Electrical Wiring Diagram
1. When installing ductwork, use the shortest
possible runs, 2 diameter radius elbows and
maximum 30° branch entries. Avoid the use of
tees. Connect the piping joints with sheet metal
screws, rivets or solder. Finish each joint with
a single wrap of duct tape.
2. Ductwork must be properly sized for air
velocities recommended for the material being
conveyed.
If the unit is operated with more than
maximum permissible inlet area
(specified by your sales
representative), the fan motor may
become overloaded or dust may settle
out due to low carrying velocities.
Various inlet sizes are available.
Specify size required.
