Installation Instructions

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 control board access panel to a
wall and a minimum of 24 in. on the adjacent side of control board access panel.
Maintain a distance of 24 in. between units.
Position unit where 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 additional height will allow drainage of
snow and ice melted during defrost cycle prior to its refreezing. Ensure
that drain holes in unit base pan are not obstructed, which could prevent
the drainage of defrost water (Fig. 5).
 If possible, avoid locations that are prone to 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.

Corrosive Environment
NOTICE:
 Exposure to a corrosive environment may shorten the life
of the equipment, corrode metal parts, and/or negatively
affect unit performance.
Corrosive elements include, but are not limited to: sodium chloride, sodium
hydroxide, sodium sulfate, and other compounds commonly found in ocean water,
sulfur, chlorine, fl uorine, fertilizers, and various chemical contaminants from
industry/manufacturing plants. If installed in areas which may exposed to corrosive
environments, special attention should be given to the equipment placement and
maintenance.
 Lawn sprinklers/hoses/waste water should not spray directly on the unit
cabinet for prolonged periods of time.
In coastal areas: locate the unit on the side of the building away from the

waterfront.
Fencing or shrubbery may provide some shielding protection to the unit,

however minimum unit clearances must still be maintained.
Approximately every three months, wash the outdoor coil and any

exposed cabinet surfaces.
