It uses futuristic and state-of-the-art technology to provide purer and healthier drinking water. At the heart of KENT Sapphire Mineral ROTM Water Purifier is a Reverse Osmosis membrane with capillaries as small as 0.0001 microns that reduce even dissolved impurities (salts and heavy metals) and even converts hard water to sweet and purer drinking water. The KENT Sapphire Mineral ROTM Water Purifier also allows the user to control the Total Dissolved Solids (TDS) level of purified water.

Warranty Card : 1N 1 2 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 semipermeable 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 as in a traditional filter. 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 3 3 9 Water Flow Diagram 13 14 RO Water 11 S.NO.

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. In case of UV LED failure it sounds an alarm with two beeps. In case such an alarm is audible, call the service technician for help. Filter Change Alarm* KENT Sapphire Mineral ROTM 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, 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 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 The purifier automatically flushes & cleans storage tanks are full. the RO membrane on periodic intervals The purifier does not start if the inlet water supply pressure is below 0.0344 MPa The purifier automatically restarts when water drops level below the maximum rejection in absence of electricity/when tank is full The purifier does not allow any water 5 Installation Instructions The KENT Sapphire Mineral ROTM Water Purifier is a product of advanced technology, which ensures safe and clean drinking water.
