platforms or supports. Refer to figure 4 for mandatory
installation clearance requirements.

POSITIONING CONSIDERATIONS
Consider the following when positioning the unit:
S
Some localities are adopting sound ordinances based
on the unit's sound level registered from the adjacent
property, not from the installation property. Install the
unit as far as possible from the property line.
S
When possible, do not install the unit directly outside
a window. Glass has a very high level of sound
transmission. For proper placement of unit in relation
to a window see the provided illustration in figure 5.

PLACING OUTDOOR UNIT ON SLAB
When installing a unit at grade level, the top of the slab
should be high enough above the grade so that water from
higher ground would not collect around the unit as
illustrated in figure 5.
Slab may be level or have a slope tolerance away from the
building of not more than two degrees, or 2 inches per 5
feet (51 mm per 1524 mm) as illustrated in figure 5.
INSTALLING OUTDOOR UNIT ON ROOF
Install the unit at a minimum of 4 inches (102 mm) above
the surface of the roof. Ensure the weight of the unit is
properly distributed over roof joists and rafters. Redwood
or steel supports are recommended. Refer to figure 5,
detail c, for rooftop wind barrier considerations.
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil and 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.
