3DEALKALIZER OPERATION SUMMARY
3.1 Description
The Dealkalizer reduces the alkalinity in the feed water present as bicarbonate, carbonate,
or hydroxide to prevent high pH water from interfering with the performance of the carbon
filtration and the reverse osmosis system.
3.2 How It Works
Dealkalizers are basically anion water softeners (standard softeners use cation resin rather
than anion resin). The Dealkalizer reduces the alkalinity of the water through an ion
exchange process. The water passes over resin beads charged with chloride ions. The resin
beads attract the bicarbonate, carbonate, and hydroxide ions in the water and exchange
them with chloride ions. The supply of chloride ions is progressively depleted until reaching
a state of exhaustion. Regeneration of the dealkalizer replenishes the supply of chloride ions
and eliminates the previously removed bicarbonate, carbonate, and hydroxide ions.
NOTE: Install Water Softeners before any Dealkalizer or an Organic Scavenger.

3.4 Monitoring
1. Verify at the beginning of each day that the control head timer is set to the correct
time and correct day, record that this verification was done. This prevents the
system from inadvertently regenerating during clinical operation, which would cause
the RO to shut down via the interlock mechanism.
2. AAMI requires testing twice daily, once at the beginning of the day and once at the
end of the day. Test and record the pH level of the water at the dealkalizer inlet and
outlet to ensure that the pH level is lower at outlet. This testing must be done at
least once per day at the beginning and end of the treatment day.
3. Monitor the brine tank daily to ensure that the salt level fills at least half of the tank.
Salt added to the brine tank must be clean pellet type, cube, or solar salt only. Do
not use rock salt.
4. High pH results at the dealkalizer outlet may indicate a lack of salt in the brine tank
resulting in insufficient regeneration, dealkalizer not going into or exiting
regeneration degeneration in the chemical properties of the resin, or an open bypass
valve. Notify the medical director if high pH results are obtained at the dealkalizer
outlet.

4SYSTEM INSTALLATION
4.1 Installation Requirements
Water Pressure
A minimum 20 pounds per square inch of inlet water pressure, is required for the
regeneration
valve to effectively operate
Electrical Facilities
An uninterrupted alternating current (A/C) supply is required. Make sure:
Voltage supply is compatible with unit before installation.
Current supply is always hot and cannot be turned off with another switch.
Location of Dealkalizer
Locate the Dealkalizer close to a clean working drain after the water softener and prior to
carbon tanks. Then, connect according to the local plumbing codes.
Bypass Valves
Always provide for installation of a bypass valve, if unit is not equipped with one.
CAUTION:
Minimum water pressure 20 psig.
Maximum water pressure 125 psig.
Minimum water temperature 34°F.
Maximum water temperature 110°F.
Ambient temperature 34° to 122°F (1° to 50°C).
Disconnect all power sources before servicing.
Always operate with cover in place.
NOTE: This product should be installed by qualified personnel. Comply with all plumbing &
electrical codes when installing this product.

10 98-0181 Rev B
4.2 Installation Instructions
1. Always install devices as shown on the AmeriWater Piping and Instrumentation
Drawing (P&ID) provided with the water purification system. Failure to do so may
adulterate the marketing clearance on the device and void all AmeriWater
warranties.
2. Place the tank where you want to install the unit. Verify that the tank is level and on
a firm base, and that the tank label and control face are visible. Here are some
additional things to consider when choosing an installation location.
a) Is there sufficient space available to mount the Bypass Header?
b) Will the hoses reach from the Bypass Header to the control valve connections?
c) Will the control valve power cord reach the 120‐Volt GFI receptacle?
d) Will the control valve drain hose reach the drain?
e) Is there sufficient space available to set the brine tank?
f) Will the brine line tubing reach from the control head to the brine tank?
g) Are there any obstructions that interfere with reading the labels, reading the
controller screen, programming the controller, or performing maintenance?
3. After the tank is loaded with media it may be too difficult to reposition. Perform the
following steps to establish the final location of the control valve in relation to the
tank body [ The "front" of the tank may not be where you think it is ].
a) Install the control valve and sealing o‐ring into the tank.
b) Tighten to the same torque you expect to use after the media is loaded.
c) Mark the junction of the control valve to the tank body with a small ink pen mark
or mark from a marker pen or a piece of tape.
d) Remove the control valve and sealing o‐ring from the tank, being careful not to
disturb the alignment marks just made.
e) Reposition the tank now if needed to keep the control valve in the desired
position.
4. Place the distibutor basket and riser pipe into the empty tank. Measure down from
the tank opening to the top of the distributor basket. Pull the tape measure back up
1" to 2". Record this measurement [ This is done because a visual inspection will not
be possible once water is added ].
5. Fill the tank approximately 1/4 of the way up the tank side with water to protect the

