View the Full PDF Version of this owner's manual.
Congratulations on your decision to place your confidence in a superior WaterBoss® water treatment appliance.
Recognized worldwide for built-in quality, dependability, and ease of service, WaterBoss®
appliances represent state-of-the-art in home water treatment.
Important information is contained in this manual which will help you
get the maximum benefit and enjoyment from your particular model.
We
urge you to read this information carefully now and any time a
malfunction may occur. In most cases, these reviews will uncover minor
problems that you can correct yourself, thereby saving you time.
How To Get The Maximum Efficiency From Your Water Softener
1. Fill salt cabinet when water level is above salt level. DO NOT MIX
DIFFERENT TYPES OF SALT. If iron is present in your water, use a salt
with an iron-cleaning additive to help keep resin clean. You may also
use a resin cleaner on a monthly basis in place of salt with cleaning
additives. If iron is not present in your water, a clean pellet, solar
or cube type salt is recommended. The use of rock salt is not
recommended because it contains impurities that can plug up the
injector assembly.
2. You may use a salt substitute (such as potassium chloride) in place
of water conditioner salt. If you start with water conditioner salt,
you can switch to a salt substitute at any time - or vice versa. If
potassium chloride is used in place of nugget or pellet salt, increase
your hardness setting by 12% (multiply by 1.12). Do not use Potassium
Chloride if there is iron in your water.
3. Should
your electricity be turned off for any reason you must reset the time
of day if you programmed your appliance for delayed regeneration.
4. Protect your system from freezing, including drain line.
5. By-pass the appliance when servicing the well, plumbing, or pump.
When work is completed, turn on the nearest cold water tap until water
runs clear before putting appliance back in service. See figures 4 - 5
- 6.
6. Install after the pressure tank.
* Excludes WaterBoss® 550 model.
Checklist Before Installation of Your Water Softener
1. Water Pressure - Not less than 20 psi constant for WaterBoss® water softeners.
2. Double check hardness - of water with test strips provided to verify that your
WaterBoss® is the right water softener for the job.
WaterBoss® 550 FOR MUNICIPALLY-SUPPLIED WATER is for water without iron and up to 25 grains of hardness per gallon.
WaterBoss® 700 for up to 70 grains hardness per gallon.
WaterBoss® 900 for up to 90 grains hardness per gallon.
3. Water Supply Flow Rate - 5 gallons per minute is recommended as minimum.
4. Drain
- Drain appliance to floor drain or washer drain. To prevent
back-siphoning, the installer must provide an adequate air gap or a
siphon break. See figure 1.
5. Electricity
- The transformer supplied is a standard 120 volt, 60 cycle A.C. for
USA or 220 volt, 50 cycle A.C. for outside the USA. See figure 8.
6. Water Quality
- If the water supply contains sulfur, bacteria, iron bacteria,
tannins, algae, oil, acid or other unusual substances, then unless the
system is represented as being capable of treating these contaminants
in the specifications, other special treatment of the water supply must
be used to remove these contaminants before they enter this product.

Cycles
Water
by-passes your water softener during regeneration to allow iron,
sediment, hardness, etc. to be washed down the drain. After
regeneration, WaterBoss® returns to service, providing your home with treated water.
Regeneration cycles:
1. First up-flow backwash. A rapid up-flow of water flushes out the resin bed and
cleans the sediment filter.
2. Brine. Brine is drawn out of the brine cabinet and up through the media tank,
cleaning the resin bed and releasing accumulated hardness and iron.
3. Slow rinse. A slow up-flow rinse process then flushes out the brine, hardness and iron.
4. Second up-flow backwash. This up-flow backwash flushes out any remaining brine solution and sediment from cycle 2.
5. Downflow soft water brine refill. Soft water is directed to the
brine cabinet to prepare the brine for the next regeneration sequence.
6. Return to service. Regeneration is complete and the appliance is returned to normal operation.

Much of your resin could be wasted!

Directional Flow Screen Distribution System
Directs flow evenly through bed for most efficient use.
Installation And Start-Up Procedures
Each WaterBoss® water softener and filter includes water test strips and 8' of
drain line.
1. Placement: Place your WaterBoss®
water softener in desired location. Turn off electricity and water
supply to water heater. Make sure inlet/outlet and drain connections
meet the applicable local codes. Check arrows on valve to be sure water
flows in proper direction. See figures 1, 2, & 3.
CAUTION: DO NOT PLUMB APPLIANCE IN BACKWARD.
2. Drain Line: must be a minimum of 1/2"-5/8” I.D. tubing and should
make the shortest run to a suitable drain. The drain line may be
elevated up to 8 feet from the discharge on the appliance as long as
the water pressure in your system is 40 psi or more. If drain line is
25' or longer, increase drain line to 5/8" I.D. Also, the end of the
drain line must be equal in height or lower than the control
valve. See figure 1. All overhead drains for filter installations must be 3/4” I.D.
