Presenting the Excell Mineral RO Water Purifier based on state-of-the-art KENT
Technology, for purer and healthier water.
TM

The heart of Excell Mineral RO water purifier is a Reverse Osmosis membrane having
capillaries as small as 0.0001 microns that reduces even dissolved impurities (salts and heavy
metals) as well as harmful micro-organisms (bacteria, viruses etc.) and even converts hard water
to sweet and purer drinking water. It also incorporates a UV sterilisation process to give double
TM
+
protection from harmful micro-organisms. Excell Mineral RO also allows the user to
control the Total Dissolved Solids (TDS) level of purified water.

The Reverse Osmosis process, also known as
hyper filtration, is the finest filtration process
known till date. The process ensures reduction of
particles as small as ions from a solution. Reverse
Osmosis uses a semi-permeable membrane to
reduce 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 away in a stream of waste water and thus do not get accumulated as in
a traditional filter.
UV Process
The UV light has shorter wavelength (higher energy) than the visible light. It is called
ultra-violet because it is just beyond violet light in the light spectrum. Technically,
the ultra-violet light is defined to be any wavelength of light, which is shorter than
400 nanometer.
UV rays, which penetrate into the micro-organisms, are absorbed by the DNA of the
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.

UV Fail Alarm*
To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that
performs the following functions: -
UV Stabilization Delay: To ensure that the UV lamp is pre-heated and is working at its optimum
level before it starts disinfecting water, the controller provides a two seconds delay to UV lamp
when the purifier is switched on. During this period, only the UV lamp is switched on and other
electrical devices of the purifier are switched off.
Purification Delay: To ensure that the idle water lying in the internal pipes and in the UV chamber is
disinfected before being passed into the storage tank, the system provides 5 second delay when
the purifier is switched on. During this time, the UV lamp kills all micro-organisms that may be in
the water inside UV chamber. After this delay, all other electrical devices such as booster pump and
solenoid valve are switched on to start normal purification process.
Audible Alarm: The controller also controls the timing of UV Fail Alarm and the Filter Change Alarm.

Excell Mineral RO 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 following:
Two 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.

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.

The Excell Mineral RO Water Purifier is a product of advanced technology, which ensures
safe and clean drinking water. The purifier is easy and convenient to install.
Recommended Site Preparations :
100-300 V AC, 50-60 Hz connection not more than 3m away from the point of installation of purifier
Raw water supply with ½ inch nipple not more than 3m away
Drain for rejected water not more than 3m away
Space as per dimensions of the purifier
Wall/plane surface for mounting two screws and holding the machine
The system and installation need to comply with state and local laws and regulations
Specific Instructions:
TM
+
Excell Mineral RO is an under the sink purifier. Make sure that it is only mounted on a
wall. Avoid installation on wooden and metallic
stands
For optimum performance and minimum inlet pressure
required, ensure that the raw water supply tank is at least
10 ft above the level at which the purifier is installed
It is preferable to install the purifier near a sink so that
faucet can be mounted on the sink and the inlet and reject
water lines are easily available
Installation Instructions:
Screw in the two 10x50 self taping screws on a same
horizontal level at a distance of 246 mm from each other
in the wall. This can be preferably done under the kitchen
sink.
Carefully hang the purifier on the wall with the help of wall
mounting slot holes present on the back side of the
purifier as shown in the figure 1.
Fix the SS ball valve to the ¼ inch port of the 3-way
connector.
Connect the 3-way connector to the raw water supply as
shown in the figure 2. The threaded end of the 3-way connector is fitted in line with the raw water
supply. The other end can be connected to a tap or can be plugged off if not required.
Now connect one end of the white pipe to the SS ball valve and other end to the inlet of the right
most sediment filter (labeled as No.1 in the system flow diagram) (Note: white pipe is for raw
water supply).
Similarly, connect one end of the blue pipe to the outlet of the flow restrictor tube (labeled as No.
11 in the system flow diagram) and leave the other end of the pipe in the drain. (Note: Blue pipe is
for reject water)
Make a drill of 11 mm on the top of the sink or kitchen bed where the faucet (labeled as No. 11 in the
system flow chart) can be installed conveniently as per drawing. Secure the faucet to the sink, by
tightening the brass nut washer.
Tighten the 90 degree ball valve to the tank and connect it to the outlet of the purifier as
shown in the drawing.
