* The front face of the unit, installed in a solid panel, has been tested using conditions equivalent
to
the standards shown in the
“Environmental conditions”. Even though the level of resistance unit
is
equivalent to these standards, oils that should have no effect on the panel can possibly harm the
unit. This can occur in areas where either vaporized oils are present, or where low viscosity cutting
oil
are allowed to adhere to the unit for long periods of time. If the front face protection sheet on the
panel
becomes peeled off, these conditions can lead 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
the panel, the original level of the protection cannot be guaranteed.
