• Drain pipe must be downward gradient for smooth drainage.
• Avoid the drain pipe from up and down slope to prevent reversal
flow.
• During the drain piping 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 provide heat insulation (polyethylene foam with
thickness more than 8.0mm) 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 and check the piping for
leakage.
• When the test is completed, connect the flexible drain hose to
the drain connector on the indoor unit.
