Proper Maintenance – Air Handlers
To prevent injury or death, or property damage, read and follow all instructions and warnings, including labels shipped with or attached to the unit before operating your new air conditioning system.
WARNING: Improper installation, adjustment, alteration, service maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer or service agency for information or assistance. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product.
WARNING: Disconnect all electric power to the indoor air handler or furnace before removing access panels to perform any maintenance. Disconnect power to both the indoor and outdoor units.
A clean filter saves money. Help ensure top efficiency by cleaning the filter regularly. When the unit circulates and filters the air in your home, dust and dirt particles collect on the filter. Excessive buildup forces the system to run longer to maintain your set temperature, increasing energy costs.
CAUTION: Although special care has been taken to minimize sharp edges in the construction of the unit, be extremely careful when handling parts or reaching into the unit.
Clean or replace your filter at least once a month, or twice a month when the system is running more often.
If you have a semi-permanent filter, you can take the filter out of the frame and vacuum it. If disposable filters are used, they must be replaced every month with the same size as originally supplied. Both methods are quick and easy. When replacing filters, always use the same size and type that was originally supplied. Filters are available from your dealer.
Energy Saving Tips: Don't waste money heating and cooling when you don't need to. When away from home for a few days or when outdoor temperatures are moderate, lower the thermostat to 55°F in winter or raise it to 85°F in summer. Continuous fan mode during cooling operation may not be appropriate in humid climates; if indoor air exceeds 60% relative humidity, use the fan in AUTO mode.
CAUTION: If heating system is not operational during cold weather months, take provisions to prevent freeze-up of all water pipes and water receptacles, especially during times of vacancy.
Never stop the system by shutting off the main power. If the main power is disconnected for more than three hours, turn off the thermostat, wait at least three more hours after power restoration, then turn the thermostat back on to prevent system damage.
How to remove the filter from your Air Handler:
Ask your dealer where the filter is located. It may be behind the bottom panel, at the top, bottom, or side, or there may be two filters. Removing a filter is easy. Insert the clean filter with the arrows pointing in the direction of airflow. Your installing dealer is your best source of filter and maintenance information.
Locate access door marked "FILTER" and lift up the open side of the levers.
Slide dirty filter out, replace with a new filter making sure the arrows printed on it are pointing in the direction of airflow.
Hold the "FILTER" door firmly in place and snap the levers down (closed).
Cut operating costs by keeping snow, ice, and debris clear of your outdoor heat pump unit. Efficient operation requires free airflow over the coils. Do not stack anything against the side of the outdoor unit or drape over it.
NOTE: Condensation may occur on the surface of the air handler when installed in an unconditioned location.

Proper Maintenance – Gas Furnaces
Air Filters
Clean the filter once a month for optimum performance. A monthly visual inspection of the furnace is also recommended (See General Inspection on page 9, number 1). NOTE: Filters are NOT included with all Furnaces; however, the Furnace should never be run without a filter.
A clean filter saves money. Excessive filter accumulation can block airflow, forcing the unit to work harder and use more energy.
Never operate your unit for either heating or cooling with filters removed.
Help ensure top efficiency by cleaning the filter once a month, or twice a month during seasons when the unit runs more often. You can clean the filter with a vacuum or wash it with a household detergent. NOTE: Not all aftermarket filters can be washed with a household detergent; see manufacturer's instructions.
When replacing filters, always use a high velocity type of the same size as originally supplied. Filters are available from your dealer. Disposable filters must also be of the same high velocity type and size.
How to remove the filter from your Gas Furnace
ELECTRIC SHOCK HAZARD: Disconnect power to the unit before removing the blower door. Failure to follow this warning could result in property damage, personal injury, or death.
Upflow furnaces use a high velocity type air filter located within the blower compartment, in either a BOTTOM or SIDE (left or right) return air inlet. The filter may be secured with retaining brackets or a filter rack.
To clean or replace filters, remove the blower access door, slide the filter from the rack or remove it from retaining brackets. After cleaning, replace the filter securely, ensuring brackets (if present) hold it properly or it is securely slid into the rack.
Filter Locations and Types:
- Upflow Bottom Return: Diagram shows a filter behind a removable access door, secured by retaining brackets. Air flows from bottom to top. For bottom return inlets, a 17" x 25" x 1" filter is used in the 17-1/2" wide furnace; a 20" x 25" x 1" filter in the 21" wide models; and a 24" x 25" x 1" filter in the 24-1/2" wide cabinet.
- Upflow Side Return: Diagram shows a filter behind a removable access door, secured by retaining brackets. Air flows from side to top. For vertical upflow units with left or right return air inlets, the factory-supplied filter may need to be trimmed to 17" x 25" x 1" for both the 21" and 24-1/2" wide furnaces.
- Upflow/Horizontal Furnace Filters: When installed horizontally, these furnaces require a horizontal filter kit. Filters may be located remote to the furnace or in the return air duct near the furnace. For horizontal return air applications, two filters (e.g., 16" x 20" x 1") are used in the 17-1/2", 21", and 24-1/2" wide furnace cabinets. To replace, remove the access door, lift the filter from the lower bracket, shift it to the side to free the top filter, and slide filters out. Replace in reverse order, ensuring filters are secured.
