Note: Valve must be in manual mode to adjust and save capacity and refill duration.

AIR DRAW INSTALLATION
Air check with screen (included)
Water check installed prior to unit (Included)
Aerus Origins® control valves are highly effective for Iron,
Hydrogen Sulfide and Manganese reduction by using our
unique “air draw” installation to introduce fresh air to the
filter tank for added oxidation.
Air draw is not required in many installations (depending on
Iron, Sulfur and Manganese concentrations), so testing is
advisable.
Factory settings for air draw installation:
•Valve is programmed for SOFTENER operation
•YELLOW injector is installed
•Regeneration is set using CALANDAR CLOCK
•Regeneration is set for 11:00 PM (may be adjusted)
•Capacity calculation is set as MANUAL
•Regen days set at “1” (to backwash every night)
•Backwash set at 30 MINUTES (may be adjusted)
•Brine rinse (air draw) set at 30 MINUTES
•Rapid rinse set at TWO MINUTES
•Refill set at ZERO
IMPORTANT: Well pump must be able to provide 7 gpm for
proper backwash. Evaluation required PRIOR to installation.
IMPORTANT: Disinfection (chemical treatment) is
required if water contains bacteria, iron bacteria or
sulfur bacteria. Site evaluation and testing is advised.

Connect Drain Line
Connect drain line to the valve
Slide drain line tube over barbed drain line
connection fitting until secured.
IMPORTANT
Proper backwash is critical for Iron/Sulfur filters Therefore, do not tee-off
drain line or use ½” drain tubing longer than 20’. (Use ¾” or 1” drain line for
longer runs).
CAUTION: Inspect valve for “brine plug” or air
draw valve installed at the factory. (Plug
is required to prevent water leaking
when valve advances)
!

System Installation
OUT
Turn the by-pass valves to the “OFF” position
(red valves) pointing “across” the valve as
shown.
With the faucet still on, open the main water
supply valve.
IN
Off Position
CAUTION: Inspect all plumbing connections. Check for leaks and make repairs as needed.

System Start Up
1) Press and hold to enter Manual Regen
Mode (press for 3-5 seconds)
2) Press to enter edit mode (flashing)
3) Press or to select immediate (flashing)
4) Press to save
5) Press to show “Advancing to Backwash”
Note: Valve will reset backwash cycle to delay after manual regen. cycle has finished.
Notice:
For initial start-up, the Inlet and Outlet valves on the bypass
should be in the closed position.

Start-Up In Backwash
1) Screen will now display
“Backwash” and flash
“Remaining XX min”
2) You will need to run
Backwash cycle until
drain line runs clear
NOTE: When advancing to another cycle, valve will show “advancing to”. Once the
valve is “in” a subsequent cycle, you may press any button to advance to
another cycle. Valve cannot be advanced while in the “advancing to” position.

Fill the Mineral Tank
1) With bypass valves in the
“OFF” position turn on the
main water supply.
2) Open “Inlet” valve slowly ¼
turn clockwise to fill the media
tank.
3) Slowly continue to open inlet
all the way once water is
flowing from the drain line.
If the mineral tank was not filled, do so at this time following the directions below:
CAUTION: Allow time for glued connections to cure before proceeding.
!
CAUTION: Inspect all plumbing connections. Check for leaks and make repairs as needed.
!
NOTE: Watch to see if the backwash flow rate is proper –do not obstruct
drain line. This is particularly important for Iron and Sulfur filters.

Press to advance to the next cycle
REPEAT of the initial backwash cycle may be required should the backwash
discharge water does not run “clear” after unit has finished the first cycle.
NOTE: It’s common to run multiple backwash cycles with carbon and Iron
filters due to the amount of “fines” in the media.
System Installation
Leave the system in backwash for a minimum
of ten to fifteen minutes or until the water
runs clear. This will flush loose particles and
preservatives from the media.

Ready for Service
1) Slowly open outlet to supply
water to the house.
2) Open faucet in the house to
remove debris and air to flush
system.

Weather Cover
(For outdoor installations)
WARNING
If the water treatment system is to be installed
outside, exposed to the weather and/or UV
Rays, it is necessary to install a weather cover
over the valve. The weather cover will protect
the valve from the damaging effects of UV
Rays on the LCD Screen and is required to
submit a warranty claim.
