The calorific content of the Cooling Ability column is the calorific tolerance when the internal air tempera-

ture rise within the unit is suppressed to 10 K (10 °C (50°F)) max.
Mount the heat exchanger internally as shown in Fig. 15.28 so that the internal air is drawn in from the

top and expelled through the bottom, and so that the external air is drawn in from the bottom and expelled

from the top.
