Even though the level of resistance unit is equivalent to thesestandards, oils that should have no effect on the HMe can possibly harm the unit. This can occur in areaswhere either vaporized oils are present, or where low viscosity cutting oil are allowed to adhere to the unit forlong periods of time. If the front face protection sheet on the HMe becomes peeled off, these conditions canlead to the ingress of oil into the unit and separate protection measures are suggested.If the installation gasket is used for a long period of time, or if the unit and its gasket are removed from thepanel, the original degree of the protection cannot be guaranteed.
