Important Instrucations

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. 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 wastewater, and thus do not get accumulated as in a traditional filter.

UV Process

The ultra-violet (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, ultra-violet light is defined to be any wavelength of light, which is shorter than 400 nanometers. UV rays, which penetrate into micro-organisms, are absorbed by the DNA of pathogens, 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 a 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 surf supremo and keeps the membrane clean. It offers the following benefits.

  •  Lowers rejected water outflow
  • Improves “TDS” rejection rate i.e increases RO membrane efficiency
  • Extends life of RO membrane

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-second delay to the 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 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.

Alarm: To ensure delivery of purer water, KENT Superb Alkaline in-built microcontroller controls and senses various vital components and displays their status on the digital interface.

KENT Superb Alkaline Mineral ROTM Water Purifier is equipped with a safety feature, which displays a warning signal when and if the UV lamp fails or stops working. The purifier would stop purifying water till the UV lamp is not replaced.

If the interface shows a UV failure message, switch off the purifier and call a service technician for help.The in-built smart system will display a message, warning the user to replace the filter when less than 60 hours of filter life is left.On completion of filter life a ‘Replace Filter Message’ will be displayed on the screen, and the purifier would stop purifying water till the Filter is replaced.If the interface shows ‘Replace Filter Message’, switch off the purifier and call a service technician for help.

The system takes 2 to 3 minutes to sense the water quality.

  • If the TDS levels in the purified water is within the permissible limit, the interface would display it as ‘OK’.
  • If the TDS levels in the purified water is more than the permissible limit, a warning message will display ‘High Impurities in Water’
  • If the TDS levels in the purified water is less than the permissible limit, a warning message will display ‘No Minerals in Water’

Note: If the interface displays any warning, switch off the purifier and call a service technician for help.

The KENT Superb Alkaline Mineral ROTM’ Water Purifier will display a warning message in case there is no supply of water. The purifier will automatically shut off, till the regular water supply is not restored.In case the water supply is restored and the purifier still displays the warning sign, switch off the purifier and call a service technician for help.

Installation Procedure.

  1. Paste the central drill sticker on a wall at 3.6 Feet to 4.0 Feet from the ground as per your convenience.
  2. Ensure that the sticker is pasted straight on the wall, then drill holes as per the space provided on the sticker.
  3. Now, insert the puff up with the help of a hammer.
  4. Screw in two 10X50 self-tapping screws, 7.6 inches (192 mm) apart horizontally.
  5. Carefully hang the purifier on the wall with the help of wall-mounting slot holes provided on the backside of the purifier.


  1. If the wall is not straight or the screws are not properly drilled in an even position, it will damage your purifier.
  2. Keep the device away from heat or direct sunlight.

  1. First fix the SS ball valve (marked no. 4) to the 1/4 inch port of the 3-way connecter (marked no. 2) shown in figure 2.
  2. Connect the 3-way connector to the raw water supply (marked as no. 1) as shown in figure 3. The 3-way connector is fitted in line with the raw water supply.
  3. The other end of the 3-way connector can be connected to a tap (marked no.3) as shown in figure 4 or can be plugged off if not required.


  1. Now connect one end of the white pipe to SS the ball valve and the other end to the upper push-fit elbow fitting to the left-hand side of the purifier labeled WATER IN, as shown in figure 1.
  2. Similarly, connect one end of the white pipe to the lower elbow fitting connector in the tank labeled REJECT WATER and leave the other end in the drain, as shown in fig


Before connecting the power supply, it is important that you perform the following functions:

  1. Open the SS ball valve (handle parallel to the ball valve) to start the flow of water into the purifier, as shown in the figure.
  2. Wait for 2-3 minutes to ensure that the filters are soaked in water.
