Read All
Caution: Read and follow the information in this
manual to minimize the risk of electric shock or per-
!
sonal injury.
Important: If you are unsure about installing your Watts
water softener, contact a Watts representative or consult a professional plumber.
Important This system must be installed in compliance
with applicable state, province and local codes, law,
and regulations.
READ Instructions Before Using
• Before beginning installation, read these instructions completely.
Then obtain all the materials and tools needed for installation.
NOTE: Failure to install the system correctly voids the warranty.
• Perform installation according to state, province and local plumbing
codes.
Use only lead-free solder and flux for sweat-solder connections,
as required by state, province and federal codes.
• Handle all components of the system with care. Do not drop, drag
or turn components upside down.
• Be sure the floor under the water softening system is clean and
level.
• The system uses 24 volt-60Hz electrical power. Always use the
transformer supplied.
Plug transformer into an indoor 120 VAC, grounded outlet.
Properly ground the system to conform with all codes and ordi-
nances.
• Install the system in a protected area. Be sure electric outlet and
transformer do not come in contact with water. See Where to
Install the Softener, in the installation section of the manual.
Do not attempt to treat water over 110°F (43°C) with the sys-
tem. Always connect the system to the main water supply pipe
before water heater.
Do not expose the system to freezing temperatures. Water
freezing in the system causes equipment damage.
Do not install in direct sunlight. Ultraviolet rays from the sun may
cause damage.
• Minimum inlet water pressure is 20 psi. Maximum inlet water pressure is 125 psi. Use a pressure reducing valve if necessary.
• Sodium used in the water softening process should be considered
as part of your overall dietary salt intake. Contact physician if you
are on a low sodium diet.
• Use clean water softening salts only, at least 99.5% pure. Failure
to use the correct salt may create a health hazard or maintenance
problems.
Use nugget, pellet or coarse solar salts.
Do not use rock, block, granulated or ice cream making salts.
• Always keep the salt lid in place unless servicing the unit or replenishing salt.
Caution:
• Do not use with water that is microbiologically
!
unsafe or of unknown quality.
• Test the water periodically to verify that the
system is performing satisfactorily.
• Discard small parts remaining after the installation.

Where to Install the Softener
Consider the following points when determining where to install the
water softener:
• Place the system as close as possible to a sewer drain.
• Do not install the softener where it would block access to the water
heater, or access to the main water shutoff, water meter, or electrical panels.
• Keep outside faucets on hard water to save soft water and salt.
• Install the softener in a place where water damage is least likely to
occur if a leak develops.
• A 120VAC electrical outlet is needed to plug in the transformer. If
the outlet is remote (up to 100 feet), use 18 gauge wire to connect.
• Always connect the system to the main water supply pipe before
the water heater.
• Install the system where it will not be subject to temperatures
outside of the limits stated in the Specification section or to direct
sunlight.
Determine Hardness Setting
Municipal Water
It is recommended that you call your local water company to determine your water hardness in grains per gallon and iron in mg/l (or
ppm).
Well Water
It is recommended that you have your water tested professionally for
accurate hardness and iron content.

14. Fully open two (2) cold (soft) water faucets near the water softener.
15. Fully open the house main water shutoff valve. Observe a steady
flow from both faucets.
16. Slowly, turn bypass valve back to the "service" position. Keep
soft water faucets open.
NOTE: If the water appears cloudy or has a slight yellow color,
allow it to run for several more minutes until it runs clear.
17. After the air is purged and the
water runs clear, open a HOT
water faucet until all air is expelled,
then close.
18. Close all water faucets.
19. Check plumbing work for leaks
and fix immediately if any are
found.
20. Connect electrical power by plugging the power cord into a
(120 VAC) outlet.
21. Set the time of day. Press and hold either the Up or Down buttons until the programming icon replaces the service icon and
the parameter display reads TD. Adjust the displayed time with
the Up and Down buttons. When the desired time is set, press
the Extra Cycle button to resume normal operation. The unit will
also return to normal operation after 5 seconds if no buttons are
pressed.
Figure 6
d) Turn ON the gas or electric supply to the water heater.
e) Manually initiate a regeneration by pressing and holding the
“Extra Cycle” button on the front of the controller for approximately 5 seconds (see figure 5). Release the “Extra Cycle”
when you hear the valve start to cycle. The controller will
automatically step the valve through the proper cycles. This
will take approximately two hours.
23. It will be necessary to enter the controller master programming
function (see separate ProFlo SXT service manual included
with system) and program the hardness setting to match the
compensated feed water hardness of the water supply. The
compensated hardness is:
Feed water hardness in grains per gallon times the compensation
factor plus 2 grains for each ppm of iron rounded up to the next
whole number.
Figure 5
22. Although the material used in the manufacturing of this water
softener will not contaminate your water supply, the softener
could become contaminated during shipment and installation.
The media inside the resin tank may also have become disturbed
during shipping. The following procedure will help re-position the
media, sanitize, flush and condition your water softener:
a) Remove the brine tank cover and add salt to the tank. Use
only nugget, pellet, or coarse solar salt designed for water
softener use with a purity of 99.5% or higher.
b) Add three gallons of water to the brine tank for 32K, 45K,
& 60K systems, and add 5 gallons of water for 90K & 120K
systems.
c) Remove the brine well cover. Pour 1-1/2 ounces of common
household bleach into the brine well and replace the cover
(see figure 6).
FeeD Water HarDness compensatIon Factor
1 – 20 grains 1.1
21 – 40 grains 1.2
41 – 70 grains 1.3
71 – 100 grains 1.4
> 100 grains 1.5
Example: Feed water hardness = 17 grains, iron = 0.5 ppm
The compensated hardness is 17 x 1.1 + 1 = 19.7 so the hardness
setting would be 20 grains.
Note: This step can be performed at the same time as step 21
above if desired.

