Installation Requirements
This section and the next provide the water, electrical
and space requirements for the OP175. Pay
special attention to the feed-water chemistry
requirements. Operating a system on water supplies
outside of these parameters may lead to premature
membrane failure. This product is for commercial
use only and must be installed and maintained in
accordance with manufacturer’s guidelines and local
regulatory plumbing and electrical codes.
Operating parameters
Typical Membrane TDS* rejection:
97+%
Feed Temperature: 40 - 100° F (4 - 38° C)
Feed pressure: 50 - 80 psi
(3.4 - 5.9 bar) at 1 gpm
Production** (at 77°F, 60 psi)
184 gals/day,
7.7 gals/hr, 0.13 gpm
Recovery: up to 33%.
IMPORTANT NOTE: The nominal production rate
is strictly dependent on feed water temperature
and pressure. Reduced temperature or pressure
will reduce production. For example: Operating
pressure of 30 psi will cut production by 50%. 48˚F
feedwater will cut production by 50%.
Location
The system should be installed indoors, in the
proximity of the equipment (within 25 feet) and
protected from the elements. Do not let the processor
or storage tank freeze or be exposed to rain or direct
sunlight.
Post-treatment
Treated water stored in a tank may absorb organic
compounds from the tank, which can affect water
taste and odor. If product water is for consumption, an
optional post-treatment lter, such as an OptiPure
FX or QT carbon lter, should be installed after the
tank. If used, it is best installed as close to the point of
use as possible. Other specialized post-treatment is
also available.
Feed water connection
An adequate ow and pressure of water to the unit is
essential for successful operation. Provide a dedicated
1/2” water line to the vicinity of the installation. Install
a full-ow ball valve and pressure gauge with 1/2”
female pipe thread (user supplied) for connection to
installation hardware provided with the system. A 1/2”
*TDS (total dissolved solids) create conductivity in water and are
expressed in ppm or mg/l (parts per million or milligram per liter).
**Nominal production @ 77°F (25°C) @ 500 ppm based on a 24
hr day. Actual production will vary based on variations in water
temperature, pressure, and TDS.
male pipe thread x 3/8” push-to-connect adapter is
included in the installation kit.
Drain
A drain should be located within 5 feet of the location
of the unit. Drain must allow a minimum ow of 2
gallons per minute. Compliance with most local
plumbing codes requires installation of an approved air
gap in the drain line. The drain connection should be
accessible for system set-up and service.
Electrical requirements
A power source should be located within 5 feet of the
location of the unit.
RP Pump 120V 60Hz 2 Amps
Feed-water chemistry
Feed TDS Up to 1200 ppm
Feed pH 6 - 10
Hardness 28 grains or less
Free chlorine <2 mg/l
Iron (Fe) 0.1 mg/l max.
Turbidity <0.05 NTU
Manganese 0.05 mg/l max.
Hydrogen sulde 0.0 mg/l
A water analysis must be conducted before installing
the system or the information requested above can
be obtained from your local water utility. If your water
analysis shows that any of these parameters are not
within range, additional pretreatment and/or higher
frequency of maintenance may be required. Contact
your OptiPure distributor for assistance. The presence
of silica or occulants such as alum or cationic
polymers in the feedwater may cause membrane
fouling and may require special chemical pretreatment
or periodic membrane cleaning. Please note that
membrane failure due to fouling is not covered by the
warranty.
Storage Tank
The tank must be located within 10 feet of the water
processor unit. The oor beneath the storage tank
should be smooth, clean and free of sharp objects that
could puncture the bottom of the tank. Note: The tank
is atmospheric, with a sub-micron, hydrophobic air
breather lter.
Optimized Water Lines to Equipment
Tubing, piping and associated ttings connecting
Optimized water lines to equipment shoud be food
grade material that meets NSF Std 51 or 61 with a
minimum pressure rating of 75 PSI. Optimized water
may react with most metal piping imparting a bad
taste. Plastic pipe or reinforced opaque beverage
tubing are acceptable choices for Optimized water
distribution. The larger inside diameter tubing or hose,
the better to minimize pressure drop.

