BWS175 Simple Install Guide 3
vInstallation Requirements
Operating a system on water supplies outside
of the parameters listed below 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 codes.
Operating Parameters
Typical Membrane TDS Rejection: 97+% Feed
Temperature: 40˚ - 100˚F (4˚ - 38˚C) Feed
Pressure: 50 - 80 psi (3.4 - 5.5 bar) at 1 gpm
Production (at 77˚F, 60 psi to atmosphere):
175 gpd (7.3 gph)
Recovery: Up to 33%
IMPORTANT NOTE: The production rate is
strictly dependent on feedwater temperature
and pressure.
For example: Operating pressure of 30
psi will reduce production by 50%, or
48˚F feedwater will reduce production by 50%.
Location
The system should be installed indoors, within
25 feet of the equipment water is being
supplied to, and protected from the elements.
Do not let the processor or storage tank freeze
or be exposed to rain or direct sunlight.
Feed Water Connection
An adequate flow and pressure of water to the
unit is essential for successful operation.
Drain
A drain should be located within 10 feet of
the system. Drain must allow a minimum ow
of 2 gals./min. 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.
Feedwater Chemistry
Feed TDS: Up to 1200 ppm
Feed pH: 6 - 10
Hardness: 12 grains or less
Free Chlorine: <2 mg/L
Iron (Fe): 0.1 mg/L maximum
Turbidity: <0.05 NTU
Manganese: 0.05 mg/L maximum
Hydrogen Sulde: 0.0 mg/L
Note: The presence of silica or occulants
such as alum or cationic polymers in the
feedwater may cause membrane fouling and
may require special pretreatment. 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. The oor beneath the
storage tank should be smooth, clean and
free of sharp objects that could puncture the
bottom of the tank.
Optimized Water Lines to Equipment
Tubing, piping and associated ttings used to
connect optimized water to equipment should be
food grade material with a minimum pressure rating
of 75 PSI. Non-metal, plastic pipe or reinforced hose
or tubing are recommended. For distribution runs
longer then 15 feet use larger inside diameter tubing
or hose to minimize pressure drop.

possible to maximize water pressure
and ow. Cut tubing to an efficient
length using a proper tube cutter for
a clean, square cut. When routing
and securing tubing avoid loops or
kinks.

Mount the system with the Pre-Installed Drain Line
(1/4” black), Bypass Assembly (3/8” red), and Blend
Valve Assembly (1/4" blue) as shown below.
Step 1
Attach the system with 2 screws (user supplied) through the attachment keyholes shown
below. Use anchors or attach directly to studs. Be sure to allow at least 3” clearance
below cartridges for removal.
vMount Processor
Use Keyholes in Bracket

Step 2a
Insert the AMS-QT15 Membrane into the center
head and rotate it to the right 1/4 turn to lock.
Step 2b
Remove the plug from the tting at the bottom
of the Membrane and insert the end of the
black tubing coming from the lower left part of
the Permeate Pump.
Attention: Warranty will be void if
this step is not performed properly.
Step 3
Insert and lock the CTO-Q10 Cartridge into the
Pre-Filter Head as shown.
NOTE: The pre-lter head has a built-in shut o
valve. When the lter is removed, water will not
ow. When the lter is installed, water will ow
to the system.

Step 4
Route and connect the loose end of 1/4” black
(DRAIN) tubing coming from Permeate Pump on
processor to a suitable drain; cut to length and
fasten to the wall and at the drain connection.
(Some locations may require an approved air
gap. Optional OptiPure Air Gap available, part
number: 164-89905)
Step 5a
Install the Feedwater Adapter (from the
installation kit) into the user-supplied 1/2”
Feedwater Supply Valve. (Do not over-tighten.)
Step 5b
Connect a piece of 3/8” green tubing to the
Feedwater Supply Valve. Connect the other end
to the Feedwater Inlet on processor.
Step 6
Install the Tank Valve – hand tighten. Cut a piece
of 3/8” tubing 1 1/2” to 2” long and install the
3/8” Tee as shown above. Ensure the Valve is
CLOSED.

Step 12
Turn the Tank Valve to the OPEN position. The
installation is complete and the system is ready
to be placed into service.
Step 11
Set blending valve to desired optimized
water TDS:
•Close the Storage Tank valve and
run optimized water line to drain
temporarily.
•Push the "on/off" button on the
water quality monitor. It will display
the optimized water's TDS (total
dissolved solids) in PPM (parts per
million).
•To increase Optimized water TDS
turn the blending valve knob
counter-clockwise, this will increase
the amount of filtered water
blending with the re-mineralized RO
water.
•To decrease Optimized water TDS
turn the blending valve knob
clockwise, this will decrease the
amount of filtered water blending
with re-mineralized RO.
•Once the desired TDS is obtained
allow the system to run for several
minutes periodically checking the
TDS. Make smaller incremental
adjustments as necessary until the
TDS " target" is achieved.

BWS175 Simple Install Guide 12
If a water supply to downstream
equipment is immediately
needed, the storage tank can be
quickly lled.
v Place in Service
Step 13
OPEN the Feed Suppy Valve and check for
leaks. Allow time for the tank to ll before
using connected equipment (this could take 30
minutes to several hours depending on the
tank capacity).
Step 13
v Quick Tank Fill
Open Bypass
Simply OPEN the Bypass Valve and un-ltered
water will ow directly into the storage tank.
When the tank is full, or a desired level is
reached, CLOSE the Bypass Valve. The system is
now in normal operating mode and the
optimized water will flow to the tank.
IMPORTANT: Do not leave the system in
bypass. This could result in damage to the
downstream equipment.

BWS175 Simple Install Guide 13
Open Closed
vOperation
The system operates normally when water,
under pressure, is supplied to the system.
Typical filter replacement is every 6 months
(CTOS-Q10 and ILMA-10.14). Typical
membrane replacement is every 24 months
(AMS-QT10) or less, based on water quality.
EMERGENCY BYPASS
In the event the water supply or pressure to
downstream equipment becomes inadequate
OPEN the Built-In Bypass Valve and resume
normal use of equipment. When finished using
equipment return the Valve to the CLOSED
position. DO NOT leave the system in bypass
mode for prolonged periods of time.
IMPORTANT: Leaving the system in bypass
could cause damage to downstream
equipment. If the problem persists contact
your OptiPure dealer for assistance.
Step 1
Close Feed Water Supply Valve.
OR
Be sure Bypass Valve is closed and turn
pre-lter cartridge 1/4 turn to the left .
Step 2
Close the Storage Tank Valve.

vSHUT OFF WATER TO SYSTEM
The water is now shut o and the system is
ready for lter or membrane replacement or
other maintenance.
To return to normal operation reverse these
steps.
