Pre Installaon Precauons
• Locaon of the RO system, water supply, and drain - Using the diagrams on page 6, make sure there is adequate
space for the system, the tank and there is access to the cold water supply and drain
• Locaon for the Air Gap Faucet - Refer to page 10 to make sure you understand the locaon and installaon
requirements of the air gap faucet that came with the system.
• Water Quality - In order for the system to funcon properly it is important to make sure that the feed water is
within the parameters shown below in the applicaons and operang parameters table. Operang the system
outside of these parameters will negavely eect the system’s performance as well as the longevity. Pretreatment
may be necessary to allow the system to work properly.
• Water Pressure - The reverse osmosis process requires adequate feed pressure to overcome the natural funcon
of osmosis. The minimum feed pressure should be 40-50 psi. If level of Total Dissolved Solids (TDS) is over 500 in
the feed supply a booster pump is highly recommended.
• Electricity (if Needed for a booster pump) - If a booster pump is necessary, make sure you have an outlet in the
cabinet to plug in to.
• Pre and Post Filters - To save shipping space, they have been loaded into the lter housings but are sll shrink
wrapped. Unscrew the housings, remove the lters and remove the shrink wrap before loading them back into the
housings.

Reverse Osmosis System and Component Introducon
Permeate Pump
Remineralizaon Cartridge
Automac Shut-O Valve
Your new Reverse Osmosis Drinking Water System (RO) uses a combinaon of ltraon and membrane technologies
and eciency components to provide the highest quality water possible. The following components combine to give
you high quality water in the most ecient way possible.
Pre and Post Filtraon
The rst stage is a 5 micron acvated carbon block, the pre-lter. Designed to reduce
chlorine that may be present to protect the membrane as well as eliminang taste
and /or odors. Another 5 micron acvated carbon block is the post lter in between
the storage tank and the faucet to give the RO water a fresh pass through carbon
before it goes into your glass.
Reverse Osmosis Membrane
The RO Membrane is the heart of the ltraon system. It is designed to reduce the
dissolved mineral content of the water. Minerals picked up in the environment by the
water are measured as Total Dissolved Solids (TDS). In the Reverse Osmosis process,
dissolved minerals are separated from the incoming water (Feed Water) to produce
the product water (the Permeate). The excess minerals are rinsed to drain (the Reject
Water).
The membrane is a specially constructed, fully aromac polyamide lm and is
classied as a Thin Film Composite (TFC) The spiral wound construcon of the RO
Membrane provides maximum surface area for water producon and is less
suscepble to fouling by parculate maer, turbidity and colloidal materials.
This component provides the system eciency that most RO systems do not possess.
The Permeate Pump is a simple, yet revoluonary, device. Powered only by the
hydraulic energy of the reject water usually lost to the drain (i.e. no electricity
required), the Permeate Pump forces product water into the storage tank, reducing
membrane back pressure and maximizing available feed pressure. These pumps
dramacally improve the eciency of RO water producon, reducing wastewater by
up to 80%. It also enhances water producon and water quality from the membrane.
That means it will ll the tank faster and the water will be a higher quality!
The ASO Valve senses when the Holding Tank is full and closes the feed water supply. This
prevents excess reject water from going to drain when the unit is not producing water. This
device, used in conjuncon with the permeate pump makes this system one of the most
ecient available.
Water directly produced by the membrane travels through the ALKAline re-mineralizaon
cartridge. This increases water alkalinity through exposure to re-mineralizaon media boosng
the water’s pH and increases benecial mineral content.

