5 STAGE
REVERSE OSMOSIS SYSTEM
Water Filter Tree

Thank you for purchasing the WLF-RO5 Reverse Osmosis (RO) water purification system
The WLF-RO5 is a 5 stage Reverse Osmosis system designed to reduce high amounts of contaminants found
in municipal drinking water including Sediment, Chlorine Taste and Odor, Copper, TDS, Chromium, Fluoride,
Lead, Mercury, Arsenic, Chromium, Cryptosporidium or Giardia.
Osmosis is achieved by forcing water through a semi permeable membrane allowing only pure water to
pass through. The contaminants concentrate on the other side of the membrane and are eventually
flushed down the drain.
This system has 5 separate treatment segments using 5 different filters. A sediment filter, GAC filter, carbon
block, membrane and a post carbon filter.

11
High Pressure Switch
WFT-HPS11
When the pressure in the tank reaches 2.5Kg/cm², it turns
off the power supply to the pump and the membrane stops
generating water.
12
Wastewater Flow
Restrictor
WFT-WFR12
Maintains the flow rate required to obtain the highest
quality drinking water (based on the gallon capacity of the
membrane). It also helps maintain pressure on the inlet
side of the membrane. Without the flow control very little
drinking water would be produced because all the incoming
tap water would take the path of least resistance and
simply flow down the drain line. The flow control is located
in the RO drain line tubing.
13
Flow Adjust Ball
Valve
WFT-FABV13
Manually adjusts the amount of waste water passing
through the flow restrictor
14
Drain line and Saddle
N/A
This line runs from the Wastewater Flow Restrictor to the
drain. This line is used to dispose of the impurities and
contaminants filtered by the membrane. (Saddle not
included)
15
Post Filter
WFT-P33
After the water leaves the RO storage tank, but before
going to the RO faucet, the product water goes through the
post filter through a carbon block. Any remaining tastes
and odors are removed from the product water by post
filtration
16
Storage Tank
WFT-ST16
The storage tank holds up to 2.5 gallons of water. A bladder
inside the tank keeps water pressurized in the tank when it
is full.
17
Faucet
WFT-FAU01
The RO unit uses its own faucet, which is usually installed
on the kitchen sink. Some areas have plumbing regulations
requiring an air gap faucet, but non-air gap models are
more common
Water Filter Tree

Faucet Installation
WARNING: Serious cracking and damage may occur to your sink even if instructions are
followed exactly due to age and the imperfections inherent in natural materials. Instructions
may not apply exactly to your sink. Use caution –sink may be slippery.
Note: Most sinks are pre drilled
with 1 ¼” diameter hole that you
can use for your RO faucet.
1. Locate a suitable place in your sink to install your RO faucet ⑰ and place a piece of masking tape
over where the hole will be drilled. Mark the center of the hole on the tape.
2. Drill a 1/8“pilot hole through the marked center of the desired location of the sink with a variable
speed drill set, on the slowest speed. If drilling through a porcelain sink, use a lubricant liquid soap
to keep the drill bit cool to prevent the sink cracking or chipping.
3. Using the pilot hole as a guide, drill a larger hole using a 1 ¼” diamond tip hole saw on the slowest
speed setting, lubricating as you go, to keep the hole saw cool during drilling.
4. After drilling, sand any sharp edges prior to mounting the faucet.
5. To install the faucet ⑰, feed
the hose (green on the
diagram) through the drilled
hole on the sink.
6. Before installing the faucet,
first attach the Hose
Connector, Anti-Slip Plastic
Ring and the Plastic Sleeve, to
the hose, as shown on the
diagram (Fig.1.2)
7. Slide the fixing plate and the
rubber gasket up the stud until
it reaches the bottom of the
faucet.
8. Then slide the faucet into the
hole, so the stud protrudes on
the underside of the sink.
9. Slide the plastic washer
followed by the lock washer and secure it with the nut provided.
10. Attach the Hose Connector to the end of the stud twisting counter-clockwise until is tightly secured.

Cold Water Valve Installation
Caution: Water supply line to the system must be from the cold water supply line only. Hot water will severely
damage your system.
Turn off the cold water supply to the faucet by turning the cold water
valve completely off.
Open cold water sink faucet to relieve pressure.
Attach the 3-way valve to the cold water supply ① making
sure that they are connected to the 3/8” openings.
Caution: Under sink piping can vary, especially in older homes.
If you have a brass 1/2” piping, it will require a different
adaptor. If in doubt you should contact your local plumber.
①
To make a connection, the 3/8” tubes are simply pushed into
the fitting. The unique locking system holds the tube firmly in
place without deforming it or restricting flow.
Cut the 1/4” RO tube supplied that attaches to the inlet side of
the RO pre filter ③to install the Water Shut-Off Valve ②.
This valve will help switching the supply of water to the RO
system whilst keeping supply to the main sink.

Drain Saddle Installation
Drain Saddle (Not Supplied) should fit standard 1 ¼” – 1 ½” drain pipes
Caution: If you have a garbage disposal, do not install the drain saddle near it. Installation of the drain saddle must
be either above the garbage disposal, or if a second sink drain is available, install it above the cross bar on the second
drain.
Choose a suitable location on the drain
pipe to drill the RO waste water drain
hole.
Caution: The drain saddle ⑭must be
mounted at least 1 ½” above the nut of
the P-trap or cross bar from the garbage
disposal to insure proper drainage.
Prior to drilling place a strip of tape on the
chosen location, to avoid the drain pipe
damaging during drilling.
Assemble the drain saddle around the
drain pipe. Using a screw driver tighten
screws evenly and securely on both sides
of the drain saddle.
With the drain saddle secured onto the
drain pipe, use a 1/4” drill bit installed in
your electric drill and insert the drill bit
through the opening in the drain saddle
and drill into the drain pipe.
Caution: In order to prevent damage of to
drain saddle while drilling, it’s is very
important to keep the drill centered.
Insert the 1/4” tube into the opening in
the drain saddle and hand tighten the nut
with a 1/4” wrench.
Important: When inserting the 1/4” pipe
into the drain saddle make sure is not
pushed in right to the end, as this may
prevent the water from draining properly.
