Plumbing: Existing plumbing must be free from lime
and iron build-up. Piping that is built-up heavily with lime and/or
iron must be replaced. If piping is blocked with iron, additional
equipment must be installed ahead of the water conditioner to
correct the problem.
Drain Line: The softener should be located close to a drain.
Avoid overhead drain lines if possible to prevent back pressure
on the brine injector. Overhead drains are not to exceed 8 feet
above the oor and no more than 20 feet in length. The pipe
size for the drain line should be a minimum of 3/4”. Backwash
ow rates in excess of 7 gpm or length in excess of 20’ require
1” drain line.
Bypass Valves: Always provide for the installation of a bypass
valve.
Softening: It is recommended that the conditioner be installed
to soften both the hot and cold water supply. A separate hard
water faucet may be plumbed for drinking purposes if desired.
Outside faucets should be left on hard water.
Caution: Water temperature is not to exceed 110°F; the condi-
tioner cannot be subject to freezing conditions, or to a vacuum
due to loss of pressure (such as a water main break).
PRE-INSTALLATION CHECK LIST
(All electrical & plumbing should be done in accordance to all local codes)
OPERATING CONDITIONS
Your water conditioner has been designed to adequately
handle up to 100 grains per gallon of hardness as well as up to
2 ppm of ferrous bicarbonate iron. This is iron that is dissolved
in water and not visible to the eye in a freshly drawn sample.
After standing in contact with air, the ferrous iron will become
oxidized to the ferric state and start to precipitate as a reddish
brown oc. It can be seen and may cause discolored water. In
order for your softener to remove the iron, air (oxygen) must be
kept from coming in contact with water until after it has been
passed through the water conditioner. In some cases, additional
equipment may be required to treat water supplies having special
characteristics, such as: ferric hydroxide iron, iron bacteria, low
pH, taste and odors, etc. If any question should exist, contact
your dealer.
This water softener is not intended to be used for treating
water that is microbiologically unsafe or of unknown qual-
ity without adequate disinfection before or after treatment.
WATER SOFTENER DISINFECTION
The construction materials of your water softener will not support
bacterial growth nor will these materials contaminate a water
supply. However, the normal conditions existing during shipping,
storage, and installation indicate the advisability of disinfecting
a softener after installation, before the softener is used to treat
potable water. In addition, during normal use a softener may
become fouled with organic matter or in some cases, with bac-
teria from the water supply.
Therefore, every water softener should be disinfected after
installation, some will require periodic disinfection during their
normal life. You have two choices for disinfection as follows:
A. SODIUM HYPOCHLORITE (household bleach)
5.25% SODIUM HYPOCHLORITE solutions are available
under such trade names such as Clorox, Linco, Bo Peep,
White Sail and Eagle Brand Bleach. If stronger solutions are
used, such as those sold for commercial laundries, adjust
the dosage accordingly.
1. Dosage:
a. Softening resin; 1.2 uid ounce per cubic foot of
resin.
2. Add the required amount of hypochlorite solution to the
brine well of the brine tank.
a. Proceed with the normal regeneration. Press REGEN
and allow the water softener to go through a normal
regeneration.
B. EPA and NSF approved Sani-System by Pro Products.