Installaon Notes:
Under a standard sink base cabinet is usually plenty of room for the water system. The airgap faucet and drain
installaons are described later In this manual. The RO system is best mounted to the side wall of the cabinet with
about 3” of clearance to the cabinet oor to make it easier for lter changes.
There are ve tubing connecons to make once the locaon has been determined;
• The feed supply line connects the feed supply adapter (page 11) to the front of the prelter on the right. (1/4”
yellow tube)
• The tank line connects the tank valve with the tee located behind the post lter (3/8” white tube)
• It is best to aach all of the tubes to the faucet prior to installing it. Then feed the tubes down through the
installaon hole for the faucet. Finish the faucet mount and connect the tubing to the following:
(1) - 1/4” Red tube goes on the small barb on the faucet base and connects to BRINE OUT port
(2) - 3/8” Blue drinking water line connects to the stem of the faucet and the outlet port of the post lter
(3) - 3/8” Black tube goes on the large barb under the faucet base and connects to the drain saddle. This
run must be as straight as possible without dips or bends.
Tip: To make it easier to push the tubes onto the barbs, pour a cup of near boiling hot water and soak the ends of
the red brine tube and the black tube in the hot water for a few minutes. This will soen the tubing enough to
smoothly slide on to the barb. As the tube cools it will conform to the barb for a beer t.

Locaon and Installaon of the Drain Saddle
Here are a few ps to use when deciding the locaon and installing:
• Place the drain saddle as far away from a disposal as possible. A disposal can shoot debris into the drain
line and block the air gap. Locate a place where tubing can run as straight as possible without looping or
extreme bending.
• Adjust excess tubing that dips below the saddle locaon that causes water to back up the air gap and leak
out.
• Keep the drain saddle from rotang away from the drilled hole. Here's how: apply the clamp, ghten it,
then drill the hole. Be careful not to damage the tube connecon ng. Rotaon can also occur over me
if your system under the sink gets bumped.
• Use a horizontal mount to minimize the gurgling noise your RO system makes while ltering water. The
locaon of the saddle drain may also help.
• Never posion on the wall side of the P-Trap. The P-Trap is there to keep sewer gas from coming out your
sink drain. Placing the saddle on the back side of the p-trap will allow the sewer gas to come out the airgap
hole!
Clear accumulated debris by taking the tubing apart from the saddle. During the cleaning process, make sure
the hole is properly lined up with the clamp. Insert a pencil or small screwdriver through the ng to ensure
proper alignment.

Installaon Guide 6/29/2023 11
Drain Saddle Installaon Steps
1. Posion the drain saddle in the desired locaon, mark the
spot to be drilled and remove the saddle.
2. Drill a 7/16” hole through just one side of the drain pipe.
3. The drain saddle comes with a self adhesive foam pad. Peel
o the backing and apply to the inside of the saddle with
the tube connecon ng.
4. Aach the saddle parts around the pipe being sure to line
up the drilled hole with the saddle port. (hint) place a
pencil through the saddle’s hole and into the drilled drain
line as you ghten the parts together with the two bolts.
5. The 3/8” tube from the air gap faucet will connect to this
part. Trim it to t so that the run from the faucet barb and
the drain saddle is as straight as possible.
Note: This adaptor is designed to t 3/8” compression supply threads and
has adapters for 1/2” NPS connecons
1. Locate the cold water supply valve (shut-o) under the sink. Turn o the
cold water supply.
2. Turn on the kitchen faucet. This will release pressure and allow water to
completely drain from the line.
3. Disconnect the cold water feed supply line from the top of the cold water
supply valve. (Angle stop valve)
4. Holding the Angle Stop Valve Adapter in an upright posion, thread the
female side of the faucet adapter on to the cold water supply valve.
5. Aach the cold water supply line for the faucet to the male - top side of
the adapter.
6. Occasionally, The adapter will have to be located at the base of the base
of the cold water side of the sink faucet and the reason for the 1/2” NPS
adapters.

