1.4 Capacities, Weights and Filter Sizes
Complete electrical and performance specications and dimensional drawings are in the Product Data
Sheet.
Note: Follow local codes and standards when designing duct runs to deliver the required airow.
Minimize noise and excessive pressure drops caused by duct aspect ratio changes, bends, dampers and
outlet grilles in duct runs.

Ratings are with no outside air. Performance will be affected by altitude.
Ratings are at 230 volts for 208/230 volt units (“A” & “C” models) and 460 volts for “D” models. Operation of units at a different volt-
age from that of the rating point will affect performance and air ow.
