Recommended Hvac System Installations - Ultra-Aire 100V Installation Instructions Manual

Recommended HVAC System Installations

Basement Installation - Dedicated Ultra-Aire Return to HVAC Supply
• Install a dedicated 8" air return for the Ultra-Aire 100V from a central area of the structure.
• Install an insulated duct from outside to the 6" collar of the Ultra-Aire 100V to provide fresh air
ventilation (optional).
• Duct the supply of the Ultra-Aire 100V to a 8" x 8" x 8" tee damper that is 20 percent open to the
basement/crawlspace. Duct the other side of the tee to the air supply of the existing HVAC system
with a backdraft damper.
• If the existing system has multiple
returns, instead of installing a
dedicated return to the Ultra-Aire
100V, it is possible to select one to
disconnect from the existing HVAC
system and use it for the dedicated
Ultra-Aire 100V return. Select a return
from a central location in the house
that is always open to the rest of the
structure. DO NOT use a return from
a room where doors are kept closed.
• DO NOT locate return in a bathroom
or kitchen.
• 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.
Closet Installation - Central Return to HVAC Supply
• Locate the dehumidifier under or next to the
HVAC system as space allows. A passive vent or
louver door 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 100V to provide fresh air
ventilation (optional).
• Duct the supply of the Ultra-Aire 100V 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.