Air Gap Faucet Installaon
Installaon of the Air Gap Faucet is a required part of installaon and is the system's means of drain water backow
prevenon. If sink top includes an unused knockout hole, remove knockout cover plate and mount faucet there. If no
knockout hole exists, drill 1.25" diameter mounng hole in sink top using 1.25" hole saw and drill motor. Sink
material will determine drilling method. Faucet should be posioned so it empes into sink and spout swivels freely
for convenience. Before drilling mounng hole, check underneath sink to ensure nothing will interfere with Air Gap
Faucet plumbing such as reinforcement ribs, support brackets, or other under-sink construcon.
CAUTION: To prevent eye injury, safety glasses must be worn during sink drilling operaon.
• Review components shown in Air Gap Faucet diagram (Figure 2).
• Aach the tubing to the faucet . Red 1/4” tubing and black 3/8” to the barbs under the faucet base and the blue
3/8” tube to the faucet adapter on the stem. Make sure the hex nut is on the stem above the adapter rst.
• From above sink/counter-top, feed tubing and remaining mounng hardware on faucet stem through the 1.25”
diameter mounng hole
• Posion faucet spout over sink
• Loosen hex nut further and insert the sloed washer between the white spacer and underside of the counter.
Place the open side of sloed washer towards air gap tubes.
• Aer rechecking the faucet orientaon, ghten the hex nut with a 9/16” wrench unl the faucet is securely
mounted.

Final Tubing Connecon
With all system components now properly installed, nal tubing connecon can be completed.
This product is ouied with user friendly “Push-In” connectors. Proper use of “Push-In” connectors is shown in Figure
9. Tubing selected for use with connectors should be of high quality, exact size and roundness, and have no surface
nicks or scratches. If it is necessary to cut tubing, use tubing cuer tool or sharp razor knife. Make clean square cuts on
ends of all tubing. Should a leak occur at a “Push-In” connector, the cause is usually the tube is not pushed in far
enough or the end of the tube is compromised.
To remedy leaks at push in connecons:
• Make sure the tubing is pushed all the way in. If uncertain, measure
3/4” and mark the end of the tube. It is pushed in all the way if the
line disappears into the ng:
• If tubing is in far enough and sll leaks, check to make sure there are
no deep scratches and the end of the tube is smooth. If not, cut back
1” nice and square and re-insert
3/4”

How to Use Quick Connect / Push to Fit Fings
To Install:
• Cut tubing Square - Remove burrs and sharp edges. Ensure the outside
diameter is free of scratches.
• Push the tube into the ng all the way to tube stop. (measure 3/4” up
tube and make a line. Push tubing in so that line is even or below the collet)
• Pull to check it is secure and test the system for leaks before use
To Disconnect:
• Ensure the system is o and depressurized, push the collet square against
the ng body. With collet held in this posion, the tube can be removed

System Start-up
System Roune Maintenance
1. Check all connecons and ensure they are secure.
2. Turn on the feed water valve and check for leaks. (Turn o and correct leaks if any
occur)
3. Close the valve on the storage tank and open the faucet unl a steady fast drip or
stream of water ows. (The higher the selected membrane output, the more
water will ow) Water will be owing to the drain as well. NOTE: The permeate
pump will not start working unl the tank valve is opened and the tank reaches 7
psi.
4. Once there is a steady fast drip or stream of water coming from the faucet, close
the faucet and wait ve minutes to see if any leaks result on the system. The inial water from the system may be
slightly discolored. This is normal.
5. If there are no leaks, open the storage tank valve and allow the system to ll. Most systems will be full within 2-3
hours depending on feed pressure, membrane output, and tank size. The system is full when the water to the
drain stops. Check for leaks with the system full and repair them accordingly. NOTE: When the system is rst
turned on, water may intermiently "spurt" from the air gap opening on the side of air gap faucets. This is
common and should correct itself aer the air is purged from the system. CAUTION: Ensure that the system is not
being fed with water above 75 PSI or damage to the system could occur.
Periodic maintenance is needed on any water ltraon appliance. The PRO-41000A is equipped with lters, a
membrane and a remineralizaon cartridge that will all require replacement from me to me to ensure that the
system connues to produce very high quality water.
Filter life is dependent on water usage as well as water condions at the installaon site. Carbon lters have a denite
exhauson point. With a family of four with frequent use, the carbons and remineralizer should be replaced every six
months. A smaller family with less frequent use replacing them annually may be sucient.
Membrane life will be extended if water is soened rst. Non soened water will shorten replacement cycles but
typical membrane life is 2-3 years before needing to be replaced.

