US Water Systems classifies each softener according to the actual resin capacity. However, this is not the
regeneration capacity. The regeneration capacity will be lower than the actual resin capacity. This is due to
the resin ’ s regeneration salt curve. For example:
A 53,000 grain unit would require 30 lbs of salt during regeneration if the capacity was set to the actual resin
capacity ( 53,000 grains ) . If the unit is set at 37,000 grains it can be regenerated using only 10 lbs of salt.
The unit is much more efficient when it is set using the proper salt curve capacity and salt dosage levels. So
you can see that to get the final 16,000 grains from a 53,000 grain unit the salt usage will more than double.
Please use the chart below when setting you softener. This will ensure efficiency and longevity of your unit.
 Maximum Water Temperature = 110°F (43°C)
 Maximum Operating Pressure = 100
PSIG (689 kPa)
 Voltage = 110 volts standard
 Pipe Size = 3/4”
 At the stated service flow rates, the pres-
sure drop through these devices will not
exceed 15 psig.
 Changing salt settings from factory setting
may require changing injector sizes to
achieve stated capacities.
 The manufacturer reserves the right to make
product improvements which may deviate from
the specifications and descriptions stated herein,
without obligation to change previously manufac-
tured products or to note the change.

How Your Water Conditioner Works
The principle behind water softening is simple chemistry. A water softener contains resin beads which hold electrically
charged ions. When hard water passes through the softener, calcium and magnesium ions are attracted to the charged resin
beads. It's the resulting removal of calcium and magnesium ions that produces soft water.
This valve is controlled with simple, user-friendly electronics displayed on a large LCD screen. The main page displays the
current date and time. In addition, the main page also shows key valve information and statistics including: current capacity
setting, volume remaining, date of last regeneration, current flow rate, and peak flow rate.

will be queued to the next pre-set regeneration time (2:00 a.m.).
Control Operation During A Power Failure
In the event of power failure, the valve will keep track of the time and day for 48 hours. The programmed settings are stored in
a non-volatile memory and will not be lost during a power failure.
If power fails while the unit is in regeneration, the valve will move to the service position from the point it is at once power is
restored. However, since the unit did not complete its regeneration, it will queue another regeneration at the next scheduled
regeneration time.
If the valve misses a scheduled regeneration due to a power failure, it will queue a regeneration at the next regeneration time
once power is restored.

Matrixx Tank Installation Instructions
WATER PRESSURE: A minimum of 20 pounds of water pressure is required for regeneration valve to operate effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Note: Other voltages are availa-
ble. Please make sure your voltage supply is compatible with your unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily
with lime and/or iron should be replaced.
LOCATION OF MATRIXX TANK AND DRAIN: The Infusion tank should be located close to a drain to prevent air breaks and
back flow.
CAUTION: Water pressure is not to exceed 80 psi, water temperature is not to exceed 110°F (43°C), and the unit cannot be subjected to
freezing conditions.
Media Installation
Assembly Instructions
Media Installation (for HTO systems please refer to the Quick Start Guide)
1) Remove the tank from carton.
2) Verify the riser tube is centered in the bottom center of the tank. A flashlight may be necessary.
3) Place a piece of duct tape over the riser tube so no media enters the riser while filling.
4) Make sure the riser is centered to facilitate the valve in-
stallation after installation of the media.
5) Use the Blue Funnel provided, to pour the media into the
tank. Pour it evenly around the hole to ensure it is well dis-
tributed in the tank and pour slow enough, to keep from
plugging the hole.
6) When media is installed move tank side to side to settle the
media.

