Series Solid State Universal
Bun Toaster
Model No. 411-MSLFCE

Model 411-MSL Series Solid State Universal Bun
Toasters include the latest enhancements to pro­duce perfectly caramelized buns. The digital read­out continuously displays the actual temperatures of
the platens throughout operation. Now with long-life,
reliable solid state temperature controls, the
411-MSL Series Toaster maintains a much tighter
temperature swing resulting in more consistent
color, texture and internal bun temperature. Simple
to use controls allow the operator to adjust the set
point temperature by one degree increments and
adjust the toasting cycle by one second increments.
Calibration is made easy via the calibration mode
and the time/temp readout.

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

SET-UP

3. During the pre-heat cycle, the display will read ­L O -. When the platen temperature reaches

149° C, the display will begin to show the actual
platen temperatures throughout the toasting
cycles. See figure 2.
