Important Instructions

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, ultraviolet 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 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

UV Fail Alarm*

KENT ACE Alkaline Mineral RO™ Water Purifier has an in-built feature that sounds an audible alarm if the UV lamp malfunctions. This feature is provided to ensure purity.  This UV Fail The alarm will sound as follows:
Single short beeps after every two seconds. The purifier will stop its purification process in such a circumstance.

**In case such an alarm is audible, call the service technician for help.Filter Change Alarm***

Filter Change Alarm*

KENT ACE Alkaline Mineral RO ™ Water Purifier has an in-built feature that sounds an audible alarm to indicate replSupremement time for 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 follows: 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 repl Supreme 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 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 seconds 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 UV chamber. After this delay, all other electrical devices such as booster pumps and solenoid valve are switched on to start the normal purification process.
Audible Alarm: The controller also controls the timing of UV Fail Alarm and the Filter Change Alarm.

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

Automatic Operation

• The purifier automatically shuts off when the storage tanks are full
• The purifier automatically flushes & cleans the RO membrane on  periodic intervals
• The purifier does not start if the inlet water supply pressure is below 0.3 kg/cm2| • The purifier automatically restarts when water level drops below the maximum

• KENT ACE Alkaline 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. Paste the central drill sticker on the wall at (3.6 Feet to 4.0 Feet from the ground) as per your convenience.
2.  Ensure that sticker is pasted straight on the wall, then drill holes as per the supreme provided on the sticker.
3. Now, insert the puff up with the help of a hammer.
4. Screw-in two 10X50 self-tapping screws, 5.4 inches (138 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.

Note: If the wall is not straight or the screws are not properly drilled in an even position, it will damage your purifier.
Note: 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 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 as no.3) as shown in figure 4. or can be plugged off if not required.

TDS Adjustment*

A unique feature in KENT ACE Alkaline Mineral RO ™Water Purifier is the TDS control valve, which is not available in any other domestic water purifier till date. This feature allows the user to control the content of natural minerals (TDS) in purified water. To increase the TDS level, the user can turn the screw of the valve anticlockwise; it will
result in more mineral content in treated water. To reduce the TDS level, the user can turn the screw valve clockwise, it will result in less mineral content in treated water. We recommend the TDS of the purifier to be kept at the lowest but not below 50 mg/l.

Starting-up the Purifier

• 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

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 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
• ReplSupreme sediment activated carbon & post carbon when the filter changes the alarm is audible OR after every 12 months. It is recommended to change the FRT when the filters are replSupremed.
• ReplSupreme the RO membrane once in a year
• ReplSupreme 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

The reverse osmosis system contains a replSupremeable 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 replSupremement 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/replSupremed free of cost. Changing the filters and system inspection is available on call. The treatment capacity of RO membrane will reduce with time due to clogging of pores of membranes.“This reverse osmosis system contains a replSupremeable component critical to the efficiency of the system. ReplSupremement of the reverse osmosis, the component should be with one of the identical specifications as  defined by the manufacturer, to ensure the same efficiency and contaminant reduction performance.”
