mm) and the final side may be 6 in, (152 mm)

48 in, (1219 ram) 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.

Figure 9. Elevated Slab Mounting using Feet

Extenders (Larger Base Units)

If additional elevation is necessary, raise the unit by

extending the height of the unit support feet. This may be

done with 2" SCH 40 female threaded adapter. The

specified coupling will fit snuggly into the recess portion of

the feet. Use additional 2" SCH 40 male threaded adapters

which can be threaded into the female threaded adapters

to make additional adjustments to the level of the unit.

NOTE -Keep the height of extenders short enough to

ensure a sturdy installation, If it is necessary to extend

further, consider a different type of field-fabricated

framework that is sturdy enough for greater heights.

STABILIZING UNIT ON UNEVEN SURFACES

To help stabilize an outdoor unit, some installations may

require strapping the unit to the pad using brackets and

anchors commonly available in the marketplace.

If refrigerant lines are routed through a wall, seal and

isolate the opening so vibration is not transmitted to the

building, Pay close attention to line set isolation during

installation of any HVAC system. When properly isolated

from building structures (walls, ceilings, floors), the

refrigerant lines will not create unnecessary vibration and

subsequent sounds.

REFRIGERANT LINE SET

Field refrigerant piping consists of liquid and vapor lines

from the outdoor unit (sweat connections) to the indoor unit

coil (flare or sweat connections). Use Lennox L15 (sweat,

non41are) series line sets, or use field-fabricated

refrigerant lines as listed in table 3.

MATCHING WITH NEW OR EXISTING INDOOR COIL

AND LINE SET

IMPORTANT

When installing refrigerant lines longer than 50 feet, see

the Lennox Refrigerant Piping Design and Fabrication

Guidelines, or contact Lennox Technical Support Product

Applications for assistance. To obtain the correct

information from Lennox, be sure to communicate the

following points:

Model (XP15) and size (e.g. -060) of unit.
