ACCORDANCE WITH THE
UNDERWRITERS LABORATORY
(UL) CERTIFICATION OR THESE
INSTRUCTIONS, CAN RESULT IN
UNSATISFACTORY OPERATION
AND/OR DANGEROUS CONDI-
TIONS AND ARE NOT COVERED
BY THE UNIT WARRANTY.
DUCT LEAKS CAN CREATE AN
UNBALANCED SYSTEM AND
DRAW POLLUTANTS SUCH AS
DIRT, DUST, FUMES AND ODORS
INTO THE HOME CAUSING
PROPERTY DAMAGE. FUMES
AND ODORS FROM TOXIC,
VOLATILE OR FLAMMABLE
CHEM I CALS, AS WELL AS AUTO-
MOBILE EXHAUST AND CARBON
MONOXIDE (CO), CAN BE DRAWN
INTO THE LIVING SPACE
THROUGH LEAKING DUCTS AND
UNBALANCED DUCT SYSTEMS
CAUSING PERSONAL INJURY OR
DEATH (SEE FIGURE 2).
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
GARAGES OR OFF-GARAGE
STORAGE AREAS - ALL JOINTS,
SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST
BE SEALED TO LIMIT THE
MIGRATION OF TOXIC FUMES
AND ODORS INCLUDING CAR -
BON MONOXIDE FROM
MIGRATING INTO THE LIVING
SPACE.
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
SPACES CONTAINING FUEL
BURNING APPLIANCES SUCH
AS WATER HEATERS OR
BOILERS - ALL JOINTS, SEAMS,
AND OPENINGS IN THE EQUIP -
MENT AND DUCT MUST ALSO
BE SEALED TO PREVENT
DEPRESSURIZATION OF THE
SPACE AND POSSIBLE
MIGRATION OF COMBUSTION
BYPRODUCTS INCLUDING
CARBON MONOXIDE INTO THE
LIVING SPACE.
IN COMPLIANCE WITH
RECOGNIZED CODES, IT IS
RECOMMENDED THAT AN
AUXILIARY DRAIN PAN BE
INSTALLED UNDER ALL
EVAPORATOR COILS AND UNITS
CONTAINING EVAPORATOR
COILS AND AIR HANDLERS USED
WITH EVAPORATOR COILS THAT
ARE LOCATED IN ANY AREA OF A
STRUCTURE WHERE DAMAGE TO
THE BUILDING OR BUILDING
CONTENTS MAY OCCUR AS A
RESULT OF AN OVERFLOW OF
THE COIL DRAIN PAN, A
STOPPAGE IN THE PRIMARY
CONDENSATE DRAIN PIPING OR
ANY WATER LEAK POTENTIAL
FROM THE AIR HANDLER.

SAFETY INFORMATION
WHEN AN AIR HANDLER IS
INSTALLED SO THAT SUPPLY
DUCTS CARRY AIR CIRCULATED
BY THE AIR HANDLER TO AREAS
OUTSIDE THE SPACE
CONTAINING THE AIR HANDLER,
THE RETURN AIR SHALL ALSO
BE HANDLED BY DUCT(S)
SEALED TO THE AIR HANDLER
CASING AND TERMINATING
OUTSIDE THE SPACE
CONTAINING THE AIR HANDLER.
INSTALLATION MUST COMPLY
WITH ALL INSTALLATION
INSTRUCTIONS INCLUDING:
• AIR HANDLER OPERATING
UNDER THERMOSTATIC
CONTROL;
• RETURN AIR DUCT SEALED TO
THE AIR HANDLER;
• AIR FILTERS IN PLACE;
• RETURN AIR TEMPERATURE
MAINTAINED BETWEEN 55°F
(13°C) AND 80°F (27°C); AND
• CLEAN AIR HANDLER, DUCT
WORK AND COMPONENTS
UPON SUBSTANTIAL
COMPLETION OF THE
CONSTRUCTION PROCESS,
AND VERIFY AIR HANDLER
OPERATING CONDITIONS
INCLUDING FLOW RATE AND
TEMPERATURE RISE,
ACCORDING TO THE
INSTRUCTIONS.

WARNING
HORIZONTAL UNITS MUST BE
CONFIGURED FOR RIGHT HAND
AIR SUPPLY OR LEFT HAND AIR
SUPPLY. HORIZONTAL DRAIN
PAN MUST BE LOCATED UNDER
INDOOR COIL. FAILURE TO USE
THE DRAIN PAN CAN RESULT IN
PROPERTY DAMAGE.

CAUTION
WHEN USED IN COOLING
APPLICATIONS, EXCESSIVE
SWEATING MAY OCCUR WHEN
UNIT IS INSTALLED IN AN
UNCONDITIONED SPACE. THIS
CAN RESULT IN PROPERTY
DAMAGE.
