F.A.S.T’s adjustable cycle timer allows for two purposes. In the hottest environment, if you need to extend the life of your ice, just dial the timer all the way back to allow it to run for 30 seconds every five minutes. For short duration races, leave it at the first click so that the system runs continuously. This is not an adjustable speed control. Speed controllers are hard on motors and pumps, causing pump burnouts.
When the dial first clicks on, the cooler will run non-stop. If you turn the dial all the way up, it will run for 30 seconds every 5 minutes.
