2.3 Suggested Locations for Best Reliability
Ensure the top discharge area is unrestricted for at least
five (5) feet above the unit.
Three (3) feet clearance must be provided in front of the
control box (access panels) and any other side requiring
service.
It is not recommended to install in a location where noise
may distract the building occupants. Some examples of
these types of locations are sleeping quarters and by
windows of a living area. Please discuss location with the
building owner prior to installation.
Avoid locations such as near windows where condensa-
tion 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.
