Direct Sunlight, Rain, Snow and Ice Protection
• If the outdoor unit is subjected to prolong exposure to
direct sunlight with temperatures over 100°F (38°C) a
canopy is recommended as illustrated in “Figure 19.
Outdoor Unit on Pedestal and Protective Canopy” or
“Figure 24. Dog House-Style Shelter” on page 16
IMPORTANT
The construction of a canopy or shade is necessary
because of an ambient limit control set to 122°F (50°C)
to protect the electronics. If the outdoor unit is placed in
direct sunlight it is possible that the limit may activate and
shut down the unit.
• Place unit away from overhanging roof lines which
would allow water or ice to drop on, or in front of, coil
or into unit. Construct a canopy as illustrated in “Figure
19. Outdoor Unit on Pedestal and Protective Canopy”
• The unit base should be elevated above the depth of
average snows as illustrated in “Figure 20. Outdoor
Unit on Brackets above Snow Line”
• In heavy snow areas, do not place the unit where drift-
ing will occur as illustrated in “Figure 21. Outdoor Unit
Air Flow Obstructed by Snow”
• Carefully consider how to manage defrost water dis-
posal to prevent ice from blocking walkways or creat-
ing a safety hazard near the outdoor unit as illustrated
in “Figure 22. Avoid Defrost Water Ice Hazard”
