Page 10: Installation Of The Outdoor Unit
INSTALLATION OF THE OUTDOOR UNIT As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulÀ ll the following requirements: • Install the condensing (outdoor) unit in a way such that the hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). -
Page 11: Installation Clearance
INSTALLATION CLEARANCE • Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air Á ow.
