For correct operation and uniform temperature distribution it is essential to
maintain free air circulation throughout the oven. The contents of the oven should
therefore not be packed tightly nor should they be placed directly against any of
the heating ribs either to the sides, top or bottom of the oven. (Note the loading
diagrams on ihe ovens).
When putting the shelves into the apparatus please bear in mind that there is a
little air gap between the rear of the working chamber and the shelf in order to
permit better air circulation.
For the maximum number of shelves possible together with the permissible loads
see schedule.
in certain situations where, for example, the load is packed tightly and the
ventilation slide is fully open it is possible that the unit will control at a temperature
below that set on the thermostat. In order to compensate it may be necessary to
increase the thermostat setting until the desired temperature is shown on the
digital display 7.
The following schedule gives recommended loading levels which will ensure
homogeneous temperature distribution within the working chamber.
