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 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 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 the 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. 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. It offers following benefits.

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

All though the water purifier will continue working till the membrane failure happens, it 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 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 normal purification process.

Alarm: To ensure delivery of purer water, KENT ACE Star in-built micro controller controls and senses various vital components and displays their status on the digital interface.

Automatic Operation

• The purifier automatically shuts off when the storage tank is full
• The purifier does not start if the inlet water supply pressure falls below 0.3 kg/cm²
• The purifier automatically restarts when the water level drops below the maximum
• The purifier does not allow any water rejection in absence of electricity/when tank is full

Installation Instructions

Specific Instructions:

• KENT ACE Star 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 purifier
• It is preferable to install the purifier near a sink so that the inlet and reject water lines are easily available

Installation Procedure:

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

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 or can be plugged off if not required.

Step-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.

Step-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.

Step-5

1. Connect the power supply.
2. Installation is complete

Recommended Usage of Rejected Water
Although the rejected water has high concentration of salts, it is absolutely clean and free from impurities like chlorine, dirt, sand, etc. So do not flush down the rejected water as it can be used for gardening purpose.

**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 anti-clockwise results in an increased mineral content
• Turning the screw of the valve clockwise results in a decreased mineral content

We recommend keeping the TDS at the lowest possible level but not below 50mg/l.

Starting-up the Purifier

• Switch on the power supply
• Allow the storage tank to fill till the maximum level**
• Switch off the power supply
• Open the upper cover, lift and drain the storage tank to remove residual dust particles present inside the pipe and storage tank
• Place back the storage tank and close the upper cover
• Switch on the power supply
• Purifier is ready to use

The glowing Red LED indicates that the power is ON. The glowing Green LED indicates that
the purification process is ON.

Maintenance

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

• Storage tank must be cleaned once in a week (Refer Cleaning the Water Tank)

• Replace sediment filter and activated carbon filter once in 12 months or earlier if they get
  clogged. It is recommended to change the FRT along with the filters

• Replace RO membrane once in a year or earlier if it gets clogged

• Replace UF membrane once in a year or earlier if it gets clogged

• In the event of not using purifier for a long time (while going for a holiday, tour, etc.), ensure that you disconnect the power supply, turn off the raw water supply and drain out the storage tank

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 membrane 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 purification capacity of RO membranes will reduce with time due to clogging of pores of membranes.
