1. Product characteristics and specifications

1-1 Product characteristics

 Cold and hot water stage indicator

 Front draining system

It is convenient as it can drain the cold water / room water /

hot water from the front side without moving the product when you

open the front draining door.

 Fine carbon particle reduce

At the last stage of the filtration, Plus Inno-sense filter is applied to

reduce carbon particles that sometimes come from the post carbon

filter.

 Mass gutter applying

It doesn’t need the extra secondary draining tank as it applies the

mass gutter and it is convenient as it can extract the room water

with a big vessel directly.

1-1-1 Major Part Characteristics

Part Name FEED valve / NOS valve (for safety cutoff)

Use Source water entry and safety cutoff function

Operation

principles

Opens and closes the flow path when full water signals from the low water level/full

water level sensor and overflow sensor are detected to stop entry of source water

in two ways.

Part Name Low water level / Medium water level / Full water level sensor (capacitance sensor)

Use Water level detection in the room-temperature water tank

Operation

principles

Detects the room-temperature water tank level in three stages and adjusts room-

temperature water operation through the FEED valve.

Part Name Overflow sensor (capacitance sensor)

Use Water level detection in the room-temperature water tank

Operation

principles

Operates the NOS valve to cut off room-temperature water when the water

overflow sensor detects an overflow in the room-temperature water tank.
