Correctly maintained, the RO300 will provide many years of
reliable service.
Before you start installation:
1. Water pressure at the installation point should be minimum 350kPa or the RO performance is compromised. Speak
with WFS if mains water pressure is less than 350kPa.
2. Space required; The R.O. assembly requires 500mm high (allowing for cartridge change out) 330mm wide and
140mm deep. The space required often requires any existing shelf to be modied or removed.
3. The storage tank used with the RO300 measures 350mm high and 280mm in diameter and should be located near
or within 2 meters from the RO300.
4. Tools required;
For stone benchtops: we recommend contacting a benchtop company or suitably qualied tradesperson to drill the
stone benchtop.
For stainless steel sinks/laminate benchtops, you will require:
1. Power drill and drill bits
2. Phillips head screwdriver
3. Adjustable wrench
4. Hammer and center punch
Installing the Faucet
1. Ensure the faucet location is suitable for your kitchen. A 2” diameter foot print is required
2. Mark the centre with centre punch for the 1/4” pilot hole.
3. Drill the pilot hole.
4. Continue to enlarge hole with larger size drill bit until it is 1/2” (12mm).
5. Clean up any sharp edges.

Mounting the Faucet: FIGURE A
1. Chrome base plates and the rubber washer
slide up the shank to the faucet body.
2. Feed threaded shank through the sink/
benchtop hole and orient the faucet. From
below sink, slide lock washer and hex nut
over threaded shank and tighten with a
wrench.
Note: It is best to have someone hold the
faucet from above the sink to keep it from
moving out of place when tightening the
nut.
3. Fit the faucet connector to the base of the
shank

R.O. Unit and Tank Installation
Drain Clamp Installation: FIGURE B

The R.O. unit is normally mounted to the right or left sink cabinet sidewall, depending on where supply tank is to be
located. Generally the unit is installed at the front of the cabinet and the tank at the rear.
To mount the unit, elevate it at least 75mm off the oor, level it and mark the location of mounting holes needed. Drill
hole for mounting screws and install screws allowing the mounting bracket slots to slip over them.
Locate the tank in a suitable location under the sink.
RO300 Tubing
BLUE 3/8” From – Product water from R.O. tank To – Faucet or point of use
WHITE 1/4” From – Cold water supply To – Inlet LHS of pre lter to R.O.
YELLOW 1/4” Supplied water to and from tank.
BLACK 1/4” From – Waste outlet of R.O. membrane To – Drain Connection.
A Drain Clamp is used to make a wastewater connection with the drain under the sink, which is designed to t around
a standard 1-1/2” OD drainpipe. The drain clamp should always be installed before (above) the p-trap and on a vertical
or horizontal drain. Do not install the drain clamp near a garbage disposal to avoid clogging the drain line with debris.
1. Position the drain clamp at selected location and mark for the opening.
2. Drill 1/4” hole at mark through one side of pipe.
3. Position the drain clamp on the drain pipe so the opening aligns with drilled hole. Use a small drill bit to verify that drain
clamp is properly aligned.
4. Secure drain clamp rmly onto the drain pipe.
5. Connect the black drain line of the R.O. into the attached drain clamp assembly.

Upon installation of the RO300, it will take up to one hour
for the tank to ll and the RO300 drain system to shut off
(drain ow to stop)
We recommend draining the rst full tank of R.O. water to
ush the tank and tubing. After this the water will be ready
for use.
Note: If the cabinet sidewalls are not solid, unit may sit on
the oor with screws used just to keep it against the cabinet
in a vertical position
Fit the 1/4” ball valve (speedt) to the top of the tank (use
Teon tape). Do not overtighten.

Ball Valve and Tubing Installation: FIGURE C

The grey inlet adaptor provides a simple, easy connection between the cold water shut-off and the cold water line.
1. Shut-off the cold water supply by using the existing shut-off valve or stop cock, located under your sink. Leave the water
supply off until installation is complete.
2. After shutting off the valve, turn on kitchen tap on the cold water side, this will relieve any excess water and ensure water is
off.
3. Using an adjustable wrench, disconnect the 1/2” braided SS hose line from the cold water shut-off valve.
4. Connect the grey inlet adaptor to the male thread on the cold water shut-off valve. Do not overtighten
5. Reconnect the braided SS braided hose to male thread of the grey adaptor.
6. Connect a length of the 1/4” white tubing between the grey adaptor and the inlet of the R.O. unit.
7. Cut into this line the small quick connect ball valve (turned off) and the pressure limiting valve (PLV).
1. Tubing should follow contour of the cabinets.
2. Cut tubing to correct length using tube cutter provided.
3. Make sure there are no crimps in the tubing.
4. Keep tubing from the R.O. unit to the tank and faucet as short as possible for good ow.
5. Connect blue tube from R.O. to tap connector (or point of use)
6. Leave the yellow tube to ow to atmosphere into a small bucket – so all air is purged through the system.
The isolating valve or stop cock of the mains cold water line can be turned slowly on. The main faucet on the sink will
ow and can now be turned off. The ball valve in the white plastic 1/4” tube should be turned on (tap to run in line with
tube, this is the ON position). Check for leaks. Water will now ll the RO300 and eventually water will slowly discharge
from the yellow tube. When water appears from the yellow tube, t the yellow tube into the ball valve connected to the
top of the pressure tank. The tank will take some time to ll. When the tank is full, water will stop discharging to the
drain. When the faucet is open – or point of use dispenser is used, the RO water will ow from the tank under pressure.

Troubleshooting
Membrane
Spare Parts
R.O. Systems are highly sensitive to pressure and temperature. The majority of problems with R.O. Systems are
a result of low pressure. The effects of low pressure include water constantly running to the drain, slow water
production and low water volume available in storage tank. In these cases where low pressure exists, a booster
pump will be required.
To troubleshoot a poor performing R.O. System, an accurate measure of the pressure and temperature of water will
be required. This will require a pressure gauge to determine exactly what the water pressure is that is feeding the
membrane.

How to make a Quick-Connect Connection
The RO300 is tted with a 75US GPD membrane (280 litres per day). Depending on your water pressure and
temperature the production will be 9-12 litres per hour.
