SINGlE ZONE – DUCTED TO HVAC SySTEM INSTAllATION
Using the dehumidifier in conjunction with the HVAC system is the optimum solution
for year-round, whole-home control . This installation is typically in basement or attic
locations, where air is pulled from the return duct, dehumidified, and discharged
to the supply duct . Additional configurations include only ducting the dehumidifier
outlet to the supply or ducting the inlet and outlet to the return duct . In the latter
case, the HVAC fan must be activated during dehumidification .
