2.3 Location restrictions

Ensure the top discharge area is unrestricted for at least 60 inches above the unit.

Do not locate outdoor unit near bedrooms since normal operational sounds may be

objectionable.

Position unit to allow adequate space for unobstructed airﬂ ow, wiring, refrigerant

lines, and serviceability.

Allow a minimum of 12 in. clearance on one side of access panel to a wall and a

minimum of 24 in. on the adjacent side of access panel.

Maintain a distance of 24 in. between units.

Position unit so water, snow, or ice from roof or overhang cannot fall directly on unit.

See Fig. 3 and Fig. 4.

Cold climate considerations (heat pump only)

Precautions must be taken for units being installed in areas where

snow accumulation and prolonged below-freezing temperatures occur.

 Units should be elevated 3-12 inches above the pad or rooftop, depending

on local weather. This addi-tional height will allow drainage of snow and ice

melted durIng defrost cycle prior to its refreezlng. Ensure that drain holes

in unit base pan are not obstructed, preventing drainage of defrost water

(Fig. 5).

 If possible, avoid locations that are likely to accu-mulate snow drifts. if not

possible, a snow drift barrier should be installed around the unit to prevent

a build-up of snow on the sides of the unit.
