UNIT SPECIFICATIONS
Please refer to the oven data plate for individual electrical specifications.
Technical data specified applies to units with standard equipment at an ambient temperature of 25°C
±3° (77°F ±5.4°) and at nominal voltage. The temperatures specified are determined in accordance
with factory standards respecting the recommended wall clearances of 10% of the height, width, and
depth of the inner chamber. All indications are average values, typical for units produced in the
series. We reserve the right to alter technical specifications at all times.
