Planning the cabinet installation
45
Preventing the recirculation of hot air
Prevent hot air circulation outside the cabinet by leading the outcoming hot air away
from the area where the inlet air to the cabinet is taken. Possible solutions are listed
below:
• gratings that guide air flow at the air inlet and outlet
• air inlet and outlet at different sides of the cabinet
• cool air inlet in the lower part of the front door, and an extra exhaust fan on the
roof of the cabinet.
Prevent hot air circulation inside the cabinet with, for example, leak-proof air baffles
at the positions shown in the diagram below. No gaskets are usually required.
