3WATER SOFTENER OPERATION SUMMARY
3.1 Description
The Water Softener removes calcium and magnesium (hardness) from the water to prevent
these contaminants from being deposited onto the surface of the RO membranes, which
may irreversibly damage the membranes.
3.2 How it Works
Water Softeners remove calcium and magnesium ions from the water through an ion
exchange process. The water passes over resin beads charged with sodium ions. The resin
beads attract the calcium and magnesium ions in the water and exchange them with sodium
ions. The supply of sodium ions is progressively depleted until reaching a state of
exhaustion. Regeneration of the softener replenishes the supply of sodium ions and
eliminates the previously removed calcium and magnesium 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 of day and record that this verification was done. This prevents
inadvertent regeneration during clinical operation, which would cause the RO
to shut down via the interlock mechanism.
2. Test and record the hardness level of the water at the softener outlet to
ensure that the hardness level is less than or equal to one grain per gallon
(GPG). This testing must be done at least once per day at the end of the
treatment day. Recording of the hardness level must be done after 15
minutes of operation.
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. Monitor and record the pressure drop across the softener daily. Notify the
medical director if the delta pressure is > 10 PSI above established. High
delta pressure may cause improper operation of some of the downstream
water purification components.
5. Periodically check pre-treatment lockout.
6. Monitor brine tank maintenance.
NOTE: Hard water results at the softener outlet may indicate a lack of salt in the brine tank,
degeneration in the chemical properties of the resin, or an open bypass valve. Notify the
Supervisor in charge, if hard water results are obtained at the softener outlet.

4SYSTEM INSTALLATION
4.1 Installation Requirements
Water Pressure
A minimum of 20 psi inlet water pressure is required for the regeneration valve to operate
effectively.
Electrical Facilities
An uninterrupted alternating current 120VAC (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 Softener and Drain
Locate the softener close to a clean working drain and connect according to 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.

4.2 Installation Instructions
1. Install before Dealkalizer or Organic Scavenger.
2. 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.
3. 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?
4. 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.
5. 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).

11 98-0180 Rev C
6. Fill the tank approximately 1/4 of the way up the tank side with water to protect the
distributor from falling media during media loading.
7. Cover, plug, or otherwise protect the open end of the riser pipe from the media
being loaded.
8. 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.
9. Load the softener resin media. Refer to the loading charts provided for the amount
required to be used for your particular model number.
10. Remove the plug or cover from the riser pipe and clean the tank opening threads and
surrounding surface of media loading debris.
11. Clean & lubricate the control valve o‐ring seals and any surfaces they will seal
against.
12. Install the control valve into the tank opening threads. Tighten to the mark
established previously in this procedure.
13. Connect all plumbing in accordance to your local plumbing codes. The softener
should be installed using the appropriate AmeriWater Bypass Header. This allows the
device to be bypassed for service.
14. Make plumbing connections to the Clack V125DTH valve head.

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 softener inlet valve and softener 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 softener 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 softener 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 98-0180 Rev C
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 softener 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 softener
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 softener inlet valve and softener 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 98-0180 Rev C
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. Pre‐Treatment lock‐out must be set up as shown in Section 8.