Wall Mounting
The processor unit should always be mounted where
it is well-supported, either using anchors in a cement
wall, or using the support of studs in a wall-board
wall. Never mount it directly to sheet-rock alone.
Instead, mount it on a sheet of plywood which is
anchored to the wall studs, as shown above.
Four user-supplied bolts or screws with a head
diameter of approximately 1/2” (which will t into the
keyholes in the system bracket, but will not slip out
when tightened) should be used to hang the system.
This will allow the unit to be lifted off the bolts, if
necessary for maintenance, without removing all
the bolts from the wall. Hold the processor in place
(without the cartridges) to mark the locations for
the screws. BE SURE TO ALLOW 3” BELOW THE
CARTRIDGES TO ALLOW FOR REMOVAL. Screw
the four bolts or screws in place, leaving approximately
1/4” clearance between the bottom of each bolt head
and the wall. Position the system over the mounting
bolts, and let the bracket slip down into the keyholes.
Tighten all screws.
System Installation
Note: Do not install the cartridges in the processor
until completing this section. Do not plug in the
power cord from the RP pump until completing the
following section, “System Start-Up”.
Refer to “Typical Installation” diagram on page 5
and “How to Use Our Quick-Connect Fittings” on
page 16 when making the following connections.
A feed water ball valve and pressure gauge (user

6. OPTIMIZED WATER TO EQUIPMENT: Connect
a piece of 1/2” i.d. gray hose the the OPTIMIZED
WATER OUTLET on the processor with a 1/2”
hose barb insert and clamp (supplied). The other
end of this line will be connected to the distribution
line that will deliver Optimized Water to the
equipment at a later time. Prepare any necessary
plumbing to make the connection between the
1/2” hose and distribution line, but for now leave
the line loose and route the loose end of the
gray hose into a drain or bucket (make certain
the hose length will reach the storage tank - this
will be required for the Start-Up procedures).
The equipment connection will be completed in
“Connect to Equipment.”
Optional RP Assembly Location
The Repressurization Pump and Buffer Tank assembly
is on a stand that can be remote from the storage tank.
Simply remove the four bolts on the feet of the bracket
and lengthen the gray hose from the tank to the pump
and the red bypass tubing from the Tank Inlet Divert
Valve to the required length. Four rubber feet and
mounting screws are available to put on the bottom of
the Tank Stand. Kit Part number 164-89116.

5).
from the Optimized Water Outlet on the Processor
to the distribution line feeding the equipment that
will be using the Optimized Water.
IMPORTANT: Before proceeding, position the
Processor EMERGENCY BYPASS VALVE in the
“SERVICE” position, assure that the Buffer Tank Valve
is closed, and position the TANK INLET DIVERT
VALVE to bypass the tank (Blue Valve Handle pointing
up).
1. Slowly open the user-supplied WATER SUPPLY
VALVE and allow the lter housings to ll. Water
will begin to ow from the end of the 1/4” black
tubing routed to the drain. After some time, water
will begin to ow from the gray hose which is
temporarily routed to a bucket or the drain. Allow
several minutes to ush the system until water
ows smoothly from the gray hose and drain line.
Check all of the plumbing connections and correct
any leaks if necessary.
2. The tank must be ll to start-up and purge the
Repressurization Assembly. You can quickly ll the
storage tank using the “System Bypass” on the
processor. To do this use the following:
• Route the 1/2” gray hose from the OPTIMIZED WATER
OUTLET directly into the storage tank.
• Turn the EMERGENCY BYPASS VALVE on the processor
to “BYPASS.” This will allow feed water to bypass the
processor and quickly ll the storage tank.
• When the tank lls to approximately 14 gallons return
the processor EMERGENCY BYPASS VALVE to the
“SERVICE” position. When the tank is full, the shutoff
valve will close, stopping all ow.
