DESCRIPTION
APPLICATION
The motorized fresh air damper WGMFAD is an internally mounted damper designed to bring in up to 25% fresh air. The damper blade is powered by a 24 VAC motor with spring return on power loss. The damper is powered open anytime the unit blower motor is energized.
The amount of outside fresh air brought into the structure is dependent on the supply and return duct static pressure present in the duct system. Refer to Table for ventilation air that will be supplied at different duct static pressure for the model installed. For free blow applications with return air filter grille and supply grille, use 0.00 supply air static pressure and 0.1 return air static pressure.
This ventilation device does not include an exhaust provision. Depending on the tightness of the structure, an independent exhaust provision may be needed to obtain the ventilation air quantities shown.

INSTALLATION Step 1. Disconnect all power to unit before installing WGMFAD. Step 2. Remove vent option door. (See Figure 1.) Remove fresh air damper or blank off plate if installed on vent option door. Step 3. The “exhaust cover plates” must be in place when a WGMFAD is installed. (See Figure 2.)
Manual 2100-362D Page 4 of 10
Step 4. Install WGMFAD with notch in front lip of WGMFAD centered over hole in condenser partition. (See Figure 3A.) Step 5. Position WGMFAD with front lip over condenser partition and front grille. (See Figure 3B.) This is important to insure proper drainage of any water entering damper assembly.

Step 6. Route wires as shown in Figure 3A into unit low voltage terminal strip area. Step 7. Connect black wire to C terminal of low voltage block. Connect red wire to R of low voltage block. Connect orange wire to G terminal of low voltage block. Connect brown/ white wire to “A” terminal of low voltage block. Connect blue wire to W1 terminal of low voltage block. See wall mount low voltage connection diagram in the unit installation instructions for wiring diagram.
Step 8. Check WGMFAD for proper operation. WGMFAD should open whenever there is a call for ventilation (Terminal “A”), and the blower should energize. Step 9. Plug 4 holes in vent option door with plastic plugs provided and replace vent option door.
