1-4 Precautions on services

 Before the service

1. Do not let consumers disassemble, repair, or modify the product.

- Otherwise electric shock, fire, or product damage may occur as a result.

2. To prevent the risk of electric shock, unplug the unit before checking and repairing the unit.

- Before checking or repairing the unit, make sure to discharge the electrical unit of PBA.

Otherwise, high-voltage electric shock may occur as a result.

3. When disconnecting the power cord from the electric outlet, make sure to do so by pulling the power

plug, not the power cord.

- If the power cord is damaged, electric shock or fire may occur as a result.

- Do not pull out the power plug from the electric outlet with a wet hand.

 During the service

1. During the service, check for damage, deformation, or deterioration of the power plug and the

electric outlet.

- If any abnormality is found, repair or replace the power plug or electric outlet to prevent electric

shock or fire.

2. During the service, completely remove dust or foreign materials from electrical units, wiring units,

and connections.

- It is to prevent fire caused by short circuit.

3. Check whether there is moisture on the electrical parts and power plug.

- If moisture is found, replace the parts or remove the moisture completely.

4. When replacing electrical parts, make sure to use proper parts.

- Check the model number, rated voltage, and rated current of the electrical parts.

5. During a repair, make sure that the harness wiring is fixed firmly.

- If the harness wiring is defective, in may cause abnormal noise and malfunction of the unit.

6. When disassembling and refitting the unit with its side touching the ground, perform the job on a

working cloth.

- Without the working cloth, the product may get scratches.

Coway co., Ltd

2-1-2 Characteristics of major parts

 Feed-N.O.S. valve (safety shut-off)

- Use: feed water shut-off and safety shut-off.

- Operating principle: By closing/opening the water supply when sensing the full water level signal

by the water level sensor and overflow sensor, the feed water is shut off in two

steps.

 Water level sensor

- Use: Monitors the water level in the purified water tank.

- Operating principle: By sensing the water level in the purified water tank in two steps, the water

purifying operation is controlled through the feed water supply valve.

 Overflow Sensor

- Use: Monitors the overflow in the purified water tank.

- Operating principle: When the purified water tank is full, the N.O.S. valve is adjusted to stop the

water purifying operation.

 Bi-Metal (Manual type)

- Use: Prevents overheating.

- Operating principle: When overheated, the power to the heater is automatically cut off by two metal

plates with different expansion rates.

3-2-1 Precautions on installation

 The water tank capacity of this water purification system is designed for small business and

home use. It is prohibited to install the system for large business or public use. (If the water

purification system is used beyond its capacity, water shortage and/or shortened filter life

may occur as a result.)

 Install the system on a firm, level ground.

 Installation water pressure

- CHP-06EL: The water purification system provides specified water quantity in a normal condition

with the feed water pressure of 20 psi or higher.

 Installation distance from tap water supply

- Feed water pressure below 20 psi: Install the system in a place within a range of 3M in height and

5M in distance.

- Feed water pressure 20 psi or higher: Install the system in a place within a range of 3M in height

and 25M in distance.

 Do not install the system in a place where it is subjected to direct sunlight, freezing

temperature, and/or excessive moisture.

 In the case the system is newly installed or relocated, read the User’s Manual once again

before installation.

 The product is for power rating of 220V 50Hz. Check the power rating before connecting the

power cord to the electrical outlet.

 Make sure to connect the feed water inlet hose to the cold water piping.

- In the case the feed water inlet hose is connected to warm water piping with the water temperature

of 40°C or higher, filters may be damaged.

 Right after the installation, fill up the water tank and drain the water.

Repeat it at least twice before use.

 Neo Sense filter cleaning (during installation and replacement): Clean the Neo Sense filter

for about 3 minutes.

 Fine Post Carbon Filter cleaning (during installation and replacement): Clean the Fine Post

Carbon Filter for about 3 minutes.

- During the initial installation, flush the Fine Post Carbon Filter before installation.

(Flushing the Fine Post Carbon Filter during the initial installation minimizes the inflow of fine

particles into the water tank.)

 Cleaning the Neo Sense filter and Fine Post Carbon Filter

- Remove the tubing from the bottom of the Neo Sense filter.

- Connect the Fine Post Carbon Filter to the bottom of the Neo Sense filter.

- Clean the Fine Post Carbon Filter with the water coming from the Neo Sense filter for about

1 minute. (water flow rate 3LPM)

- Separate the Fine Post Carbon Filter from the Neo Sense filter.

Connect the Fine Post Carbon Filter to the bottom of the Membrane filter.
