Positioning New Outdoor Unit
CAUTION
In order to avoid injury, take proper precaution when
lifting heavy objects.
See
Unit Dimensions
on page 3 for sizing mounting slab,
platforms or supports. Refer to Figure 4 for mandatory
installation clearance requirements.
SEE NOTES BELOW THIS FIGURE FOR FURTHER DETAILS.

ACCESS LOCATION
Figure 4. Installation Clearances
NOTES:
S
Service clearance of 30 in. (762 mm) must be
maintained on one of the sides adjacent to the control
panel.
S
Clearance to one of the other three sides must be 36
in. (914 mm).
S
Clearance to one of the remaining two sides may be
12 in. (305 mm) and the final side may be 6 in. (152
mm).
S
48 in. (1219 mm) clearance required on top of unit.
S
A clearance of 24 in. (610 mm) must be maintained
between two units.
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.
S
In locating and positioning the unit, take into
consideration where the solar module will be located
and/or how the wire can or will be routed to it.
INSTALL UNIT AWAY FROM
WINDOWS
TWO 90° ELBOWS INSTALLED IN
LINE SET WILL REDUCE LINE SET
VIBRATION.

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 6.
NOTE If necessary for stability, anchor unit to slab as
described in
Stabilizing Unit on Uneven Surfaces on page 9.
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.
