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.
