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 require-
ment.
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.

Check the following parts before installation.

Drain socket (for VA type only)
Drain cap 33 (for SUZ-KA50/KA60/KA71 only)
• Provide drain piping before indoor and outdoor piping connection. (It will be hard to
install drain socket 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 in the cold region. Drain may freeze and it makes
the fan stop.
