Table 5. Suggested Locations for Best Reliability
•
Ensure the top discharge area is unrestricted for at least 5
feet above the unit.
•
Provide at least 3 feet clearance in front of the control box
(access panels) and any other side requiring service.
•
Do not locate close to bedrooms as operational sounds may
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.
•
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.
