How do I set the timer and can I use it as a delay timer?

Press the Timer button to activate the timer, then continue pressing it to select your desired time from 1 to 24 hours. The unit can also be pre-set as a delay timer by pressing the Timer button while the unit is plugged in but not running, then selecting the desired delay time. To cancel a pre-set delay timer, press the Power On/Off button to turn the unit on, then press it again to turn it off. (Page 11)