• With the tank full, ensure the valve at the top of the BUFFER
TANK is in the OPEN position and that the 1/2” gray hose is
still directed into the storage tank.
3. Plug the power cord from the RP pump into the
outlet. Water should begin to ow rapidly from the
storage tank, through the RP assembly and back
into the storage tank through the gray hose. Allow
the pump to run for several minutes until all of the
air is purged from the Repressurization Assembly.
As the air is purged, the pump will run more
smoothly and the water ow from the gray hose
will become steady.
4. Unplug the RP Pump cord.
Connect to Equipment
You are almost ready to enjoy the benets of
Optimized Water. All that remains is to make the
connection for distribution to your equipment.
3. Ensure that any valves or solenoid valves on the
connected equipment are closed. Plug the RP
pump back in. The pump will run and will ll the
Buffer Tank until the pressure in the Buffer TAnk
reaches 70 psi, and then the RP Pump will shut
off.
4. Open downstream valves at the equipment to
allow air to purge from the distribution lines. When
purging distribution lines do not allow the water
level in the storage tank to drop below 1/4 full.
Once purged and ushed, close the equipment
valves. When there is no demand for water the
pump will shut off automatically.
5. Turn the TANK INLET DIVERT VALVE to the
“TANK” position (blue valve handle pointing down).
Complete the Installation
Transition to Owner/Operator
The nal step is to meet with the owner/operator,
familarize them with the system and complete the post
installation check list.
The system is now in “normal operating” mode and
the storage tank will ll with Optimized Water from
the processor. Complete the “Check List” to “Conrm
Normal Operation and System Settings” (page 4 of the
“Quick Installation Guide”) with the Owner/Operator.
Allow the tank to ll before beginning operation of the
connected equipment.
Reading the TDS
1. Push the purple “POWER” button on the Water
Quality Monitor located on the upper left corner.
It will immediately display the “IN” or Optimized
Water TDS (Total Dissolved Solids) in PPM
(parts per million). Document this number as the
Optimized Water TDS.
2. Within 30 seconds, push the “OUT” button to
display the Membrane Permeate TDS and record
this number as the Permeate TDS.
1. Remove the 1/2” gray hose from the storage tank
and replace and tighten the lid to the storage tank.
2. Complete the connection of the 1/2” gray hose

This section will give you an overview of how
the system works.
• Incoming water is ltered by the prelters
(1), which remove sediment, chlorine and
organics.
• When the Emergency Bypass Valve (3) is
in the normal SERVICE mode, water ows
through the Processor. When the Bypass
Valve (3) is in System Bypass mode, the
water is diverted directly out to the equipment,
bypassing both the Processor and the
Repressurization Assembly.
• When water in the storage tank is at a low
storage level, the oat valve at the tank
(12) opens, lowering the pressure in the
Optimized Water line from the Processor to
the Repressurization Assembly, causing the
Automatic Shutoff Valve (4) in the Processor
to open, allowing feed water to ow through to
the AMS-QT15 membrane (7).
• The membrane feed water pressure is
indicated by the pressure gauge (6).
• The water ows to the inlet of the membrane
(7). The water is split by the membrane into a
pure water stream and a reject water stream.
The reject water ows to the Reject Flow
Control (10) and then on to drain.

• The pure water stream continues through the
Permeate Check Valve (8), and through the
Mineral Addition cartridge (2), then on to the
tank through the Tank Inlet Divert Valve (11)
on top of the Storage Tank (14). Air in the
tank is displaced by the incoming water and
vented out of the Sub-Micron Air Breather
(16).
• When the tank completely lls, the tank
oat valve (12) closes, causing pressure
in the Optimized Water Line to rise, which
then causes the Automatic Shutoff Valve
(4) to close, stopping the ow through the
Processor.
