If you have the installation guide, it probably has good instructions ....
First, of course, make sure the circuit breaker is switched off.
On the switch - whatever wire is coming into the current switch from the breaker box, disconnect it, attach two 'pigtail' wires to it with a wire nut and connect those two wires to the bottom terminal on the two new switches. On the sheathed electrical cable going to the fan/light (black/red/white/copper) - connect the black wire to the top terminal of one switch. Connect the red wire to the top terminal of the other switch. (The white and copper wires go directly from the breaker box to the fan/light assembly - they shouldn't need to be changed from their current wiring.)
On the fan - (white and copper can stay as they are) I'm assuming that the black wire is currently wired to the fan/light and the red wire is capped. The black wire is probably connected to two wires - one is black and one is some other color (probably striped or blue? .. maybe red or orange ... there should only be three wires - black, white and one other.) Connect the black sheathed electrical cable wire to the black fan wire and connect the red sheathed electrical cable wire to the other fan/light wire.
Flip the switch for some high-voltage fun!
This is assuming that the fan/light is wired as simply as I think it is ... again, the installation manual would be helpful here, especially if you're not too familiar with electrical work.
