OPERATION

To determine the appropriate calibration for your product, begin by setting the timer at 6, which is approximately a 60
second cycle—initiate cycle by pressing toast switch. If a darker finish is desired, advance the control to a higher
setting. Reduce the setting for a lighter finish. Cycle times will vary depending on product weight and compostition.
When melting cheese, begin with a lower setting. At the completion of the toast cycle, remove product. The unit is
designed for consecutive cycles as demand requires.