Control Start-up Procedures
Control start-up, flushing/conditioning and programming procedures may be found in the control service manual included with your
system.
Control Service Manual: ProFlo SXT Downflow Brining Service
Manual
Softener Operation
As water enters the softener, it passes over a resin bed in the mineral
tank. The resin consists of tiny beads of plastic called styrene. These
beads attract and hold sodium ions and exchange the sodium for
hardness ions when encountered. Over time, the resin becomes
saturated with hardness ions and no longer removes hardness
materials. The softener goes into a "regeneration" to flush hardness
materials to the drain and refresh the resin with sodium. Regeneration is typically programmed to take place in the middle of the night
when little or no water is in use.
Service
Cleaning Iron Out of the
Water Softening System
The system is designed to remove minerals like calcium and magnesium from household water. Periodic resin bed cleaning is recommended if your iron rating is high. Clean the bed at least every six
months, or more if iron appears in the soft water between cleanings.
Contact the system installer for this service.
Checking for a Salt Bridge
A hard crust or "Salt Bridge" can form in the lower half of the salt
storage tank. This can be deceiving because the tank will appear to
have plenty of salt, but underneath, salt has hardened and when the
system regenerates, water cannot quite reach this level to be made
into brine (water and salt).
Regeneration consists of four cycles:
1. Brine Draw / Slow Rinse Position
Brine Draw: The process in which brine is drawn out of the brine
cabinet and passed through the resin in a downward direction. This
rinses the resin and large amounts of sodium ions replace the hardness ions accumulated during service. Slow Rinse: After brine is
completely transferred from the brine cabinet into the resin tank the
brine valve closes. Water replaces any remaining brine from the resin,
flushing hardness ions removed from the resin to drain.
2. Backwash Position
Backwash is a rapid upward flow of water that loosens the resin bed
and flushes iron particles, dirt and sediments filtered in the bed out
to the drain.
3. Fast Rinse Position
Fast Rinse is a fast flow of water down through the resin tank that
follows a Backwash. This flushes all remaining brine from the tank
and packs the resin bed for softening efficiency.
4. Brine Fill
Brine is water saturated with large amounts of salt (sodium chloride).
During brine fill, water flows into the salt storage area after each
regeneration and dissolves salt. During the regeneration process,
hardness ions on the resin beads are replaced or exchanged for
sodium ions from the brine solution.
5. Service
When the softener is In Service water is flowing through the system
and removing hardness minerals from your water.
Breaking a Salt Bridge
Take a wooden broom handle and carefully push it down into the
salt, working it up and down. If the tool strikes a hard object (be sure
it's not the bottom or sides of the tank), it's probably a salt bridge.
Carefully break the bridge with the broom handle. Do not pound on
the walls of the tank.
NOTE: Salt bridges are typically caused by high humidity or
using the wrong kind of salt. In humid areas it is best to fill with
less salt, more often. Use only nugget, pellet or coarse solar
salt with a purity of 99.5% or higher. DO NOT use rock, block,
granulated, and ice cream-making salts, or salt with iron-removing additives.

Cleaning the Injector and Screen
1) Turn off water supply to conditioner:
a) If the conditioner installation has a “three valve” by-pass
system, first open the valve in the bypass line, then close the
valves at the conditioner inlet and outlet.
b) If the conditioner has an integral by-pass valve, put it in the
by-pass position.
c) If there is only a shutoff valve near the conditioner inlet, close it.
2) Relieve water pressure in the conditioner by stepping the control
into the backwash position momentarily. Return the control to
the service position.
3) Unplug electrical cord from outlet.
4) Remove the two injector cap mounting screws.
5) To replace injector and screen.
a) Pull the screen and injector throat/nozzle assembly out of the
valve body.
b) Insert a new injector throat/nozzle assembly, be sure they are
sealed tightly. Install a new screen.
c) Apply silicone lubricant to new injector cap seal.
6) Replace injector cap with two mounting screws.
7) Tighten screws.
8) Return by-pass or inlet valving to normal service position. Water
pressure should now be applied to the conditioner, and any bypass line shutoff.
9) Check for leaks at all seal areas. Check the drain seal with the
control in the backwash position.
10) Plug electrical cord into outlet.
11) Set time of day and cycle the control valve manually to assure
proper function. Make sure control valve is returned to the service position.
12) Make sure there is enough salt in the brine tank.
13) Start regeneration cycle manually if water is hard.
