15.1 Cleaning the Unit

CAUTION

Clean the unit regularly to keep dust from obstructing its air vents. If the vents become
blocked, reduced cooling inside the unit may cause equipment damage or other issues..

Important

To clean the unit, moisten a soft cloth with water or neutral detergent and lightly wipe it clean.
Never use detergents or cleansers that contain benzene, alcohol, acetone, ether, ketones,

paint thinner, or gasoline. Doing so may cause discoloration or deformation of shape of the
unit.
