What is REVERSE OSMOSIS?
Osmosis is a process in which water passes through a semi-permeable membrane from a less
concentratedsolutionintoamoreconcentratedone.Innaturallyoccurringosmosisprocess,reverse
osmosis is achieved by pressurizing tohigher concentrated environment. Ifhigher concentrated
environmentispressurized,waterpassesthroughlowerconcentreatedoneSemi-permeablemembranes
used in reverse osmosis systems are in pore diameter of 8-12angstroms. Water molecules are smaller
than8-12angstromsandhaveaneutralelectriccharge.Forthisreason,watermoleculescaneasilypass
throughthemembranes.However,positivelyandnegativelychargedionsandmoleculesinthewater,
bacteria and viruses cannot pass through the membranes because they are bigger than 12 angstroms
andowtothedrainage.
Asasummary,reverseosmosisisthemostidealwatertreatmentmethodforionremovalbyadvanced
ltration.Reverseosmosismethodisoneoftherapidlyprogressingtechnologies.
Design of the reverse osmosis systemrequires various technical knowledge and experience such as
productwaterquality,rawwateranalysis,typeofmembraneetc.
Reverse osmosis practices
A. O. Smith water treatment device is designed to work with minimum water pressure. It does not require
chemical use and produces quality water. It is manufactured as a compact device that can easily be

STAGES OF CLEAN WATER PRODUCTION IN REVERSE OSMOSIS SYSTEM
Feed water pressure must be minimum 3 bar for reverse osmosis system to work. If the feed water pressure
isnotsucient,thesystemcanbereinforcedwithapump.feedwaterpassesthroughthefollowingltrations
respectively;
• 1stStage:5micronppsedimentlter.Thepre-sedimentlterretainssuspendedmaterialsandparticlesin
thewaterandprotectssuccessiveltrations,especiallythemembranelter.(1mm=1000micron).
• 2ndStage:Activatedcarbonlterremovespollutants,whichareharmfultohumanhealthandmembrane
lter,byretainingorganicsubstancesandhighamountsofcancerogenicchlorineandchlorinecompounds.
• 3rdstage:Blockcarbonlterisusedformoresensitiveparticleltrationtoretainthesuspendedmaterialsin
the water.
• 4thstage:Membranelter.Thesemi-permeablemembranewith8-12angstromporesretainsbacteria,
viruses and heavy metals in the water at 95-98% and pollutant runs to the drainage through wastewater part
of membrane.
• 5thstage:Lastcarbonlter(postcarbon).Waterrunsthroughthecarbonlteratthelaststagetoprovide
clean and extremely safe drinking water.

water faucet. Insert the plug in the socket and
turnontheballvalve(page4,partnumber9).
The wastewater should be drained throughout a
wastewater pipeline (it is proper to install to the
drain pipe of the sink).
2. Sediment Filter and Activated Carbon Filter (1st
and2ndlter)arewashedtogether.Thefoulwater
should be drained out before reaching Block
Carbon(3rdlter).Onceclearwaterisobtained,
Block Carbon (3rd Filter) is washed with the water
comingthrough1stand2ndltersandblackwater
coming through block carbon should be drained
out(4thand5th,and6thlterifavailableshould
notbefedwiththiswater).BlockCarbon(3rdlter)
is washed for 10 minutes.
3. PostCarbon(5thlter)iswashedwiththewater
comingthroughtherstthreelters[before
installationofmembrane(4thlter)]andthe
water should be drained out. Once clear water is
obtained,mineralofpHlter(6thlter),ifavailable,
is washed and this process is repeated until clear
water gets.
4. Themembrane(4thlter)isinsertedinto
membrane housing in a way that the gaskets will
be underneath (These gaskets should be placed in
by getting wet and turning rightward) and the cap
of housing is closed. The membrane is fed with
water. This water should be drained out before
reachingtank,postcarbonandminerallterif
available. Until 8 litres of water is obtained from
themembrane,thewatershouldbedrainedout
directly (It takes around 45 minutes).
5. Turnontankvalveandshutothecleanwater
faucet.Thepuriedwatershouldllinthetank
anditwilltake45minutes.Attheendof45min.,
thetankshouldbelledandthewatershouldbe
drainedonceatleastbyturningonpuriedwater
faucet.
6. Youcandrinksafeandcleanwaterattheendof
these processes.

