The front cannot be ducted except as shown with the addition of our front intake hood.
The rear cannot be located inside the cellar, unless the cooling unit is installed with our rear duct kit, so that the fresh air comes from outside the cellar and the exhaust goes outside the cellar.
The rear can be ducted with our rear duct kit, so that the fresh air comes from outside the cellar and the exhaust goes outside the cellar.
IF THE REAR IS DUCTED, AN AUXILIARY FAN MUST ALWAYS BE USED TO
AUGMENT THE AIRFLOW OF THE HOT AIR INTAKE/EXHAUST. OUR DUCT KIT INCLUDES AN INLINE AUX FAN AND SWITCHED POWER FOR THE FAN.
