3. When the low side system pressures reach 0 psig,
close the vapor line valve.
4. Disconnect all power to the existing outdoor unit.
Check gauges after shutdown to confirm that the
valves are not allowing refrigerant to flow back into the
low side of the system.
5. Disconnect the liquid and vapor lines from the existing
outdoor unit.
6. Remove the existing outdoor unit.

NOTES:
Service clearance of 30 in. (762 mm) must be maintained on one of
the sides adjacent to the control box.
Clearance to one of the other three sides must be 36 in. (914 mm)
Clearance to one of the remaining two sides may be 12 in. (305
mm) and the final side may be 6 in. (152 mm)
48 in. (1219 mm) clearance required on top of unit.
A clearance of 24 in. (610 mm) must be maintained between two
units
Figure 5. Installation Clearances
POSITIONING CONSIDERATIONS
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. 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 6.
Install unit away
from windows
Two 90° elbows installed in line set
will reduce line set vibration.
Figure 6. Outside Unit Placement
PLACING 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 7. 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).
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.

INSTALLING UNIT ON ROOF
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 as illustrated in
figure 8. 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.
