3.2. Combiningindoorunitswithoutdoor
units
For combining indoor units with outdoor units, refer to the outdoor unit installa-
tion manual.
• Select a location so that air can be blown into all corners of the room.
• Avoid locations exposed to outside air.
• Selectalocationfreeofobstructionstotheairowinandoutoftheunit.
• Avoid locations exposed to stream or oil vapour.
• Avoidlocationswherecombustiblegasmayleak,settleorbegenerated.
• Avoid installation near machines emitting high-frequency waves (high-
frequency welders, etc.)
• Avoidlocationswheretheairow isdirectedata realarmsensor.(Hotair
could trigger the alarm during the heating operation.)
• Avoid places where acidic solutions are frequently handled.
• Avoid places where sulphur-based or other sprays are frequently used.
• If the unit is run for long hours when the air above the ceiling is at high tem-
perature/high humidity (due point above 26 °C [79 °F]), due condensation
may be produced in the indoor unit. When operating the units in this condi-
tion, add insulation material (10-20 mm [13/32-13/16 in]) to the entire surface
of the indoor unit to avoid due condensation.

Iftheceilinglacksstrength,itmaycausetheunittofalldown,resultingin
aninjury.
