Getting Maximum Efficiency from the Appliance
To achieve the maximum benefit and performance
from this appliance, familiarize yourself with this
manual and the appliance.
1. The salt level should always be at least 1/3 full.
Refill the salt when the level drops below the
water level in the brine tank. A resin cleaner
can be used on a monthly basis. Clean white
pellet salt, cube-style salt, or solar salt is
recommended. Do not use rock salt.
Caution: Do not mix different types of salt.
2. You may use a salt substitute (such as
potassium chloride) in place of water
conditioner salt. An independent dealer should
be contacted before a switch is made to a salt
substitute. If potassium chloride is used in
place of salt, the technician must select the
potassium chloride option during the
programming of the controller. See Service
Settings.
Caution: Do not use potassium chloride if
there is iron and/or manganese in the water.
3. Should the electricity be off for any reason,
check the controller for the correct time and
reset as necessary. See Customer Settings.
4. Program the appliance to regenerate at a time
when the water is not being used. If there is
more than one appliance, allow two hours
between each regeneration.
5. If dirt, sand, or large particles are present in the
water supply, pre-treat with the appropriate
filter.
6. The appliance may be disinfected with 5.25%
sodium hypochlorite, which is the active
ingredient in household chlorine bleach. To
disinfect the appliance, add 4.0 fluid ounces
(120 mL) of chlorine bleach solution to the brine
well of the brine tank. The brine tank should
have water in it. Start a manual regeneration.
7. Protect the appliance, including the drain line,
from freezing.
8. The bypass valve (located on the main control
valve) enables you to bypass the appliance if
any work is being performed on the appliance,
well pump, or plumbing. See Bypass Valve.
Use the Bypass mode for watering plants or
lawns with untreated water.
9. Before putting the appliance back in service
after work has been performed, turn on the
nearest cold water tap until water runs clear.

Checklist Before Installation
Refer to this checklist before installation.
Water Quality—If the water supply contains sand, sulfur, bacteria, iron bacteria, tannins, algae, oil, acid, or
other unusual substances, pre-treat the water to remove these contaminants before the water supply enters the
appliance, unless the appliance is represented as being capable of treating these contaminants in its
specifications.
Iron—A common problem found in many water supplies is iron. It is important to know what type of and how
much iron is in the water supply.
Iron Type
Description
Ferrous Iron*
(sometimes called clear
water or dissolved iron)
Only type of iron that can be treated with a water softener
Ferric Iron
Insoluble and the particles can eventually foul a resin bed. It should be filtered out before
the water reaches the softener
Organic Iron or Bacterial
Iron
Attached to other organic compounds in the water. Additional treatment is needed to
remove this type of iron
Colloidal Iron
Not dissolved, yet stays in suspension. A softener cannot remove this type of iron
* If the water supply contains ferrous iron, a commercially available resin bed cleaner should be used every six months. Follow the
instructions on the container. You should also increase the water hardness setting by 5 grains per gallon (86 mg/L) for every
1 ppm (mg/L) of ferrous iron.
Water Characteristics—The 5100 Water Softeners require a pH of 7 or above to function properly. An iron test
to determine iron levels is also necessary.
Water Hardness—Double check the hardness of water to verify that the appliance is right for the job. See
Water Conditioner Specifications.
Water Pressure—Not less than 20 psi (1.4 bar) or greater than 120 psi (8.3 bar) constant. If water pressure
exceeds 70 psi (4.8 bar), a pressure regulator is recommended.
Water Supply Flow Rate—A minimum of 2.4 gallons (9.1 L) per minute is recommended. For the purposes of
plumbing sizing, only the rated service flow rate and corresponding pressure loss may be used. Prolonged
operation of a water conditioner at flow rates exceeding the tested service flow rate may compromise
performance.
Water Temperature—Not less than 40°F (4°C) or greater than 120°F (49°C).
Drain—Drain the appliance to an appropriate drain, such as a floor drain or washer drain that will comply with
all local and state plumbing codes. To prevent back-siphoning, provide an adequate air gap or a siphon break.
See Installation Steps and Start-Up Procedures.
Electricity—The transformer supplied is for a standard 115 volt, 60-cycle AC outlet for locations in North
America or 220 volt, 50-cycle AC outlet for locations outside North America.

