DETAIL A
INSTALL UNIT AWAY
FROM WINDOWS
TWO 90 ELBOWS INSTALLED IN LINE SET
Unit Placement
See Unit Dimensions on page 4 for sizing mounting slab,
platforms or supports. Refer to page 3 for mandatory instal-
lation clearance requirements.
CAUTION
In order to avoid injury, take proper precaution when
lifting heavy objects..
POSITIONING CONSIDERATIONS
Consider the following when positioning the unit:
• Some localities are adopting sound ordinances based on
the unit's sound level registered from the adjacent prop-
erty, not from the installation property. Install the unit as
far as possible from the property line.
• When possible, do not install the unit directly outside a
window. Glass has a very high level of sound transmis-
sion. For proper placement of unit in relation to a window
see the provided illustration in figure 3, 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 3, detail B.

INSTALL UNIT LEVEL OR, IF ON A SLOPE, MAINTAIN SLOPE TOLERANCE
OF 2 DEGREES (OR 2 INCHES PER 5 FEET [50 MM PER 1.5 M]) AWAY
FROM BUILDING STRUCTURE.
BUILDING
STRUCTURE
ROOF MOUNTING
Install the unit a minimum of 6 inches (152 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.
If unit coil cannot be mounted away from prevailing winter
winds, a wind barrier should be constructed. Size barrier
at least the same height and width as outdoor unit. Mount
barrier 24 inches (610 mm) from the sides of the unit in the
direction of prevailing winds.
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil, causing the
rubber to swell. Bubbles in the rubber roofing material
can 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.
