MOTORS - Indoor and outdoor fan motors are permanently
lubricated and require no maintenance.
OUTDOOR COIL - Dirt should not be allowed to accumulate on
the outdoor coil surface or other parts in the air circuit. Cleaning
should be as often as necessary to keep the coil clean. Use a
brush, vacuum cleaner attachment, or other suitable means. If
water is used to clean the coil, be sure that the power to the unit
is shut off prior to cleaning.
Exercise care when cleaning the coil so that the coil fins
are not damaged.
Do not permit the hot condenser air discharge to be
obstructed by overhanging structures or shrubs.