3. Flushing: Before placing your WaterBoss®
appliance in service, it is very important to flush the cold water
lines of any debris. Turn on water supply, open the nearest cold water
tap and let the water run for 2 to 3 minutes until the water flows
clear. Then put the by-pass in the Service position. See figures 4
through 6.
4. Check Leaks. Close faucet
and check for leaks. If leaks are found, turn off main water supply and
open the nearest cold water faucet to depressurize lines. Close faucet
to eliminate siphoning action. Repair leaks. Turn on water supply and
electricity to water heater. Place the bypass valve in the Service
position. See figure 6.
5. Connect
Overflow Line. The overflow line must end at a drain that is at least
3" lower than the bottom of the overflow fitting. It is a gravity line
and cannot be run overhead. See figure 7.
6. Complete The Installation. Open a cold water tap and allow the
appliance to flush for 20 minutes or until approximately 72 gallons has
passed through the appliance per NSF requirements.
7. Plug In Transformer. See figure 8.
8. Setting Number. For WaterBoss® 700, 900, and 550
for municipally-supplied water, determine your controller setting
number. Do not guess at the setting; continued water quality problems
or damage to the unit could result.
Municipal
water - call your local water company to determine your water hardness
in grains per gallon. This will be your setting number. Or, follow the
instructions on the hardness test strip provided with your WaterBoss® 550 to determine your hardness reading. This will be your setting number.
Well water - follow the instructions on the pH and hardness test strips provided with your WaterBoss® water softener to determine the pH and hardness of your water.
Iron adjustment:
if pH is 7 or above and you know your water has iron, add 15 to your
hardness reading in grains per gallon and enter the result as your
setting #.
Example: hardness in grains
per gallon from test strip is 20 + 15 = 35 = setting #. This is a
temporary setting until you have an accurate water test.
If the result of your hardness test strip reaches the test maximum of
25 grains per gallon, mix 1 cup tap water with 1 cup distilled water,
then retest for hardness. Multiply your reading x 2 and use this number
as your setting number. If the test strip result is still 25 grains per
gallon, call your HelpLine. Or, contact the company below to test for
hardness, iron and pH.

If you feel you have an abnormal amount of iron, push the powerClean® button for models WaterBoss® 700 and WaterBoss® 900 only. Also, be sure to use salt with an iron-cleaning additive. Be aware that WaterBoss® 550 for municipally-supplied water is not designed to treat water with iron. If pH is below 7, Call your HelpLine.
9. Adding Water & Salt. Be sure to remove any packaging or
installation materials before adding salt. Next, add not more than 2
gallons of water to the brine cabinet. Then add salt to the brine
cabinet, wait 2 hours then push the immediate recharge button and hold
for 5 seconds. A regeneration cycle will begin and continue as follows:
WaterBoss® 900 , 53 minutes; WaterBoss® 550 for municipally-supplied water, 31 minutes; and WaterBoss®
700
38 minutes. After the first regeneration, your softener will
automatically refill the correct amount of water in the brine cabinet.
See figure 10.
10. Refill Salt when the
salt level drops below the water level in the brine cabinet. Always
keep salt above water level. See figure 10
CAUTION! Failure to install, operate and maintain your water treatment
system as instructed will VOID the product limited warranty.
NOTE! Make sure the Owner's Limited warranty Card is filled in and mailed
within 30 days of installation. NO POSTAGE REQUIRED.
Setting The 4 Button Controller
DEMAND REGENERATION
You won’t have to worry about vacation settings or extra guests because
the controller measures water usage and regenerates based on need. The
appliance will regenerate using only the necessary amount of water and
salt. If power has been turned off, your appliance will retain
programmed settings indefinitely. See figure 9.
1) ENTERING YOUR HARDNESS SETTING
See page 14 for determining your setting number. The water hardness
setting number shown in the digital readout will increase 1 grain each
time you push the "SET" button. After 70 grains for WaterBoss® 700 (90 grains for WaterBoss® 900 and 25 grains for WaterBoss® 550) the read-out will return to 1, and continue to count up from 1 until the display number matches the hardness
number. After 5 seconds the display will change to show "gallons remaining (x 100). To recheck the hardness, touch "SET."
2) GALLONS REMAINING
After setting water hardness, gallons remaining until the next
automatic regeneration is shown in the digital display. NOTE: Gallons
remaining are in hundreds. 12=1,200 gallons
3) RECHARGE/REGENERATION STATUS
Regeneration cycle numbers are shown during regeneration. The read-out
will flash with the cycle number. The flashing regeneration numbers are:
(C1) First Backwash
(C2) Brine/Slow Rinse
(C3) Second Backwash
(C4) Brine Refill
(HO) Service
See pages 11 and 12 for cycle descriptions and illustrations
To quickly advance through the regeneration cycles, press and hold the
Regenerate button for 2 seconds. Wait for the cycle to begin, after 20
seconds press and hold the Regenerate button until the cycle number
changes (about 2 seconds.) Each cycle can be advanced in this manner.
