The location of the combination supply and return diffuser should
not exceed 10 feet [3.05 m] above the floor level for units @ 1000 CFM
[472 L/s] or less and 12 [3.66 m] to 14 feet [4.27 m] above the floor level
for units with CFM greater than 1000 [472 L/s]. If the diffuser is installed
with a greater distance than recommended above, the supply air may
become stratified above the required comfort area causing uncomforta-
ble conditions.

Designed to convert a side by side or an over and under arrange-
ment into a concentric distribution of air. The diffuser is flush
mounted, completely insulated, assembled, and internally baffled
to provide four way supply air distribution with a center return. To

[1.22 m] suspended ceiling grid, the diffuser includes adjustable
supply louvers, hanging rings, anti-sweat gasket, and round
flanges for use with flexible ducts.
