Installation
Unpack Carbon Filter. Inspect assemblies for damage (cracked couplings, broken or split pipes, loose straps, etc.).
Location
Select a location for the Carbon Filter with adequate clearance from walls and other equipment to allow access on all
sides of the tank. The unit must be located near a drain able to accommodate the backwash flow rate of your unit (see
the table on page 3). This is in addition to any other equipment sharing the drain.
A grounded power supply of the appropriate voltage and a local disconnect switch is required.
Caution: The unit must not be located near any corrosive chemicals, or in an area where the
temperature may exceed 113°F (45°C).
Warning: The power supply must be properly grounded to avoid injury from electrical shock.
If media shipped unloaded (packaged separately outside of the tank) then continue with the loading instructions. If the
carbon filter was shipped loaded, please skip to plumbing.
LoadingtheMedia
1. Place tank on a level, solid surface in the correct position for installation. Lift the riser tube
from the tank, keeping the attached hub within the opening of the tank. Within the tank,
assemble the laterals onto the hub, twisting each lateral into the hub to lock securely.
Gently lower the assembly to the bottom of the tank. The top of the riser tube should be
about level with the top of the tank.
2. The “riser tube” inside the media/resin tank delivers treated water to your control valve. It
will need to be temporarily covered with tape on the top end to prevent anything from falling
down inside the tube during loading.
3. Step back and look at the tank to make sure it is standing straight, and not tilted. The black
base on the bottom of the tank should also be straightened before filling the tank. If your
tank is tilted, simply pick up the tank 2-3 inches off the floor and drop it gently (but firmly)
down, favoring the side of the base that needs to be adjusted.
4. Before loading the media, fill the tank with 2-3 feet of water (or 1/3 full, depending on the
tank size), to soften the fall of the rocks and prevent damage to the distributor. To load the
media, use a funnel in the top of the media tank with the riser tube still inside. Make sure
the riser tube is covered with tape to keep media out.
5. Scoop the media into the funnel, slowly letting it fall down inside the media tank around the riser tube. Fill the tank with
the media provided, pouring the media in the following order (1st will end up on the bottom of the tank, last will end up
at the top of the tank, etc.). Note: The tank will be approximately ½ - ⅔full after loading is complete. Refer to table on
the following page for the proper quantities of each media.
I. Gravel – YMGRVL11618 – 1 CF (100 lbs.) per bag
II. Carbon – YMC1240RCOAL – 1 CF (27.5 lbs.) per bag
6. Remove the funnel from the top of the tank, and the tape from the end of the riser tube. Brush any loose media off the
top opening of the tank.
7. The bottom of the control valve has an opening with O-rings inside; lubricate the O-ring with a non-petroleum based
lubricant. Position the valve over the top of the media tank, making sure the top of the riser tube inserts inside the
opening in the bottom of the valve.
8. Screw the valve down into the media tank. Another person should hold the tank as the valve is being snugly tightened
onto the tank. Do not over-tighten. Tighten until snug, tighten a bit more, and then STOP. The large o-ring will seal
itself.

Plumbing
1. Install connecting piping between raw water source and input pipe on control valve.
The installation fittings connect to the control valve or the bypass valve using nuts that only require hand
tightening. Do not use a pipe wrench to tighten nuts on installation fittings. The split ring design, incorporated into
the installation fittings allows approximately 2 degrees off axis alignment to the plumbing system. The installation
fittings are designed to accommodate minor plumbing misalignments but are not designed to support the weight
of a system or the plumbing.
When assembling the installation fitting package, connect the fitting to the plumbing system first and then attach
the nut, split ring and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring.
Solder joints should be cool and solvent cements should be set before installing the nut, split ring and o-ring.
Avoid getting primer and solvent cement on any part of the orings, split rings, bypass valve or control valve.
Solvent cements and primers should be used in accordance with the manufacturer’s instructions.
Slip the nut onto the fitting first, then the split ring second and the o-ring last. Hand tighten the nut. If the fitting is
leaking tightening the nut will not stop the leak. Remove the nut, remove the fitting, and check for damage or
misalignment of the o-ring.
Do not use pipe dope or other sealant on threads. Use teflon tape on threaded inlet, outlet and drain fittings.
Teflon tape is not necessary on the nut connection or caps because of o-ring seals.
Note: All plumbing is to be done in accordance with state and local codes.
Caution: Before placing wall anchors to support piping ensure that no electrical conduit or wiring is located
behind the intended mounting location.
Note: The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments
but are not designed to support the weight of a system or the plumbing.
2. Install drain line from control valve to a free flowing drain.
If the drain line is a ⅝” flexible polytube, slide the nut onto the polytube, then place the polytube insert into the end
of the polytube and tighten the nut on to the ¾” drain line fitting. The nut is only designed for use with fexible
polytube. Use other nuts if attaching different materials. (To access the drain line flow control, remove the locking
clip by pulling it straight out. Pull fitting out and replace the locking clip so that it is not misplaced. The drain line
fitting is pressed in and has an o-ring seal.)

