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 cabinet. A clean pellet,
solar, or cube-type 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. A water treatment specialist
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 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 your electricity be off for any reason,
check your 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, the appropriate filter can
eliminate this problem.
6. The appliance shall be disinfected after
installation or service with 5.25% sodium
hypochlorite, which is the active ingredient in
household chlorine bleach. To disinfect the
appliance, add 4 fluid ounces (0.12 L) of
chlorine bleach solution to the brine well of the
brine cabinet. The brine cabinet 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 Bypass mode also 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.
10. Adhere to all operational, maintenance, and
placement requirements.
11. Inspect and clean the brine cabinet and air
check/draw tube assembly annually or when
sediment is present in the brine cabinet.

AquaMaster®Owner’s Manual 1/21/2021 6
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, consider pre-treating 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.
The appropriate AquaMaster®Water Filter can address these water shortcomings. Contact your water
treatment specialist for assistance in obtaining appropriate pre-treatment before the water supply enters this
appliance.
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. See Maximum Ferrous Iron in
Specifications.
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. The hardness setting increases by 4 grains per gallon for every 1 mg/L (ppm) of ferrous iron
programmed into the controller.
Water Characteristics—The conditioner requires a pH of 7 or above to function properly. An iron test to
determine iron levels is also necessary. An Acid Neutralizing Filter may be necessary if pH levels are below 7.
Water Hardness—Double check the hardness of the water with the test strips provided to verify that your
appliance is the right one for the job. If the result of your hardness test strip
reaches the test maximum of 25 grains per gallon (427.5 ppm), mix 1 cup (0.25
liters) tap water with 1 cup (0.25 liters) distilled water. Then retest this mixture for
hardness. Multiply your reading by 2 and use this setting number.
•Model AMP5000 will condition water for up to 70 grains of hardness per
gallon (1,197 mg/L).
•Model AMP5100 will condition water for up to 90 grains of hardness per
gallon (1,539 mg/L).
•Model AMP5500is FOR MUNICIPALLY-SUPPLIED WATER without iron. Model AMP5500 will condition
water up to 35 grains of hardness per gallon (600 mg/L).
Water Pressure—Not less than 20 psi or greater than 120 psi (1.4–8.4 bar) constant. If water pressure
exceeds 70 psi (4.8 bar), a pressure regulator is recommended.*
Water Supply Flow Rate—A minimum of 2 gallons (7.6 liters) for AMP5000 & AMP5100, or minimum of 3
gallons (11.4 liters) for AMP5500 per minute or equal to the backwash flow rate of the particular model 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° or greater than 120°F (6°–49°C).
*Applies to US plumbing codes. Check the plumbing codes of your country.

of untreated water for watering plants, shrubs, or lawns.
The bypass is located on the main control valve. See Figure 9. To engage the bypass, turn the knob to the
Bypass position. The appliance will be bypassed and all water to the home is raw, untreated water. To prevent
untreated water from entering the home, water should not be used inside the home when the appliance is in
Bypass mode. Ensure that the appliance is returned to Service mode when the appliance is repaired or the use
of untreated water is complete by turning the knob to Service.
To blend hardness back into the water using the bypass, turn the knob slightly from the Service position toward
the Bypass position.
Figure 7: Bypass Valve
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.
B. Wrap the threads three times with 1/2-inch wide PTFE tape. Place each consecutive wrap on top of the
previous wrap.
C. To prevent tearing of the tape, use PTFE 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.
D. Use a union with a threaded connection to facilitate repair of potential leaks in soldered joints.
E. 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.
F. Ensure that the copper tube is long enough to allow fitting clearance with the valve cover in place.
G. Turn the fitting counterclockwise until you feel the threads engage and then tighten to prevent cross
threading. Do NOT overtighten the fittings.
Caution: Do NOT allow heat from the torch to transfer to the plastic valve component, which could be
damaged.

AquaMaster®Owner’s Manual 1/21/2021 14
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. 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.

Power Clean
(5000 and 5100
only)
Activates/deactivates the powerClean™ feature, which is a service/maintenance step for water
supplies that have an excessive amount of iron. “powerClean™” will display when this feature is
activated. The appliance will regenerate every other day with five pounds (2.3 kg) 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.
Use this feature every six months as a part of your routine maintenance procedure to ensure a long
service life for your water treatment appliance

Setting the Controller
Step 13 Determine the Controller Setting Number
H. For municipal water, call the water department to
determine the hardness and pH of your water supply.
For well water, use the hardness test strips provided
with your appliance, or have a sample of your
untreated water tested by a water testing laboratory.
9. Test Strips—Follow the instructions on the test
strips. If the color on your test strip is
between two readings, use the higher number.
Compare the colors as soon as you remove them
from your water. This number gives the hardness
in grains per gallon and parts per million (mg/L).
10.Testing Laboratory—To ensure proper settings,
have a sample of your untreated water tested for
iron and pH. To find a facility to test your water
sample, check your Yellow Pages under Water
Analysis or Water Testing or contact the company
below to conduct a test for you.
National Testing Laboratories, Ltd.
1-800-458-3330

11.If the pH is below seven and you have a 700 or
900 unit, call the HelpLine listed in General
Information.
Use the following example to determine the controller
setting.

Step 14 Enter Your Setting Number Into the Controller
I. Press and hold the Set button for about 5 seconds until “25” displays.
Press the Change button until the display matches your compensated number. Once you
pass “70” (models 700 and 950) or “90” (model 900), the display will reset to “03.”
Press Set to save the hardness setting number.
To recheck the hardness setting number, hold down the Set button for about 5 seconds.
Note: Refer to Specifications for the maximum water hardness that your appliance can
handle.
Your controller is now set.

Advanced Customer Settings
Most customers will want to use the factory default settings, so no changes are necessary. However, you can
reset the controller settings if the factory default settings are not suitable for your needs.
Note: Be sure to check that the Time of Day is correct.
Set High Capacity or High Efficiency
Your appliance can be programmed for High Capacity (HC) or High Efficiency (HE).
•High Capacity means the appliance will regenerate less often, but use more salt.
•High Efficiency will make the appliance regenerate more often and use less salt. This is the default. The
High Efficiency setting meets or exceeds the requirement some states have for salt efficiency.
To Enter Advanced Customer Settings Mode
A. Press and hold the Set and Change buttons at the same time for 3 seconds. The display should show
only the controller type. After 3 seconds, the entire screen is lit for a half second, and then “HC”
displays.
a. Press Change to toggle the digit display between “HC” and “HE.”
b. When the desired value is displayed, press Set.
Note: HE ensures the appliance chooses salt settings that get 4,000 grains per pound (570
grams/kg) of salt for each regeneration or better. This choice meets or exceeds the requirement
some states currently have in regards to salt efficiency.
Note: All models are equipped with patented capacity guard.
Once in HC or HE, you can set the mode, hours to next regeneration, gallons or liters, time format, time of day,
and time of regeneration.
Step 15 Set Mode
Display reads “Demand Mode.”
To Change Mode
J. Press Change.
−Delay Mode allows regeneration at a specific time (for example, at 2 a.m. when less
water is typically being used).
−Demand Mode triggers a regeneration as soon as softening capacity is exhausted. This
is the default.
When the desired mode is displayed, press Set.
Step 16 Set 96 Hours Until Regeneration
Display reads “96 Hours.”
To Change Setting
K. Press Change to turn Off. If “96 Hours” is selected, the appliance will work no more than
4 days without a regeneration. Default is for “96 Hours” to be On.
Note: If there is iron in your water, select this option. If you are using model 950, on most
municipal water supplies, turn this option Off.
When the desired setting is displayed, press Set.
