INTRODUCTION
General Information
• The system must be installed indoors and easily accessed for
service and maintenance.
• Use cold water only at a minimum of 50 psi and a maximum of
80 psi.
• A ½" water supply with full ow ball valve and pressure gauge,
drain, and 120VAC power supply is required within four (4) feet of
installation.
• Installation must conform to all local codes and regulations.
• Keep tubing and hoses as short as possible avoiding loops or
kinks in tubing. Do not cut tubing with wire crimpers or dikes.
• Install system as close as possible to the equipment served.
• Never restrict ow of water from the system to drain during
operation. This ow is necessary to carry contaminants away
from the membrane.
Installing or Replacing QT Cartridges
NOTE: Before installing or replacing QT cartridges, make
sure to remove the plugs in the QT heads.
1. Close feed water valve.
2. Twist and pull down to remove cartridges.
3. Align the upward-pointing arrow on the new cartridge
with the upward-pointing arrow on the head. Push
cartridge up into head until it stops.
4. Turn to right until it stops.
NOTE: labels might not always face forward.
5. Open feed water valve.

INSTALLATION
1. Mount the Processor
A. Select a secure mount location with access to water
supply, drain, and a 120VAC power supply.
B. Attach water processor at the upper and lower keyhole
mounts. DO NOT PLUG IN.
C. Using green tubing, connect the water supply to [A] water
processor feedwater inlet.

INSTALLATION CONTINUED
B. Route blue tubing to the optimized water storage tank.
C. Connect 3/8" blue tubing to the inlet of the tank inlet
divert valve.
4. Make the Storage Tank to Processor Connection
A. Connect ½" ID gray hose to ½ "hose barb adapter and
clamp. Then connect to [E] tank repressurization return.
E
½" hose barb adapter
and clamp (included).
B. Route gray hose to optimized water storage tank.
C. Connect ½" ID gray hose to the ½" hose barb adapter and
the clamp. Then connect to the repressurization assembly
outlet.
5. Make the Optimized Water Outlet
Connection
A. Connect ½" ID gray hose to ½"
hose barb adapter and clamp.
Then connect to [F] optimized
water outlet.
The optimized water line will
be connected directly to the
equipment, or to the optional
post-treatment lter, and then on
to the equipment.
DO NOT CONNECT THE LINE TO
THE EQUIPMENT AT THIS TIME.

6. Install Membrane and Pre-Filter Cartridges
A. Install the AMS-QT membrane into the QT head and turn to
align arrows. Remove plug from the elbow at the bottom of
the AMS-QT cartridge by pushing in on the gray collar and
pulling on plug.
B. Connect ¼" black reject tubing

C. Install two (2) CTO-Q cartridges into the QT heads 1 and 2
and starting from the left side of the processor and turn to
align arrows.
D. Install the MA-Q15 mineral cartridge in the same manner
into the forth (far right) head.
7. Make the Float Switch Connection
A. Connect tank switch cable connector.
Do NOT connect pump to power until the tank is at least
half full of water.

SYSTEM START-UP
1. Purge Air and Flush System
A. Turn emergency bypass valve to the “System Bypass” mode.
While holding the optimized water line over a drain, turn on
the water supply valve (user supplied). Allow to ush until
water runs clear and free of air.
B. Turn emergency bypass valve to the “Service” mode and
plug in the processor. Allow pre-lters and the membrane
to purge air and ush.
C. After several minutes the water will start owing to the
drain and the optimized water will start lling the tank.
(Optimized water ow rate is less than 0.25 gpm).
2. Check the Tank Float Switch and Set the Blend TDS
A. Check tank oat switch operation. Remove tank lid, raise
the oat (point upward) and listen for the solenoid valve to
click off and watch water ow to tank and drain stop. Lower
the oat to resume normal operation.
B. Set blending valve to desired optimized water TDS.
a. Turn on power to water quality indicator.
b. Press the "IN" button to determine optimized water TDS.
c. Adjust blending valve to user specied TDS.
Make ½ turn adjustments and wait 30 seconds until TDS
responds on meter.

3. Rapid Fill the Storage Tank
VERY IMPORTANT– PRIME THE REPRESSURIZATION (RP)
PUMP before connecting optimized water line to equipment.
To prime the RP pump the storage tank must be at least half
full.
A. While holding the optimized water line over the tank
opening, turn the emergency bypass valve to the “Bypass”
position.
B. DO NOT PLUG IN THE PUMP AT THIS TIME.
Allow the tank to reach half full.
C. When the tank is half full, turn the emergency bypass valve
to the “Service” position to resume normal operation.

4. Prime the RP Pump
A. Open the buffer tank valve
B. Holding the optimized water line over tank opening, plug in
RP pump and allow to run until water ow is steady and free
of air.
C. After ow is steady, close buffer tank valve and allow buffer
tank to ll. The RP pump should turn off. If the RP pump
does not turn off then air is present, repeat step 4b.
5. Make Connection to Equipment
A. Connect the optimized water line to post-treatment and
downstream equipment.
B. Open the buffer tank valve and start downstream
equipment. Check for leaks.
COMPLETE THE INSTALLATION
Secure tubing, hoses, and wires as needed to assure the
installation is neat and not susceptible to damage.
