CARDBOARD PROTECTOR |
|
1. Install mounting brackets.
Slide the adjustable mounting brackets into the bracket channels on the housing.
Bend the tabs on the cardboard protector and insert protector into opening in housing.
NOTE: The cardboard protector shields the inside of the housing from drywall spray and construction dust. Do not remove it until after construction is completed.
1/8" GAP |
2. Mark mounting location.
Position unit between joists and extend mounting brackets.
IMPORTANT: Position brackets so there will be an 1/8” gap between bottom of housing and ceiling material. Mark the top of keyhole slot on all four mounting brackets.
3. Pound in nails.
Remove unit temporarily, and pound nails partially into joists at all four marked locations.
