Operating instructions
Temperature The ovens can be fitted with temperature recorder 11 as
recorder shown in fig. d. The sensor of the operational controller
(accessory) is used as the temperature sensor.
Full instruction manuals are supplied with the recorder.
Fresh air The fresh air flap in the vent tube is operated by the
ventilation slide control 8. In position 0 the flap is closed, giving
free internal convection circulation on Series UE, BE
and motorised fan recirculation on ovens Series ULE. By
opening the flap the air in the working space can be rene-
wed to a limited extent.
Position 6: Maximum entry of fresh air (but not operation
with fresh air
only!).
Intermediate positions permit selec-
tion of the appropriate mixing ratio.
Important: With a large proportion of fresh air the
selected setpoint temperature may not always be reached. In
that case the air flap should be closed slightly in order
to compensate with a higher heating power for the energy
loss caused by the fresh air intake.
loading Ovens described in this instruction manual must not be used
for drying or heating items giving off vapours which are
inflamnable when mixed with air.
Important

The load must not be packed too tigthly in order to ensure
free air circulation. Do not place anything on the bottccn,
against the sides or underneath the top of the working
space (heating
ribs).
For maximum number of shelves and permitted loading see
page 14.
With unsatisfactory loading (packed too tightly) and the
flap completely open it is possible that the oven may take
a very long time to reach the selected temperature.
When the oven is started up for the first time it should be
run under supervision until steady conditions are reached.
