In any season, excess humidity in your home can make for an uncomfortable indoor environment. Dampness, stickiness and odors are just a few of the many symptoms associated with air that has too much moisture. Honeywell has a solution with the DH90 Whole-house Dehumidifier. Unlike portable, single-room units, a Whole-house Dehumidifier is installed in your homes central heating and cooling system, and works to eliminate excess moisture in all rooms throughout your home. Plus, Honeywell DH90 Dehumidifier features an integrated ventilation control that introduces fresh, filtered air into your home as stale, moist air is being removed.

The DH90 removes a large amount of moisture from the air and the device must be connected to a drain line that will carry away the excess water. A trap in the drain line is recommended and may be required by some local codes.
The drain line should be connected to the 3/4" male pipe thread adaptor on the front of the DH90. Care should be taken to install the drain line with a continuous slope of 1" per 10' to assure proper water removal.
