• Connect drain pipe B directly to drain piping connecting part (socket side) of
drain hose .
• Be sure to connect drain hose to the indoor unit side as shown in the illus-
tration on the right. Be sure to connect the drain hose connecting part using
adhesive of polyvinyl chloride family to prevent leakage.
• To bring up the drain exit, first arrange drain hose
and then provide 1/100 or more downward slope, as shown in the illustration
below.

• If the drain piping pass indoor, be sure to apply insulating material
polyethylene, specific gravity 0.03, thickness more than 10 mm).
Connect drain hose connecting part using adhesive of polyvinyl chloride family
before installing the hose band.
• Apply insulating material J until drain piping connecting part, as shown in the
upper right illustration.
• Drain piping should form a downward slope (1/100 or more) to the outdoor
drain exit. Do not form trap or raise the pipe.
• Do not arrange the pipe horizontally for more than 20 m. When the drain piping
is too long, use support metal to prevent the drain pipe from forming an up or
down curve. Be sure not to install a air bleeder. (Since drain lift-up mechanism
is built-in, drain may blow out.)
• Odor trap for drain outlet is not necessary.
• For grouped piping, arrange piping so that the grouped piping is about 100 mm
lower than the unit drain exit, as shown in the figure. Use about a drain pipe
(O.D. 38 mm) for grouped piping, and arrange it so that it forms about 1/100
or more downward slope.
• Do not place drain piping directly into a place where ammonia gas or sulfuric
gas is formed, such as sewage tanks or septic tanks.
