DUCTING TO HVAC SYSTEMS
No Existing Ductwork Installation
When installing the Ultra-Aire 100V in a structure that does not have a forced air HVAC system, a single
return for the Ultra Aire 100V should be installed in a central location.
Install an insulated duct from outside to the 6" collar of the Ultra-Aire 100V to provide fresh air
ventilation (optional).
The supply of the Ultra-Aire 100V should be ducted to remote areas of the structure such as bedrooms, living
room, den, etc. Be sure to utilize multiple rooms to allow air inside the structure to properly circulate. Proper
air distribution is important to ensure even humidity control and heat distribution throughout the structure.
A 6" diameter duct is recommended for branches to bedrooms. An 8" diameter duct is recommended for
branches to larger areas.
• DO NOT locate the return in a bathroom or kitchen.
• DO NOT locate the supply in rooms where doors may be closed.
• Control should be located remotely from the dehumidifier and placed in a central location.
