KENT GEM Mineral RO™ Non-Electric Water Purifier it uses futuristic and state-of-the-art
technologytoprovidepure&healthydrinkingwater.
KENT GEM Mineral RO™ Non-Electric Water Purifier uses the household water pressure to
reverse a natural physical process called osmosis. Water is forced through a semi-permeable
membrane having capillaries as small as 0.0001 microns, which removes dissolved impurities
presentin thewaterbutretainsessential naturalmineralswithits uniqueand patentedTDScontrol
mechanism.The clean drinking water goes to the faucet or storage tank, while the impurities are
sentto thedrain.
BeforeenteringtheROmembrane,rawwaterismadetopassthroughseries ofpre-filters.Starting
with sediment filter (which removes physical and sediment impurities from the water), raw water is
then made to pass through a carbon filter, which not only removes chlorine from the water supply,
butalsoremovesanyotherchemicalandodour.
The post-carbon filter removes any taste or odour that may remain in the water after passing
through the RO membrane. To prevent water wastage, an automatic shut-off valve closes
whenevertheROfaucetisclosedorthestoragetankisfull.
KENT GEM Mineral RO™ Non-Electric Water Purifier has been designed to provide you with
continuous supply of sparkling clear, delicious water for drinking, cooking and other uses. It not
onlymakesfoodtastier, butalso eliminatesthe needto buybottledwater,thus takinggood care of

TheReverseOsmosis process,also knownas hyperfiltration, isthefinest filtrationprocessknown
till date. The process ensures removal of particles as small as ions from a solution. Reverse
Osmosis uses a semi-permeable membrane to remove salts from potable/brackish water. In
Reverse Osmosis, water pressure applied to the concentrated side forces the process of osmosis
into reverse.Under enough pressure, treated water is‘squeezed’through the membrane from the
concentrated side to the diluted side.Salts dissolved in water as charged ions are repelled by the
RO membrane. The rejected impurities on the concentrated side of the membrane are washed
awayinastream of waste water and thus,donot get accumulated as in a traditional filter.
Stage01:
Sediment Filter: The raw water is made to pass through 'Sediment Filter', which is the best
solution to remove impurities such as sand, silt and other sediments that you may or may not be
abletoseeinthewatersupply.
Stage02:
Activated Carbon Block: The water, now free from all sediments is made to pass through
'Activated Carbon Block', which removes bad taste, odour, chemicals like chlorine, and other
impurities.
Stage03:
ReverseOsmosisMembrane:The polishedwater,freefromsediment andchemical impurities is
made to pass through RO membrane which removes dissolved solids such as calcium carbonate,
chlorides,nitrates,etc.alongwithanyorganicmatter.
Stage04:
UF Membrane: Acting as a safety mechanism, the Ultra Filtration or UF membrane removes high
molecular–weight substances, colloidal materials, organic and inorganic polymeric molecules
includingbacteria andvirusesand cystsfromwater.
Stage05:
TDS Control:Theunique andpatentedTDS control systemensuresretention ofessential natural
minerals[requiredforhealthybody]inpurified water.
Stage06:
Post Carbon: Cast out of high quality activated carbon, the filter enhances the taste of purified
water.
AutomaticShut-offValveAssembly:
To conservewater,KENT GEMMineralRO™Non-Electrichasan automaticshut-offvalve system.
When the storage tank is filled to the capacity and the RO faucet is closed, pressure closes the
shut-off valve to stop the flow to drain. After some water is drawn and when the pressure in the
systemdrops,theshut-offvalveopenstoallowwatertoflowagain.
Ultra Filtration is a separation process that uses membranes with pore size in the range of 0.1 to
0.01 micron. UF membrane removes high molecular-weight substances, colloidal materials,
organicandinorganicpolymericmoleculesincludingbacteriaandviruses.Lowapplied pressureis
sufficienttoachievehighfluxratesfromanultra-filtrationmembrane.

Installation Procedure
4. Connect one end of blue pipe to elbow fitting connector labeled as
REJECT WATER and lead the other end to drain.
1. Fasten the SS ball valve to the ¼ inch port of the 3-way connector.
2. Attach threaded end of 3-way connector to raw water supply and plug-off the
other end or connect to a tap.
3. Now connect one end of white pipe to SS ball valve and other end to
elbow fitting connector labeled as RawWater, on the back side of purifier.
Use white pipe for raw water supply

6.
Turn on the lever given on SS ball valve to initiate the water flow to the purifier.
Allow the filters to pre-soak in water for 2-3 minutes.
7. Installation is complete.
Note: • In case, you choose to place water purifier under the counter, install the faucet on the kitchen sink
or slab, connect one end of the white pipe to the faucet and the other end to the fitting connector
labeled as ‘Faucet’on the back side of the purifier
• If the water purifier is placed as ‘TableTop’, never remove the dead plug from the connector
labeled as faucet
