SAFETY CONSIDERATIONS
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in proper-
ty damage

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.
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.
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.
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. Lock out and tag switch with a suitable
warning label.
CLEARANCES
When installing, allow sufficient space for airflow
clearance, wiring, refrigerant piping, and service. Allow
24 in. (610 mm) clearance to service end of unit and 48 in.
(1219.2 mm) above unit. For proper airflow, a 6 in. (152.4
mm) clearance on one side of unit and 12 in. (304.8 mm)
on all remaining sides must be maintained. Maintain a
distance of 24 in. (609.6 mm) between units or 18 in.
(457.2 mm) if no overhang within 12 ft. (3.66 m). Position
so water, snow, or ice from roof or eaves cannot fall
directly on unit.
