PAGE 10
DUCTING TO HVAC SYSTEM – BASEMENT AND ATTIC INSTALLATIONS The Preferred Installation is to duct the dehumidifier to pull air from and return dehumidified air to the HVAC return duct. This installation will ensure warm, dehumidified air is thoroughly mixed with the HVAC system air before being discharged into the living space. Alternatively, the dehumidifier can be ducted to discharge to the supply duct, but the external static pressure of the HVAC system must not exceed 0.4"w.c. for the E080 and 0.6"w.c.
PAGE 11
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.
PAGE 12
DUCTING FOR TWO ZONE INSTALLATIONS Note: Dehumidifier zoning is not recommended in HVAC zoning applications. FIGURE 20 – WHOLE-HOME PRIMARY ZONE INSTALLATION In this installation the dehumidifier controls the humidity in two separate zones, a Primary and Secondary Zone. The dehumidifier will dehumidify the Primary Zone as the first priority, and will switch to the Secondary Zone after the dehumidification needs of the Primary Zone have been satisfied.
PAGE 13
MODEL 76 – EXTERNAL CONTROL OR CRAWL SPACE/SEALED ATTIC CONTROL AND WIRING Note: Use 18-22 AWG wire for control wiring. The Model 76 uses a normally open (NO), dry contact (i.e. not a triac or other semiconductor) relay to complete the circuit between the DH terminals of the dehumidifier control.
PAGE 14
WIRING THE DEHUMIDIFIER TO THE HVAC SYSTEM AND ZONE DAMPERS Note: Use 18-22 AWG wire for wiring to HVAC system and zone dampers.