11 98-0181 Rev B
distributor from falling media during media loading.
6. Cover, plug, or otherwise protect the open end of the riser pipe from the media
being loaded.
7. Load the gravel media. While loading periodically take measurements from the tank
opening to the top of the gravel media layer. Stop loading when the measurement
taken previously is reached. Refer to the loading charts provided for the approximate
amount of gravel to be used for your particular model number.
8. Load the dealkalizer resin media. Refer to the loading charts provided for the amount
required to be used for your particular model number.
9. Remove the plug or cover from the riser pipe and clean the tank opening threads and
surrounding surface of media loading debris.
10. Clean & lubricate the control valve o‐ring seals and any surfaces they will seal
against.
11. Install the control valve into the tank opening threads. Tighten to the mark
established previously in this procedure.
12. Connect all plumbing in accordance to your local plumbing codes. The dealkalizer
should be installed using the appropriate AmeriWater Bypass Header. This allows the
device to be bypassed for service.
13. Make plumbing connections to the Clack V125DTH valve head.
14. Calibrate the pH meter. With meter in measurement mode, immerse electrode and
Matching Pin (if available) in pH 7.01 buffer solution, shake briefly and wait for
reading to stabilize. Adjust the CAL trimmer until “7.0 pH” is displayed on the LCD.
15. If you notice a spike in alkalinity, check the pH of water with a hand held pH meter.
If the hand held meter and the Dealkalizer meter do not match, recalibrate the
Dealkalizer pH meter.

4.3 Start-up Instructions
1. Completely program the control valve or verify it has been programmed correctly [
The "Fill" cycle has to be programmed to support the brine tank testing].
2. Perform these steps to flush pipe cutting debris & other debris from the piping prior
to putting water into the control valve and vessel [Debris can enter the control valve
and cause an easily avoided failure ].
a) Place the Bypass Header valves into the "Bypassed" position [Allows any
possible debris to bypass the control head].
b) Turn on the main water supply feeding the Bypass Header.
c) Open a sample port downstream of the Bypass Header and let the water run
for a few minutes or until the system is free of foreign material resulting from
installation. Close the sample port when the water runs clean [Obtain the
highest flow possible for the best flushing results].
d) Place the Bypass Header valves into the "Service" position.
3. Plug the control valve into a 120‐Volt GFI receptacle [Necessary to reposition the
control valve].
4. On the Bypass Header, shut the dealkalizer inlet valve and dealkalizer outlet valve
[Uncontrolled water flow into the control valve is undesirable at this time].
5. On the control valve, cycle the valve into the "Backwash" position. Once the control
valve is in the "Backwash" position, unplug the control valve from the 120‐Volt GFI
receptacle [Backwash position is to vent the air, unplugging the control valve allows
for unlimited time to complete the filling and venting].
6. The control valve and vessel are now ready to be filled with water and the air
vented. Slowly open the dealkalizer inlet valve until it is approximately 25% open
[Filling too quickly before the resin is fully hydrated can result in resin "floating" out
and to the drain].
7. The control valve and vessel are now slowly filling with water and the air vented thru
the drain hose. When air stops venting thru the drain hose and water exits instead,
slowly shut the dealkalizer inlet valve.
8. Continuing with a backwash at this point could result in a loss of resin. To avoid this
a rapid (fast or final) rinse is needed [This will help to fully hydrate the resin and
remove the resin "color throw"].
a) Plug the control valve into a 120‐Volt GFI receptacle.

