Model: WLF-RO5

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 differentfilters. A sediment filter, GAC filter, carbon block, membrane and a post carbon filter.

Description

Cold Water Valve

WFT-CWV01

Valve that fits onto the cold water supply line. The valve has a tube that attaches to the inlet side of the RO pre filter. This is the water source for the RO system.

Water Shut-Off Ball Valve

WFT-

WSOBV02

Shuts off the mains water supply to the system

Clear Filter Housing

WFT-CFH03

Housing for the Sediment Filter

Low Pressure Switch

WFT-LPS04

Turns off the flow of water when water tank is full, switching off the pump

White Filter Housing

WFT-WHG05

Housing for the GAC Filter

White Filter Housing

WFT-WHC06

Housing for the Carbon Block

Shut-Off Solenoid Valve

WFT-SOSV07

When the system isn’t being used it shuts off the mains water supply

Booster Pump

WFT-BP08

(24V-20W) Increases Water Pressure to the RO membrane

RO Membrane

WFT-M50

Removes contaminants such as calcium and magnesium that cause hard water as well as mineral salts, heavy metals such as lead, agrochemicals, protozoan bacteria, parasites, industrial chemicals and organic debris

Pressure Gauge

WFT-PG10

Measures the system’s operating pressure

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.

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.

Flow Adjust Ball Valve

WFT-FABV13

Manually adjusts the amount of waste water passing through the flow restrictor

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)

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

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.

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 ③ to 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 ⑭ must 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.
