Failureto follow this caution may result in personal injury.

Although special care has been taken to nfininfize sharp

edges, be extremely careful when handling parts or reaching

into the furnace. Wear safety glasses, gloves, and

appropriate protective clothing.

FILTERING OUT TROUBLE

NOTE: The manufacturer has specified filters which will enable

your furnace to provide lasting comfort and efficiency throughout its life. Contact your dealer to help you choose filters for your furnace that both collect dirt before it enters your furnace, as well

as provide a low resistance to circulating air. Avoid filters that report high cleaning efficiencies, but do not allow air to pass easily through them.

UNIT PERFORMANCE HAZARD

Failure to follow this caution may result in unit component damage.

Never operate your furnace without a filter in place. Doing

so may damage the furnace blower motor. An accumulation of dust and lint on internal parts of your furnace can cause a loss of efficiency.

a. Remove filter cabinet door. (See Fig. 21 and 22.)

NOTE: It may be necessary to remove one thumbscrew.

b.Slide air filter out of furnace. Keep dirty side up (if dirty) to avoid spilling dirt.

3.Inspect the filter. If torn, replace it.

NOTE: If a washable filter was supplied with the furnace and has been replaced by:

•Disposable media filter--Do not clean. If dirty, replace only with media filter having the same part number and

size. Install with airflow direction arrow pointing to- wards blower.

•Electronic Air Cleaner (EAC), refer to the EAC Owner's Manual for maintenance information.

4.If washable filter, wash filter (if dirty) in a sink, bathtub, or outside with a garden hose. Always use cold tap water. A nfild liquid detergent may be used if necessary. Spray water through filter in the opposite direction of airflow. Allow fil- ter to dry.

5.Reinstall clean air filter.

6.Turn on electrical supply to the furnace.

If your furnace air filter needs to be replaced, be sure to use a

factory-authorized filter of the same size that was originally specified. Use the filter tables and compare your furnace size with the proper filter size.

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.

Use care when cutting support rods in filters to protect against flying pieces and sharp rod ends. Wear safety glasses, gloves, and appropriate protective clothing.

A dirty filter will cause excessive stress on the furnace, heat exchanger, and blower motor, and can cause it to overheat and automatically shut down. The furnace filter should be checked every four weeks and be cleaned or replaced if necessary.

If installed with factory-specified disposable media filter, check or replace filter before each heating and cooling season. Replace disposable media filter at least once a year.

If your furnace filter needs replacing, be sure to use the same size and type of filter that was originally specified.

The air filter for the furnace may be located in an external filter cabinet attached to the side or bottom of the furnace casing. If the air filter has been installed in another location, contact your dealer for instructions. To inspect, clean and/or replace the air filter(s), follow these steps:

1.Turn off electrical supply to the furnace. See Fig. 20.

2.Remove air filter from the filter cabinet.

Carrier has long been synonymous with heating and cooling, and their range of furnaces exemplifies their commitment to innovation, efficiency, and reliability. A Carrier furnace is designed to provide comfortable warmth during the colder months while optimizing energy use, which is crucial in today’s environmentally conscious landscape.

One of the standout features of Carrier furnaces is their high-efficiency ratings. Many of their models boast an Annual Fuel Utilization Efficiency (AFUE) of up to 98%, meaning that they convert nearly all the fuel they consume into usable heat. This not only leads to lower energy bills but also reduces carbon emissions, making it an eco-friendly choice.

Carrier employs a range of advanced technologies to enhance performance. One key technology is the Infinity control system, which allows homeowners to monitor and adjust their heating settings remotely through a smartphone app. This system uses predictive algorithms to learn a homeowner's preferences, ensuring optimal comfort and efficiency.

Additionally, some Carrier furnaces utilize modulating technology. Unlike traditional furnaces that can only operate at full or partial capacity, modulating furnaces can adjust their output to match the specific heating demand of a home. This results in more even heating, reduced temperature swings, and greater energy savings.

Carrier also prioritizes quiet operation, with many of their models featuring a sound-dampening design. This ensures that the furnace runs discreetly in the background, minimizing disruptive noises while maintaining consistent comfort.

Durability and longevity are critical characteristics of Carrier furnaces. Each unit is built with high-quality materials and rigorous testing, ensuring that it can withstand the rigors of daily use in various climates. This commitment to quality means that homeowners can expect years of reliable service from their Carrier furnace.

Finally, Carrier emphasizes ease of installation and maintenance. With clear documentation and support from certified technicians, homeowners can rest assured that their furnace will be installed correctly and serviced as needed.

In summary, Carrier furnaces represent a blend of efficiency, innovation, and reliability. With high AFUE ratings, advanced technologies like the Infinity control system, modulating operation, quiet performance, and durable construction, they stand out as a top choice for homeowners seeking optimal heating solutions.
