FACTORY PRE-SET

Prince Castle’s Solid State Digital Display toasters are
pre-set at the factory.

If your toaster model is set for a 35 second toast time,
then the temperature is pre-set and calibrated to 425°F
215°C.

If your toaster model is set for a 55 second toast time,
then the temperature is pre-set and calibrated to 400°F
204°C.

SET-UP

1. Refer to the nameplate on the control box for the
proper operating voltage. Connect the toaster to a
grounded receptacle that matches the nameplate
voltage information. Press the power switch to the
on position, allow the unit 30 minutes to reach
operating temperature.

3. During the pre-heat cycle, the display will read ­L O -. When the platen temperature reaches
300° F (149° C), the display will begin to show
the actual platen temperatures throughout the
