CAUTION
• The suggested shortest pipe length is 8.2 ft. (2.5 m), in order to avoid noise and vibration from the
outdoor unit. (Mechanical noise and vibration may occur depending on how the unit is installed and
the environment in which it is used.)
• See the installation manual of outdoor unit for information on maximum pipe length.
Step 3: Install drain pipe
• Insert supplied drain hose into drain pan socket of the indoor unit and make sure it adheres to the seat
of the socket.

• Connect drain pipe to supplied drain hose and bind
the joint with tape.
• Add insulating pipe around the indoor drain hose in
order to prevent condensation.
NOTES:
• Plastic anchors are not provided.
• The diameter of the drain pipe should be larger than or equal to that of the refrigerant pipe. (PVC pipe,
outer diameter: 1 in. (25 mm), wall thickness ≥ 1/16 in. (1.5 mm)).
• The drain pipe should be inclined downward so that water will flow smoothly without any accumu-
lation. There should be no trap as per below image.
