IMPORTANT INFORMATION
ABOUT EFFICIENCY AND
INDOOR AIR QUALITY
Central cooling and heating equipment
is only as efficient as the duct system
t
hat 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.
RECEIVING
Immediately upon receipt, all cartons
and contents should be inspected for
transit damage. Units with damaged
cartons should be opened immediately.
If damage is found, it should be noted
on the delivery papers, and a damage
claim filed with the last carrier.
• After unit has been delivered to job
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
prevent air leakage into and
condensate from forming inside the
unit, control box, and on electrical
controls.

MIGRATION OF DANGEROUS SUBSTANCES, FUMES, AND ODORS INTO LIVING SPACES
CARBON MONOXIDE (CO) IS A COLORLESS, ODORLESS, POISONOUS
GAS THAT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH.
CARBON MONOXIDE CAN BE PRODUCED BY ANY FUEL-BURNING
DEVICE, INCLUDING BUT NOT LIMITED TO:
• MOTOR VEHICLES
• GENERATORS AND OTHER GASOLINE POWERED TOOLS AND
ENGINES
• GAS AND FUEL-OIL APPLIANCES
• CHARCOAL OR GAS GRILLS
•
WOOD OR GAS FIREPLACES AND STOVES
• OUTDOOR CAMPING EQUIPMENT
CARBON MONOXIDE FROM ANY ONE OF THESE DEVICES CAN BE
INADVERTENTLY DRAWN INTO AND DISTRIBUTED THROUGH THE
LIVING SPACE BY THE NORMAL OPERATION OF THE CENTRAL HEATING
/ AIR CONDITIONING SYSTEM (SEE FIGURE 1).
APPLIANCES AND FUEL BURNING DEVICES MUST BE INSTALLED,
OPERATED AND MAINTAINED IN ACCORDANCE WITH THE MANUFAC-
TURER’S INSTRUCTIONS.
GASOLINE-POWERED TOOLS AND MOTOR VEHICLES MUST NOT BE
OPERATED IN ENCLOSED SPACES, SUCH AS BASEMENTS, CRAWL-
SPACES, OR GARAGES, EVEN WITH DOORS AND WINDOWS OR VENTS
OPEN, AS EXHAUST FUMES INCLUDING CARBON MONOXIDE CAN BUILD
UP AND SEEP INTO THE LIVING SPACE THROUGH CRACKS AND
OPENINGS IN THE STRUCTURE. TOXIC FUMES, INCLUDING CARBON
MONOXIDE, CAN ALSO BE DRAWN INTO THE LIVING SPACE THROUGH
OPENINGS AND SEAMS IN THE CENTRAL HEATING AND AIR
CONDITIONING EQUIPMENT AND / OR DUCTWORK.
FOR THESE REASONS, THE U.S. CONSUMER PRODUCT SAFETY
COMMISSION (CPSC) RECOMMENDS THAT EVERY HOME HAVE AT
LEAST ONE CARBON MONOXIDE ALARM INSTALLED IN THE HALLWAY
NEAR THE BEDROOMS IN EACH SEPARATE SLEEPING AREA OF THE
HOME. CARBON MONOXIDE ALARMS SHOULD BE CERTIFIED TO THE
REQUIREMENTS OF THE MOST RECENT UL, IAS OR CSA STANDARD,
AND SHOULD BE INSTALLED, OPERATED AND MAINTAINED IN
ACCORDANCE WITH THE ALARM MANUFACTURER’S INSTRUCTIONS.
