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.
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 also offers the following benefits:-

The Reverse Osmosis process, also known as hyper
filtration, is the finest filtration process known till date.
The process ensures reduction in particles as small as
ions from a solution. Reverse Osmosis uses a semi-
per me abl e membr ane to reduc e salts fro m
potable/brackish water. In Reverse Osmosis, water
pressure applied to the concentrated side forces the
process of osmosis into reverse. Under enough
pressure, purer 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 does not
get accumulated as in a traditional filter.

The Filter Change Alarm will sound as following:
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.

To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that
performs the following functions: -
UV Stabilisation 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.
Computer Controlled Operation*

Installation Procedure :
1. Screw in two 10x50 self taping screws, 5.4 inches (138 mm) apart horizontally.
(in case of wall mounting).
2. Wall-mount the purifier with the help of slot holes given on back side.
3. Fasten the SS ball valve to ¼ inch port of 3-way connector.
4. Attach threaded end of 3-way connector to raw water supply and plug off
the other end or connect to a tap.

KENT Pearl Mineral RO is designed to facilitate both wall mounting as well as the
counter-top usage. The purifier is easy and convenient to install.
Recommended Site Preparations:
supply not more than 3m away from the point
of installation
Raw water supply with ½ inch nipple not more than 3m away
Drain for reject water not more than 3m away
Installation space as per dimensions of the purifier
For wall mounting installation, make sure that purifier is mounted on a wall. Avoid installation on
wooden and metallic stands
For optimum inlet pressure, 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

Storage tank must be cleaned once in 2 Replace RO membrane once in a year
weeks. (Refer Cleaning the water tank) Replace UV Lamp once in a year
Replace sediment filter, activated carbon In the event of not using purifier for a long
filter & post carbon filter once in 12 months time (while going for a holiday, tour etc.),
or whenever the filter change alarm make sure that you disconnect the power
activates. It is recommended to change supply, turn off the raw water supply and
FRT along with the filters drain the storage tank
Maintenance
The replacement time of consumables such as filters and membrane is dependent on the
quality of raw water and water consumed.
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.
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.”
Cleaning the Water Tank
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.
Replacement of spare parts are as under:-
