INSTALLATION INSTRUCTIONS

INSPECT NEW UNIT

After uncrating unit, inspect thoroughly for hidden

damage. If damage is found, notify the transportation

company immediately and file a concealed damage

claim.

SAFETY CONSIDERATIONS

Consult a qualified installer, service agency, or the

dealer/distributor for information and assistance. The

qualified installer must use factory authorized kits and

accessories when modifying this product. Refer to the

individual instructions packaged with the kit or accessory

when installing.

The weight of the product requires careful and proper

handling procedures when lifting or moving to avoid

personal injury. Use care to avoid contact with sharp or

pointed edges.

Follow all safety codes. Wear safety glasses, protective

clothing, and work gloves. Use a heat sinking material −

such as a wet rag − during brazing operations. Keep a fire

extinguisher available. Consult local codes and the

National Electric Code (NEC) for special requirements.

Improper installation, adjustment, alteration, service or

maintenance can void the warranty.

CAUTION

CUT HAZARD

Failure to follow this caution may result in proper-

ty damage.

Sheet metal parts may have sharp edges or burrs.

and gloves when handling parts.

WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in

personal injury or death.

Before installing, modifying or servicing system,

main electrical disconnect switch must be in the

OFF position. There may be more than 1

disconnect switch. Lock out and tag switch with a

suitable warning label.

CAUTION

PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in proper-

ty damage

R−410A systems operate at higher pressures than

R−22 systems. When working with R−410A sys-

tems, use only service equipment and replace-

ment components specifically rated or approved

for R−410A service.

LOCATION

Check local codes for regulations concerning zoning,

noise, platforms, and other issues.

Locate unit away from fresh air intakes, vents, or

bedroom windows. Noise may carry into the openings

and disturb people inside.

Locate unit in a well drained area, or support unit high

enough so that water runoff will not enter the unit.

Locate unit away from areas where heat, lint, or exhaust

fumes will be discharged onto unit (as from dryer vents).

Locate unit away from recessed or confined areas where

recirculation of discharge air may occur (refer to

CLEARANCES section of this document).

Roof−top installation is acceptable providing the roof will

support the unit and provisions are made for water

drainage and noise/vibration dampening.

NOTE: Roof mounted units exposed to wind may require

wind baffles. Consult the manufacturer for additional

information.

CLEARANCES

Nominal minimum clearances are 48 inches (1.2m)

above unit for discharge air and 18 inches (457mm) on

each side of the coil for intake air. Clearance on any one

side of the coil (normally between unit and structure) may

be reduced to 6 inches. Nominal minimum clearances are

based on a solid parallel object such as a wall or roof

overhang.

The clearance may be reduced for a single object with

small surface area, such as the end of a wall, outside

corner of a wall, fence section, post, etc. As a general

rule, the minimum clearance from the unit should equal

the width of the object. For example, a 6 inch (152mm)

fence post should be a minimum of 6 inches (152mm)

from the unit.

Do not install unit under roof overhangs unless gutters are

present. A minimum vertical clearance of 48 (1.2m)

inches is required to the overhang.

Inside corner locations on single story structures require

evaluation. Large overhanging soffits may cause air

recirculation in a corner area even though recommended

minimum clearances are maintained. As a guide, locate

the unit far enough out so that half of the discharge grille is

out from under the soffit.

When placing two or more units side−by−side, provide a

minimum of 18 inches (457mm) between units.

Provide minimum service clearance of 24 inches

(610mm) from control box corner and side service panel.

Refer to Figure 1.