Troubleshooting Guide
FAILURE EXPERIENCED REASON RESOLUTION METHOD
•The power source is not connected
•Low inlet water pressure or no water
•Low-pressure switch failure, cannot connect the power
source
•High-pressure switch cannot be restored
•Switch Mode Power Supply is burned out
•High-pressure pump has lost pressure
•Inlet water solenoid valve is faulty, no water can get in
(no pure water)
• A pre-lter is blocked
• Check valve is blocked (waste water, no pure water)
•The RO Membrane is plugged
• Check valve has lost pressure
•High-pressure switch failure
•System is exhibiting a loss of pressure
• Pre-lter is plugged
•RO membrane is plugged
•Inlet solenoid valve failure
• Check valve is plugged
• Post-carbon lter is plugged
•High pressure pump pressure is not enough
• Storage tank doesn’t have enough pressure
• Post-activated carbon lter is plugged
•Inlet solenoid valve failed, cannot effectively
cut off the water supply
• Check valve has lost pressure (small W.W. ow rate)
• Check the power source or the power source plug
• Check the inlet water pressure
• After connecting the inlet water, measure the
resistance, replace
• After letting off the pressure, measure the resistance,
replace
• Measure the output voltage, replace
• Replace the pre-lter
• Wash or replace the RO membrane
•Replace the inlet solenoid valve
• Replace the check valve
• Replace the post-carbon lter
•Measure the high pressure pump water pressure,
replace
•Measure the water pump pressure, replace
•Replace the solenoid valve
•Observe the pure water and waste water,
replace the pre-lter
• Replace the check valve
•Clean or replace the RO membrane
• Replace the check valve
•Replace the high pressure switch
• After checking the non return valve, check whether
there is water leakage in the pipelines
• Inate the storage bucket, empty tank pressure
should be between 0.05 and 0.07MPa
• Replace the post-activated carbon lter
•Observe the waste water, replace the inlet solenoid
valve
• Observe the waste water, replace the check valve
The machine will not
start
The high pressure pump
is working properly,
but no water is being
produced
The storage tank is full
but no pure
water is owing out
The machine is turned off
but waste water has not
stopped
After the machine is
lled with water, the
machine starts repeatedly
The pure water ow is
small or not owing

FREQUENTLYASKEDQUESTIONS
“How often should lters be replaced?”
Itdependsonproperties,qualityofwater supplyandusagefrequencyofthesystem. It isrecommendedto
replacelterseverysixmonths.Werecommendthatyoureplacepostcarbonltercartridgeonceayearand
membrane every three years.
“I have replaced the cartridges newly and the water is cloudy. Is it normal?”
Afteryouhavereplacedthelters,youshoulddrainthewaterforafewminutes.Becausecarbonltersaremade
ofnaturalmaterials,cloudyblackwatermayowforawhile(10-15minutes),Keepyourfaucetopenandturno
the tank valve. Allow the water to run out until the water is clear.
“I do not often use the system, does it change life span of lters and membrane?”
Replacementdatesoftherstthreeltersdonotchange;livingorganisms(microbes,bacteria)aresettledinthe
ltersduringltration.Therefore,rstcontactwithwaterisdeemedasbeginningofreplacementperiod.Less
usageofthesystemaectsonlyreplacementperiodofmembrane.
“Can I assemble the device and replace ltersmyself ?”
Yes,youcan.However,anyotherpractisenotperformedbyaserviceproviderwillcausethewarrantytobe
voided.Iftheserviceisprovidedbyanauthorisedpersonnel,thedevicewillcontinuetobeunderwarrantytillthe
expiration date of warranty.
