positively or negatively, depending upon the inside and outside air conditions. Consult the factory by calling 1- 800-255-7749 for recommendations regarding the use of higher flows with your specific application.

The outside air duct should be connected to the 6” round collar on the filter enclosure of the unit. The 6” round collar includes a manual damper. Adjust the manual damper to provide the desired amount of fresh air for ventilation. The amount of fresh air should be based on the size and occupancy of the residence. If you are unsure of your ventilation air requirements, consult the factory by calling 1-800-255-7749 for assistance.

2.4D Constant Airflow Regulator and Vent Hood Options

American ALDES offers the fresh air vent hood and constant airflow regulators (CAR) to control the amount of fresh air entering the home. These are used in lieu of the manual damper in the 6” collar on the main unit. The CAR, inserted in the vent hood collar, automatically maintains the desired airflow, independent of pressure. A CAR is recommended for installations where the DHV draws return air from a shared HVAC system return duct, to avoid excessive ventilation when the HVAC fan cycles on. If the indoor air return is independent of the HVAC system, the CAR is not necessary, as the manual damper may be set to the desired airflow.

2.4E Installation in a Basement or Crawl Space with an Existing Forced Air HVAC System

If the structure in which the DHV-150H is to be installed has an existing forced air HVAC system, utilize the HVAC system to make the DHV-150H installation easier.

Basement Installation: Install a separate return for the DHV-150H in a central area of the structure. Duct the supply of the DHV-150H to a 10” x 10” x 10” tee/damper that is 30% open to the basement. Duct the other side of the tee to the air supply of the existing HVAC system. Connect an insulated duct from outside to the 6” collar of the DHV-150H if you wish to provide optional fresh make-up air.

Crawl Space Installation: Install a separate return for the DHV-150H in a central area of the structure. Duct the supply of the DHV-150H to a 10” x 10” x 10” tee/damper that is 30% open to the crawl space if desired. Duct the other side of the tee to the air supply of the existing HVAC system. Connect an insulated

duct from outside to the 6” collar of the DHV-150H if you wish to provide optional fresh make-up air.

2.4F Installation in an Attic with an Existing Forced Air HVAC System

ALWAYS install a catch pan with a drain or float interrupt for condensate under the DHV-150H in an attic or condensate may drip down on the ceiling of the living space below.

Locate a separate return for the DHV-150H in a central area of the structure. Duct the supply of the DHV-150H to the air supply of the existing HVAC system. Connect an insulated duct from outside to the 6” collar of the DHV-150H if you wish to provide fresh make-up air.

2.4G Installation in a Structure with Two Forced Air HVAC Systems

Attach the DHV-150H return to an independent return from the upper level. Attach the DHV-150H supply to the supply of the basement HVAC system. This will promote circulation of air through the whole structure from the upper level to the lower level through the DHV-150H. If the DHV-150H is not connected to both areas, it will not control the humidity and ventilation of the entire structure. Connect an insulated duct from outside to the 6” collar of the DHV-150H if you wish to provide fresh make-up air.

2.4H Installation in a Structure with No Existing Forced Air HVAC System

When installing the DHV-150H in a structure that does not have a forced air HVAC system, a single return for the DHV-150H should be installed in central open area of the structure. DO NOT locate the return in a bathroom or a kitchen. The supply of the DHV-150H should be located in the remote areas of the structure (such as bedrooms, den, etc.). By ducting this way, the air inside the structure will circulate through the DHV- 150H to be filtered and dehumidified. 4" diameter duct is recommended for branches to the bedrooms, 6" diameter duct is recommended for branches to larger areas. Refer to section 2.4B for branch duct sizing. Connect an insulated duct from outside to the 6” collar of the DHV-150H if you wish to provide fresh make-up air.