• When the “IN” button is actuated on the
Water Quality Monitor (9), it measures the
average TDS of the Optimized Water in
the Pressurized Water Line coming from
the storage tank. When the “OUT” button
is actuated, the Water Quality Monitor (9)
indicates the TDS of the Permeate water
exiting the Membrane (7). If the Bypass Valve
(3) is in System Bypass mode, the Water
Quality Monitor (9) will measure the TDS of
the untreated Feed Water when the “OUT”
button is actuated. The Water Quality Monitor
(9) is battery powered with two AA batteries. It
will automatically shut-off after 30 seconds.
OP175 System Installation, Operation & Maintenance 11
• The Repressurization Pump (15) is designed
to draw water from the Atmospheric Storage
Tank (14) and dispense the Optimized water
to the Processor and through the One-Way
Check Valve (5) and out to the equipment.
A Buffer Tank (18) between the pump and
the downstream equipment to prevent short
cycling of the pump for low volume demands.
The Repressurization Pump is equipped with
a pressure switch so that when the pressure
in the Buffer Tank drops, the Pump runs to
repressurize the Buffer Tank, and when the
pressure reaches 70 psi, the Pump shuts off.
• Water demand for downstream equipment is
directly supplied from the Buffer Tank (18),
and demand can go on and off as necessary.
The RP Pump is not directly affected by
downstream demand, but only activates in
response to a sufcient drop in Buffer Tank
pressure. Downstream equipment is also not
affected by the automatic starting or stopping
of the RP Pump.
• The Optional Post-Treatment Filter (20) is
designed to provide additional treatment
based upon specic application requirements.
For beverage applications an activated
carbon lter is recommended.
• As Optimized Water is dispensed from the
storage tank by the Repressurization Pump
(15), air is replaced in the tank through the
Sub-Micron (0.2 micron) Air Breather (16).
• If the Repressurization Pump (15) fails, water
ow and can be restored to the equipment by
turning the Emergency Bypass Valve (3) to
the position to “SYSTEM BYPASS” position.
This allows tap water to bypass the processor
and RP assembly.
Repressurization Pump
The Repressurization Pump Assembly that comes
standard with the OP175 System includes a
diaphragm pump controlled by a built-in Pressure
Switch, and a Buffer Tank between the Pump and
the downstream equipment maintains pressure
downstream. When a valve or solenoid valve is
opened down-stream of the Buffer Tank, the demand is supplied from the Buffer Tank. When the
pressure drops sufciently in the Buffer Tank, the
pump starts automatically and rells the Buffer
Tank. The operating pressure for the Buffer Tank
is preset (to 70 psi) and is NOT eld adjustable.
The pump also incorporates check valves to keep
the Buffer Tank and downstream line pressurized.
The pump is equipped with auto-reset, thermal
overload protection and is designed for intermittent duty.
If the pump runs erratically, allow the pump
to run to open drain with valve fully open to
purge air from the pump head. Disconnect the
power and reconnect several times to facilitate air purging.
Pump will prime only if all the pressure is relieved
from the outlet port. The pump is self-priming up
to 11 ft. The pump can run dry but will overheat
and the pump overload will shut the pump off.
• A Sample Port (13) provides the ability to
measure membrane production by closing
the Buffer Tank Valve (17) and turning the
Tank Inlet Divert Valve (11) to the bypass
or UP position. This diverts the permeate
(pure water produced by membrane) from the
Storage Tank (14) through the Bypass Check
Valve (19) and back to the processor where
opening the Sample Port (13) will allow you to
directly measure the permeate ow rate.
• Additionally the Sample Port (13) provides
the ability to drain water from the Storage
Tank (14) by closing the user-supplied Water
Supply Valve, opening the Buffer Tank Valve
(17) and opening the Sample Port (13).

Routine Maintenance: Filter Change Procedure
The only routine maintenance required on the
system is periodic replacement of the carbon/
sediment pre-lters and the mineral addition
cartridge. The CTO-Q10 cartridges should be
changed every 3-6 months depending on water
usage. In areas with high levels of sediment and
other contaminants the CTO-Q10 cartridges may
require more frequent changes. The mineral
addition cartridge should be changed when the
Optimized Water TDS drops.
