Safety Warning
■Plug the ltration unit into an electrical outlet only aer you nish the in-
stallation.
■Check if the voltage indicated on the ltration unit or power adapter corre-
sponds to the local mains voltage before you connect the appliance.
■Do not use the ltration unit if it is damaged in any way. Take it to an autho-
rized service center for repair.

Description
Congratulations on your purchase of the Prio® Expert R.O. ltration system! With proper
installation and maintenance, it will provide you with high quality drinking water for many
years.
This R.O. system removes odor and most harmful substances such as heavy metal ions and
total dissolved solids from tap water making it tasty, fresh and vital.
Please familiarize yourself with the general concept behind the product and main modes of
operation.
Key Features:
■Clean and safe drinking water right in your home. No need to transport and dispose of
bottled water any more.
■Factory-preinstalled lters and membrane for faster and easier setup.
■Filters and membrane quick-change housings for easy regular maintenance.
■Compact and beautiful design.
■Quick ttings for easy tube connections and change of lters.
■The booster pump increases pressure to radically improve the performance and eective-
ness of the R.O. unit in all three key areas: increases ltered water ow (production rate),
increases rejection rate (improves water purication quality), increases recovery rate (de-
creases amount of waste water).
■Prolongs the membrane and pre-lter(s) service life due to increased recovery rate.

How It Works:
This Prio® Expert reverse osmosis system is a multi-stage automatic ltration machine.
Reverse Оsmosis (R.O.) is a water purication technology that uses a semipermeable mem-
brane to remove ions, molecules and larger particles from drinking water. R.O. can remove
many types of dissolved and suspended species from water, including bacteria, and is used in
both industrial processes and the production of potable water.
Water supply is done through the inlet valve, ltered water is rst stored in the water tank and
then delivered through the faucet, and waste water is drained through the drain saddle. Detailed
connection scheme is shown on the following charts.
Pump:
The ltration unit is equipped with a built-in low voltage booster pump powered by the included
transformer for safe operation.
Pressure Switches:
The ltration unit is equipped with low and high pressure switches. The low pressure switch shuts
o the pump when there is no inlet water or its pressure is too low. The high pressure switch shuts
o the pump when the ltered water faucet is turned o and water storage tank is full.
Inlet Valve:
An adapter ball valve is included to be installed into the cold water supply line to feed water
to the ltration unit inlet.

5
Faucet:
Designer faucet for ltered water is included and usually mounted on the sink deck or counter-
top for dispensing the clean, ltered water from the ltered water storage tank.
Water Storage Tank:
Air pressurized storage tank is used for ltered water storage.
Drain Saddle:
Fits a standard 1.5” diameter drain pipe to drain the waste water from the drain outlet of the
ltration unit.
Pre-Filters:
The ltration unit has coconut carbon block pre-lter. It provides initial ltration of the wa-
ter and protect the following thin lm composite R.O. membrane from dirt and aggressive
chemicals such as
chlorine oen found in tap water.
R.O. Membrane:
Main stage of the ltration is R.O. membrane. It is “semi-permeable”, which means that it
allows water to pass through but prevents dissolved particles from passing through. It splits
the feed water into two streams: clean water goes to the post-lter and then onto the tank
and faucet. Waste water with rejected particles goes down the drain.
Post-Filter:
Last stage of ltration is an activated carbon post-lter and/or remineralization for ne con-
ditioning and keeping the extra freshness of your water.

Performance:
Performance of the appliance such as ltered water delivery rate, rejection rate, etc. is highly

ination, tank air pressure, etc.) and R.O. system use pattern. Actual performance may vary.

Installation
Notes:
1. Shut o the cold water supply under the sink or the location where the system will be
installed. If the existing valve is inoperable, the water supply to the house must be shut
o. Then, relieve the water pressure by opening the cold water tap. Do not connect the
system to hot water source.
2. Depending on your plumbing system and sink/countertop type you may need to use tools
like variable speed drill, drill bits, screw driver, wrench, etc. You may want to ask a profes-
sional service provider such as certied plumber to install the inlet valve adapter, faucet,
and drain saddle to assure a trouble-free setup.
3. During installation you will need to cut the supplied ¼” tubing into segments as needed.
Use your utility knife for that or similar tool. See the following charts to determine the
connection scheme and length of hoses necessary. You may need to purchase extra tubing
for far-reaching or other corner case installations.
4. Do not connect the ltration unit to the electrical supply until the setup is completed.
5. With initial operation, check for leaks. If a leak is observed, verify that the tubing is pushed
into the quick tting far enough to seal the tubing against the O-ring and that the tubing
was cut at 90°.

IMPORTANT: Cut tubing at 90° to ensure a
watertight seal:
Units Placement Guide:
Remember this unit must be serviced at regular intervals. Therefore it should be reasonably
accessible (for changing lters or membrane, etc.).
To connect the tubing to a tting:
1. Remove the lock if present (not present in self-locking ttings).
2. Push. Insert the tube rmly until full stop.
3. Pull the collet back slightly.
4. Replace the lock (if present).
To disconnect the tubing:
1. Remove the lock if present (not present in self-locking ttings).
2. Push the collet and hold.
3. Pull the tubing out.
4. Replace the lock (if present).
No skewed cut!

Installation Steps:
1. Install adapter ball valve (included) to the
cold water supply.
Use some Teon or plumbers sealing tape to
prevent leaks. Use three included threaded
adapters to make dierent connection con-
gurations (see chart for details).
2. Create ½” hole for the ltered water faucet and install it.
Tip: If you have a soap dispenser or a water
sprayer in an existing hole you may remove it
and use its hole for the ltered water
faucet.
3. Install drain saddle.
t
The square foam gasket with a circle cut out must be applied to the inside of the drain sad-
dle. Remove sticky tape backing and stick to the drain saddle as shown.
