Important Instructions

Reverse Osmosis Process

The Reverse Osmosis process, also known as hyperfiltration, is the finest filtration process known till date. The process ensures the 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. Setts 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 as in a traditional filter.

UV Process

UV light has a shorter wavelength (higher energy) than 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 nanometers.

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 the 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 that washes away impurities from the membrane’s surface and keeps the membrane clean. !toners the following benefits:

• Lowers rejected water outflow
• Improves *TDS–rejection rates. increases the ROmembrane’sefficiency
• Extends the life of the RO membrane

UV Fail Alarm’

KENT Grand+ Mineral Roth 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 ROW 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.

In case such an alarm is audible. please call the service technician and request him to change the filters of the purifier. However. it 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 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 the LW 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 the UV chamber. After this delay. all other electrical devices such as the booster pump and solenoid valve are switched on to start the normal purification process.
Audible Alarm: The controller also controls the timing of the UV Fail Alarm and the Filter Change Alarm.

Automatic Operation

TDS Adjustment*

A unique feature in KENT Grand+ Mineral ROTM Water Purifier is the TDS control valve, which is not available in any other domestic water purifier till date. This feature allows the user to control the content of natural minerals (IDS) in purified water.
To increase the TDS level, the user can turn the screw of the valve, article wishes it will result in more mineral content in treated water. To reduce the TDS level, user can turn the screw valve clockwise, it will result in less mineral content in treated water. We recommend the TDS of the purifier to be kept at the lowest but not below 50 mg/.

Starting-up the Purifier
