Installation Procedure - Mitsubishi Heavy Industries FDT Series Technical Manual

Request
Be sure not to install R/C at a place where temperatures around the installation surface of R/C may differ largely from
actual room temperature.
Difference between detected temperature and actual room temperature could cause troubles.
The correction for detected temperature by the R/C cannot offset such temperature difference because it corrects the
detected temperatures itself.
Request
Do not install the R/C at a place where it is exposed to direct sunlight or where surrounding air temperature exceeds 40°C
or drops below 0°C.
It could cause discoloration, deformation, malfunction or breakdown.
