Warning
This unit is not explosion-proof. Do not use in the presence of
flammable or combustible materials; fire or explosion may result. Unit
contains components that may ignite such materials. Before operating
oven, always observe the following safety precautions:
• Fumes and spillage from acidic solutions cause corrosion of the
stainless steel chamber. Care should be taken to maintain a neutral
pH at all times.
• The heater for the oven is in the bottom of the unit. Surface
temperatures at the bottom cover of the unit may be higher than
set point temperature. For example: A plastic container on the
heater cover may become hot enough to melt/burn the container at
settings below the melting point of plastic. Do not place items on
the heater cover.
