UNIT SPECIFICATIONS
These are 110 – 120 volt units. 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 and
at nominal voltage. The temperatures specified are determined in accordance to factory standard following
DIN 12880 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.
TEMPERATURE
Range, Stability, and Uniformity
Model Range Stability Uniformity
CVO-2-HT Ambient +20°to 220°C ± 0.2°C @ 150°C ±6% of Set Point
CVO-5-HT Ambient +20°to 220°C ± 0.25°C @ 150°C ±6% of Set Point
The maximum temperature is dependent on the type of door gasket installed. The oven comes with a
silicon gasket installed that is rated to 230°C. See page 70 for the temperature ranges of other gasket
types.
