Supply Air Grill Installation

Bard model SGR-5W grille is custom designed for
utilization with Bard wall-mount unit WR**AP* for
optimizing the air flow pattern and distribution to
minimize recirculation issues, and optimizing airflow
patterns within the shelter. It is engineered to ensure
that the distributed air is forced in a downward and
outward direction to eliminate obstructions and such
from causing the distributed air from stratifying close
to the unit and getting drawn back into the return air
opening. With the optimized air pattern, the shelter
should experience distributed air at the opposite end of
the room.
To accomplish this, the grille has two special features:
1. The grille has a specialty fold-out diverter on
the backside of the grille that directs the supply
airflow in an outward pattern, thereby eliminating
the potential for the obstruction of supply air if

equipment would be directly mounted in front of
the unit. The rear deflectors must be folded out and
secured by the installer with the supplied screws
(see Figure 5).
2. The grille is also equipped with downward curved
diverter blades to ensure a smooth and efficient
means of directing the air pattern in a downward
pattern, and away from being drawn back into
the return air opening. The curved diverter blades
are shipped in the flat position and need to be
folded out to between 75-90° (best tuned to each
individual structure). See Figures 6 and 7.
