which can enter the unit. Once in the unit, such animals
can cause malfunctions, smoke or fire when making
contact with electrical parts.

Avoid placing the user interface in a place where it can be
splashed with water. Water entering the machine may
cause an electric leak or may damage the internal
electronic parts.

Incomplete drainage may cause the building, furniture, etc.
to get wet.