3. Install piping between carbon filter output and point of use.
The installation fittings connect to the control valve or the bypass valve using nuts that only require hand
tightening. Do not use a pipe wrench to tighten nuts on installation fittings. The split ring design, incorporated into
the installation fittings allows approximately 2 degrees off axis alignment to the plumbing system. The installation
fittings are designed to accommodate minor plumbing misalignments but are not designed to support the weight
of a system or the plumbing.
When assembling the installation fitting package, connect the fitting to the plumbing system fi rst and then attach
the nut, split ring and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring.
Solder joints should be cool and solvent cements should be set before installing the nut, split ring and o-ring.
Avoid getting primer and solvent cement on any part of the orings, split rings, bypass valve or control valve.
Solvent cements and primers should be used in accordance with the manufacturer’s instructions.
Slip the nut onto the fitting first, then the split ring second and the o-ring last. Hand tighten the nut. If the fitting is
leaking tightening the nut will not stop the leak. Remove the nut, remove the fitting, and check for damage or
misalignment of the o-ring.
Do not use pipe dope or other sealant on threads. Use teflon tape on threaded inlet, outlet and drain fittings.
Teflon tape is not necessary on the nut connection or caps because of o-ring seals.

General Warnings
The control valve, fittings and/or bypass are designed to
accommodate minor plumbing misalignments but are not
designed to support the weight of a system or the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants
or spray silicone anywhere. A silicone lubricant may be
used on black o-rings but is not necessary
The nuts and caps are designed to be unscrewed or
tightened by hand or with the special plastic wrench. If
necessary pliers can be used to unscrew the nut or cap. Do
not use a pipe wrench to tighten or loosen nuts or caps. Do
not place a screwdriver in the slots on caps and/or tap with
a hammer.
The nuts and caps are designed to be unscrewed or
tightened by hand or with the special plastic wrench. If
necessary a pliers can be used to unscrew the nut or cap.
Do not use a pipe wrench to tighten or loosen nuts or caps.
Do not place a screwdriver in the slots on caps and/or tap
with a hammer.
After completing any valve maintenance involving the
drive assembly or the drive cap assembly and pistons
unplug power source jack from the printed circuit board
(black wire) and plug back in or press and hold SET and
DOWN buttons for 3 seconds. The cover button may have
other names like “SET HOUR”, “CLOCK” or “SET CLOCK”
but the circuit board is labeled with SET.
This resets the electronics and establishes the service
piston position. The display should flash all wording, then
flash the software version and then reset the valve to the
service position.
Do not use pipe dope or other sealants on threads. Use
Teflon tape on the threaded inlet, outlet and drain fittings.
Teflon tape is not necessary on the nut connection or caps
because of o-ring seals.
All plumbing should be done in accordance with local
plumbing codes. The pipe size for the drain line should be a
minimum of ½”. Backwash flow rates in excess of 7 gpm
(26.5 lpm) or length in excess of 20’ (6.1m) require ¾” drain
line.
Solder joints near the drain must be done prior to
connecting the drain line flow control fitting. Leave at least
6” between the drain line control fitting and solder joints
when soldering pipes that are connected on the drain line
control fitting. Failure to do this could cause interior damage
to the drain line flow control fitting.
When assembling the installation fitting package (inlet
and outlet), connect the fitting to the plumbing system first
and then attach the nut, split ring and o-ring. Heat from
soldering or solvent cements may damage the nut, split ring
or o-ring. Solder joints should be cool and solvent cements
should be set before installing the nut, split ring and o-ring.
Avoid getting primer and solvent cement on any part of the
o-rings, split rings, bypass valve or control valve.
Plug into an electrical outlet. Note: All electrical
connections must be connected according to local codes.
(Be certain the outlet is uninterrupted.) Install grounding
strap on metal pipes.
Control Valve General Features and Information
This fully automatic control valve is designed as the primary control center to direct and regulate all cycles of an automatic
backwashing filter. The control valve included with this system is equipped with a meter and can be set to regenerate on
demand (consumption of a predetermined amount of water) and/or as a time clock* (passage of a particular number of
days).
The control valve regulates the flow rates for backwash and rinse cycles.
The control valve uses no traditional fasteners (e.g. screws); instead clips, threaded caps and nuts and snap type latches
are used. Caps and nuts only need to be firmly hand tightened because radial seals are used. Tools required to service
the valve include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench
is available which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than
com parable products currently on the market. Control valve installation is made easy because the distributor tube can be
cut ½” above to ½” below the top of tank thread. The distributor tube is held in place by an o-ring seal and the control
valve also has a bayonet lock feature for upper distributor baskets.
The AC adapter comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter is for dry
location use only. The control valve maintains timekeeping for up to 8 hours if the power goes out and the battery is not
depleted. After 8 hours, the only item that needs to be reset is the time of day; valve status and programming are
permanently stored in the nonvolatile memory. If a power loss lasts less than 8 hours and the time flashes on and off, the
time of day should be reset and the non-rechargeable battery should be replaced.

