Operation
Caution
Do not use in the presence of flammable or combustible materials
or explosive gases. Do not use in the presence of pressurized or sealed
containers - fire or explosion may result, causing death or severe injury.
s
Caution
Do not heat any substance above a temperature which will cause
it to emit toxic fumes - death or severe injury may result.
s
Caution
Do not operate the oven at temperatures above the upper limit
(220°C) stated in this manual; doing so will void the warranty.
s
Caution
When the oven is operating at high temperatures, do not touch
the surfaces of the oven; they become quite warm.
s
If it is necessary to set temperature before loading the oven, turn the power
switch ON and note that the power switch is lit. Rotate the thermostat
knob to approximate the desired setting. The heater indicator status lamp
will remain lit until the chamber temperature approaches the thermostat
setting. Wait several heat cycles until the temperature has stabilized.
Check the dial thermometer and rotate the thermostat knob clockwise to
raise the setpoint or counterclockwise to lower it, as required. After oven
temperature has stabilized, check the dial thermometer again and make
further thermostat adjustments until the thermometer consistently shows
the desired operating temperature. Turn the power switch OFF and allow
the oven to cool down, or if a batch is ready for baking, the oven can be
loaded immediately.
