ET8 and ET8R ovens (single section oven) are

ET88R ovens. In order to convert an ET8 or ET8R to an
ET88 or ET88R (double section) in the field, disconnect
the electrical supply leads from the old oven and move
the oven away. Locate the new oven (ET8 or ET8R,
bottom section) in the desired location and mount the
old ET8 or ET8R on top of the new oven, following
installation instructions in the Installation and Operation
Manual.
In 220/380 or 240/415 volt models, the oven operates on
either 220 or 240 volts between the neutral and the

wire, independent from grounding wire which is used to
ground the oven frame, be included in the main supply
leads.