- Downflow Filter: Diagram shows a filter located in the return air duct.
- Downflow/Horizontal With Filter Kit: Diagram shows a filter kit installed in the return air duct. For downflow/horizontal furnaces, two 14" x 20" x 1" filters are used in 17-1/2" wide cabinets, or two 16" x 20" x 1" filters in 21" and 24-1/2" wide cabinets.
Air filters may also be located outside the furnace using a remote filter grille (in a hallway, wall, or ceiling). Check with your dealer for exact location and changing method.
Downflow/Horizontal furnaces may be supplied with 2 standard size permanent type air filters located remote to the furnace or in the return air duct. Check with your dealer.

CARBON MONOXOXIDE POISONING HAZARD: Do not attempt to change the venting system. Failure to follow installation and operation instructions for the venting system could result in carbon monoxide poisoning or death.
NOTE: Improperly sized vents can cause condensate formation, combustion gas leakage and spillage, and an inoperable furnace.
A furnace is a complex system requiring professional maintenance and repair. Attempts at "do-it-yourself" repairs on an in-warranty unit may void your warranty.
Other than simple maintenance, do not attempt adjustments. Your dealer can answer questions or resolve problems. A periodic inspection by a qualified service agency at the start of each heating season is recommended.
In the event of electrical, fuel, or mechanical failures, immediately turn the gas supply off at the manual gas valve before turning off electrical power. Contact a qualified service agency.
Keep your furnace looking like new by cleaning the enamel finish with ordinary soap and water. For stubborn grease spots, use a household detergent. Lacquer thinner or other synthetic solvents may damage the finish.
Regular Dealer Maintenance
For regular dealer maintenance, please refer to www.acca.org/industry/quality.
To ensure proper operation, the recommended dealer inspection is once a year, before the heating season, performed by a qualified service professional. The homeowner should perform the visual inspection in step 1 monthly when cleaning the furnace filter.
Unless it is an emergency, never stop the heating system by shutting off the main power. If the main power is disconnected for more than three hours, turn off the thermostat, wait at least three more hours after power restoration, then turn the thermostat back on to prevent system damage.
HAZARDOUS GASES: Exposure to fuel substances or by-products of incomplete fuel combustion is believed by the State of California to cause cancer, birth defects, or other reproductive harm.
HAZARDOUS GASES: The unit is equipped with a blower door switch that cuts power to the blower and gas valve when the door is removed. Do not alter the unit to allow operation with the blower door removed. Operation with doors removed or ajar can permit the escape of dangerous fumes. All panels must be securely closed at all times.
EXPLOSION HAZARD: In the event of electrical, fuel, or mechanical failures, SHUT off the gas supply at the manual gas SHUT OFF valve before turning off electrical power. Contact a servicer.
Do NOT touch igniter. It is extremely hot.
EXPLOSION HAZARD: Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the furnace before shutting off the electrical supply.
Maintenance Steps (Performed Annually by Servicer):
- GENERAL INSPECTION: Examine furnace installation for: clear flue product carrying areas (chimney, vent connector); proper vent connector slope and condition; sound, sealed return air duct connection; sound physical support for the furnace; no obvious signs of deterioration; proper burner flame adjustment (no erratic flames); clear fresh air inlet and vent (at least 12 inches above expected snow level). Contact your service agent if uncomfortable with inspections.
- BLOWERS: Blower motor bearings are factory lubricated and typically do not require servicing. Annual cleaning of the blower wheel and housing is recommended for maximum air output and must be performed by a qualified servicer.
- IGNITER: This unit has a special hot surface direct ignition device that automatically lights burners. It is fragile and should be handled with care.
- BURNER: Gas burners do not normally require scheduled servicing, but foreign material accumulation may cause a yellowing flame or delayed ignition, indicating a service call is required. Burners must be cleaned annually using brushes and vacuum cleaner. Turn off gas and electric power supply. Remove top burner bracket and lift burner from orifice. Be careful not to break the igniter. Reassemble parts in reverse order. For LP units, light yellow tipping of the outer mantle is normal; inner mantle should be bright blue. Natural gas units should not have yellow-tipped flames. Variations in BTU content and altitude may require shorter service intervals for LP units.
- HEAT EXCHANGER/FLUE PIPE: Inspect for signs of corrosion and/or deterioration at the beginning of each heating season. Clean annually for best operation.
- CIRCUIT PROTECTION: If blower or gas valve fails, check circuit breaker or fuses. Replace fuse or reset circuit breaker.
- OPERATION: Do not operate the furnace in a corrosive atmosphere. Avoid paint solvents, cleaning chemicals, spray propellants, and bleaches near the furnace.
- CONDENSATE DRAINS: If a cooling coil is installed, check and clean condensate drains periodically to ensure free drainage from the coil and drain pan outlet. Furnace drains should also be checked and cleaned at the start of each heating season.
- AIR CIRCULATION: For increased comfort, the blower can operate continuously for heating and cooling, providing constantly filtered air and more even temperatures. Set the comfort control fan selector to "ON." Continuous fan mode during cooling may not be appropriate in humid climates; if indoor air exceeds 60% relative humidity, use "AUTO" mode.
