INSTALLATION INSTRUCTIONS

INSPECT NEW UNIT

After uncrating unit, inspect thoroughly for hidden dam-
age. If damage is found, notify the transportation compa-
ny 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 in-
structions packaged with the kit or accessory when instal-
ling.
The weight of the product requires careful and proper
handling procedures when lifting or moving to avoid per-
sonal 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 Na-
tional Electric Code (NEC) for special requirements.
Improper installation, adjustment, alteration, service or
maintenance can void the warranty.
LOCATION
Check local codes for regulations concerning zoning,
noise, platforms, and other issues.
Locate unit away from fresh air intakes, vents, or bed-
room 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).
CLEARANCES
Nominal minimum clearances are 48 inches above unit
for discharge air and 18 inches 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 paral-
lel 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 cor-
ner 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 fence post
should be a minimum of 6 inches from the unit.
Do not install unit under roof overhangs unless gutters are
present. A minimum vertical clearance of 48 inches is re-
quired to the overhang.

R−410A Split System Air Conditioner
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to turn off the main (remote) electrical dis-
connect device could result in personal injury or
death.
Before installing, modifying or servicing system,
turn OFF the main (remote) electrical disconnect
device. There may be more than one disconnect
device.
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.
Locate unit away from recessed or confined areas where
recirculation of discharge air may occur (refer to CLEAR-
ANCES section of this document).
Roof−top installation is acceptable providing the roof will
support the unit and provisions are made for water drain-
age and noise/vibration dampening.
NOTE: Roof mounted units exposed to wind may require
wind baffles. Consult the manufacturer for additional in-
formation.
Inside corner locations on single story structures require
evaluation. Large overhanging soffits may cause air recir-
culation in a corner area even though recommended mini-
mum 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 between units.
Provide minimum service clearance of 24 inches from
control box corner and side service panel.
Refer to Figure 1.
