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 D’ÉLECTROCUTION, D’INCENDIE
OU D’EXPLOSION
Si les consignes de sécurité ne sont pas suivies
à la lettre, cela peut entraîner la mort, de graves
blessures, un fonctionnement dangereux ou
des dommages matériels.
Un entretien inadéquat peut entraîner la mort,
de graves blessures, un fonctionnement
dangereux ou des dommages matériels.
• Avant de faire l’entretien de l’appareil de
chauffage, le débrancher de l’alimentation
électrique.
• Avant l’entretien des commandes, étiqueter
tous les fils avant de les déconnecter.
Rebrancher correctement les fils.
• Vérifier que l’appareil fonctionne correctement
après 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.
• Horizontal Mounted Units Only - 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.
Particular attention must be given to identify deterioration
from corrosion or other sources.
