Perk Chille r Cum Water Dispense r with in-built RO Purifi er

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 semi­permeable 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.

UF Process

KENT Ultra Fi ltra tion is a sepa ration proc ess t hat u ses UF me mbra ne with p ore s ize of 0.1– 0.01
micr on. This UF m embr ane ha s the capa city to re move co lloi dal mate rials in clud ing bact eria , cyst
and eve n viruse s from dri nkin g water. Low a ppli ed press ure is t herefor e suffi cien t to ac hieve h igh
flux rat es from an Ult ra Filtra tion membra ne.

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-tempera ture 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 t he 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

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

• Automatic ally shuts off water purificati on process when the storage tank is full

• Does not start water purificatio n process when the inlet water supply pressure is below

• Resumes water purification process once the electrical supply is available

• Water cooling is c eased when temperatur e drops to 7° C

Items in the Box

1. Unpack machine and place it on a levell ed surface.

2. Fix the S.S. ball valve to t he ¼ i nch 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 thre aded end of the 3-way connecto r
is fitted in line with the raw water supply. The other end can be
connected to a t ap or ca n be plugged off if not required.

4. Now conn ect one end of the firs t 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: W hite pipe is fo r raw
water supply)

5. Similar ly, 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 en sure that the filters are soaked in water.

7. Inser t 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 differen t switch).

8. The system and i nstallati on 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 d ays

• In case of not using the dispenser for more than two days, kindly switch off t he power supply and
drain the storage tank

• Do not try to service the dispenser on your ow n. Ins tead call service technician for help

• If the supply cord is d amaged, it m ust be replaced by th e manufa cture, it’s ser vice a gent or
similarly qualified person in order to avoid hazard