4) waterMizer
The waterMizer® wheel will turn whenever water is being used. See figure 9.
5) REGENERATE
To start an immediate regeneration, press The Regenerate button and
hold for 3 seconds. The Regenerate button is used when starting your
water conditioner, to start an immediate regeneration, or to restore
capacity if you have run out of salt. If your WaterBoss® has run out of salt, you may not have soft water available. Remove the salt lid and add salt. Wait two hours, then press the
"REGENERATE" button and hold for 3 seconds. See figure 9.
6) POWERCLEAN
The powerClean feature is a service/maintenance step for water supplies
that have an excessive amount of iron. Activating this feature is a
simple push of the powerClean button on the controller. PowerClean will
appear in the display when this feature is activated. The appliance
will regenerate every other day with five pounds of salt. Leave the
powerClean feature on for a minimum of two weeks. The frequent
regeneration will eliminate iron buildup in the resin bed. The use
of salt with an iron cleaning agent or iron out cleaner is recommended
for continuous use as a preventive measure against iron fouling of the
resin bed. To deactivate this feature, simply press the powerClean
button. Use this feature every six months as a part of your routine
maintenance procedure to insure a long service life for your water
treatment appliance. See figure 9.
HARDNESS SETTINGS
1. Hold down SET for 3 seconds to enter basic customer settings mode.
2. "Set Hardness" and a default hardness number is now displayed.
Pressing and releasing the CHANGE button will increase the hardness
setting # by one. As a short cut, pressing and releasing the POWER
CLEAN button will advance the display by 10. But the CHANGE button
alone can be used to advance the display one digit at a time to the
correct number. If "Gallons x100" was selected, 01 = 100 gallons. If
"Liters x 1000" was selected, 01 = 1,000 liters. Pressing and releasing
SET will save the hardness number and put the unit into operation. The
unit is now ready for use as recommended. To fine-tune the programming
further:
ADVANCED CUSTOMER SETTINGS:
Your WaterBoss®
can be programmed for High Capacity (HC) or High Efficiency (HE). High
Capacity means the unit will regenerate less often, but use more salt.
High Efficiency will make the unit regenerate more often and use less
salt. See Specification/Capacity Chart, pg. 30.
1. Hold down SET and CHANGE for 3 seconds to enter advanced customer
settings mode. While SET and CHANGE are being held down, the display
should show only the controller type (see chart below). After the 3
seconds, the entire screen is lit for a half second, and then "HC" will
appear.
2. Pressing and releasing the
CHANGE button will toggle the digit display between "HC" and "HE".
Pressing and releasing the SET button will advance programming to the
next step. Default is "HC".
3. The
controller will now display "Demand Mode." Each press of the CHANGE
button will switch between "Demand Mode" and "Delayed Mode".
Delayed
Mode allows regeneration at a specific time (e.g. at 2am when less
water is being used.) Demand Mode triggers a regeneration as soon as
softening capacity is exhausted.
Pressing and releasing the SET button will advance programming to the next step. Default is"Demand Mode".
4. "96 Hours" is now displayed. Pressing and releasing the CHANGE button
will toggle this on and off.
If
"96 Hours" is selected, the unit will work no more than 4 days without
a regeneration. Note: If there is iron in your water, select this
option.
Pressing and releasing the SET button will advance programming to the next step. Default is for "96 Hours" to be ON.
5. "Gallons X100" is now displayed. Pressing and releasing the CHANGE
button will toggle between "Gallons X100" and "Liters X1000". Choosing
gallons sets the controller to English units, and choosing liters sets
it to metric units. Pressing and releasing the SET button will advance
programming to the next step.
6. If
"Gallons" was chosen "12" is now displayed. If "Liters" was chosen "24"
is displayed. Pressing and releasing the CHANGE button will toggle
between "24" and "12". This controls the selection of a 12-hour (AM/PM)
or 24-hour clock. If 24-hour, 00=midnight. Default is "12".
7. "Set Time" and "12" is now lit. To set the time, press and hold the
CHANGE button to advance the numerical display, and switch from "PM" to
"AM" if appropriate. Note: set the time to the nearest hour. Pressing
and releasing the SET button will save the time displayed and advance
to the next menu. Pressing and releasing the SET button will advance
programming to the next step. Default is 12 PM.
8. "Set Reg. Time" and "02" is now displayed. To set the regeneration
time, press and release the CHANGE button to advance the numerical
display. Pressing and releasing the SET button will save the "regen.
time" displayed and put the unit into operation. Default is 2 AM.
