• Refer to the paper pattern for installation for hole positions.
• Fix the positions for suspension bolt, piping hole, drain piping hole, and electric wire hole, and make the openings.
Drain Piping Work
Rig the drain pipe as shown below and take measures against condensation. Improperly rigged piping could lead to
leaks and eventually wet furniture and belongings.
(1) Carry out the drain piping.
• For drain work, rig the pipes so that they drain reliably.
• The drain pipe outlet direction can be chosen from the right rear, right, left rear, and left. Refer to "REFRIGER-
ANT PIPING WORK" for right rear and right direction, and refer to Fig. 20 for left rear and left direction.
• For left drain pipe outlet, remove the rubber plug and the insulation on the drain pipe connecting opening on the
left side of the unit and change the position to the right side.
• Insert the rubber stopper securely, all the way to the base, in order to prevent water leakage.
• The diameter of the drain pipe should be greater than or equal to the diameter of the connecting pipe. (Vinyl tube ;
pipe size : 20 mm ; outer dimension : 26 mm)
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from form-
ing. (Refer to Fig. 21)
• Use the drain hose (1) and the metal clamp (2).
Insert the drain hose into the drain socket, up to the gray tape. (Refer to Fig. 22)
Tighten the metal clamp until the screw head is less than 4 mm from the hose. (Refer to Fig. 23)
(Be careful of the installation direction. Install so that the metal clamp does not contact the intake grill.)
• Wrap the sealing pad (8) (accessory) over the clamp and drain hose to insulate. (Refer to Fig. 23)
• No folding of drain hose inside the indoor unit. (Refer to Fig. 24)
(If there is slack in the drain hose, it may cause damage to the intake grill.)