Use a 3/4” pipe or tubing for backwash flow rates that exceed 7 gpm or length that exceeds 20ft (6 m)
3. Any solder joints near the valve must be done before connecting any piping to the valve. Always leave at least 6" (152
mm) between the valve and joints when soldering pipes that are connected to the valve. Failure to do this could cause
damage to the valve.
4. Chose the plumbing connectors and install them in the bypass valve. Remove the red clip and insert the connector. Re -
install the red clip to secure the connector.
4. Connect the drain line to the valve.
5. Connect the brine line from the valve to the air check / safety elbow. Double check to make sure all connections are as-
sembled correctly and the plastic nut is tight and secure to prevent leaks. Remove the clip from the brine connection on
the valve and push the brine line in the connector. Be sure the line is pushed in completely. Pull on the line to make
sure it is secure. Re-install the clip to lock the fitting.
6. Add water until there is approximately 2" (25 mm) of water above the grid plate. If the tank does not have a grid, add wa-
ter until it is above the air check in the brine tank. Add (2) 50 lb. bags of salt to the brine tank.

Automatic Bypass The regeneration cycle lasts approximately 75 minutes, after which soft water service will be re-
stored. During regeneration, hard water is automatically bypassed for use in the household. Hot
water should be used as little as possible during this time to prevent hard water from filling the wa-
ter heater. This is why automatic regeneration is set for sometime during the night and manual re-
generations should be performed when little or no water will be used in the household.
Safety Float The brine tank is equipped with a safety float which prevents your brine tank from overfilling as a
result of a malfunction such as a power failure.
New Sounds You may notice new sounds as your water softener operates. The regeneration cycle lasts approxi-
mately 2-1/2 hours. During this time, you may hear water running intermittently to the drain.
Manual Bypass In the case of emergency, such as an overflowing brine tank, you can isolate your water softener
from the water supply using the bypass valve located at the back of the control. In normal operation
the bypass is open with the on/off knobs in line with the inlet and outlet pipes. To isolate the soften-
er, simply rotate the knobs counter clockwise until they lock. You can use your water related fix-
tures and appliances as the water supply is bypassing the softener. However, the water you use will
be hard. To resume soft water service, open bypass valve by rotating the knobs clockwise.

Maintenance
Adding Salt Use only crystal water softener salt. Check the salt level monthly. It is important to maintain the salt level
above the water level. To add salt, simply lift the salt lid and add the salt directly into the brine tank.
Be sure the brine well cover is on and fill only to the height of the brine well.
Bridging Humidity or wrong type of salt may create a cavity between the water and the salt. This action, known as
“bridging”, prevents the brine solution from being made, leading to your water supply being hard.
If you suspect salt bridging, carefully pound on the outside of the brine tank or pour some warm water
over the salt to break up the bridge. This should always be followed up by allowing the unit to use up
any remaining salt and then thoroughly cleaning out the brine tank. Allow four hours to produce a brine
solution, then manually regenerate the softener.
Care of Your
Softener To retain the attractive appearance of your new water softener, clean occasionally with mild
soap solution. Do not use abrasive cleaners, ammonia or solvents. Never subject your softener to freezing
or to temperatures above 120°F.
Cleaning the
Injector Assembly Sediment, salt and silt will restrict or clog the injector. A clean water supply and pure salt will
prevent this from happening. The injector assembly is located on the right side of the control
valve. This assembly is easy to clean.

19
Installation, Operation and Maintenance Manual
Matrixx MX-100, MX-150, MX-200 System
Shut off the water supply to your softener and reduce the pressure by opening a cold soft water faucet. Using a screwdriver,
remove the two screws holding the injector cover to the control valve body. Carefully remove the assembly and disassemble
as shown in Figure 6. The injector orifice is removed from the valve body by carefully turning it out with a large screwdriv-
er. Remove the injector throat the same way. Carefully flush all parts including the screen. Use a mild acid such as vinegar
or Pro-Rust Out to clean the small holes in the orifice and throat.
Reassemble using the reverse procedure.
Resin Cleaner An approved resin cleaner must be used on a regular basis if your water supply contains iron. The amount of
resin cleaner and frequency of use is determined by the quantity of iron in your water (consult your local representative or
follow the directions on the resin cleaner package).
