Make sure that the rejected water pipe
is not placed at a level higher from
the system, otherwise rejected water
may flow backwards into the purifier.

Avoid exposure to direct sunlight
and installation in damp areas.

Do not confine the
purifier in a cabinet.

Avoid sharp bends in the pipe
fittings. Do not bend or block
the reject water pipe.

In case of not using the purifier for more than two
days, kindly switch off the power supply and drain
the storage tank.

The maximum distance between the
water source and the purifier should
not be more than 3 meters.

Make sure that the purifier
is connected to cold water
supply only.

Do not try to service the purifier on your own. Instead,
call service technician for help.

To keep the storage tank
clean, it should be drained
once in 15 days.

UV Fail Alarm*

To ensur e delivery of pur er and healthie r water, a mi cro-process or is insta lled in the purif ier that
perfor ms th e fol lowing functions: -

UV St abiliza tion Delay: To ensure that the UV lamp i s pre-heate d and is working at its optimu m
level before it s tarts disin fecting water, the controller provides a two seconds delay to U V lamp
when t he purifier is switch ed on. During this period, o nly the UV lamp i s switched on and othe r
electr ical device s of the purifier are switched off.

Purifi cation Delay: To ensure that the idle water lying in the internal pipe s a nd in the UV chamber is
disinf ected before be ing passed into th e storage tank, t he system provi des 5 second delay w hen
the purif ier is switched on. During this time , the UV lamp ki lls all micro-org anisms that may be in
the water inside UV chamber. After this delay, all other electrical devic es su ch a s booster pump and

Excel l Mi neral RO is an u nder the s ink purifier . Make sure that i t is only mount ed on a

wall. Avoid instal lation on wooden and m etalli c
stand s

For optimu m per formance and minim um inlet pressure
required, ensure that the raw water supply tank is at least
10 ft above the level at which the purifier is ins talled

It is preferab le to install t he purifi er near a sink so that
fauce t can be mounted on the sink and the inlet and reject
water lines are easily availa ble

Insta llati on Instructi ons:

Screw in the two 10 x50 se lf tap ing sc rews o n a same
horiz ontal leve l at a distance of 246 mm from each other
in the wall. This can be preferab ly done under the kitch en
sink.

Caref ully hang the purifier on the wall with the help of wall
mount ing s lot holes present on the back side of th e
purif ier as shown in the figur e 1.

Fix the SS ball valve to the ¼ i nch p ort of th e 3- way
conne ctor.

Conne ct the 3-wa y conne ctor to the raw wate r supply as
shown in the figu re 2. The threa ded end of the 3-way connecto r is fitted in line wit h the raw water
suppl y. The other end can be co nnected to a tap or can be plugged off if not required .

Now conn ect one end of the whit e pipe to the S S ball val ve and other end to the in let of the right
most se diment filt er (la beled as No.1 in the syste m flow diagra m) (No te: white pi pe is for raw
water suppl y).

Simil arly, conn ect one end of the blue pipe to the outlet of the flow rest rictor tube (label ed as No.
11 in the system flow diagra m) 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 k itchen bed where the fauce t (l abeled as No. 11 in t he
syste m flow chart) can be installed conv eniently as per drawing. Secu re the faucet to the sink, by
tight ening the brass nut washe r.

Tight en the 90 d egree ball valve to the tank and connect it to the o utlet of the purifie r as
shown in the drawi ng.

“Testing was performed under standard laboratory conditions, actual performance may vary”

“This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3
mg/L nitrite ( In combination measured as N), and is contingent on the proper functioning of the booster
pump included as part of this system to deliver a minimum pressure on the membrane of at least 40 psi”

“This system has been tested for the treatment of water containing pentavalent arsenic (also known as As
(V), As (+5), or arsenate) at concentrations of [0.050 mg/L or 0.30 mg/L] or less. This system reduces
pentavalent arsenic but may not remove other forms of arsenic. This system is to be used on water supplies
containing detectable free chlorine residual or on water supplies that have been demonstrated to contain
only pentavalent arsenic. Treatment with chloramines (combined chlorine) is not sufficient to ensure
complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the
performance data sheet for further information”.

Arsenic (As) is a naturally occurring contaminant found in many ground waters. It generally occurs in two
forms (valences or oxidation states): pentavalent arsenic (also known as As(V), As(+5), or arsenate) and
trivalent arsenic (also known as As(III), As(+3), or arsenite). In natural ground water, arsenic may exist as
trivalent arsenic, pentavalent arsenic, or a combination of both. Although both forms of arsenic are
potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic.
More information about arsenic and its toxicity can be found on the U.S. Environmental Protection Agency
website at http://www.epa.gov/safewater/arsenic.html.

This system is designed to remove only pentavalent arsenic. This treatment system does not provide a
feature for conversion of trivalent arsenic to pentavalent arsenic. The system may remove some trivalent
arsenic, however, it has not been evaluated for its ability to remove trivalent arsenic.

Trivalent arsenic is generally more difficult to remove from drinking water than pentavalent arsenic.
Trivalent arsenic can be converted to pentavalent arsenic in the presence of an effective oxidant such as
free chlorine. The arsenic in water containing detectable free chlorine or that has been treated with another
effective oxidant will be in the pentavalent arsenic form.4 Treatment with chloramine (combined chlorine) is
not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic.

Consumers using public water supplies can contact their utility to verify whether free chlorine treatment
chemicals are being used. Private water supplies and waters that do not have detectable free chlorine
residuals should be analyzed to determine the form(s) of arsenic present and the potential need for
oxidation of trivalent arsenic to pentavalent arsenic.

Arsenic does not generally impart color, taste, or smell to water, therefore, it can only be detected by a
chemical analytical test. Public water supplies are required to monitor treated water for total arsenic
(trivalent arsenic plus pentavalent arsenic) and the results are available to the public from the utility.
Consumers using private water sources will need to make arrangements for testing. A total arsenic test
usually costs about $15-$30 and it is recommended the test be conducted by a certified laboratory. Local
health departments or environmental protection agencies can help provide consumers with a list of certified
laboratories. Some laboratories may also be able to analyze specifically for (speciate) the form(s) of arsenic
present in a water sample if requested.

This treatment system was tested under laboratory conditions as defined in NSF/ANSI 58 Drinking Water
Treatment Units – Health Effects and was found to reduce 0.30 mg/L of pentavalent arsenic in the test water
to less than 0.010 mg/L under standard testing conditions. Actual performance of the system may vary
depending on specific water quality conditions at the consumer's installation. Following installation of this
system, the consumer should have the treated water tested for total arsenic to verify arsenic reduction is
being achieved and the system is functioning properly.

The arsenic removal component of this system must be replaced at the end of its useful life of 1-2 years. The
replacement component,

can be purchased directly from the manufacturer Kent RO Systems. Ltd.