14 98-0181 Rev B
b) On the control valve, cycle the valve into the "Rinse" position. Once the
control valve is in the "Rinse" position, unplug the control valve from the 120‐
Volt receptacle [Rinse position is to send the water thru the resin and out the
drain, unplugging the control valve allows for unlimited time to complete the
color throw rinseout].
c) Slowly open the dealkalizer inlet valve until it is fully open. Water will be
flowing rapidly from the drain hose. This water will be discolored from the
new resin [Flow rate will be controlled by the Backwash Flow Control].
d) When the water from the drain hose becomes clear, slowly shut the
dealkalizer inlet valve [A white background helps with this such as a wall,
sheet of paper, or foam cup].
e) Plug the control valve into a 120‐Volt GFI receptacle [Necessary to reposition
the control valve].
9. Brine tank cycles & levels are checked as follows :
a) On the control valve, cycle the valve into the "Service" position. Once the
control valve is in the "Service" position, cycle the valve thru the "Backwash"
position and other positions until it is in the "Fill" position [The control valve
cannot be made to advance in the reverse direction to get to a previous cycle.
It has to be forward advanced out of the programming mode then back into
the programming mode and forward advanced into the desired cycle].
b) On the Bypass Header, open the dealkalizer inlet valve and dealkalizer outlet
valve.
c) Allow the brine tank to fill for the programmed "Fill" time. The control valve
will advance to the "Service" position at the end of this time [This step can be
shortened but the "Fill" must be allowed to continue uninterrupted until the
entire air check screened intake area is covered. After that the brine line can
be disconnected to measure the flow rate, multiply that flow rate by the
number of minutes left of "Fill" time, and that amount of gallons of water
added by bucket after first stopping the "Fill" into the brine tank].
d) If a grid plate is used, verify there is at least 1" of water above the grid plate
[This is the minimum depth of water needed to properly dissolve the "dry"
salt stored above the grid plate].
e) Using a tape measure, record the depth of water in the brine tank or measure
down from the top of the tank to the top of the water surface.
f) On the control valve, cycle the valve into the "Brine" position. Once the
control valve is in the "Brine" position, verify that water is being suctioned
from the brine tank by periodically measuring the water surface position until

15 98-0181 Rev B
a difference is noted from the previously recorded measurement
[Disconnecting the brine line and checking for vacuum will not verify the air
check assembly in the brine well is functioning].
g) Allow the water to continue being suctioned out until the level drops to about
the midpoint of the air check screened intake area. This is located inside the
brine well. Verify the water level does not continue to fall below this point
[This check verifies the air check will not allow air to be suctioned into the
control valve].
10. Allow the control valve to run automatically thru the rest of the steps until it returns
to the "Service" position. Or advance the control head to the "Fill" position and then
let it return to "Service" automatically [This allows the brine tank to refill with water
in preparation for normal operation].
11. Fill the brine tank with salt any time during the previous step to between 50 and
100% full [The brine tank has to be maintained with a supply of salt for normal
operation].
12. Set the Setpoint on the Dealkalizer pH Monitor.
a) Press the "SET" key. The display will show the default or previously adjusted
value, together with the "SET" indication.
b) Using a small screwdriver, adjust the "SET" trimmer until the desired setpoint
value is displayed.
c) After 1 minute, the meter automatically returns to the normal mode, or press
the "MEAS" key.
13. Operating the Dealkalizer pH Monitor.
a) Before proceeding make sure that the monitor has been calibrated
[Calibration is part of the Installation Instructions].
b) Before proceeding make sure that the monitor setpoint valve has been
adjusted [Setpoint adjustment is part of the Start-up Instructions].
c) The LCD will show the pH value. The LED indicator will light up green, when
the Monitor is in the measurement mode.
14. Pre-Treatment lock-out must be set up as shown in Section 8.
