HOW TO INSTALL REFRIGERATOR

2. How to Install Water Pipe

■Before Installation

1.The icemaker requires the water pressure of 1.5 - 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 not bend the pipe at right angle. If the length is more than 12m, there will be troubles on water supply due to water pressure drop.

4.Please install water pipe where there is no heat around.

2-1. When connecting directly to the water tap.

■Please confirm the following installation parts.
