Pour water into the drain pan. Check whether the hose is well
drained.
CAUTION
• Make sure that the indoor unit is in upright position when you
pour water to check for leakage. Make sure that the water does
not overflow onto the electrical part.
• If the diameter of the connection hose is smaller than the
product's drain hose, water leakage may occur.
• Inadequate installation may cause water leakage.
• If the drain hose is routed inside the room, insulate the hose
so that dripping condensation does not damage the furniture
or floors.
• Do not box in or cover the drain hose connection.
Drain hose connection must be easily accessible and
serviceable.
