• Do not install in the following locations:
- Locations where sulfurous acids and other corrosive gases may
be present in the atmosphere. Copper piping and soldered joints
may corrode, causing refrigerant to leak.
- Locations where a mineral oil mist, spray or vapor may be pres-
ent in the atmosphere. Plastic parts may deteriorate and fall off or
cause water leakage.
- Locations where equipment that produces electromagnetic
waves is found. The electromagnetic waves may cause the con-
trol system to malfunction, preventing normal operation.

• When installing, take strong winds, hurricanes or earthquakes into
account, improper installation may result in the unit turning over.
4.2. Weather related precautions
• Be sure that the air inlet of the unit is not positioned towards the
main wind direction. Frontal wind will disturb the operation of the
unit. If necessary, use a screen to block the wind.
• Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in the
construction.
• When installing in areas where air contains high levels of salt such
as near the ocean; Contact your Daikin sales representative for
additional precautions.
