8) Places exposed to oil splashes or steam (e.g. kitchens and machine plants.)
Installation and use at such places will incur deteriorations in the performance or corrosion with the heat exchanger or damage
in molded synthetic resin parts.
9) Places where corrosive gas (such as sulfurous acid gas) or inflammable gas (thinner, gasoline, etc.) is generated or remains.
