The futuristic KENT GEM Mineral RO WATER PURIFIER, developed at KENT laboratory
broadly comprises of state-of-the-art RO+UF+TDS Control System. The initial purification by RO
membrane having porosity as fine as .0001 microns completely removes even the dissolved
impurities (hard salts, heavy metals etc.). Double purification by UF membrane gives additional
protection from deadly harmful micro-organisms. Moreover, the patented TDS Control System
intelligently retains essential natural minerals in purified water thus, taking total care of your health
and wellbeing

Important Instructions
Always use genuine Kent spares for optimum performance Do not try to service the purifier on your own.
Instead, call service technician for help.
In case of not using the purifier for more than
two days, kindly switch off the power supply
and drain the storage tank.
Avoid sharp bends in the pipe
fittings. Do not bend or block
the reject water pipe.
Maximum distance between the water
source and the purifier should not be
more than 3 meters.
Make sure that the reject water pipe
is not placed at a level higher than
the system, otherwise reject water
may flow backwards into the purifier.
Make sure that the temperature
of water entering the purifier is
o
within 10-35 C.
Avoid exposure to direct sunlight
and installation in damp areas.
Do not confine the
purifier in a cabinet.

The Reverse Osmosis process, also known as hyper filtration, is the finest filtration process known
till date. The process ensures the 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, pure 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
away in a stream of waste water and thus not get accumulated as on a traditional filter.
Ultra Filtration is a separation process that uses membranes with pore sizes in the range of 0.1 to
0.01 micron. UF membranes remove high molecular-weight substances, colloidal materials, and
organic and inorganic polymeric molecules including bacteria and viruses. Low applied pressures
are therefore sufficient to achieve high flux rates from an Ultra Filtration membrane.

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 ‘Table Top’, never remove the dead plug from the connector

Now connect one end of white pipe to SS ball valve and other end to
elbow fitting connector labeled as Raw Water, on the back side of purifier.
Use white pipe for raw water supply
TDS Adjustment
The unique TDS Control System enables customers to retain the contents of natural
minerals (TDS) in purified water, as per their requirement.
• •To increase the TDS level, turn screw of the To decrease the TDS level, turn screw of
valve anticlockwise; resulting into increase the valve clockwise; resulting into
in mineral content decrease in mineral contents.
We recommend keeping the TDS at lowest but not below 50mg/l.

Please note that the replacement time of consumables such as filters and
membrane is dependant on the quality of raw water and the quantity
of purified water consumed.
Use genuine Kent spares for optimum performance.
The reverse osmosis system contains a replaceable treatment component critical for the effective
reduction of total dissolved solids and that product water is tested periodically to verify that the
system is performing properly.
Replacement of spare parts are as under:-
-20010 SP Inline Sediment Filter 8”
-20009 SP Inline Carbon Block Filter 8”
-20002 SP RO Membrane Welded 8” Housing
-20004 SP UF Membrane Welded 8” Housing
-20018 SP FRT 550
Note: Filters and membrane are consumables. Their replacement time is dependent on the quality of raw
water and water consumption. They are not covered under the warranty. However, if a filter chokes
within six months and a membrane within a year, it will be cleaned/ repaired/ replaced free of cost.
Changing the filters and system inspection is available on call. The treatment capacity of RO membrane
will reduce with time due to clogging of pores of membranes.
“This reverse osmosis system contains a replaceable component critical to the efficiency of the system.
Replacement of the reverse osmosis component should be with one of identical specifications as
defined by the manufacturer, to ensure the same efficiency and contaminant reduction performance.”