• Installer Displays & Settings
• User Displays
• Diagnostics
• Valve History
These procedures can be accessed in any order. Details on each of the procedures are provided below and on the
following pages.
At the discretion of the installer, the end user can access all settings. To “lock out” access to diagnostic and valve history
displays and modifications to settings except hardness, day override, time of regeneration and time of day by anyone but
the installer, press ▼, NEXT, ▲, and SET CLOCK in sequence after settings are made. To “unlock”, so other displays
can be viewed and changes can be made, press ▼, NEXT, ▲, and SET CLOCK in sequence.
When in operation, normal user displays show the time of day or days remaining before regeneration. When stepping
through a procedure, if no buttons are pressed within five minutes the display returns to a normal user display. Any
changes made prior to the five minute time out are incorporated. The one exception is current flow rate display under the
diagnostic procedure. The current flow rate display has a 30 minute time out feature.
To quickly exit Filter Setup, Display Settings, Diagnostics or Valve History press SET CLOCK. Any changes made prior to
the exit are incorporated.
When desired all information in Diagnostics may be reset to zero when the valve is moved to a new location. To reset to
zero, press NEXT and ▼buttons simultaneously to go to the Service/Setup 1 screen, and release. Press ▲and ▼
simultaneously to reset diagnostic values to zero. Screen will return to User Display.
Regeneration Cycle Programs
Table 3 shows the possible orders of the cycles for a downflow water filter. When the control valve is used on a carbon
filter, the program provides to option to specify one backwash or two backwashes. If two backwashes are specified, two
rinses occur. Table 3 – Regeneration Cycle Order
for Downflow Water Filters

*Second backwash is optional. Second rinse only occurs if second backwash option is selected.
Backwashes can be set to NORMAL or to LONGER. The option selected will apply to both backwashes. Table 1 shows
the length of the cycles.
AMI Carbon Filters are programmed for NORMAL Length SINGLE Backwash as default. This should work for most
applications. If LONGER or DOUBLE Backwash options are required, please see OEM programming section for setup
instructions.

