15.5.2 Heat Exchanger Specifications
To improve the cooling abilities of the control panel, install one of the Heat Exchangers (manufactured
by Yaskawa) shown in Table 15.8.

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.
