Your RO system may be installed under the sink, in a basement, or other location
depending on available space. It is recommended the system be installed in as close a
proximity to the faucet to ensure optimal system flow rate. If you have a water
dispenser or ice maker in your fridge, your RO system can be installed to provide the
feed water for these features but you should consult your fridge owners manual for
further information.
System Location

Guidelines for component placement are as follows:
Faucet should be placed near the sink where drinking/cooking water is normally
required. A 2" flat surface is required to mount the faucet if an existing hole for a
second faucet is not available.The thickness of the mounting surface should not
exceed 1-1/4" on the vertical or horizontal tailpiece. Refer to Figure 1.
Storage tank may be placed where it is convenient, within ten feet of the faucet.
Under the sink or in a nearby cabinet are excellent choices. If tank is located further
than ten feet from the faucet, use 1/2" tubing to reduce pressure drop. Full tanks may
weigh more than thirty pounds, so a sturdy shelf is required.
RO unit may be mounted on either side of the sink, in a cabinet or heated basement,
with nearby access to a potable, cold line and a drain.
NOTE: All components and tubing should be located in an area not exposed to
freezing temperatures or direct sunlight.
In the cabinet On the cabinetMounted on the wall
Feed water connection is accomplished with a feed water adaptor. Locate this assembly
as close to the R/O unit as possible. Connect to a potable, cold water supply line only.
NOTE: Softened water is preferred since it will extend the life of your R/O membrane.
Drain connection is accomplished using a waste water saddle valve which is designed to
fit around a standard 1-1/2" OD drain pipe. The drain saddle valve should always be
installed above (before) the drain trap and on the vertical or horizontal tailpiece. Refer to
Figure 2.

The following components make up your Reverse Osmosis
Drinking Water System:
1. PP Sediment removes larger particles such as sand, silt, and rust.
2. Coconut Carbon removes chlorine in the feed water to protect the reverse
osmosis membrane.
3. Reverse Osmosis Membrane reduces dissolved minerals, metals and salts.
During the process, harmful compounds are separated by the membrane and
the reject water goes to waste (drain).

If the sink has a sprayer it may be disconnected for faucet installation.
A pipe cap or plug will be necessary to seal the sprayer connection.
The faucet should be positioned so it empties into the sink and the
spout swivels freely for convenience. If sink has a hole that can
accommodate the RO faucet, no drilling is required. Proceed with
mounting the faucet.
Installing the Faucet
NOTES:
While there is a gasket that seals against the shut off valve, it is rec-
ommended to still use teflon tape on the tank threads to insure a good
seal is achieved. It is also recommended to check for any leaks after
the system has had time to produce water and pressurize inside the
storage tank. Failure to do so could result in a leak that is not spotted
until after the installer has left the location.

Porcelain, Enamel, Ceramic on Metal or Cast Iron Sinks
For porcelain/enamel sinks marble or granite counter tops refer to
manufacturer/Supplier for proper drilling instructions.
1. Feed the threaded nipple through
sink or counter mounting hole and
orient the faucet as shown. From
below sink or counter, assemble
the flat washer and hex nut on
threaded nipple and tighten by
hand. After checking faucet
orientation, tighten with a wrench
until secure.
2. Install the faucet adaptor fitting
(shown below) and tighten until the
fitting bottoms out on the o-ring
inside to create the seal. Tighten
with wrench until secure.
3. Insert the 3/8“ white tube into
the quick connect fitting.
Installation procedures for stainless steel sinks
Recommended tools:
·Center punch
·Variable speed drill
·High speed drill bits
·Protective gloves & eye protectors
To make the faucet mounting hole (if sprayer or second hole is not
used), check below to make sure the drill does not interfere with
anything below the sink. Center punch a small indent at the
desired faucet location. (2”flat surface is required, not exceeding
1-1/4”in thickness). Drill the 1/8 1/2”pilot hole. Drill the ”hole for
the faucet shank to fit through. Clean up sharp edges.

