• 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
ovens, 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.
