VENTILATION
The dehumidier can activate a normally closed damper to
bring in outdoor air through a fresh air intake duct. This feature
cannot be used when a Model 76 has been installed in a
remote control application and should not be used in two-zone
installations.
1. Install the Fresh Air Inlet (FAI) duct and damper as shown in
FIGURE 23 and FIGURE 24.
2. Install the Outdoor Temperature Sensor (ODT) as shown in
FIGURE 25 and FIGURE 26 – only needed if ventilation will be
limited during high or low outdoor temperature conditions.
