REVERSE OSMOSIS WATER PURIFIERS
Of all methods that purify drinking water for domestic use, the process of REVERSE OSMOSIS
is the most advanced, economical and effective. REVERSE OSMOSIS has the ability, unlike
conventional filters, to remove contaminants such as dissolved solids and all other impurities.
The REVERSE OSMOSIS (RO) process works by forcing water under pressure through a
special TFC Membrane. The membrane has the astounding quality of attracting water
molecules and repelling dissolved impurities, even those smaller than the water molecules
themselves.
The REVERSE OSMOSIS (RO) purifiers remove all the contaminants of concern to the
consumer such as bacteria, viruses, parasites, heavy metals, inorganic chemicals, pesticides
and algae.
RO purifiers flush the impurities down the drain rather than collecting them in the filters, as is
the case with ordinary systems, preventing any build up within the system.
Also RO systems oxygenate the water giving it a lively fresh taste, unlike distilled water, which
may have a flat dead taste.
With REVERSE OSMOSIS, you can be rest assured your drinking water is of the highest quality
possible and the best possible investment for your families’ health.
HOW DOES IT WORK?
Polluted water is forced by mains water pressure against a semi-permeable membrane.
Purified water molecules easily pass through the membrane while pollutants, typically being
larger than the pores ( .0005 of a micron in size), cannot pass through and are washed away.

INSTALLATION
Preparation
Check the following list of components to
ensure that all parts are packed with your
system
1 – Storage Tank
1 – RO System
1 – RO Water Faucet
1 – Installation Kit
Determine the location for the installation of
the RO system. Avoid locations where the
system might come in contact with hot water
pipes or other hazards, taking into
consideration ease of maintenance.
Determine the location for the faucet.
Check to see that drilling the faucet hole
will not damage pipes or wires running
underneath the sink.
Determine the location for the storage tank.
A maximum distance from tank to faucet of
4 metres (12 feet) is possible. The system
will produce a faster flow at the faucet with
the shortest tubing run from tank to faucet.
All tubing is colour coded for ease of installation.
1/4” Blue – Connects the feed water valve to the RO pre-filter.
1/4” Yellow – Connects the RO membrane product port to the storage tank.
1/4” Black – Connects the membrane brine port to the drain connector.
1/4” White – Connects the post-filter to the faucet.
Page 4
Fittings and Tubing
Hose Quick Fit Connect fittings are used
throughout the system.
To ensure an
optimal seal, tubing should be cut with the
end square. An angled cut or distortion of
the tubing may not provide an efficient seal
and could cause leaks.
To install, push tubing into Quick Fit
Connector until it bottoms out (approx
5mm). Pull tube back 2 mm and the collet
will slide out with the tube, then push firmly
a second time until tube stops.
NOTE: To disconnect, push collet against
body of Quick Fit Connector, then slide tube
out of fitting.

Important: Use Cold Water Only!
1.
Installing Your Filter
Find a convenient location for the filter under the bench. Take into consideration ease of
maintenance [e.g. cartridge replacement & best use of cupboard space]. Attach the filter
to the cupboard wall, allowing height for changing cartridges. The system will operate
without problems laying on it’s back.
2.
Shut off the Water
Locate the water shut-off valve for the cold water feed line you have selected for your
water supply. Accidentally hooking up the system to the hot water supply line will
permanently damage the membrane. To assure you are using the cold water line, turn
on both the hot and cold-water faucets. After the water is warm to the touch, feel the
pipes under the sink. It will be easy to identify the hot and cold pipes.
Close the cold water shut off valve. Turn on the cold-water tap only to assure that the
line is completely shut off and drained. If there is no cold water shut off valve located
under the sink, then turn off the main water supply at the entry to the house.
3.
Attach Plumbing Kit Assembly
The mains connection best suited to your installation will have been selected at the time
of ordering, Separate instructions are supplied with the kit.
USE THREAD TAPE SUPPLIED ON JOINTS
Important: Use Cold Water Only!

4.
Installing the Drain Outlet Clamp Assembly
Select a location for the drain clamp above the ‘S’ Trap but not more than 40mm above
the normal water level or the best location is on the transfer pipe between twin bowl sinks
if you have one. Position the drain outlet clamp on the drain pipe. Allow adequate space
for drilling. Tighten Clamp with “Tightening Screw”
Using the opening in the drain outlet clamp, drill a ¼” hole in the drain pipe. Clean debris
from the clamp. Reattach tube Connector.
NOTE: Locate the drain connection away from the garbage disposal to prevent
potential contamination and system fouling.
Important: Use Cold Water Only!

