DUCTING TO HV AC SYSTEM – BASEMENT AND A TTIC INST ALLA TIONS 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 HV AC system air before being discharged into the living space.

WIRING TO THE HVAC SYSTEM WIRING TO ZONE DAMPERS When the dehumidifier is ducted to the HV AC system, it is recommended that it also be wired to the HV AC system as shown in Figure 22 .
SYSTEM SET -UP & CHECKOUT If dehumidifier installation does not include ventilation or zoning and will not be wired to an external control, remote control or the HV AC system, proceed to Installer T est Mode section on page 17. 1. Check all wiring.

VENTILA TION The dehumidifier can activate a normally closed damper to bring in outdoor air through a fresh air intake duct. This feature can not be used when a Model 76 has been installed in a Remote Control application, and is not recommended for two-zone installations.
VENTILA TION (CONTINUED) VENT-AUTO & VENT-TIMED OUTDOOR TEMPERATURE SENSOR INSTALLATION The dehumidifier can ventilate in four modes. V ent-T imed: V entilation occurs based only on time setting; no temperature restrictions. V ent-Auto-B: V entilation prevented when outdoor temperature is below 0°F and above 100°F .
DETERMINE FRESH AIR DELIVERY RATE 1. Measure the negative static pressure of the return system at the location where the fresh air intake duct enters the return duct or dehumidifier inlet. 2. See T able 2 for estimated inlet airflow in CFM, based on duct type, length and available negative pressure.

SEQUENCE OF OPERATION When wired as shown in Figure 26 , the ventilation damper will open whenever there is an HV AC heating (W), cooling (Y) or fan (Gs) call, allowing fresh air to be brought in when the HV AC blower is running (see VENTILA TION WITH AN EXTERNAL CONTROL section below for exceptions).
