be objectionable.
• Avoid locations near windows and similar areas where
condensation and freezing defrost vapor can annoy a
customer.
• Position the outdoor unit a minimum of 12" from any wall or
surrounding shrubbery to ensure adequate airflow.
• Outdoor unit location must be far enough away from any
structure to prevent excess roof runoff water or icicles from
falling directly on the unit.
