Over-Temperature Limit Control - The over-temperature
limit control prevents the air temperature leaving the unit
from exceeding the maximum outlet air temperature.
If the limit opens, the integrated control diagnostic will
flash one time. The circulating air blower and combustion
blower will continue to operate if the over-temperature
limit control opens.
EQUIPMENT MAINTENANCE
WARNING:
ELECTRICAL SHOCK, FIRE OR
EXPLOSION HAZARD
Failure to follow safety warnings exactly could
result in serious injury or property damage.
Improper servicing could result in dangerous
operation, serious injury, death or property
damage.
• Before servicing, disconnect all electrical
power to furnace.
• When servicing controls, label all wires prior
to disconnecting. Reconnect wires correctly.
• Verify proper operation after servicing."
AVERTISSEMENT:
RISQUE DE CHOC ÉLECTRIQUE,
D'INCENDIE OU D'EXPLOSION
Le non-respect des avertissements de
sécurité pourrait entraîner un fonctionnement
dangereux de l'appareil, des blessures graves,
la mort ou des dommages matériels.
Un entretein incorrect pourrait entraîner un
fonctionnement dangereux de l'appareil, des
blessures graves, la mort ou des dommages
matériels
• Couper toute alimentation électrique au
générateur d'air chaud avant de prodéder
aux travaux d'entretein.
• Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher.
S'assurer de les raccorder correctement.
• S'assurer que l'appareil fonctionne
adéquatement aprés l'entretien.
CAUTION:
Use care when removing parts from this unit.
Personal injury can result from sharp metal
edges present in all equipment of sheet metal
construction.
Proper maintenance is important to achieve optimum
performance from the system. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your
local dealer about the availability of maintenance contracts.
Routine maintenance should include the following:
CAUTION:
The unit should never be operated without a
filter in the return air system.Replace disposable
filters with the same type and size.
• Inspect, clean or replace air filters at the beginning of
each heating and cooling season, or more frequently
if required.
• Inspect the evaporator condensate drain and outdoor coil
at the beginning of each cooling season. Remove any
debris. Clean the outdoor coil and louvers as necessary
using a mild detergent and water. Rinse thoroughly with
water.
• Inspect the electrical connections for tightness at the
beginning of each heating and cooling season.
• The blower compartment should be cleaned monthly
during the heating and cooling seasons to remove any dirt
and lint that may have accumulated in the compartment
or on the blower and motor. Buildup of dirt and lint on
the blower and motor can create excessive loads on
the motor resulting in higher than normal operating
temperatures and possible shortened service life.
• The motors for the circulating air blower, outdoor fan,
and combustion blower are pre-lubricated at the factory.
No further oiling is required for the life of this product.
• Inspect and clean the screen of the vent cover assembly
at the beginning of each heating and cooling season.
• Inspect the heat exchanger condensate drain at the
beginning of each heating season.
• Inspect condensate disposal pit or trench to ensure
ground is still higher than surrounding area to shed rain
and melting snow away from pit or trench.
Heat Exchanger & Burner Maintenance
WARNING:
Holes in the heat exchanger can cause products
of combustion to enter the home.Replace the heat
exchanger if leaks are found. Failure to prevent
products of combustion from being circulated
into the living space can create potentially
hazardous conditions including carbon monoxide
poisoning that could result in personal injury or
death.
• Maintain heat exchanger and burners. The furnace
should operate for many years without excessive
scale buildup in the heat exchanger, however, the heat
exchanger, the vent system, and the burners should
be inspected and cleaned (if required) by a qualified
serviceman annually to ensure continued safe operation.
