Ducting, 4A Installing Duct Collars | American Aldes DHV-150H

An optional condensate pump kit may be installed if a lift is required to dispose of the condensate. The cond- ensate pump kit can be ordered direct from the factory. See the optional parts list for information on the kit.

2.4 Ducting

2.4A Installing Duct Collars

The DHV-150H is equipped with 10” and 6” round inlet collars and a 10” round exhaust collar. The 10” and 6” round inlet collars are designed with tabs that fold inside the filter enclosure of the DHV-150H. The 10” round exhaust collar is attached to the DHV-150H by folding the tabs inside the end panel of the DHV-150H.

2.4B Ducting for Dehumidification

For the ideal installation, draw air from the central part of the home and return it to the isolated areas of the home like the bedrooms, den, utility room, or family room. The ductwork of the existing heating system can be used to supply air to the home. If the existing supply goes to isolated areas of the home, discharge the supply of the DHV-150H into the supply of the existing heating system. If the existing heating system incorporates a central supply, installation of a separate supply duct from the DHV-150H to each isolated area is recommended. DO NOT draw air directly from the kitchen, laundry, or isolated basement. You may draw air from a basement that is open to the home. All flexible ducting connected to the DHV-150H should be UL listed.

The inlet of the DHV-150H is the 10” diameter hole in the filter enclosure of the unit. A 10” round collar is supplied with the unit to attach to round duct. The duct may be permanently attached to the collar. A 6” round collar is provided with the unit to attach to the 6” hole in the filter enclosure. The 6” collar should be capped if fresh make-up air is not desired. If fresh make-up air is desired see section 2.4C.

The outlet of the DHV-150H is located on the end of the unit. A second 10” round collar is supplied with the unit. Cut and remove the safety grid, then bend the tabs on the collar inside the hole in the cabinet end.

A length of 10 feet or more of acoustical flex ducting on the outlet of the DHV-150H will reduce air noise from the fan. A length of flexible ducting on all DHV-150H duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure.

Ducting the DHV-150H as mentioned in sections 2.4A-

2.4G requires consideration of the following points:

Duct Sizing: For total duct lengths up to 25', use a minimum 10" diameter round or equivalent rectangular. For longer lengths, use a minimum 12" diameter or equivalent. Grills or diffusers on the duct ends must not excessively restrict airflow.

Isolated Areas: Effective dehumidification may require that ducting be branched to isolated, stagnant areas. Use 8" or larger diameter branch ducting to each of two or three areas, use 6" or larger to each of four or more areas.

Connecting to existing HVAC systems: An optional 10" check damper is available from the factory to prevent reverse flow through the DHV-150H. If the DHV-150H is ducted to the supply of a high static air handler the check damper may be placed in the DHV-150H supply duct.

2.4C Ducting for Fresh Air

Fresh air can be brought into the structure by connecting a insulated duct from outside to the 6” DHV- 150H inlet and by turning on the fan switch or activating the humidity control (on units with the humidity control panel). Activate the ventilation timer on units with the ventilating & humidity control panel to bring in fresh air. Refer to section 3.5 for programming instructions for the ventilation timer. Advantages of this form of ventilation include:

1.Outside air is filtered before entering the building.

2.Outside air will be dehumidified before entering if the DHV-150H is running in dehumidification mode.

3.Drawing air from outside and blowing inside aids in slightly pressurizing the structure. This helps prevent dirty and humid air from entering elsewhere. It also reduces the potential for carcinogenic radon gas to enter and provides make-up air for open combustion and exhaust devices like the clothes drier, fireplace, and water heater.

4.The need for an alternate ventilation device may be eliminated.

In cold climates or areas where the outdoor dew point is low at times, ventilation can be used to dehumidify the structure. This approach is often more economical than running the dehumidifier to remove excess moisture from the structure. For example, in a house that experiences condensation on the interior surface of the windows during the winter, increasing the amount of ventilation will often cure the problem.

An insulated 6" diameter duct is generally sufficient to provide up to 150 CFM of outside air. Large quantities of outside air will impact DHV-150H performance

DHV-150H specifications

The American Aldes DHV-150H is an advanced ventilation unit designed to optimize indoor air quality in residential and commercial spaces. Known for its efficiency and reliability, the DHV-150H incorporates cutting-edge technologies to ensure that both air exchange and energy conservation are maximized.

One of the standout features of the DHV-150H is its high airflow capacity. It can effectively manage ventilation requirements for spaces up to 1,500 square feet, making it an ideal solution for medium to large residences and commercial buildings. The unit boasts a robust airflow rate of 150 CFM (cubic feet per minute), enabling swift air exchange and preventing the accumulation of indoor pollutants.

Energy efficiency is a hallmark of the DHV-150H, which is equipped with an advanced heat recovery ventilator (HRV) system. This technology allows the unit to recover and transfer heat from the outgoing stale air to the incoming fresh air. As a result, the DHV-150H can significantly reduce heating costs in winter, while still maintaining a comfortable indoor environment.

In terms of construction, the DHV-150H features a durable housing made from high-quality materials that ensure longevity and resistance to corrosion.
