• Avoid installing the outdoor unit near a bedroom or
other places where noise may cause a problem.
• There must be sufcient space to carry the unit into
and out of the site.
• There must be unobstructed air ow around the air
inlet and the air outlet.
• The unit must not be installed in areas where a am-
mable gas leak may occur.
• Install the outdoor unit a minimum of 3 feet (1m) away
from any antenna, power cord (line), radio, telephone,
security system, or intercom. Electrical interference
and radio frequencies from any of these sources may
affect operation.
• Since water drains from the outdoor unit during vari-
ous stages of operation, do not place anything which
may be damaged by moisture under the unit.
Direct Sunlight and Rain 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 17.
Outdoor Unit on Pedestal and Protective Canopy”or
“Figure 18. Dog House-Style Shelter”.

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.
Buried Refrigerant Pipe Protection
• All refrigerant lines must be insulated regardless of if
it is buried.
• In addition to insulating each line of piping, buried
lines must rest inside a sealed, watertight conduit.
• The conduit must be designed so it cannot collect and
retain water.
Securing the Outdoor Unit
Slab or Roof Mounting
Install the unit a minimum of 4 inches (102 mm) above
the roof or ground surface to avoid debris build-up around
the unit. Place the unit above a load bearing wall or area
of the roof that can adequately support the unit. Consult
local codes for rooftop applications.
CAUTION
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roong material may absorb oil. This will cause
the rubber to swell when it comes into contact with oil.
The rubber will then bubble and could cause leaks.
Protect the roof surface to avoid exposure to refrigerant
and oil during service and installation. Failure to follow
this notice could result in damage to roof surface.
Securing Outdoor Unit to Slab, Frame, or Rails
If the outdoor unit is installed on a eld-provided slab or
frame, use lag bolts or equivalent to secure the outdoor
unit to the slab or frame.
