INSTALLATION REQUIREMENTS
Locate a level floor position ahead of piping into water heater for placement.
Unit must be installed at least 10 feet ahead of the inlet to a water heater to prevent damage due to back-up hot
water. DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
Check for distance and proper drain installation (e.g. floor drain, washing machine standpipe). Determine type and
size of piping required for filter connection (e.g. copper, galvanized, PVC plastic).
NOTE: If household plumbing is galvanized and you intend to make the installation with copper (or vice versa),
obtain dielectric unions to prevent dissimilar metal corrosion.
CAUTION: If sweat soldering copper pipe (remember to always use lead free solder and flux), cover yoke and
bypass valve with wet rags to prevent heat damage to connections and control valve. If using PVC or plastic pipe,
primers and solvent cements specifically recommended for use with potable water are required.
NOTE: All plumbing lines not requiring “soft” water should be connected “upstream” of the softener, if installed.

INSTALLATION PROCEDURE
Water Supply Connection and Bypass Valve
To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual Bypass Valve has been installed at the
factory. The Bypass allows raw water to be manually routed around the filter.
1. Position filter at desired location for installation. If a water softener is to be installed, the filter should be
positioned first and then the softener. (See Installation Diagrams.)
2. The filter material is shipped separately from the mineral tank. The tank must be loaded with material after tank
has been placed at the desired location.
A. Remove the control valve by unscrewing from the tank.
B. Place a media funnel in hole on top of tank.
C. Block distributor tube to prevent material from entering the tube while filling.
D. Pour several gallons of water in the tank. (Fill tank about 1/3 full.)
E. Pour in the required filter media. The required quantity and type of media is listed in the filter specifications.
F. After filling the tank with material, use a garden hose or several buckets to fill the tank with water. This will
permit the filtering media to become soaked while preparing the installation and will prevent the control valve
from being plugged with floating material on initial backwash.
G. Remove funnel and clean filter media from tank threads.
H. Remove cap from distributor tube.
I. Replace control valve on mineral tank.
3. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
4. Cut main line and install appropriate elbows and extensions.
CAUTION: Raised arrows located on the sides of control valve body and bypass valve indicate proper direction
of water flow. Install inlet and outlet piping in direction of arrows. It is recommended that a vacuum breaker be
installed on the inlet plumbing.
Drain Line Installation
1. The drain line flow control assembly is pre-assembled for your convenience. Should you choose to hard plumb
the drain line, please remove the barb fitting. The flow control housing can be removed by removing the clip and
pulling straight out on housing.
NOTE: When re-installing the drain line flow control housing, be sure you hear and feel the O-Ring pop into place
before inserting the clip.
2. Install 1/2" I.D. drain line tubing (not included) from hose barb to an open drain. A 4" gap between end of the drain
line and the open drain is required to prevent waste water back-flow. Keep the drain line as short as possible.
An overhead drain line can be used if necessary, but should discharge below the control valve. A siphon trap
(taped loop) at the outlet of the drain line is advisable to keep the drain line full and to assure correct flow during
backwash. Elbows or other fittings must be kept at a bare minimum.
NOTE: Where the drain line is elevated above the control valve or exceeds 20 feet in length, 3/4" I.D. drain line
tubing should be used.

Electrical Connection
1. Connect the power cord and plug power supply into a 120 volt / 60 Hz receptacle.
NOTE: Do not plug into an outlet controlled by a wall
switch or pull chain that could inadvertently be turned off

SYSTEM START-UP PROCEDURE
Service Off Bypass
IMPORTANT NOTE: Tank should be filled with water and media and must have been soaking for at least 1 hour
before initial pressurization.
1. After all plumbing and drain line connections have been made, confirm the Bypass Valve is in
the BYPASS position.
2. Turn main water supply back on and check for leaks.
3. Cycle the control valve to RAPID RINSE. Once the rapid rinse step is reached, leave the OUTLET side of the
Bypass Valve in the CLOSED position. Slowly open the Bypass Valve INLET side to the Service position, allowing
air to escape and water to flow down through mineral tank and out the drain line. Let it continue to run for the
entire rapid rinse step. There may be colored water or media fines during this initial flow.
4. Once the rapid rinse ends, open a cold, treated watertap. Slowly place Bypass into Service. Let water run to home
for several minutes to allow air and any media fines to be released from the lines. Once air is evacuated and water
runs clear, close the tap.
NOTE: Any time media (other than very fine mineral on initial startup) is apparent in the service lines, it usually
indicates one of the following problems:
A.The unit is plumbed in backward allowing the media to be carried in the service line.
B.The distributor tube inside the tank is not seated inside the valve or is damaged.
5. No further regeneration should be necessary at this time. If left at the default settings, the filter will automatically
initiate an air replenish cycle each night and will backwash every six days. If desired, these settings can be
changed in the main menu, or from the “advanced settings” screen in the Legacy View App.
Installation Requirements AIO Plus Connected Series

