Carrier 37HS specifications Director Diffuser

Changeover Moduline Heating/Cooling Ð Both hot air and cold air distribution are possible with a Moduline system. The Moduline unit uses a director diffuser which, sensing the duct temperature of the supply air, directs the air towards or away from the perimeter wall. (Fig. 7.)

The Moduline location for heating and cooling requires the unit to be a speci®c distance from the outside wall in order to produce satisfactory distribution of the hot air. The recommended location is shown in Fig. 8.

HEATING COOLING

With hot air in the duct, all discharge air is directed towards the perimeter wall to offset the transmission.

With cold air in the duct, the discharge is two-way blow Ð both into the room and towards the wall.
