Preparation And Wiring Diagrams - Delta SMT150LED User Manual

PERPARATION AND WIRING DIAGRAMS
Proper insulation around the fan to minimize building
heat loss and gain. The ducting from this fan to the
outside of the building has a strong effect on the air
flow, noise and energy use of the fan. Use the shortest,
straightest 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 air flow.
Connect wiring
1. Follow all local electrical and ANSI/NFPA70.
2. NEVER place a switch where it can be reached
from a tub or shower.
3. Connect wires as shown in wiring diagrams.

4.  U sing wire nuts (not provided), connect the house
power cable and LED cable to the ventilating fan
wires.
5. 14 AWG (2.1 mm2) is the smallest conductor that
shall be used for branch-circuit wiring.
