Reverse Osmosis Process

The Reverse Osmosis process, also known as hyperfiltration, 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; 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 ONA 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 ONA 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 provi ding a rapid rinse which washes away impurities from the membrane’s surface and keeps the membrane clean. It offers the following benefits:

• Lowersrejected water outflow
• Improves “TDS” rejection rate. e increases the RO membrane’s efficiency
• Extends the life of the RO membrane

UV Fail Alarm*

KENT Crystal Pius 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 Crystal Plus 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 Fitter 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 fitters 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 punifier 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 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 the 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 & deansthe RO membrane on periodic intervals
• The purifier does not start if the inlet water supply pressure is below 0.3kg/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

* Tested & certified by TUV-SUD South Asia (P) Ltd.

TDS Adjustment

A unique feature in KENT Crystal Plus Mineral RO™ Water Purifier is the TOS 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 (TDS) in purified water.

To increase the TDS level, the user can turn the screw of the valve anticlockwise; it will result in more mineral content in treated water. To reduce the  TOS level, user can turn the screw valve clockwise, it will result in less mineral content in treated water. We recommend the TOS of the purifier to be kept at lowest but not

Starting-up the Purifier

• Switch on the power supply
• Waittill the storage tank fully fills up
• Switch off the power supply
• Drain the storage tank by opening the drain plug present at the bottom of the storage tank so as to remove any dust particles present in the pipes and storage tank
• Close the drain plug & switch on the power supply
• Thepurifieris ready to use

Maintenance

To ensure that the purifier operates at its optimum level, a routine maintenance must be performed. The frequency of the maintenance will greatly depend upon the raw water quality and consumption of treated water.

• Storage tank must be drained once in 2 weeks. To do so, switch off the power supply, open the drain plug at the bottom of the tank & allow the water to drain. Then screw back the plug and switch on the power supply
• Replace sediment, activated carbon & post carbon when the filter change alarm is audible or after every 12 months. It is recommended to change  the FRT when the filters are replaced
• Replace the RO membrane once in a year
• Replace the UV Lamp once in a Year
• lf you are not going to use the purifier for a long time ( in case you are on a holiday, tour, or out of home), make sure that you disconnect the  power st supply, turn off the raw water supply, and drain to the storage tank

Note: 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.
