KENT proudly presents KENT Elite Plus-New - a technologically advanced commercial water
purifier based on the patented KENT Technology. The ground-breaking KENT Technology,
developed at KENT laboratory, broadly comprises of state-of-the-art RO+UV+UF+TDS Control
System. While the initial purification by RO membrane having porosity as fine as 0.0001
microns effectively removes even dissolved impurities (hard salts, heavy metals, etc.), the
double purification by UF process ensures protection against bacteria and viruses. Moreover,
the patented TDS Control System intelligently retains essential natural minerals in purified
water, thus taking total care of your health and well-being.

Reverse Osmosis also known as Hyper Filtration,
is the finest filtration process known till date. The
process ensures removal of particles as small as
ions from a solution. Reverse Osmosis process
uses a semi-permeable membrane to reduce the
dissolved salts from potable / brackish water. In
Reverse Osmosis, water pressure is applied on the
inlet impure water resulting into the squeezing of
purer wa ter from the concentrated end of
membrane towards the diluted end. Dissolved
salts present in water as 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 RO membrane. These rejected impurities suspended on the
concentrated end of the membrane are washed away in a stream of waste water preventing the
membrane from clogging.
Reverse Osmosis Process
Waste Stream
to Drain
Auto-flushing System
The purpose of the Auto-flushing System is to help prevent scaling or fouling of the RO
membrane by providing a rapid rinse which washes away impurities from the membrane's
surface and keeps the membrane clean. It offers following benefits:
n Lowers outflow of rejected water.
n Improves TDS rejection rate i.e increases RO membranes efficiency.
n Extends life of RO membrane.
UV Process
The ultra-violet (UV) light has shorter wavelength (higher energy) than visible light. It is called ultra-
violet because it is just beyond violet light in the light spectrum. Technically, ultra-violet light is
defined to be any wavelength of light, which is shorter than 400 nanometer.
UV rays, which penetrate into micro-organisms, are absorbed by the DNA of pathogen, in the water.
The DNA is altered in such a way that the pathogen cannot reproduce itself. Thus, it is essentially
killed and cannot cause infection. This process of DNA modification is called inactivation.

Use white pipe for raw water supply.
When the water cooler’s storage tank gets filled up completely the
float in the cooler will cut off the RO purified water supply from
KENT Elite Plus -New. This will further create a water pressure. In
turn the high pressure sensor installed in the machine will cut off
the electric supply to the machine. The purification of KENT Elite
Plus-New will automatically start again as soon as the water level
drops.

the other end to lower elbow fitting connector labeled as
WATER IN, on the bottom of purifier.
6. Connect one end of blue pipe to upper elbow fitting connector labeled as REJECT
WATER and lead the other end to drain.
.
7. Connect the purified water pipe to the water cooler.
8. Turn on the lever given on SS ball valve to initiate the water flow to purifier.
9. Allow the filters to pre-soak in the water for 2-3 minutes.
10. Connect the power supply.
11. Installation is complete.
UV Fail Alarm*
KENT Elite Plus-New Water Purifier has an in-built feature that sounds an audible alarm if the UV lamp malfunctions.
This feature is provided to ensure purity. This UV Fail Alarm will sound as follows:
Single short beeps after every two seconds.
In case such an alarm is audible, kindly switch off the purifier and call the service technician for help.
The purifier will stop its purification process in such a circumstance.

Filter Change Alarm
KENT Elite Plus-New Water Purifier has an in-built feature that sounds an audible alarm to indicate
replacement time for filters. This alarm will be audible after 700 hrs of use since the last filter change (or since
the time of installation). The Filter Change Alarm will sound as follows:
4 short beeps after every two seconds; for 30 seconds. The alarm will repeat after every 2 hours of use.
In case such an alarm is audible, please call the service technician and request him to change the filters of the
purifier. However, if the filters are not changed within the next 60 hours of operation, the purifier will stop
functioning to ensure purity and hygiene. The following alarm will be audible after 60 Hrs. A continuous beep
for an infinite time.
In case, such an alarm is audible, kindly switch off the purifier and call the service technician to replace
the filters. In such a circumstance, the purifier will not function unless the filters are changed.

Recommended Usage of Rejected Water
Although the rejected water has high
concentration of salts, it is absolutely clean
and free from impurities like chlorine, dirt,
sand, etc. This rejected water usually goes
down the drain but can be used for gardening
purpose. The high concentration of salts and
minerals accelerate the plant growth.
Rejected water can also be used for cleaning
utensils, mopping etc.
Maintenance
To ensure that the purifier operates at its BEST, a routine maintenance must be performed. The
frequency of the maintenance will greatly depend upon the raw water quality and consumption
of purified water.
n Tank must be drained and cleaned once in
every 15 days
n Replace RO membranes once in a year
n Replace UF membrane once in a year
n Replace sediment filter, activated carbon
filter once in a year or earlier if they
get clogged. It is recommended to
change FRT alongwith the filters
n Replace UV Lamp once in a year
Technical Specifications
*Purification capacity tested on raw water with TDS level of 750 ppm at room temperature
For optimum performance we recommend the following frequency for replacement of
cartridges:
Sediment /Activated Carbon à Once in a year or earlier if they get clogged
RO/UF Membranes à Once in a year or earlier if they get clogged
UV Lamp à Once in a year
Recommended Frequency for Filters/Membrane Change
Important Safety Instructions
Please note that the replacement time of consumables such as filters and membranes is
dependent on the quality of raw water and the quantity of water consumed.

The unique TDS Controller enables customers to retain the contents of natural minerals in
purified water, as per their requirement:
• Tur ning the screw of the valve
anti-clockwise, results in an increased
mineral content
• Turning the screw of the valve
clockwise, results in a decreased
mineral content
TDS Adjustment
We recommend keeping the TDS at lowest possible level but not below 50mg/l.
