8.5kgf/cm2. (It is acceptable if city water fills a cup of
180cc with water for 3 seconds)
2. Install booster pump where the city water pressure is
below 1.5kgf/cm2 for normal operation of water and ice
dispenser.
3. The total length of water pipe shall be less than 12m. Do Valve Feed Rubber, Packing Connector, Pipe
not bend the pipe at right angle. If the length is more
than 12m, there will be troubles on water supply due to
