from small parts bag. Remove backing and apply two pieces of foam tape equally spaced
along the unit’s mounting flange to be held by the hanging bracket. Apply the other two
pieces of foam over two holes that will be used for fastening, on the other flange. The tape
should be applied in a “U” shape to cushion both the front and back of the integral flanges.
Lift unit and slide unit flange into the hanging bracket. Using metal flat washers, fasten
flange opposite hanging bracket to structure. Safety screws should similarly be installed
passing through the hanging bracket and flange. Make sure the screws, which you must
supply, are properly selected for the loads and substrate involved, 2" x #10 pan head screws
are recommended.
