Recommended HVAC System Installations
DUCTING TO HVAC SYSTEMS
• Install a dedicated return for the Ultra-Aire
120V from a central area of the structure.
• Install an insulated duct from outside to the
6" damper of the Ultra-Aire 120V to provide
fresh air ventilation (optional).
• The optional second supply of the Ultra-Aire
120V may be ducted to another location. This
can provide a second source of airflow to the
basement or supply of the existing HVAC
system with a backdraft damper.
• When using only one of the two supplies on
the Ultra-Aire 120V, the unused supply must be
blocked using the duct cover plate included.
• DO NOT locate return in a bathroom or kitchen.
• Control should be located remotely from the
dehumidifier and placed in a central location.
Dedicated Ultra-Aire Return to HVAC Supply
• Locate the dehumidifier under or next to the HVAC system
as space allows. A passive vent or louver door with a
minimum net free area of 1 square foot is required to
allow air to be pulled in from the living space.
• No inlet duct is required. Air is pulled through the
passive vent or louver door from the living space.
Where outlet space is restricted, the outlet duct
collar is optional.
• Install an insulated duct from outside to the 6" collar
of the Ultra-Aire 120V to provide fresh air ventilation. If
the fresh air ventilation duct is to be used, the return of
the Ultra-Aire 120V must be ducted or an inline fan may
be required on the fresh air ventilation line to bring in
outside air.
• Duct the supply of the Ultra-Aire 120V to the supply of
the existing HVAC system with a backdraft damper.
• Control should be located remotely from the
dehumidifier and placed in a central location.
WARNING!
WHEN INSTALLING THE DEHUMIDIFIER AS PART OF A COMBUSTION TYPE HVAC SYSTEM (GAS,
OIL, PROPANE, ETC.), FOLLOW ALL LOCAL AND NATIONAL BUILDING AND SAFETY CODES.
