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.
Installation and use at such places will cause corrosion in the heat exchanger and damage in molded synthetic resin parts.
10) Place adjacent to equipment generating electromagnetic waves or high-frquency waves such sa in hospitals. Generated
noise may cause malfunctioning of the controller.
