1. Unit supplied supply grilles wil be supplied as double-deflection type.
2.Grilles for unequal airflow applications (i.e. unit-mounted plus ducted supply) shall be provided with integral opposed-blade dampers.
3. All grilles will be supplied in standard “Appliance White” painted finish.
4. Grilles are shipped loose, for field installation upon completion of cabinet/ductwork/drywall installation.
5. Top opening size does not change. When combined with any other discharge arrangement, shallbe be included in determining horizontal
opening grille size.
6. Openings marked ‘Not Available’ result in face velocities outside the recommended 300-500 FPM range.
7. Hi-Static Blower option is not recommended or single horizontal discharge openings with unit mounted supply grille.

1. Tabulated Face velocities do not account for supply grille free area factor. Face velocities at supply grille will be higher depending on grille type.
2.Face velocities are based on the nominal rated CFM and in feet per minute (FPM).
3. Face velocities are calculated by taking the averate across all openings. Tabulated top opening face velocity is only for units with single Top
Opening and no horizontal openings.
