IMPORTANT INSTRUCTIONS
Reverse Osmosis Process
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
rejected water and thus do not get accumulated 
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 of 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.
Note:The purified water stored in tank is disinfected using UV LED, which
automatically switches on for 30 minutes in a two hour cycle.
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 the
following benefits:
- Lowers rejected water outflow
- Improves “TDS” rejection rate i.e increases the RO membrane’s efficiency
- Extends the life of the RO membrane

Electrical Circuit Diagram
KENT Grand+ Mineral RO™ 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. The purifier will stop its
purification process in such a circumstance. 
**Filter Change Alarm***
KENT Grand+ Mineral RO™ 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.
**Computer Controlled Operation***
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.
Automatic Operation
- The purifier automatically shuts off when the storage tanks are full
- The purifier automatically flushes & cleans the RO membrane on periodic intervals
- The purifier does not start if the inlet water supply pressure is below 0.3 kg/cm’
- The purifier automatically restarts when water level drops below the maximum
- The purifier does not allow any water rejection in absence of electricity /when tank is full
Installation Instructions
The KENT Grand+ 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:
- Single Phase 100-250 V AC, 50-60 Hz. connection not more than 3m away from the point of installation of purifier
- Raw water supply with½ inch nipple 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 must comply with state and local laws and regulations
Specific Instructions:
- KENT Grand+ Mineral RO™ Water Purifier is a wall mountable 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
- Paste the central drill sticker on wall at (3.6 Feet to 4.0 Feet from the ground) as per your convenience.
- Ensure that sticker is pasted straight on the wall, then drill holes as per the space provided on sticker.
- Now, insert the puff up with the help of a hammer.
- Screw in two 10X50 self-taping screws, 5.4 inches (138 mm) apart horizontally.
- Carefully hang the purifier on the wall with the help of wall-mounting slot holes provided on the back side 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.
- 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.
- 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 fitted in line with the raw water supply.
- The other end of the 3-way connector can be connected to a tap (marked as no.3) as shown in figure 4. or can be plugged off if not required.
