Presenting the KENT Perk Chiller Cum Water Dispenser with in-built RO Purifier. It uses state-of-the-art
technology to provide purer & healthier drinking water. The heart of KENT Perk is a RO membrane
having capillaries as small as 0.0001 microns which reduces dissolved impurities (salts and heavy
metals) as well as harmful micro-biological impurities (bacteria, viruses etc.) and also converts hard
water to sweet and purer drinking water. It also incorporates a UF membrane which further ensures
reduction of harmful micro-organisms. KENT Perk also allows the user to control Total Dissolved Solids
(TDS) level of purified water. Along with hundred percent purified water, KENT Perk provides you access
to normal as well as cold filtered water.

purer water dispenser based on a cutting edge technology which broadly comprises of RO+UF+TDS
control systems, thus taking total care of your health and well-being. It has following features:
Perk Chiller Cum Water Dispenser with in-built RO Purifier
Reverse Osmosis, also known as hyper filtration, is one of the finest purification process known so
far. It is a technique for purifying the water where pressure is applied to force liquid through a semi-
permeable membrane as in the opposite direction of normal osmosis. This process reduces salts
from potable or brackish water. When pressure is applied, purer water gets squeezed through the
membrane from the concentrated side to the diluted side. Salts dissolved in water behave as
charged ions and are repelled by the RO membrane. The rejected impurities on the concentrated
side of the membrane are washed away by a stream of water, thus not accumulating, as they do in a
traditional filter.
Reverse Osmosis Process
• Design: KENT Perk has been aesthetically maintains the water temperature between 7-
designed to fit in the work place as well as at 17°°C. This range of temperature is ideal for

UF Process
KENT Ultra Filtration is a separation process that uses UF membrane with pore size of 0.1–0.01
micron. This UF membrane has the capacity to remove colloidal materials including bacteria, cyst
and even viruses from drinking water. Low applied pressure is therefore suf ficient to achieve high
flux rates from an Ultra Filtration membrane.
Refrigeration Process
The refrigeration cycle is a common method for transferring heat from low temperature to high
temperature. The four basic components of refrigeration cycle are:
• Compressor: The compressor serves two functions. It compresses the low-pressure, low-temperature
gas into a high pressure, high-temperature gas and it keeps the refrigerant flowing through the cycle.
• Condenser: The condenser receives hot pressurised
refrigerant gas from the compressor and cools it until
the gas changes to a liquid state. In doing so, the
condenser transfers heat from the refrigerant into the
air surrounding the condenser coils.
• Capillary Tube: The capillary tube measures the
amount of refrigerant released to the evaporator (coil
type). They appear in the refrigeration cycle just before
the evaporator (coil type). If the capillary tube is
restricted, the proper flow of refrigerant will be
disturbed and the water will not be adequately cooled.
• Evaporator (Coil Type): Refrigerant changes from
liquid to gas in the evaporator and once again the
refrigeration cycle begins.
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 also offers the following benefits:
•Lowers reject water outflow
•Improves "TDS" rejection rate i.e. increases RO membrane efficiency
•Extends life of RO membrane.

The unique TDS control system enables customers to retain natural minerals in the purified water as
per the requirement.
• To increase the TDS level (mineral contents), turn the screw of the valve anticlockwise
• To decrease the TDS level (mineral contents), turn the screw of the valve clockwise
TDS Adjustment*
* Tested & Certified by TUV-SUD South Asia (P) Ltd.
• Automatically shuts off water purification process when the storage tank is full
• Does not start water purification process when the inlet water supply pressure is below
2
0.3kg/cm
• Restarts water purification process when the water level drops below the maximum level
• Stops water purification process in the absence of electricity, thus ensuring that a user gets
only purified water
• Resumes water purification process once the electrical supply is available
• Water cooling is ceased when temperature drops to 7° C

Items in the Box
1. Unpack machine and place it on a levelled surface.
2. Fix the S.S. ball valve to the ¼ inch port of the 3-way connector
as shown in the figure.
3. Connect the 3-way connector to the raw water supply as
shown in the figure. 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.
4. Now connect one end of the first fitting to the S.S. ball valve
and other end to the lower pushfit fitting on the back side of the
dispenser labelled as water in. (Note: White pipe is for raw
water supply)
5. Similarly, connect one end of the blue pipe to the second fitting connector and leave the other
end in the drain. (Note: Blue pipe is for reject water)
6. Before connecting the power supply, it is important that you perform the following functions:
(I) Open the S.S. ball valve (handle parallel to the ball valve) to start the flow of water into the purifier.
(II) Wait for 2-3 minutes to ensure that the filters are soaked in water.
7. Insert the power cord into the socket and then turn on the switches. Do not turn on the switches
at the same time. The LED on the front panel then flashes to indicate that the system is ready to
use (each LED light is having a different switch).
8. The system and installation needs to comply with state & local laws & regulations.
Installation Instructions
Electrical Circuit Diagram KENT Perk

• Make sure that the dispenser is connected to normal water supply only
• Make sure that the reject water pipe is not placed at a level higher from the dispenser, otherwise
reject water may flow backwards into the purifier
• The maximum distance between the water source and the dispenser should not be more than 3
meters
• To keep the storage tank clean, it should be drained once in 15 days
• In case of not using the dispenser for more than two days, kindly switch off the power supply and
drain the storage tank
• Do not try to service the dispenser on your own. Instead call service technician for help
• If the supply cord is damaged, it must be replaced by the manufacture, it’s service agent or
similarly qualified person in order to avoid hazard
Caution

• Ensure to keep at least 15 cm of distance between the device & wall
• Keep the unit away from direct sunlight and rain
• Empty water tank before cleaning the device
• Unplug the machine and drain out the water by opening the tap if unused for a long period of time
• This appliance is not intended for use for persons with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the appliance
Maintenance Troubleshooting
No. Breakdown Reason
1. No water output from machine • No inlet water supply
• Power cord not plugged properly
2. Amplitude vibration and loud noise • The device has not been placed on an even surface
3. Water overflow from tank • Float valve not working
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 treatment capacity of RO membrane will reduce with time due
to clogging of pores of membranes.
“This reverse osmosis system contains a replaceable component critical to the efficiency of the purifiers.
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.”
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
