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
(mm)
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.
4.1. Accessories
Check the following parts before installation.
<Outdoor unit>
1
Drain socket (for VA type only)
3
Drain cap ø33 (for SUZ-KA50/KA60/KA71 only)
• 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 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.
