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.
 After the service
1. After the service, check the overall assembly status and terminal connection of parts.
- If the wiring is under pressure or the connection of parts is defective, reassemble the unit.
2. Make sure that internal electrical wiring is not touching sharp parts of moving parts or electrical
equipment.

2-1-2 Characteristics of major parts
 Feed+N.O.S valve (for security shut-off)
- Use: feed water shut-off and safety shut-off
- Operating principle: When the reed level sensor and overflow sensor detect the full water level
signal, the water flow is shut off, providing feed water shut-off in two steps.
 3-Way Valve
- Use: Electronically controls the extraction of cold/hot/room temperature water in a set quantity.
- Operating principle: Cold/hot/room temperature water is extracted through a single cock according
to electrical signals of the solenoid valve.
 Bi-Metal (Manual type)
- Use: Prevents overheating.
- Operating principle: When the hot water is overheated, the power to the heater is automatically cut
off by two metal plates with different expansion rates.
 Auto daily life water controller (linkage type)
- Use: Automatically controls the quantity of daily life water of the Membrane filter according to the
feed water supply pressure.
- Operating principle: The quantity of daily life water is automatically controlled by the spring tension
according to the feed water supply pressure.
 Reed level sensor
- Use: Monitors the water level in purified water tanks.
- 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 purified water tanks.
- Operating principle: When the puriedfied water tank is full, the N.O.S. valve is adjusted to stop the
water purifying operation.

3-2 Installation method
3-2-1 Precautions on installation
 The water tank capacity of this water purification system is designed for home use.
It is prohibited to install the system for medium/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 product at least 10cm away from the wall and on a firm and level floor.
 Installation water pressure
- The feed water supply pressure should be at least 20 psi for the purification system to work
properly, providing enough purified water.
 Installation distance from tap water supply
- 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.
 This product is for AC 220V/50Hz. Make sure to check the rated voltage before connect 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.
 Cleaning the Neo Sense filter 8 inch (S) (for installation and replacement):
Clean the Neo Sense filter 8 inch (S) for about 30 seconds.
 Cleaning the Post Carbon block filter 8 inch (S) (for installation and replacement):
Clean the Post Carbon block filter 8 inch (S) for about 3 minutes.
- For initial installation, flush the Post Carbon block filter 8 inch (S) before installing it.
(Flushing the Post Carbon block filter 8 inch (S) during the initial installation minimizes the inflow of
fine particles into the water tank.)
 Cleaning the Neo Sense filter and Post Carbon block filter
- Remove the tubing from the bottom of the Neo Sense filter 8 inch (S).
- Connect the Post Carbon block filter 8 inch (S) to the bottom of the Neo Sense filter 8 inch (S).
- Clean the Post Carbon block filter 8 inch (S) with the water coming from the Neo Sense filter
8 inch (S) for about 3 minutes. (Water flow rate 300~500㎖/min)
- Separate the Post Carbon block filter 8 inch (S) from the Neo Sense filter 8 inch (S) and then
connect it to the bottom of the Membrane filter (RO) 8 inch.
