NOTES:
1.
Unit mounted supply grilles are supplied as double-deflection type.
2.
Grilles for unequal airflow applications (for example, unit mounted plus ducted supply) are provided with integral opposed blade dampers.
3.
All grilles are 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, it is 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 or single horizontal discharge openings with unit mounted supply grille are not recommended. Hi-static blower op-
tion is only recommended for units with top supply/opening and appropriate higher external static requirements.

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