Do not immerse the filter or other resin

Never use water on the motor, the switch,
or the Heat Exchange Element.
Do not use the following items for cleaning. Avoid using heat to dry the filter, as it may
cause changes in shape or quality.

Failure to do so may cause dust and dirt to
build up on the heat exchange element,
lowering its efficiency and rendering it
inoperable.
