Recommended HVAC System Installation – Attic

The recommended installation for the Ultra Series Dehumidifier in an attic involves drawing air from a central location through a dedicated return to the dehumidifier.
The supply of the dehumidifier is then ducted to the air supply of the HVAC system.
Additionally, you can utilize the optional outdoor air ventilation duct to provide outdoor air.

Components:

Installation in a Basement or Crawlspace

To install the Ultra Series Dehumidifier in a basement or crawlspace, follow these steps:

Install a separate 8-inch return for the Ultra120V in a central area of the structure.
Duct the supply of the dehumidifier to the air supply of the HVAC system using a backdraft damper.
Optional: Duct the supply of the Ultra120V to an 8 x 8 x 8 tee/damper with a gravity draft damper, adjusted to 20% open to the basement.
- Note that air takes the path of least resistance, so if the upper levels of the living space are not receiving the appropriate amount of dry air, this damper may need to be adjusted.
CAUTION: When the dehumidifier is not running, there is a chance that air from the basement or crawlspace will make its way back through the gravity damper and into the living space.

Frequently Asked Questions (FAQ)

Q: Can I install the Ultra Series Dehumidifier in any location other than an attic, basement, or crawlspace?

A: No, it is recommended to install the Ultra Series Dehumidifier only in attics, basements, or crawlspaces as specified in the user manual.

Q: What is the purpose of the optional outdoor air ventilation duct?

A: The optional outdoor air ventilation duct allows the dehumidifier to draw in fresh outdoor air, improving air quality and ventilation.

Q: How should I adjust the gravity draft damper in the basement installation?

A: The gravity draft damper should be adjusted to 20% open to the basement.
However, if the upper levels of the living space are not receiving enough dry air, you may need to adjust the damper accordingly.

a. Attic

The recommended installation draws air from a central location through a dedicated return to the dehumidifier and ducts the supply of the dehumidifier to the air supply of the HVAC system.
Utilize the optional outdoor air ventilation duct to provide outdoor air.
Install a dedicated 10″ air return for the Santa Fe Ultra120V from a central area of the structure.
Duct the supply of the Santa Fe Ultra120V to the supply of the HVAC system with a backdraft damper.
If the existing system has multiple returns, instead of installing a dedicated return to the Santa Fe Ultra120V, it is possible to select one to disconnect from the existing HVAC system and use it for the dedicated Santa Fe Ultra120V 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 the return in a bathroom or kitchen.
Control should be located remotely from the dehumidifier and placed in a central location.
