DUCTING TO HVAC SYSTEM – CLOSET INSTALLATIONS
The dehumidifier in these applications is typically installed under or next to the HVAC equipment.. In both types of installation, the dehumidifier inlet is not ducted and pulls from the living space through a grille or louvers in the HVAC closet door.. The Preferred Installation is to locate the dehumidifier under the HVAC equipment and supply dehumidified air through the alternate outlet on the top of the unit directly to the HVAC return.. NOTE: The dehumidifier must be wired to activate the HVAC fan during dehumidifier operation in this installation.. In the Alternate Installation the dehumidifier is located next to the HVAC equipment and ducted to the HVAC supply duct using the outlet on the top of the unit.. The supply side external static pressure of the HVAC system must not exceed 0.4”w.c. for the 1830 and 0.6”w.c. for the 1850/1850W.
CAUTION
When installing the dehumidifier as part of a combustion type furnace (gas, oil, propane, etc.) HVAC system located in a closet, duct or locate the dehumidifier inlet and outlet and seal as needed to separate the circulation air from the combustion and ventilation air. Follow all local and national building and safety codes when installing or modifying any HVAC system.