1. Position half of the saddle with quick connect fitting at selected
location and mark for the opening.
2. Drill 1/4”hole at mark through one side of pipe. Position both
halves of the saddle on drain pipe so quick connect opening lines
with hole.
3. Secure drain saddle clamp with bolts and nuts provided. (Do not
over tighten and make sure there is equal space between saddle
halves on each side).
When installed under a sink the unit is normally mounted to the right
or left sink cabinet sidewall. It is suggested to locate the system
where it can be easily accessed or even removed off the hanging
screws and pulled back out from the sink to change the filters.

Installing Tubing Into Fittings

1. Locate the unit in the desired position. Make sure it is at least 3"
off the floor. Level it and mark the location of mounting screws.
2. Install the screws. Leave 1/4" of the screw head out from the
wall.
3. Install the mounting bracket slots over the screws and hang the
unit.
NOTE: THE UNIT MUST BE INSTALLED BY HANGING THE
BRACKET ON THE WALL SO THAT THERE IS NO WEIGHT
ON THE FILTERS. THE SYSTEM IS NOT DESIGNED OR
INTENDED TO SIT ON THE FLOOR WITH THE WEIGHT
SUPPORTED BY THE REPLACEABLE FILTER CARTRIDGES.

See Figure 4 and 5. Check and cut the tubing end squarely and cleanly with utility
knife or scissors.
Make a 5/8”mark at the end of the tube so you will be able to confirm when the
tube is inserted fully into the fitting.
Remove the blue lock clip from the fitting with your nail. If the lock sleeve pops
out of the fitting when doing this, simply pop it back in.
Insert the tube into the fitting until you reach the 5/8”mark on the tube. You will
feel resistance when the tube reaches the small rubber O ring inside the fitting. You
will need to wiggle the tube and apply additional pressure to get it past this O ring
and create the seal. If the tube is not 5/8” into the fitting and past the O ring, no seal
will be created and leaking will occur.
Once the tube is fully inserted into the fitting, pop the blue lock clip back on the
fitting. This will lock the tube in place and prevent it from moving.

Procedure (Standard Faucet)
Sanitize the System (Recommended)
Sanitizing is recommended every 2 years after installation of the Reverse
Osmosis system. It’s also recommended after servicing inner parts. It is
important that the person installing or servicing the system have clean
hands while handling inner parts of the system.
Note: The bleach must be removed from the system before drinking
the water. See Flush System instructions on the next page.
1. Turn off the water supply to the RO system and close the ball valve on
the storage tank.
2. Open the RO faucet.
3. Use an eyedropper (not included) and common household bleach
(5.25%).
4. Add 3 ml. of bleach into open end of 3/8" tube connected to tank.
Handle bleach according to bleach manufacturer’s recommendations.
5. Connect tubing back to tank ball valve.
6. Sanitizing the system will be completed during the Flush System and
Check Operation steps on the following page.

1. Check all connections to be sure they are secure.
2. Turn on feed water valve and check for leaks. (turn off and correct
leaks if leaks occur).
3. Close faucet and wait 5 minutes to see if leaks result. (turn off and
correct leaks if leaks occur).
Start-up
1. Open faucet handle and allow tank to completely drain. Do not use
this water. (When tank is empty, faucet will steadily drip. This is the
rate the R/O system processes water).
2. Close faucet and reinspect system for leaks.
3. Allow system to process water for approximately 1~2 hours, at
which point tank will be practically full.
4. Open faucet again and allow tank to empty for a second time. Do
not use this water.
5. Wait another 1~2 hours to allow tank to re-fill.
Flush System and Check Operation
Recommended Filter Change Schedule
The following periodic maintenance is recommended so your system
will provide years of trouble-free service:
Your system contains a R/O (reverse osmosis) membrane which
should also be replaced periodically for proper operation. The R/O
membrane may require changing more frequently depending on the
source water conditions.
