NOTE
THIS INDOOR UNIT USES A DRAIN PUMP FOR
CONDENSED WATER DRAINAGE. INSTALL THE UNIT
HORIZONTALLY TO PREVENT WATER LEAKAGE OR
CONDENSATION AROUND THE AIR OUTLET.
Panel Installation
• The front panel can only be fitted in one direction, follow the piping direction. (Observe the piping arrow sticker on the
front panel).
• Be sure to remove the installation template before installing the front panel.
Drain Piping Work
• Drain pipe must be in downward gradient for smooth
drainage.
• 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 8.0mm) on the drain piping to avoid
the condensed water dripping inside the room.
Drain Test
• Connect the main drain pipe to the flexible drain hose.
• Feed water from flexible drain hose to check the piping for
leakage.
• When the test is completed, connect the flexible drain hose
to the drain connector on the indoor unit.
OPEN
SCREWS
