My hampton Bay ceiling fan came without installation instructons and no manual.
Where can I download installation instructions?

Here are generic instructions:

Ceiling Fan Wiring - Ceiling Fans N More (http://www.ceiling-fans-n-more.com/ceiling-fan-wiring.php)

Otherwise, contact the manufacturer, their number is in our sticky.
