4 Remove outlet box cover by pulling downward while
simultaneously pushing in side of cover at indicated point to
release locking tab. Connect wire from wall switch to motor
leads and light receptacle wires using approved wire connector -
white to white, black to black. Models A664IC, MM664IC,
MM667IC, and MM667ICF Fan/Lights can be wired so that
fan and light function independently of each other or wired so
that when light is on the fan is on. (See the wiring diagrams
on the next page.) Connect ground wire to green screw in
outlet box. Replace outlet box cover insuring locking tab is
engaged.
5. Use appropriate size duct for best performance. Model MM648
uses 3” duct. Model MM748, MM748H, A664IC, MM664IC,
MM667IC, and MM667ICF uses 4” duct.
IMPORTANT: Be sure nothing obstructs the discharge of the fan.
Take precautions to ensure that insulation does not get into duct
work or fan discharge opening.
NOTE: Numbers 6 thru 9 apply to models MM664IC, MM667IC and MM667ICF only.
