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.
