EXTERIOR AND IN-LINE BLOWER SELECTION WC45E Series
CAUTION: To reduce risk of fi re and electric shock, install this range hood only with
Exterior Blower Models EB6, EB9, EB12 or EB15, and
ILB9 or ILB11. Other blowers cannot be substituited.
The blower must be UL listed for Canadian and U.S. use, and evaluated for use with solid
state speed control, rated 120V, 60 Hz, 6.0 A max.
INSTALL THE DUCTWORK WC45E Series
NOTE: To reduce the risk of fi re, use only metal ductwork.
1. Choose the location where the Exterior Blower or In-Line Blower will be mounted. See
illustrations below for mounting location suggestions and restrictions.
2. A straight, short duct run will allow the hood to perform most effi ciently.
3. Long duct runs, elbows and transitions will reduce the performance of the hood. Use as
few of them as possible. Larger ducting may be required for best performance with long
duct runs.
4. After the Exterior or In-Line Blower has been installed, connect round metal ductwork
and work back towards the hood location. Use duct tape to seal joints between ductwork
sections.
