Comfort-Aire WHD-130A Whole House Dehumidifier

Automatic Dehumidification

This unit automatically measures and adjusts humidity throughout the day. An automatic sampling sequence takes place every hour. To accomplish this, the unit’s fan runs for 15 minutes to sample the air in the home and to sense the of humidity level. The sample passes over a sensor that turns the compressor on if dehumidification is needed. Both the fan and compressor will then run until the humidity level of the air entering the unit reaches the preset level.

If the unit is connected to a central HVAC system—and the room thermostat calls for heating or cooling while the dehumidifier is operating—the unit will stop running until the A/C, furnace, or heat pump brings the temperature to your
desired level. After the A/C stops, the dehumidifier will begin the sampling sequence again to ensure that the home remains at a comfortable level.

Effective, Efficient Moisture Control

When the dehumidifier's fan is running, moist air from the home is drawn into the unit via the inlet duct. The air passes through the filter to remove airborne contaminants and then continues on through the cold evaporator coil. This causes the moisture to condense on the coil, much like condensation found on a glass of ice water. The moisture falls into a stainless steel drain pan and is carried away by the drain hose. The air then passes through the condensing coil, where it is warmed before being discharged back into your home. To maximize this process, a thermostatic expansion valve provides precise refrigeration control over a wide range of operating temperatures.

Simple, Flexible Installation

This Comfort-Aire dehumidifier can be used as a standalone appliance in a large or very moist basement area of 3,000 sq. ft. or less. To set up this configuration, you must have an electrician hardwire the unit into your electrical system and run a drain line. The WHD-130A whole house dehumidifier can also be installed as part of your existing HVAC system. This configuration requires that insulated, flexible ducts be used to connect the dehumidifier’s inlet to the air conditioner’s return duct. The dehumidifier outlet then connects to the air outlet of the air conditioner.

The unit can be installed in new construction or in existing structures as well as in basements, attics, or crawl spaces. Measuring in at roughly 2 sq. ft., the unit does not require a lot of room. It can sit on a flat surface using the included rubber feet for leveling. The unit can also be suspended with the optional hanger kit (Part No. WDH-14), which includes four brackets and four rubber isolators.

Other Features and Benefits

• Optional Wall-Mounted Control—The WHD-130A dehumidifier comes with self-contained controls. However, these controls are easily converted to dehumidistat controls that can be mounted in the living area (similar in appearance to a thermostat). This can save you many trips to the basement or attic to change the unit settings.
  
  
• Washable Air Filter—A permanent nylon mesh air filter captures particulates and airborne dirt to improve your indoor air quality. This filter is easily accessed from either side of the unit for cleaning.



• Frost Control—Frost can collect on the unit's coil after prolonged operation or if the home is kept at very cool temperatures. To protect against damage caused by these conditions, the unit is equipped with an automatic defrost system. This system automatically turns off the compressor if ice is present, but keeps the fan running until ice accumulation is melted. Once the coil is clear, the dehumidifier will resume normal operation.



• Minimal Maintenance—The Comfort-Aire WHD-130A is built for long-life and trouble-free operation. Periodic cleaning of the air filter keeps the unit operating at peak efficiency.



• Quiet Operation—The whole house unit is designed for quiet operation. The cabinet is lined with 1-in.-thick, high-density, expanded polyethylene insulation. This material absorbs and reflects sound, keeping unwanted noise from the duct system and living spaces. Moreover, the compressor is mounted on rubber isolators to prevent vibration, and the entire unit can be placed on rubber feet or suspended using optional rubber isolators to further reduce noise transmission into the home.



• Energy-Efficient—Because drier air is more comfortable, many people actually raise the temperature setting on their air conditioner when a dehumidifier is installed. This helps to reduce the load on your air conditioner, extend its life, and save energy dollars.



• Fits Any Size Home—With any dehumidifier, the unit’s capacity is correlated with the amount of time it takes for the home's humidity level to reach a comfortable medium. By removing 130 pints of moisture per day, the WHD-130A is effective in virtually every home and in the most humid conditions.
