• Avoid installing the drain pipe in upward gradient after
the drain connection.
• Ensure the height of drain pipe from ceiling is 700mm or
less if it is necessary to increase the height of drain pipe
to prevent water leak.
• Avoid installing the drain pipe in up and down slope to
prevent reversed water flow.
• During the drain pipe connection, be careful not to exert
extra force on the drain connector at indoor unit.
• The outside diameter of the drain connection at the
flexible drain hose is 20mm.
• Be sure to execute heat insulation (polyethylene foam
with thickness more than 8mm) on the drain piping to
avoid the condensed water dripping inside the room.
• Connect the main drain pipe to the flexible drain hose.
• Feed water from flexible drain hose to check the piping
for leakage.