Demand Initiated Regeneration & Time Clock Options
The control valve can be set for Demand Initiated Regeneration (DIR) only, Time Clock operation only or DIR and Time
Clock whichever comes first, depending upon what settings are selected for Day Override and Gallon Capacity.1 See
Table 3.
1See the Installer Display Settings, Step 3I, Filter System Setup Step 6S for explanations of Day Override and Gallon Capacity.
AMI Metered Carbon Filters are programmed for manual gallons capacity with a 12-Day Override as default. This
should work for most applications. If different regeneration settings are required, please see OEM programming section
for setup instructions.
Table 5 – DIR (Demand Initiated Regeneration) & Time Clock Options
DIR Time Clock Settings
4
Days Override Gallon Capacity
Yes OFF Any Number
Default Yes Yes Any Number
(Default = 12) Any Number
Yes Any Number OFF
For DIR Filters, set the Gallons Capacity to a specific number. Automatic reserve capacity feature is available for water
softeners only. If a reserve capacity is desired, set the gallon capacity to a value that is lower than the estimated capacity.
The control valve can also be set to regenerate immediately or at the next regeneration time by changing the
Regeneration Time Option. There are three choices for settings:
1. “NORMAL” (sometimes referred to as “meter delayed”) means when the gallons capacity reaches zero, it will stay
in service until the next preset regeneration time, at which time regeneration will begin.
2. “on 0” means regeneration will occur immediately when the gallons capacity reaches zero.
3. “NORMAL” and “on 0” means the regeneration will occur at the preset regeneration time unless the gallons
capacity reaches zero. If the gallons capacity reaches zero the regeneration will begin 10 minutes after no water
usage.
AMI Carbon Filters are programmed to NORMAL (meter delay) regeneration option. This should work for most
applications. If different regeneration settings are required, please see OEM programming section for setup instructions.

Manual Regeneration (Backwash)
Manual regeneration can be performed at any time.
To schedule a regeneration to occur at the next delayed
regeneration time of day: Press and release the REGEN button.
“Regen Today” will flash on the display and the regeneration will occur at
the preset delayed regeneration time. The regeneration can be cancelled
by pressing and releasing the REGEN button. This method of manually
initiating regeneration is not allowed when the system is set to “on 0”
(meter immediate), because there is no preset meter delay time.
“REGEN TODAY” will flash if a
regeneration is expected “Tonight”.
To begin an immediate regeneration: Press and hold the REGEN button for approximately 3 seconds. The
regeneration will begin immediately. This cannot be cancelled, except by resetting the control by pressing NEXT
and REGEN buttons simultaneously for 3 seconds.
The control valve may be stepped through the various regeneration cycles by pressing the “REGEN” button.
Sometimes it is desirable to have the valve initiate and complete two regenerations within 24 hours and then return to the
preset regeneration procedure. It is possible to do a double regeneration if the control valve is set to “NORMAL” or
“NORMAL + on 0”. To enact a double regeneration:
1. Press the “REGEN” button once. REGEN TODAY will flash on the display.
2. Press and hold the “REGEN” button for three seconds until the valve regeneration initiates.
Once the valve has completed the immediate regeneration, the valve will regenerate one more time at the preset
regeneration time.
Additional Control Valve Functions
Water Usage Monitoring
The metered control valve will display actual water usage for the last 63 days. The values are initially stored as
“----”. This means the value is unknown. As days pass values are stored as “0” for no flow or the actual number of gallons.
The counting of the gallons starts at the regeneration time. If no regeneration time can be set (i.e. when the valve is set for
immediate regeneration) the counting of gallons starts at 12 a.m. Day 1 is yesterday, day 2 the day before yesterday, etc.
As new values are added the oldest history disappears.
Power Loss
Only the current time of day will need to be reset if power is lost for greater than 8 hours. If power is lost while the system
is regenerating, the control will complete regeneration at the point of interruption once power is restored.

Installer Display Settings
STEP 1I
Press NEXT and ▲simultaneously for 3 seconds to enter Installer Settings Screen.
STEP 2I
This display should show “–nA–”
Press NEXT to go to step 3I. Press REGEN to exit Installer Display Settings.
(If Hardness Grains appear as shown on the left, the valve is incorrectly set up as a
Softener: return to step 2F and refer to Filter System Setup instructions to correct.)
STEP 3I
Day Override: When gallon capacity is set to AUTO or to a number, Day Override
sets the maximum number of days between regenerations. Recommended Setting
for Days Override = 12 Days. If value set to “OFF” regeneration initiation is based
solely on gallons used. If value is set as a number (allowable range from 1 to 28) a
regeneration initiation will be called for on that day even if sufficient number of gallons
were not used to call for a regeneration. Set Day Override using ▼or ▲buttons:
number of days between regeneration (1 to 28); or
“OFF”.
When gallon capacity is set to off, the valve operates as a time clock valve and the
Day Override sets the number of days between regenerations.
See Setting Options Table for more detail on setup.
Press NEXT to go to step 4I. Press REGEN to return to previous step.
STEP 4I
Next Regeneration Time* (hour): Set the hour of day for regeneration using ▼or ▲
