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 Fail Alarm*

KENT Excell+ Mineral RO™ Water Purifier has an in-built feature of an audible alarm if the UV lamp malfunctions.
This feature is provided to ensure purity. The UV Fail Alarm will sound as following:
One short beep after every two seconds.

In case such an alarm is audible, kindly switch off the purifier and call the service technician for help.
The purifier will stop its purification process in such a circumstance.

Filter Change Alarm

KENT Excell+ Mineral RO™ Water Purifier has an in-built feature of an audible alarm to indicate replacement time 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 following:
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 Stabilisation 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 storagetank,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 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 or when tank is full

• Tested & Certified by TUV-SUD South Asia (P) Ltd.

Installation Instructions

The KENT Excell+ 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 100-250V AC, 50-60 Hz. connection not more than 3m away from the point of installation of purifier
• Raw water supply with½ 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 surface for mounting two screws and holding the machine
• The system and installation needs to comply with state and local laws and regulations

Specific Instructions

• KENT Excell+ Mineral RO TM Water Purifier is an under-the-counter RO water 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 faucet can be mounted on the sink and the inlet and reject water lines are easily available

Installation Instructions

• Screw in the two 1 0x50 self taping screws at the same horizontal level at a distance of 246 mm from each other in the wall.This can be preferably done under the kitchen sink

• Carefully hang the purifier on the wall with the help of wall mounting slot holes present on the back side of the purifier, as shown in the figure 1
  

• Fix the SS ball valve to the¼ inch port of the 3-way connector

• Connect the 3-way connector to the raw water supply as shown in the figure 2. The threaded end of the 3-way connector is fitted in line with the raw water supply.The other end can be connected to a tap or can be plugged off if not required

• Now connect one end of the white pipe to the SS ball valve and other end to the inlet of the right most sediment filter (labeled as No.1 in the system flow diagram) (Note:white pipe is for raw water supply)

• Similarly, connect one end of the blue pipe to the outlet of the flow restrictor tube (labeled as No. 11 in the system flow diagram) and leave the other end of the pipe in the drain. (Note: Blue pipe is for reject water)

• Make a drill of 11 mm on the top of the sink or kitchen bed where the faucet (labeled as No. 16 in the system flow chart) can be installed conveniently as per drawing. Secure the faucet to the sink, by tightening the brass nut washer

• Tighten the 90 degree ball valve to the tank and connect it to the outlet of the purifier as shown in the drawing
  

TDS Adjustment*

The unique TDS Controller enables customers to retain the contents of natural minerals in purified water as per their requirement.

• Turning the screw of the valve anticlockwise results in an increased mineral content
• Turning the screw of the valve clockwise results in a decreased miner

Starting-up the Purifier

• Switch on the power supply
• Wait approximately for half an hour so that the storage tank fully fills up**
• Switch off the power supply
• Drain off the storage tank by opening the faucet to remove any dust particles from the pipe and storage tank
• Close the faucet & switch on the power supply
• The purifier is ready to use

Recommended Usage of Rejected Water

Although the rejected water has high concentrationof salts, it is absolutely clean and free of impurities like chlorine,dirt,sand, etc. which are present in raw water. This rejected water usually goes down the drain but if required , can be used for gardening purposes. It has high concentration of salts and minerals which accelerates plant growth. Rejected water can also be used for cleaning purposes, i.e. cleaning utensils, mopping, etc.

• Tested & Certified by TUV-SUD South Asia (P) Ltd.
  ** 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 purified water.

• Replace sediment, activated carbon block and UF filter when the filter change alarm is audible OR after every 12 months. It is recommended to change the FRTwhen the filters are replaced
• Replace RO membrane once in a year
• Replace 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

Note: Filters and membrane are consumables. 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 year, it will be cleaned/repaired/replaced free of cost. Changing the filters and system inspection is available on call. The purification capacity of RO membrane will reduce with time due to clogging of pores of membranes.

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:-
