Recommended Hvac System Installations - Ultra-Aire XT205H Installation Instructions Manual

Recommended HVAC System Installation
The recommended installation draws air from a dedicated indoor air return and ducts the supply of the
dehumidifier to the air supply of the existing HVAC system. Utilize the optional fresh air ventilation duct to
provide outside air.
• Install a dedicated 10" air return for the Ultra-Aire XT205H from a central area of the structure.
• Install an insulated duct from outside to the 6" collar of the Ultra-Aire XT205H to provide fresh air
ventilation (optional).
• Duct the supply of the Ultra-Aire XT205H to the 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 XT205H,
it is possible to select one to disconnect from the existing HVAC system and use it for the dedicated
Ultra-Aire XT205H 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.
