PLAN THE INSTALLATION

The unit can

be installed

anywhere

between ceiling

joists using

mounting

brackets

provided.

Install in a ﬂ at

ceiling only.

Typical Installation

Ducting has a strong effect on the air ﬂ ow, noise and energy use of

the fan. Use the shortest, straighest duct routing possible for best

performance, and avoid installing the fan with smaller ducts than

recommended. Insulation around the ducts can reduce energy loss

and inhibit mold growth. Fans installed with existing ducts may not

achieve their rated airﬂ ow. The unit will operate most quietly and

efﬁ ciently when located where the shortest possible duct run and

minimum number of elbows will be needed.

Plan to supply the unit with proper line voltage and appropriate power cable.
