When the piping is to be attached to a wall containing metals (tin plated) or metal
netting, use a chemically treated wooden piece 20 mm or thicker between the wall
and the piping or wrap 7 to 8 turns of insulation vinyl tape around the piping.
Units should be installed by licensed contractor accordingly to local code re-
quirement.
Note:
When operating the air conditioner in low outside temperature, be sure to fol-
low the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet side may be ex
-
posed directly to wind.
• To prevent exposure to wind, install the outdoor unit with its air inlet side facing
the wall.
• To prevent exposure to wind, it is recommended to install a baffle board on the air
outlet side of the outdoor unit.

• Provide drain piping before indoor and outdoor piping connection. (It will be hard
to install drain socket
1
if indoor and outdoor piping connection is conducted prior
to drain piping as outdoor unit becomes immovable.)
• Connect the drain hose
(obtainable at a store, inside diameter: 15 mm) as
shown in the figure for drainage.
• Make sure to provide drain piping with a downhill grade for easy drain flow.
Note:
Do not use the drain socket
1
in the cold region. Drain may freeze and it
makes the fan stop.
