Important Instructions

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 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 waste 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 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.

UV LED Failure alarm

KENT Grand Mineral RO Water Purifier has an in-built feature that sounds an audible alarm if the UV LED malfunction. This feature is provided to ensure purity. This UV LED Fail Alarm will sound as following:
Two short beeps after every three seconds.

In case such an alarm is audible, kindly switch off the purifier and call the service technician for help.

Automatic Operation

• The purifier automatically shuts off when the storage tank is full
• The purifier does not start when inlet water supply pressure falls below 0.3 kg/cm²
• 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

Installation Instructions

The KENT KENT Grand Mineral RO Water Purifier is a product of advanced technology which ensures safe and clean drinking water. The purifier is easy and convenient to install.

Recommended Site Preparations:

• Single Phase 230 V AC, 50 Hz. connection not more than 3m away from the point of installation of purifier
• Raw water supply with ½ inch nipple not more than 3m away
• Drain for rejected water not more than 3m away
• Space as per dimensions of the purifier
• Wall/plane surf Grand for mounting two screws and holding the machine
• The system and installation must comply with state and local laws and regulations

Specific Instructions:

• KENT Grand Mineral RO Water Purifier is a wall mountable purifier. Make sure that it is only mounted on a wall. Avoid installation on wooden and metallic stands
• For optimum performance and minimum inlet pressure required, ensure that the raw water supply tank is at least 10 ft above the level at which the purifier is installed
• It is preferable to install the purifier near a sink so that inlet and reject water lines are easily available

Installation Procedure:

1. 1. Paste the central drill sticker on 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 sticker.
   3. Now, insert the puff up with the help of a hammer.
   4. Screw in two 10X50 self-taping screws, 5.11 inches (130 mm) apart horizontally.
   5. Carefully hang the purifier on the wall with the help of wall-mounting slot holes provided on the back side of the purifier.

Note:

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.

2. 1. First fix the SS ball valve (marked as no. 4) to the 1/4 inch port of the 3-way connecter (marked as no. 2) as shown in figure 2.
   2. Connect the 3-way connector to the raw water supply (marked as no. 1) as shown in the figure 3. The 3-way connector is fit in line with the raw water supply.
   3. The other end of the 3-way connector can be connected to a tap (marked as no.3) as shown in figure 4 or can be plugged off if not required.
3. 1. Now connect one end of the white pipe to SS ball valve and another end to the upper push-fit elbow fitting to the left hand side of the purifier labelled as WATER IN, as shown in fig 1.
   2. Similarly, connect one end of the white pipe to the lower elbow fitting connector in tank labelled as REJECT WATER and leave the other end in the drain, as shown in fig 2.
4. 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.
5. 1. Connect the power supply.
   2. Installation is complete.

TDS Adjustment

A unique TDS Control System enables customers to retain the contents of naturals 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 valve clockwise results in decreased mineral content

• TDS Meter Calibration certificate frequency is yearly.

1. Firstly, remove the protective cap from the TDS
2. Clean the cap and fill it the water. Turn on the TDS meter and dip the head of the TDS meter to test TDS level of water. Alternatively, you can also do the same procedure in the clean container to test the TDS of the water
3. Carefully immerse the meter into the water or solution up to the maximum immersion level, which is 2 inches. Allow the display to stabilize; this takes 10 to 30 seconds. The TDS meter will automatically compensate for any temperature variations once the reading has stabilized. Now, press the hold button to save the stabilized reading.
4. After using the meter, ensure to shake off any meter. Excess water or gently wipe it with a tissue to keep it clean and dry.

Starting the Unit

• Switch on the power supply
• Wait till 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
• The purifier is ready to use

** Tested or certified flushing time - 24hrs.

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
• If 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 supply, turn off the raw water supply and drain the storage tank
• Cleaning and disinfection of the storage tank by halogenated solution (usually Chlorine) or any other equivalent disinfecting method in every three months.

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.

Replacement of spare parts are as under:

Note: Filters and membranes are consumables. Their replacement time depends upon 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 year, it will be cleaned/repaired/replaced free of cost. Changing the filters and system inspection is available on call. The treatment capacity of RO membrane will reduce time due to clogging of pores of membranes.
*This reverse osmosis system contains a replaceable component critical to the efficiency of the system. Replacement of the reverse osmosis component should be with one of identical specifications as defined by the manufacturer, to ensure the same efficiency and contaminant reduction performance.*
