Table 3. Suggested Locations for Best Reliability (continued)
•
A 36” minimum clearance is required on the line voltage electrical
service side access panel to any wall or obstruction.
•
For ease of service maintenance, provide 24” clearance in front of
the control box (access panel) and any other side requiring
service.
•
It is recommended to leave a minimum clearance of 2” above unit
for future top removal.
A 36” minimum clearance is required from
service panel to additional units or other
obstructions.
A 12” clearance is suggested for obstructions
above the unit.
Note: 12” clearance not required with stacking kit.
A 2” minimum clearance is required to allow for
removal of top
Table 4. 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 rooftop,
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 drainage 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.

Table 5. Coastal Considerations
If installed within one mile of salt water, including seacoasts and inland waterways, models with epoxy coated coils are available. Model
numbers with “COT” in the eleventh (11) through thirteenth (13) digits represent epoxy coated coil. These models have an 8 week lead time
after order.