6.
Place a piece of masking tape or duct tape on location where the hole is to be drilled. Mark the
centre of the hole on the tape.
Using a variable speed drill on the slowest speed, drill a 1/8” (3 mm) pilot hole at the centre of the
desired location. Use lubricating oil or liquid soap to keep the drill bit cool while drilling.
Enlarge the hole to ¼” (6 mm). Keep the drill speed on the slowest speed and use lubricating oil
or liquid soap to keep the drill bit cool.
Enlarge the hole to 7/16th to ½” (11 to 13 mm) Keep the drill speed on the slowest speed and use
lubricating oil or liquid soap to keep the drill bit cool.
Pass the Escutcheon plate (chrome washer) and large black washer over the threaded mounting
tube at the base of the faucet.
From top of sink, slide the threaded mounting tube through the hole drilled in the sink. Align the
faucet body.
From under the sink, slide the smaller rubber washer on the threaded part of the faucet first, then
the plastic washer, locking washer and then the thin threaded nut, Tighten with a spanner.
Holding the tube from the filter system, place the brass cup nut on first, then the nylon olive and
then insert the nylon thimble into the end of the tube as far as it will go. Insert the tube into the
base of the threaded part of the faucet, push it in firmly (about ¼”) and slide nut up to thread and
tighten firmly, do not over tighten.
Storage Tank
Place storage tank in a convenient position. Tank can be placed on its stand, either
upright or on its side.
7.
Activating the System for the First Time
IF CONNECTING SYSTEM TO ESPRESSO MACHINE: Do not connect White Supply
line to machine until after system is purged. Allow water from White line to go down sink
or into bucket.
Slowly turn Feed Water Valve counter clockwise until fully open. Check plumbing kit
assembly for leakage.
Make sure all water supply/drain lines are secure and free from leakage.
Turn storage tank valve one quarter turn counter clockwise to open the valve [the handle
should be in line with the tubing as it enters the connection]
Open the membrane flushing valve until water is freely flowing down drain then close
Open the RO water faucet and let the water flow until all the air has been expelled from
the system. Water will be slightly discoloured [non-toxic carbon fines] and have some
aeration.
One air has purged turn off system and connect system to Espresso Machine.
Page 7
Turn system back on, Close the RO water faucet. In 15 minutes, check the connections
for leaks and correct if necessary.
8.
Connecting the System to Espresso Machine
It is best to use the brass ½” Male to ½” Male half union adaptor supplied as this makes
the best seal on the ¼’ pipe to thread (On end of White pipe) This Plastic pipe to thread
adaptor has an “O” ring in it and if leaking tighten slightly.
Connect machine to brass adaptor on end of white hose.
Purge water through machine to remove air bubbles trapped in system.
Do Not Use the First Reservoir of Water
Allow the reservoir to fill for 1 to 2 hours. Dispense this water to sink. This
process removes the factory installed sanitising solution from the entire system
and sends it to the drain. Repeat this process one more time. Allow the tank to
fill for 1 to 2 hours and dispense this water to the drain.
Allow to refill for 1 hour and system is ready to use.

Maintenance – Imperative to follow the sequence as outlined
1) Open RO water faucet and let the water run until empty.
2) Turn Feed Water Valve Off.
3) Turn off Storage Tank Tap. [on top of tank]
4) Remove the Sediment cartridge. Simply turn the Sediment cartridge housing tub clockwise
and remove the filter from within.
5) Remove the Pre-Carbon cartridge. Simply turn the Pre-Carbon cartridge housing clockwise
and remove the filter from within.
6) THIS STAGE ONLY TO BE DONE EACH 3 – 5 YEARS. DISREGARD AT OTHER
SERVICE INTERVALS.
The membrane is contained within the horizontal tube clipped to the mounting bracket with 3
tubes attached. Remove the tube from the end with the single tube and undo the large cap
nut from the end. Prise membrane out without damaging the membrane housing, insert new
membrane and re-assemble, be sure to push the membrane firmly into it’s housing.
7) Remove the Post-Carbon cartridge. Omnipure CL10RO-T40, remove the John Guest fittings
and install these into the new cartridge with a small amount of plumbers thread tape.
8) Install the sediment pre-filter by installing the cartridge into the housing tub and threading the
housing tub back onto its housing head the by turning anti-clockwise, do not over tighten.
9) Install the carbon (chemical) pre-filter by installing the cartridge into the housing tub and
threading the housing tub back onto its housing head the by turning anti-clockwise, do not
over tighten.
10) Turn Feed Water Valve ON with the faucet open, run system for 15 minutes, water will run
very slowly. Water will be slightly discoloured [non-toxic carbon fines] and have some
aeration.
11) Close RO water faucet and open Storage Tank Tap.
12) Flush 1 litre of water through prior to using system.
When away for extended periods, turn water off
This unit is fitted with a membrane-flushing valve and is normally closed. About once a month turn the
small red stop valve at the front of the unit to the open position and leave it on for about 10 minutes to
clear any possible build-up of particles, failure to do this will shorten membrane life. This flush valve
needs to be operated when the tank is filling, if you open the valve and nothing happens the system is in
shut down mode, release some water from the faucet to start the unit filling again and open the flushing
valve again. Drain the tank as part of the membrane flushing process.
Page 10
This unit is fitted with a re-mineralizing cartridge, it weight when new is 1200 grams and when
exhausted will weigh around 300 grams. If you detect a change in the taste of the water remove
this cartridge and weigh it, it is also a good idea when changing the sediment and carbon
cartridges to weigh it then. The life of this cartridge is determined by the PH level of the water
exiting the membrane and will vary from location to location.
