Safety & Care Advice
You must turn off mains water to your home before installing the reverse osmosis system.
Water2buy™ installation poli y: All installation shall be performed in a neat, professional
manner in a ordan e with generally a epted trade pra ti es. Further, all installations shall
omply with all lo al laws, odes, regulations, and ordinan es.
Read all steps, guides and rules arefully before installing and using your reverse osmosis
unit. Follow all steps exa tly to orre tly install. Reading this manual will help you get all the
benefits from your reverse osmosis unit.
Do not attempt to use this produ t to make safe drinking water from non-potable water
sour es. Do not use the unit on mi robiologi ally unsafe water, or water of unknown quality.
Che k with your lo al water department for plumbing and sanitation odes. You must respe t
their instru tions and odes while installing the unit. This guide is a suggested install method;
follow your lo al odes if they differ from the instru tions given in this manual.
The non-pumped reverse osmosis unit works on water pressures of minimum 1.7bar (25 psi)
to maximum 6 bar (90 psi). If your house water pressure is over the maximum, install a
pressure-redu ing valve in the water supply pipe to the reverse osmosis unit.
The pumped reverse osmosis unit works on water pressure of minimum 1bar (15psi) to
maximum 6 bar (90 psi). If your house water pressure is over the maximum, install a
pressure-redu ing valve in the water supply pipe to the reverse osmosis unit.
Do not install the reverse osmosis unit outside, or in extreme hot or old temperatures.
Temperatures of the water supply to the reverse osmosis unit must be between 5 and 40 .
Do not install on hot water supplies.
The reverse osmosis membrane omes in an airtight sealed bag for storage and shipment, do
not use if seal is broken.
Caution: chlorine in the water will destroy the reverse osmosis
membrane. Most cities add chlorine to the water supply to kill bacteria.
The pre-filter removes chlorine before it enters the reverse osmosis
membrane. t is important to replace the filter cartridges at least every 12
months.
Where to install your reverse osmosis unit
The reverse osmosis assembly and storage tank is designed for installations under the sink,
usually in the kit hen. The reverse osmosis assembly mounts on a wall surfa e, or an sit on
the abinet floor next to the storage tank. The reverse osmosis produ t water tap installs on
the sink, or on the ountertop next to the sink.
Tubing lengths should allow for the removal of the assembly from the hanger washers for
servi ing. If tubing lengths are shortened for neater appearan e, it may be ne essary to keep
the assembly on the hanger washers for servi e.
You an also lo ate the reverse osmosis assembly and storage tank in any remote lo ation
from the tap, observing safety guides in this manual. You do need a nearby water sour e and
drain point.

Step 4.1 Step 4.1
A: Lo ate the mains water
pipe under kit hen sink.
Make sure you have
turned off the main water
supply to your house.
B: Atta h the saddle
valve to the water mains
opper pipe, if installing
the saddle valve on plasti
pipe you must bore a 3mm
hole first or the unit may
stop working.
C: Use the plasti insert
and plasti olive on the

D: Turn the saddle valve
lo kwise to pier e hole in
pipe then open fully (turn
anti- lo kwise). If only half
opened it may leak. If it
leaks, then tighten the nut
on the saddle valve.

Perform post install system checks
Turn on the mains water.
Che k for leaks at all joints and onne tions.
Wait until the entire system is pressurised.
Leave for three hours.
Che k for leaks at all joints and onne tions again.
Turn on water tap until water stops and pressure tank is empty.
It is normal for some bla k arbon fines to appear in the water when emptying the first two tanks of water.
The first two tanks of water should not be used.
After two hours, re- he k for leaks and then the system is good to use.

Sicherheitsrichtlinien
Sie müssen Ihre Wasserleitungen s hließen, bevor Sie die Umkehrosmoseanlage einbauen.
Water2buy™-installationsri htlinie: Alle installationsarbeiten müssen in einer sauberen und
fa hgere hten art in einklang mit den allgemein anerkannten handelspraktiken ausgeführt
werden. Überdies müssen alle installationen alle lokalen gesetze, vors hriften, regelungen
und verordnungen einhalten.
Lesen sie alle s hritte, anweisungen und regeln sorgfältig dur h, bevor sie ihre
umkehrosmoseanlage installieren und verwenden. Befolgen sie alle s hritte genau, um sie
korrekt zu installieren. Diese anleitung zu lesen, wird ihnen dabei helfen, alle vorteile ihrer
umkehrosmoseanlage zu nutzen.
Versu hen sie ni ht, dieses produkt zu verwenden, um sauberes trinkwasser aus quellen von
ni ht trinkbarem wasser zu gewinnen. Verwenden sie die anlage ni ht für mikrobiologis h
bedenkli hes wasser oder wasser unbekannter qualität.
Fragen sie bei ihrem lokalen wasserwerk na h den leitungs- und sanitärvors hriften. Sie
müssen si h bei der installation der anlage an ihre anweisungen und vors hriften halten.
Diese anleitung bes hreibt eine empfohlene installationsmethode, befolgen sie ihre lokalen
vors hriften, wenn diese von den in dieser anleitung gegebenen anweisungen abwei hen.
Die umkehrosmoseanlage ohne pumpe funktioniert mit einem wasserdru k von mindestens
1,7 bar (25 psi) bis hö hstens 6 bar (90 psi). Wenn der wasserdru k in ihrem haus das
maximum übers hreitet, installieren sie ein dru kreduzierventil in der zuleitung zur
umkehrosmoseanlage.
Die umkehrosmoseanlage mit pumpe funktioniert mit einem wasserdru k von mindestens 1
bar (15 psi) bis hö hstens 6 bar (90 psi). Wenn der wasserdru k in ihrem haus das
maximum übers hreitet, installieren sie ein dru kreduzierventil in der zuleitung zur
umkehrosmoseanlage.
Installieren sie die umkehrosmoseanlage ni ht im freien oder unter extrem heißen oder kalten
temperaturverhältnissen. Die temperatur des der umkehrosmoseanlage zugeleiteten wassers
muss zwis hen 5 ° und 40 ° liegen.
Installieren sie ni ht an heißwasserleitungen .
Die umkehrosmosemembran wird in einer luftdi ht vers hlossenen hülle für lagerung und
versand geliefert.
Achtung: chlor im wasser wird die umkehrosmosemembran zerstören.
Die meisten städte fügen dem wasser chlor hinzu, um bakterien
abzutöten. Der vorfilter eliminiert das chlor, bevor es in die
umkehrosmosemembran gelangt. Es ist wichtig, die filterkartuschen
mindestens alle 12 monate auszutauschen.
Wo soll die umkehrosmoseanlage installiert werden
Die umkehrosmoseanlage und der spei hertank sind für die installation unter der spüle
konzipiert, übli herweise in der kü he. Die umkehrosmoseanlage kann an einer wandflä he
montiert werden oder auf dem s hrankboden neben dem spei hertank aufgestellt werden.
Der wasserhahn für das produkt der umkehrosmose wird auf der spüle oder auf der
arbeitsflä he neben der spüle installiert.
Bitte bea hten sie: die länge der leitungen sollte die entfernung der anlage von den
aufhängungen zwe ks wartung erlauben. Wenn die die leitungen aus optis hen gründen
gekürzt werden, kann es notwendig sein, die anlage während der wartung an den
aufhängungen zu belassen.
Sie können au h die umkehrosmoseanlage und den spei hertank an einer beliebigen stelle in
einiger entfernung vom wasserhahn anbringen, sofern sie die si herheitsri htlinien auf seite 2
bea hten. Sie benötigen eine wasserquelle und eine ablaufstelle in der nähe.
