IMPORTANT INFORMATION
ABOUT EFFICIENCY AND
INDOOR AIR QUALITY
Central cooling and heating equipment
is only as efficient as the duct system
that carries the cooled or heated air. To
maintain efficiency, comfort and good
indoor air quality, it is important to have
the proper balance between the air
being supplied to each room and the air
returning to the cooling and heating
equipment.
Proper balance and sealing of the duct
system improves the efficiency of the
heating and air conditioning system and
improves the indoor air quality of the
home by reducing the amount of
airborne pollutants that enter homes
from spaces where the ductwork and / or
equipment is located. The manufacturer
and the U.S. Environmental Protection
Agency’s Energy Star Program
recommend that central duct systems be
checked by a qualified contractor for
proper balance and sealing.

site, remove carton taking care not to
damage unit.
• Check the unit rating plate for unit
size, electric heat, coil, voltage,
phase, etc. to be sure equipment
matches what is required for the job
specification.
• Read the entire instructions before
starting the installation.
• Some building codes require extra
cabinet insulation and gasketing
when unit is installed in attic
applications.
• If installed in an unconditioned space,
apply caulking around the power
wires, control wires, refrigerant tubing
and condensate line where they enter
the cabinet. Seal the power wires on
the inside where they exit conduit
opening. Caulking is required to

condensate from forming inside the
unit, control box, and on electrical
controls.

• ANSI/NFPA No. 70-(Latest Edition)
National Electrical Code.
• NFPA90A Installation of Air
Conditioning and Ventilating
Systems.
• NFPA90B Installation of warm air
heating and air conditioning systems.
• The equipment has been evaluated in
