• 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 forming. (Refer to Fig. 21)
• Use the attached drain hose (1) and clamp (2).
Insert the drain hose into the drain socket, up to the gray tape.(Refer to Fig. 22)
Tighten the 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 clamp metal does not contact the intake grill.)
• Wrap the attached sealing pad (8) 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.)
