									                      Fitting Instructions for Undersink Reverse Osmosis System

This unit is suitable only for connection to a pressurised, chlorinated (sterilised) cold water supply. A
non-sterilised supply, such as tank water, may be of unknown quality and may contain dangerous
bacteria, viruses and other micro-organisms. To ensure freshest and best tasting water, it is a good
policy to run the faucet for a few seconds before you collect the water to drink.

Please use a skilled installer
Damage caused during installation can void your warranty. Find an installer who is prepared to
guarantee his workmanship.

How long should my cartridges last?
Purifiers are designed to remove pollutants, otherwise why would you buy one! The pollutants are
trapped and stored in the cartridges, and whatever style of cartridges, (or the claims made by some
salesman), they will eventually reach saturation point and will “unload” the pollutants. This is
generally accepted to be at around 2,000 litres or 6 months, based on average consumption. The
membrane should be cleaned and sterilised every 12 months by an authorised installer. This should
ensure at least a 3 year life span.

When replacing your cartridges
When you replace your cartridges, it is good housekeeping to sterilise the housings and tubing. Make
up a solution of cleanser (e.g. Napisan) and use a bottle brush to clean the sump of each housing and
the membrane vessel. To sterilise the tubing, first fill the housing with the cleanser (without the
cartridge fitted), screw on the base and flush through with tap water. After about 5 minutes unscrew
the sumps and fit the new cartridges. A housing spanner has been included for your convenience.

                   Fitting Instructions for Undersink Reverse Osmosis System (cont.)

Fitting Instructions
     1.       Drill a ½” hole in the rear left or right hand corner of the sink bowl and install faucet.
     2.       Position the bracket screws on the inside wall of the cupboard and attach the purifier by
              the bracket.
     3.       Wrap thread tape on all male threads of all push fit connectors and then screw into the
              ends of the filters.
     4.       Connect the tubing to the faucet (using nylon compression olive) and then follow the flow
              diagram to connect other tubing.
     5.       Fit the multi-function valve to your isolation tap.
     6.       Drill a ¼” hole in your sink drain pipe and attach the drain clamp.
     7.       Connect the drain water tube to the drain clamp.
     8.       Turn on the water supply (check for leaks) and run the purifier until water runs from the
              tank supply tubing, using a bucket to collect the water (this may take up to 20 minutes).
     9.       Turn off the water supply.
     10.      Screw the ball valve supplied into the accumulator tank.
     11.      Push the tank supply tube into the female push fit fitting in the ball valve.
     12.      Close ball valve on tank.
     13.      Open faucet by lifting lever up, turn water supply back on, and run for at least 2 hours to
              flush preservative out of the membrane.
     14.      Close faucet.
     15.      Open ball valve on accumulator tank and allow unit to run 2-3hours to fill tank.
     16.      After 2-3 hours, open faucet on the sink, and completely empty tank.
     17.      Allow 2-3 hours to re-fill tank.
     18.      You may now drink your refreshing, pure water!

Important note
PLEASE EMPTY THE TANK REGULARLY – To maintain the highest levels of purity and quality,
open the faucet and completely drain the tank. Allow 2-3 hours to refill.

As your purifier cannot be pre-tested, the responsibility must always lay with the installer to check the
tightness of all fittings and connections, after the unit is subject to line pressure. Small drips may not
become apparent for some time after installation as considerable pressure fluctuations may occur,
especially at night. It is therefore the responsibility of the installer to advise the consumer that the
installation must be checked for leaks last thing at night and first thing in the morning to make sure
there are no drips from inadequately sealed connections, as any damage would not be covered by the
              Fitting Instructions for Undersink Reverse Osmosis System (cont.)

                Trouble Shooting Guide for Reverse Osmosis Systems
1.       Use only potable water.
2.       Make sure the line inlet pressure is no less than 40 psi average and 150 psi max.
3.       Make sure that the supply can be isolated before servicing.
4.       Clear enough room for the tank and unit. RO can be placed on its side or stood upright.
5.       Up-end unit on installation or after servicing to remove air bubbles.
6.       Make sure that the valve on the top of the tank is in the on position whilst unit is running.
7.       Make sure the isolation valve on the inlet side is in the on position whilst unit is running.
8.       Check for any crimped tubes or sharp bends in tube.
9.       Make sure that the waste saddle is installed correctly over hole in drain pipe and that there
         is no obstruction.

-    Water runs out quickly or reduced flow from faucet – Note 1.
-    Faucet drips – Note 2
-    No water at all from faucet – Note 3
-    Unit vibrates for 30 seconds erratically – Note 4
-    Monitor (if present) flashing red – Note 5
-    Monitor not working – Note 6
-    High TDS reading from faucet – Note 7
-    Water tastes metallic – Notes 7 & 8

Before attempting anything, run through mandatory check list.

Note 1 – The membrane in these units makes about 100 litres per day at 80 psi. Recovery time
should be about an hour.
Note 2 – Recondition with seal kit.
Note 3 – Check mains pressure in house –has the water been turned off?
Note 4 – In some cases this is normal – the shut-off valve is in between open and shut.
Repositioning the unit in the cupboard may help noise reduction. Replace ASOV valve if noise is
Note 5 – Replace cartridges if at 6 month period (i.e. approx. 6 months since last filter change).
Monitor (if present) will need re-setting by disconnecting from the batteries and reconnecting then
pressing the reset button (if present). If still no change – monitor is faulty –reset and /or replace
batteries, or replace monitor and batteries.
Note 6 – This is normal after a filter change or reinstallation and the milky appearance is due to
tiny air bubbles in the water – this should subside after 2 to 3 weeks.
Note 7 – Empty tank completely and recheck. If no different, backflush membrane using flushing
tool, recheck. Be careful with seal and lubricate all rubber parts. Replace membrane, reading
should be 90% or more less than tap water TDS.
Note 8 – Replace cartridges pre and post, drain tank.
Note 9 – Possible dirt in non-return valve or restriction in multi-valve. Clean strainer. If still
apparent – check non-return valve in the back of unit and replace. This is the valve coming
immediately out of the membrane housing.
Note 10 – Replace seals on caps.
