• Check voltage rate.
• Check if cold water switch at the back of the unit is on.

• Unplug the power cord. When the water is supplied again,
use the unit again.
• If there is a bending in connecting hose, straighten the part.

hot & cold water temperature become abnormal. Do not
take water from the unit for 5~6 mins, then you can take
normal hot & cold water.

water flowing. The sound comes from refrigerant flowing,
so it is not a problem.
• Replace filter.

of filtered water is produced.
• Close the water supply valve and contact customer service
center.
• Clean the cold water tank. (Please refer to the cleaning
cycle on p20.)
• Replace all the filters and clean the cold water tank.
