If the drain riser is installed inclined, the float switch may malfunction and cause water leakage.
• Make sure to use the drain hose (1), the elbow (10) and the sealing material (Large) (8) attached to the
indoor unit as accessories.
1. To prevent the elbow from getting damaged by the metal clamp (2) for upward and backward piping,
wrap the vinyl tape around the elbow 2 to 3 times so that the tape covers more than the width of metal
clamp (2) leaving 10 - 15 mm from the tip of the elbow (10) without wrapping as shown in Fig. 30.
10~15mm
2. Insert the drain hose (1) and the elbow (10) to the root of the drain socket. Tighten the metal clamp
(2) within the taped range of hose inserted tip with the torque 1.35
(Refer to Fig. 25, 26, 27, and 31)
Drain hose (1) (accessory)
Metal clamp (2) (accessory)
Fix the metal clamp (2) so that
the screw head faces downward.
• Do not tighten the metal clamp (2) with the torque more than the specified value.
The socket, the drain hose (1), the elbow (10) or the metal clamp (2) may be damaged.
Fix the metal clamp (2) so that the tightened part may be in the range shown by Fig. 32.
3. Wrap the vinyl tape around the end of the metal clamp (2) so that the sealing material (Large) (8) to
be used at the next process may not be damaged with the clamp end or bend the tip of the metal
clamp (2) inward as shown. (Refer to Fig. 32)
