Drain elbow and hose installation
• Fix the drain elbow 2 and packing 3 to the bottom of Indoor Unit,
as shown in below illustration.
• Use inner diameter 17 mm drain hose in the market.
• This hose must to be installed in a continuosly downward direction
and in a frost-free environment.
• Guides this hose's outlet to outdoor only.
• Do not insert this hose into sewage or drain pipe that may generate
ammonia gas, sulfuric gas, etc.

the insulation by using POLY-E FOAM with thickness 6 mm or
above.
