Important Safety Information

Read all the installation precautions and instructions carefully

and completely prior to beginning use. Periodic maintenance is

required in order for this product to perform as advertised.

For your safety, the information in this manual must be followed to

minimize the risk of property damage or personal injury.

Electricity Safety

Only connect the power cord to the voltage rating that matches it on the

rating plate to avoid danger such as electric shock or fire. And be sure the electric

outlet is in an inside location to protect from moisture.

Be sure the power cord not to be bent by force and do not put a heavy object on it

to avoid any electric leakage or damage.

Do not pull the power plug from the outlet with a wet hand or get the plug wet to

avoid electric shock.

Never splash the water filtration system with water to avoid the risk of electric shock.

Keep the cord out of heavy traffic areas. To avoid fire hazard, NEVER put the cord

under rugs, near heat resisters, radiator, stoves, or heaters.

Do not use a damaged power cord or plug, and loose consent where the plug

cannot be inserted securely to avoid fire or shock hazard. If the power cord is

damaged, it must be replaced by the manufacturer or its service agent or a similarly

qualified person in order to avoid a hazard.

Remove the power plug when not using for an extended period of time. Insulation

may deteriorate, causing short circuit, fire and/or electrical shock as a result.

Periodically remove dust from the power plug with a dry cloth. Dust build-up can

cause bad insulation and a fire may occur as a result.

3

Do not use with water that is microbiologically unsafe or unknown

quality without adequate disinfection before or after the system.

Installation & Use Safety

Keep the water filtration system out of direct sunlight. The sun's heat may distort

non-metallic parts and may damage the electronics.

Do not install the water filtration system where it could freeze. Freezing damage is

not covered by the warranty.

Keep the water filtration system away from place being humid and dust rising place

to avoid electric shock and fire. Never splash the water filtration system with water to

avoid the risk of electric shock.

If the water pressure at house is over the maximum working pressure of the water

filtration system (referring to the rating plate), install a pressure reducing valve in the

water supply line to it.

Only connect the water filtration system to cold water pipe. Do not run hot water

over 104 (40 ) through it. It will defect the filters of the water filtration system .

Periodical filter replacement is prerequisite for getting clean water. In case

filters are overused, the performance of filters is deteriorated. Therefore, do not miss

the time of filter replacement.

When water is stored or the product is not in use for a long time, discharge all the

water in the storage tank before use.

Install it more than 3.9inches(10cm) away from the wall for normal operation of

heater and compressor.

Do not repair, disassemble or modify. Fire and/or electrical shock may occur as a

result. For repair, contact your dealer of purchase or A/S center of Coway.

Do not allow the foreign or unexpected material into the storage tank. The filtered

water in the storage tank may be deteriorate as a result.

Immediately plug out in the case of a smoke or smell of fire to call to A/S center of

Coway. Electric shock or fire may occur as a result.

Plug out and call to A/S center of Coway in the case of any leakage from the product.

How does Coway's Water Filtration System Filter Out

Wastes?

The osmotic membrane phenomenon has been applied to Coway water filtration

system, where a TFC membrane with pores of 0.0001 (1/1,000,000 of hair) is used

to filter water. The components of our water filtration system are as follows;

Plus-Sediment Filter

Using a step-by-step filtration method per pore, this filter effectively reduces various

foreign bodies that come from the feed water pipe such as bits of rust and also protects

the membrane. The Plus-Sediment filter vastly reduces dirt, sand, rust particles, and other

sediment.

Pre-Carbon Filter

The activated carbon filter reduces chlorine, fluoride, odor, tri-halo methane, gas additive

MTBE, and organic pollutants such as pesticides, EDB, PCB, benzene, and TCE

Reverse Osmotic Membrane Filter

The reverse osmosis filter reduces cryptosporidium, viruses, coliform, bacteria, radioactive

radon, ethylene glycol(anti-freeze), arsenic, copper, iron, lead, manganese, as well as

dissolved chemical solids such as bicarbonate, cyanide, ferrocyanide, nitrates, and

nitrites.

Post-Carbon Filter

Made using coconut, this filter reduces unpleasant smell from water and enhances water

flavor.

UV Lamp

UV lamp circulates the treated water inside the reservoir tank so that it prevents

secondary contamination inside it

Coway’s Reverse Osmosis System

Note

This 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 the reverse

osmosis component should be with one of identical specifications, as defined by the

manufacturer, to assure the same efficiency and contaminant reduction performance.

10

The disposed water shall be used for cleaning a toilet, a house, dishes, and

as water for sundry uses. However, please do not use it for potable water or

cooking water.

Estimated Time of Filter Replacement

The estimated replacement time of filter which is a consumable part is not an indication of

quality guarantee period, but it means the ideal time of filter replacement. Accordingly, the

estimated time of filter replacement may be shortened in case it is used in the area of

poor water quality or in case it is used a lot.

activated carbon to reduce odor in the water and prevent proliferation of microbe.

2 Thermistor

-Use It controls the temperature of the cold water.

- Operation Principle It controls the operation of compressor detecting the temperature of

the compressor by change of resistance that varies rapidly and predictably with temperature.

7 UV Lamp( Single body type )

- Material : Quartz glass tube and pump

-Feature: UV lamp circulates the treated water inside the reservoir tank so that it prevents

contamination inside it.

16

8 Boost Pump(CHP-01AL)

-Use: It pressurizes the feed water to the proper pressure.

- Operation Principle : It keeps proper water pressure by pressurizing the feed water,

and it helps exercise its ability of filtering a certain amount of water even in the low

pressure area.

9 Lower Pressure Switch(L.P.S)

-Use: It controls the operation of Boost Pump (On/Off)

- Operation Principle : In the case of low water pressure, it makes the pump stopped for

prevention of running idle. As the water pressure is recovered, it makes pump resume

automatically.
