excessive loads on the motor resulting in higher than
normal operating temperatures and possible shortened
service life. It is recommended that the blower compartment

Inspect the condensate drain and outdoor coil at the
beginning of each cooling season. Remove any debris.
Clean the outdoor coil and hail guard louvers (optional)
as necessary using a mild detergent and water. Rinse
thoroughly with water.
