KENT TECHNOLOGY – A Breakthrough in Water Purification’

Presenting the KENT Prime Pius Mineral RO™ Water Purifier. It uses futuristic and state-of-the-art technology to provide purer and healthier drinking water.

At the heart of the KENT Prime Pius Mineral RO™ Water Purifier is a Reverse Osmosis membrane having capillanes as small as 0.0001 microns, which reduce dissolved impurities (salts and heavy metals) and convert hard water to sweet and pure drinking water. With a patented mineral retention system, the KENT Prime Pius Mineral RO™ Water Purifier allows the user to control the Total Dissolved Solids (TDS) level in the purified water.

KENT is pleased to introduce Zero Water Wastage Technology™ that reciculates rejected water to overhead tank with its own pump to make it a Zero Water Wastage RO. This unique technology helps you make water 100% pure, without wasting any water while retaining essential minerals.

Important Instructions

Avoid exposure to direct sunlight and installation in damp areas.

|

Make sure that the temperature of the water entering the purifier is within 10ºC-40ºC

---|---

The rejected water can be re-circulated to overhead tank for Zero Water Wastage.

|

The maximum distance between the water source and the purifier should not be more than 3 meters.

Avoid sharp bends in the pipe. Do not bend or block the reject water pipe.

|

Do not confine the purifier in a cabinet.

In case of not using the purifier for more than two days, kindly switch off the power supply and drain the storage tank.

|

To keep the storage tank clean, it should be drained once every 15 days.

Use genuine KENT spares for optimum performance.

|

Do not try to service the purifier on your own. Instead, call a service technician for help.

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

UV light has a shorter wavelength (higher energy) than visible light. It is called ultra-violet because it is just beyond the 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 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. Thus, they are 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 which washes away impurities from the membrane’s surface and keeps the membrane clean. ltoffers following benefits:

Lowers rejected water outflow
Improves “TOS” rejection rate i.e increases the RO membrane’s efficiency
Extends life of RO membrane

lf the interface shows ‘Replace Fitter Message’. switch off the purifier and call a service technician for help.
Low RO Flow

| Low RO flow warning sign indicates reduced capacity of RO Membrane
Although the water punfier will continue working till the membrane failure happens, il is recommended to call the KENT Customer Care and ask for Membrane Replacement

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 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 tying 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. Ouring 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 es the booster pump and solenoid vaive are switched on to slart normal purification process.

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

Paste the central drill sticker on a wall al 3.6 Feet to 4.0 Feet from the ground as per your convenience.
Ensure that the sticker is pasted straight on the wall, then drill holes as per the spece provided on the sticker
Now, insert the puff up with the help of a hammer
Screw in two 10X50 self-taping screws, 5.4 inches (138 mm) apart horizontally
Carefully hang the purtfer on the wall with the help of wall mounting slot holes provided on the backside of the purifier

Note:

If the wall is not straight or the screws are not property drilled in an even position, it will Gamage your purifier
Keep the device away from heat or direct sundight
foun ix the SS ball valve (marked no. 4) to the 1/4 inch port of the 3-way connecter (marked no. 2) shown in ure 2.
Connect the 3-way connector to the raw water supply (marked as no. 1) as shown in the figure 3.
The 3-way connecior is fitted in line with the raw water supply.
The other end of the 3-way connector can be connected to a tap (marked no.3) as shown in figure 4 or can de plugged off if not required.

Step-3

Now connect one end of the white pipe to the SS ball valve and the other end to the upper push-fit elbow fitting to the left hand side of the purifier labelied WATER IN, a3 shown in figure 1.
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 overhead tank, as shown in fig 2.

Step-4
Before connecting the power supply, it is important that you perform the following functions:

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

Step-5

Connect the power supply.
Installation is complete.

TDS Adjustment*

The unique TDS Control Sysiem enables customers to retain the contents of natural minerals (TDS) in purified water, as per their requirement.

Turning the screw of the valve anti-clockwise results in increased mineral content
Turning the screw of the vaive clockwise results in decreased mineral content

We recommend keeping the TDS at lowest but not below SOma/.

Starting Up the Purifier

Switch on the power supply
Wailttiithe storage tank completely fille up**
Switch off the power supply
Drain the storage tank by opening the drain plug present at the bottom of the storage tank, 90 as. to remove any dust particles present in the pipes and storage tank
Chose the drain plug and switch on the power supply
Thepurifieris ready to use

Maintenance

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

The storage tank must be drained once in 2 weeks. To do 80, switch off the power supply, open the drain plug at the bottom of the lank and allow the water to
drain. Then, screw back the plug and switch on the power supply
Replace the sediment, activated carbon and post carbon fitter when the fitter change alarm is audible of after every 12 months. it is recommended to change the FRT when the filters are replaced
Replace the RO membeane once every year

Note: Filters and membrane are consumabies. Their replacement time is dependent on the quality of raw water and water consumption. They are not covered under the warranty. However, if a filter chokes within six months and a membrane within a yes, it will be cleaned/repaired/replaced free of cost. Changing the filters and system inspection is available on call. The treatment capacity of the RO membrane will reduce with time due to clogging of pores of membranes.
