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.
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 baffl e board on the
air outlet side of the outdoor unit.
Units should be installed by licensed contractor accordingly to local code re-
quirement.

• 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
3
(obtainable at a store, inside diameter: 15 mm) as
shown in the fi gure for drainage.
• Make sure to provide drain piping with a downhill grade for easy drain fl ow.
Note:
Do not use the drain socket
1
in the cold region. Drain may freeze and it
makes the fan stop.
