System Description and General Operation
The low split line of the oven allows easy access to the oven facilitating column
exchange and routine maintenance. The temperature within the oven is
controlled by eight active heaters; 3 are built into the base of the oven and 4 in
the oven lid, the eighth heater is mounted directly in front of the fan and it is
this heater that provides the fine control.
Figure 7 on page 14 illustrates the location of the heaters (red lines) in the
oven construction and the airflow around the heaters (black arrows).