Final Check
1. Be certain that the bypass valve is in Service position and main valve is completely on.
2. Check electrical supply to be certain the cord is connected to an uninterrupted 120 volt outlet.
3. Leave this manual with the homeowner.
IMPORTANT NOTE: The plumbing system, piping, pressure tank, hot water tanks, softeners, etc. that have
been exposed to iron bearing water may need to be cleaned of the precipitated iron that has been collected in
them or iron bleed through may be a problem. We suggest all tanks be drained and flushed thoroughly.
Annual Maintenance
Annual replacement of the seal kit is required in all single tank air systems due to air drying of the seals over time.
Potential performance issues will result if this maintenance interval is not performed. Any system problems associ-
ated with this required system maintenance not being accomplished will not be covered by the factory warranty.

Normal Operation
1. Home Display
a. Alternates between the display of Time of Day and Number of Days until the Next Backwash. (Metered
Softeners will alternate between time of days and gallons remaining until next regeneration).
- Days Remaining until the Next Backwash will count down from the entered value until it reaches 1 day
remaining.
- A Backwash Cycle will then be initiated at the next designated regeneration time.
2. Battery Back-Up (Uses a standard 9-volt alkaline battery. Not included.)
Features of Battery Back-Up:
• During power failures, the battery will maintain the time of day as long as the battery has power. The display
is turned off to conserve battery power during this time. To confirm that the battery is working, press either
button and the display will turn on for five (5) seconds.
• If power failure occurs while system is regenerating, the system will motor to a shut off position to prevent
constant flow to drain. After power is restored, the system will return and finish the cycle where it left off prior
to the power interruption.
• When used without battery back-up during a power failure, the unit stops at its current point in the regeneration
position and then restarts at that point when the power is restored. The time will be offset by the increment
of time the unit was without power, so it is necessary to reset the time of day on the unit. No other system
settings will be affected.

Control Valve Error Code Diagnosis
Under normal operating conditions, when the control valve is in the “in service” position, the display should alternate
between the current time of day and the number of days remaining (for filters and time clock softeners) or gallons re-
maining (for metered softeners) until the next regeneration. This is the “home display.” If the valve is currently going
through a regeneration cycle, the display will show the cycle step on the left side of the display and the number of
minutes remaining in that step on the right side of the display. If any other information is being displayed, then the
valve is informing you of an issue. There are five error codes which could indicate an issue with the control valve.
When an error is being displayed, the valve will be in a stopped position, and the buttons will not respond to being
pressed. Even if the cause of the error code is corrected, the error code will not clear until the power supply has
been disconnected and reconnected (this will be referred to as “cycling” the power). All error codes are displayed as
the letters “Err” followed by a flashing number 2-6:
Error 2 - Valve is searching for homing slot. - Allow valve to continue running. If the homing slot is found, the valve
will return to the home display, otherwise, another error code will appear.
Error 3 - No encoder slots are being seen. - This occurs when the motor is running, but the encoder is not seeing any
of the slots in the encoder wheel. This can happen if the encoder has been disconnected, but most commonly occurs
when debris in the valve body has stopped the piston, causing the encoder wheel to be unable to turn.
1. Check encoder connection. If the encoder is plugged in and snapped into place, skip to step #2 below. If
encoder is disconnected, reconnect it and cycle power to clear the error.
2. Disconnect powerhead from valve body, cycle power to clear the error code. Manually cycle the powerhead
through the regeneration cycle steps to verify that the motor can cycle properly while the powerhead is
disconnected from the valve body. If the error 3 does not reappear, skip to step #3 below. If the error 3 does
reappear, order a board & motor kit to replace the circuit board & motor.
3. Remove piston and seals from the valve body and inspect valve body for debris. Replace the seal & spacer kit.
Inspect piston and replace piston if Teflon coating is worn
Error 4 - Unable to find homing slot.
1. Check encoder wheel for debris.
2. Cycle power. Valve should either find home or go to a different error code. If error 4 returns, replace powerhead
assembly.
Error 5 - Motor overload. - This occurs when the motor current is too high. This could be caused by an issue with the
motor itself, but is typically caused by friction in the valve body
1. Disconnect powerhead from valve body and cycle power to clear the error code.
2. If the error 5 returns, replace the motor. Otherwise, manually cycle the powerhead through the regeneration
