KENT proudly presents KENT ELEGANT LITE MINERAL ROTM - its new and advanced domestic
water purifier which provides purer & healthier drinking water.
The futuristic KENT ELEGANT LITE, developed at KENT laboratory, broadly comprises of a
state-of-the-art RO+UF+TDS Control System. The initial purification by RO membrane with
porosity as fine as 0.0001 microns reduces even 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 the purified water, thus, taking total care of your health and wellbeing.
Salient Features of KENT ELEGANT Lite Mineral RO™
Do not try to service the purifier on your
own. Instead, call a technician for help.
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 the rejected water
may flow backwards into the purifier.
Make sure that the temperature
of the water entering the purifier
is within 10 C - 40 C.
o o
Avoid exposure to direct sunlight
and installation in damp areas.
Do not confine the
purifier in a cabinet.

Electrical Circuit Diagram
The Reverse Osmosis process, also known as hyper filtration, is the finest filtration process
known till date. The process ensures the reduction of particles as small as ions from a solution.
The Reverse Osmosis process uses a semi-permeable membrane to reduce salts from
potable/brackish water. In Reverse Osmosis, water pressure is applied to the impure water inlet
resulting in the squeezing of purer water from concentrated end of the membrane towards the
diluted end. Dissolved salts present in the water in the form of charged ions get repelled by the
RO membrane and are not allowed to pass through. Similarly, bacteria and germs are also
blocked by the ultra fine pores of the RO membrane. These rejected impurities, suspended on the
concentrated end of the membrane, are then washed away as a stream of waste water, thus
preventing the membrane from clogging.
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 and
organic/inorganic polymeric molecules including bacteria and viruses. Low applied pressure is
therefore sufficient to achieve high flux rates from an Ultra Filtration membrane.

1. First fix the SS ball valve (marked as no. 4) to the 1/4 inch port of the 3-way connecter
(marked as no. 2) as shown in figure 2.
2. Connect the 3-way connector to the raw water supply (marked as no. 1) as shown in the
figure 3. The 3-way connector is fit in line with the raw water supply.
3. The other end of the 3-way connector can be connected to a tap (marked as no.3) as shown
in figure or can be plugged off if not required.
1. Now connect one end of the white pipe to SS ball valve and
another end to the upper push-fit elbow fitting to the left hand
side of the purifier labelled as WATER IN, as shown in fig 1.
2. Similarly, connect one end of the white pipe to the lower
elbow fitting connector in tank labelled as REJECT WATER
and leave the other end in the drain, as shown in fig 2.
Step-3
1. Connect the power supply.
2. Installation is complete.
Before connecting the power supply, it is important that you
perform the following functions:
1. Open the SS ball valve (Handle parallel to the ball valve)
to start the flow of water into the purifier, as shown in
the figure.
2. Wait for 2-3 minutes to ensure that the filters are soaked
in water.

KENT ELEGANT LITE Mineral ROTM is a convenient and easy-to-install wall mounting model.
Recommended Site Preparations:
• Single Phase 100 – 250 V AC, 50-60 Hz not more than 3m away from the point
of installation.
• Raw water supply with ½ inch nipple not more than 3m away.
• Drain for the reject water not more than 3m away.
• Installation space as per the dimensions of the purifier.
• Wall/plane surface for mounting screws and holding the machine. Avoid installation
on wooden and metallic stands.
• For optimum inlet pressure the source water tank should be at least 10 ft. above the
purifier installed.
• Install the purifier near a sink for easy availability of inlet and reject water lines.
• The system and installation must comply with state and local laws and regulations.
1. Paste the central drill sticker on the wall at (3.6 feet to 4.0 feet from the ground) as per your
convenience.
2. Ensure that sticker is pasted straight on the wall, then drill holes as per the space provided on
the sticker.
3. Now, insert the puff up with the help of a hammer.
4. Screw in two 10X50 self-taping screws, 5.6 inches (142 mm) apart horizontally.
5. Carefully hang the purifier on the wall with the help of the wall-mounting slot holes provided on
the back of the purifier.
Note: If the wall is not straight or the screws are not properly drilled in an even position, it will
damage your purifier.
Note: Keep the device away from heat or direct sunlight.
• The purifier automatically shuts off when the
storage tank is full
• The purifier does not start if the inlet water
supply pressure falls below 0.3 kg/cm²
• The purifier automatically restarts when the
water level drops below the maximum
• The purifier does not allow any water
rejection in absence of electricity/when
tank is full
Automatic Operation
Installation Instructions

• Turning the screw of the valve
anti-clockwise, results in increased mineral
content.
• Turning the screw of the valve clockwise,
results in decreased mineral content.
• Switch on the power supply .
• Allow the storage tank to fill to its
maximum capacity.**
• Switch off the power supply.
• Open the drain plug present at the bottom
of the storage tank and drain the tank
completely. This would remove the
residual dust particles present in different
pipes and storage tank.
• Plug back the drain plug.
• Switch on the power supply.
• The purifier is now ready to use.
• The storage tank must be drained once in 2
weeks. Open the drain plug present at the
bottom of the storage tank and drain the
tank completely. Plug back the drain plug
and switch on the power supply.
• Replace the sediment filter & activated
carbon filter once in 12 months. It is
recommended to change the FRT along
with the filters.
• Replace the RO membrane once in a year.
• Replace the UF membrane once in a year.
• In the event of not using purifier for a long
time (while going for a holiday, tour etc.),
make sure that you disconnect the power
supply, turn off the raw water supply and
drain the storage tank.
The unique TDS Control System enables customers to retain the contents of natural minerals
(TDS) in the purified water, as per their requirement.
Although the rejected water has high concentration of salts, it is absolutely clean and free from
impurities such as chlorine, dirt, sand, etc. This rejected water usually goes down the drain but
can be used for gardening purposes. The high concentration of salts and minerals accelerates
the plant growth. Rejected water can also be used for cleaning utensils, mopping etc.
“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.”
Note: The reverse osmosis system contains a replaceable treatment component critical for the
effective reduction of total dissolved solids and that product water shall be tested periodically
to verify that the system is performing properly.
To ensure that the purifier operates at its BEST, routine maintenance must be performed.
Frequency of the maintenance will greatly depend upon the raw water quality and consumption
of purified water.
