New Outdoor Unit Placement

CAUTION
In order to avoid injury, take proper precaution when
lifting heavy objects.
Remove existing outdoor unit prior to placement of new
outdoor unit. See Unit Dimensions on page 2 for sizing

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

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.

transmission. For proper placement of unit in relation
to a window see the provided illustration in figure 5,
detail A.
PLACING UNIT ON SLAB
When installing unit at grade level, the top of the slab
should be high enough above grade so that water from
higher ground will not collect around the unit. The slab
should have a slope tolerance as described in figure 5,
detail B.
ROOF MOUNTING
Install the unit a minimum of 4 inches (102 mm) above the
roof surface to avoid ice build−up around the unit. Locate
the unit above a load bearing wall or area of the roof that
can adequately support the unit. Consult local codes for
rooftop applications. See figure 5, detail C for other roof top
mounting considerations.
