2.4 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
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.
2.5 Cold Climate Considerations
NOTE: It is recommended that these precautions be taken for units being installed in areas where snow
accumulation and prolonged below freezing temperatures occur.
•
Units should be elevated 3-12 inches above the pad or roof top, depending on local weather. This additional
height will allow drainage of snow and ice melted during defrost cycle prior to its refreezing. Ensure that drain
holes in unit base pan are not obstructed preventing draining of defrost water.
•
If possible, avoid locations that are likely to accumulate snow drifts. If not possible, a snow drift barrier should
be installed around the unit to prevent a build-up of snow on the sides of the unit.
Section 3. Unit Preparation
3.1 Prepare The Unit For Installation
STEP 1 - Check for damage and report promptly to the carrier any damage found to the unit.
Section 4. Setting the Unit
4.1 Pad Installation
When installing the unit on a support pad, such as a concrete slab, consider the following:
• The pad should be at least 1" larger than the unit on all sides.
• The pad must be separate from any structure.
• The pad must be level.
• The pad should be high enough above grade to allow for drainage.
• The pad location must comply with National, State, and Local codes.
