the outdoor coil surface or other parts in the air circuit. Cleaning
should be as often as necessary to keep coil clean. Use a brush,
vacuum cleaner attachment, or other suitable means. If water
is used to clean coil, be sure power to the unit is shut off prior
to cleaning.
NOTE: Exercise care when cleaning the coil so that the coil fins
are not damaged.
Do not permit the outdoor air discharge to be obstructed
by overhanging structures of shrubs.