Pre-Filter change procedure
1. Either close the Water Supply Valve (shutting
off all water ow), or put the Emergency
Bypass Valve (on the Processor) in the
System Bypass position (allowing untreated
water to continue to ow to the equipment).
2. Wait a moment for system pressure to drain
off.
3. Once the system pressure has been relieved,
remove the two CTO-Q10 cartridges by
turning a quarter-turn to the left and pulling
down on the cartridge.
9. Check for leaks.
Optional Post-treatment cartridge change
procedure
(if applicable)
1. Close the ball valve at the inlet to the PostTreatment assembly.
2. Remove the existing cartridge and discard.
3. Install the new cartridge.
4. Open the ball valve and the RP pump should
actuate lling the housing with water.
4. Install the new CTO-Q10 cartridges into
the QT heads by aligning the notches and
pushing up, then turn a quarter-turn to the
right.
5. If it is necessary to replace the Mineral
Addition Cartridge, repeat steps 4 - 5 for the
Mineral Addition Cartridge.
6. Install a piece of 3/8” tubing in the Processor
Sample Port valve, open the Sample Port,
and direct to a bucket or drain.
7. Turn the Tank Inlet Divert Valve to the Bypass
Mode (Handle Pointing UP).
8. Open the Water Supply Valve and put the
Emergency Bypass Valve in the “SERVICE”
position, allowing water to run into the new
Pre-Filter cartridges and purge air through
the system and out the Sample/Flush Port to
drain.
9. Once the air has been purged and lters
ushed, close the Sample Port valve and
return the Tank Inlet Divert Valve to the
Normal position (handle horizontal or down).

Routine Maintenance: AMS-QT15Change Procedure
The AMS-QT15 membrane is a high-efciency, low-
fouling reverse osmosis membrane that will provide
product water with 95+% rejection of the Feed Water.
The life of the membrane will vary depending on Feed
Water quality, usage, and Pre-Filter maintenance.
Typical membrane life is 12 to 18 months, but with routine scheduled Pre-Filter replacement, and no adverse
Feed Water conditions, the AMS-QT15 membrane
may last 2-5 years.
AMS-QT15 Replacement
1. Either close the Water Supply Valve (shutting off
all water ow), or put the Emergency Bypass Valve
(on the Processor) in the System Bypass position
(allowing untreated water to continue to ow to the
equipment).
2. Place a bucket or other similar catch basin under
the AMS-QT15. Remove the black reject line from
the push-to-connect elbow on the bottom of the
membrane. (Refer to “Push-to-Connect Fittings”
on page 16.) Allow the membrane and reject line
to drain into the bucket.
3. Remove the AMS-QT15 cartridge from the head
by turning the cartridge a quarter-turn to the left
and pulling down on the cartridge.
4. With a wrench, remove the push-to-connect elbow
and stem adapter attached to the bottom of the
AMS-QT15 cartridge. Remove the residual Teon
tape from the male 1/8” threads on the stem
adapter.
5. Wrap the 1/8” male thread on the stem adapter
with 2 wraps of Teon tape and re-install in the
bottom of the new AMS-QT15 cartridge.
6. Align the taps on the AMS-QT15 cartridge with
the QT head and insert into the head and turn a
quarter-turn to the right.
7. Insert the black reject line into the push-to-connect
elbow on the bottom of the AMS-QT15 cartridge.
8. Install a piece of 3/8” tubing in the Processor
Sample Port valve, open the Sample Port, and
direct to a bucket or drain. Turn the Tank Inlet
Divert Valve to the Bypass or UP position. Open
the Water Supply Valve and put the Emergency
Bypass Valve in the “SERVICE” position. Allow
water to ush through the membrane displacing air
and preservative to ow out the Sample/Flush port
to drain for 5-10 minutes.
9. Actuate the Water Quality Monitor and check the
“OUT” or Permeate Water TDS.
10. After the AMS-QT15 cartridge is purged of air,
close the Sample Port.
11. Check for leaks.
