outside with the shortest possible duct run and the fewest num-
ber of elbows.

11. Hang unit from nails and use embossed measuring guides to
check if unit will be flush with finished ceiling. Pound nails tight.
For wide joist centers: A #8 x 3/8 self-tapping screw can be used
to join extended brackets together and create a rigid mount. To
ensure a noise-free mount, crimp the bracket channels tightly
around mounting brackets.