System Roune Maintenance
Periodic sanizaon of the storage tank is an oen missed step in the overall maintenance of reverse osmosis systems.
We have created a kit made up of 4 thumb latch style quick disconnect ngs to make the process of sanizing
incredibly easy so the step will not be missed.
The Kit consists of 4 ngs, a packet of Sani system, a tank pressure gauge, and a plasc syringe.
Once the ngs are installed, sanizing the tank takes just a few minutes and during lter change outs, specically
membrane change outs the tank sanizaon process is so simple it makes good sense to get it done. The tank pressure
gauge allows you to keep track of the empty tank precharge pressure to ensure proper tank funcon.

Tank Sanitaon Kit for PRO-41000A RO Systems
1. Close the feed supply valve
2. Close the tank valve
3. To relieve pressure, open the RO faucet unl
water ow stops
4. Cut tubing from feed line
5. Install valved insert (1) closest to feed supply
valve
6. Install body (3) closest to the RO inlet
7. Cut tubing from tank line
8. Install body (4) closest to the tank valve
1. Close feed supply valve to the RO unit and
open RO faucet to allow all water to empty
from the storage tank.
2. Close tank valve and disconnect the body (4)
from the non-valved insert (2). Shake as much water as you
can from the tube.
3. Fill the syringe with the liquid sanizer and empty it into the
coupling body (4) so that it enters the tank through the
tubing.
4. Connect the body (4) to the valved insert (1).
5. Open tank valve and feed supply valve and allow the tank to
ll for several minutes. If using Sani System, you only need to
let the water sit for 60 seconds once the tank is full.
6. Close the tank valve. Reconnect the couplings to their
original posions, install valved insert (1) to body (3), and
non-valved insert (2) to body (4). Then open the RO faucet to
empty the tank.
7. Close the RO faucet and allow system to ll the tank. This
should take 3 to 4 hours.

Troubleshoong
Not Enough Water From The Storage Tank
Possible Cause Soluon
Feedwater valve is plugged or closed. Open valve or unclog.
Pre or post lter is clogged Replace lters
Low feed water pressure Water pressure should be above 50 psi. Install a booster pump
RO Membrane is fouled Make sure drain line is not clogged. Correct fouling cause, replace membrane
Air pressure in storage tank is not correct Empty water from tank. Adjust empty tank precharge to 5-7 psi
Air bladder in tank has failed Replace the storage tank
Tank valve is closed (o) Open the valve
Drain ow is too high Check that ow restrictor is correct for the membrane - replace restrictor
Possible Cause Soluon
Air Pressure in storage tank is incorrect Open faucet and empty water from storage tank. Shut o feedwater to the system
and remove the tank from under the sink (much easier to work on)
Locate the air valve and add air. If there is sll water in the tank, connue to add
air unl the water is out. Once water is out adjust the empty tank air pressure to 5-
7 psi. Reinstall the tank under the sink and turn feedwater back on an allow the
tank to ll
Carbon post lter is clogged Replace lter
Tank valve is parally closed Open valve all of the way
Low water producon See secon above on not enough water from storage tank
Low Water Pressure from Drinking Water (RO) Faucet
Poor Water Quality - High TDS, Bad Taste or Odors
Possible Cause Soluon
RO Membrane is expended If membrane life is unusually short, nd and correct the problem. (High hardness,
iron or manganese in the feed water) Avg membrane life is 2-3 years. Replace the
membrane.
Low feedwater pressure Water pressure should be 50 psi or beer. Add a booster pump
Pre lter clogged prevenng good pressure Replace the lter
Dissolved gas in feedwater (Roen egg smell) Well water - Pretreat feedwater to remove gasses
Change in feedwater quality - Worsens Pre-treat issues
No water moving to drain Drain ow restrictor is clogged - replace it
Drain water coming from Faucet air-gap
Possible Cause Soluon
Drain line is clogged Clear or replace tubing - check that drain pipe is clear
New Install Too much tubing used from airgap connecon to drain line (see page 10)
