Important Instructions
Reverse Osmosis Process
The Reverse Osmosis process, also known as hyperfiltration, is the finest filtration process known till date. The process ensures a reduction in 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, the 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 do not get accumulated as in a traditional filter.
UV Process
The 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 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.
Auto-flushing System
Microwaves Radio
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.

UV Fail Alarm
KENT Pear1 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
purer water. This UV Fail Alarm will sound as following: One short beep after
every two seconds.
Incase 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 Pearl 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 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.
Computer Controlled Operation
To ensure delivery of purer and healthier water, a microprocessor 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 a 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 tank is full.
- The purifier automatically restarts when the water level drops below the maximum.
- The purifier automatically flushes & cleans the RO membrane on periodic intervals
- The purifier does not allow any water rejection in absence of electricity/when tank is full.
- The purifier does not start when inlet water supply pressure falls below 0.3 kg/cm’