Operating Modes
The appliance has two operating modes: Timer mode and Demand Delayed mode. Both modes are equipped
with Capacity Guard®, which ensures that a supply of conditioned water will be available even with excessive
water usage.
Mode 1—Timer Mode
When the appliance is in Timer mode, it will regenerate based on the frequency that is set, for example every
day or up to every 12 days. The time of regeneration can be set.
Mode 2—Demand Delayed Mode
When the appliance is in Demand Delayed mode, it will regenerate based on the actual water usage and the
total capacity of the appliance. The time that the regeneration takes place can be set, for example 2:00 AM.
Should the total capacity be depleted before the set regeneration time, a forced regeneration will occur.
72–96 Hour Regeneration
If this value is set to Yes, the appliance will be forced to regenerate every 72–96 hours unless a regeneration
based on water usage occurs within the time interval. The value should always be set to Yes if iron is present in
the water.

Optional Plumbing Procedures
This section provides information on plumbing with copper fittings and with plastic pipe.
Hard Plumbing the Bypass With Copper Fittings
Do not use Qest fittings for hard plumbing with copper fittings. When preparing the male threaded fittings of the
I/O adapter, use the following guidelines to avoid damage to the plastic pipe threads.
A. Wrap the threads three times with 1/2-inch wide Teflon tape. Place each consecutive wrap on top of
the previous wrap.
B. To prevent tearing of the tape, use Teflon paste on the first two male threads only. The paste lubricates
the tape and fills the small void areas that might exist between the threads. When the joint is complete,
there will be a small bead of sealant at the fitting interface, which indicates a properly joined
connection.
C. Use a union with a threaded connection to facilitate repair of potential leaks in soldered joints.
D. Prepare the copper tail assemblies in advance to enable them to cool prior to final assembly. Advance
preparation and cooling will prevent heat damage to the plastic pipe threads of the adapter.
E. Ensure that the copper tube is at least 4 inch (10 cm) long.
F. Turn the fitting counterclockwise until you feel the threads engage and then tighten to prevent cross
threading. Do NOT over tighten the fittings.
Caution: Do NOT allow heat from the torch to transfer to the plastic valve component, which
could be damaged.

Optional Plumbing Procedures, Cont.
Plastic (PVC/CPVC) Pipe Joining Procedure
To ensure reliable joint integrity when using solvent cement for PVC/CPVC plumbing, follow these
recommendations:
A. Cutting—The pipe must be cut square to allow for the proper interfacing of the pipe end and the fitting
socket bottom. Use a wheel cutter, miter saw, or a ratchet shear for best results.
B. Deburring and Beveling—Use a knife, plastic pipe deburring tool, or a file to remove burrs from the
end of the pipe. Be sure to remove all burrs from the inside as well as the outside of the pipe. Remove
all loose plastic debris since it could clog the injector. All pipe ends should be beveled to permit easier
insertion of the pipe into the fitting. Failure to bevel the pipe end may cause a “wiping” effect in the
fitting where the cement is forced to the end of the fitting socket. This creates a weak joint.
C. Test Dry Fit of the Joint—Tapered fitting sockets are designed so that an interference fit should occur
when the pipe is inserted about one-third to two-thirds of the way into the socket. Occasionally, when
pipe and fitting dimensions are at the tolerance extremes, it will be possible to fully insert dry pipe to the
bottom of the fitting socket. When this happens, a sufficient quantity of cement must be applied to the
joint to fill the gap between the pipe and fitting.
D. Inspection, Cleaning, and Priming—Inspect the inside of the pipe and fitting sockets and remove dirt,
grease, or moisture with a clean dry cloth. If wiping fails to clean the surfaces, use a chemical cleaner.
Check for possible damage such as splits or cracks and replace if necessary. Use purple primer to
penetrate and soften the bonding surfaces of the PVC or CPVC pipe and fittings. Proceed without
hesitation to the cementing procedure while the primed surfaces are still wet.
E. Application of Solvent Cement—Apply the solvent cement evenly and quickly around the outside of
the pipe while the primer is still wet. Apply a light coat of cement evenly around the inside of the fitting
socket. Do not allow excess cement to “puddle” in the fitting. Apply a second coat of cement to the pipe
end.
F. Joint Assembly—Working quickly, insert the pipe into the fitting socket and give a 1/4-turn of the pipe
or fitting while pushing toward the fitting stop. This action will evenly distribute the cement. Do NOT
continue to rotate the pipe or fitting after the stop has been reached. Hold the joint tightly together for
about 15 seconds to prevent the pipe from “creeping” out of the fitting. A good joint will have sufficient
cement to make a small bead all the way around the outside of the fitting hub. The joint should not be
disturbed immediately after the cementing procedure. Allow adequate time for the joint to cure properly.
Exact drying time is hard to predict because of environmental variables. Follow the recommended joint
curing times on the primer and cement container labels.
