WINTERIZATION

[]NIT AND PROPERTY DAMAGE HAZARD

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

If the furnace is installed in an unconditioned space where the ambient temperatures may be 32 ° F (0 ° C) or lower, freeze

protection measures must be taken to prevent minor property or product damage.

Since the furnace uses a condensing heat exchanger, some water

will accumulate in the unit as a result of the heat transfer process.

Therefore, once it has been operated, it cannot be turned off and

left off for an extended period of time when temperatures will

reach 32°F (0°C) or lower unless winterized. Follow these

)rocedures to winterize your furnace:

1. Obtain propylene glycol (RV/swimming pool antifreeze or equivalent).

2. Turn off gas and electrical supplies to your furnace.

7.Pour 1 quart of anti-freeze solution into the funnel/tube.

Antifreeze should run through the inducer housing, overfill condensate trap and flow to an open drain.

8.If a condensate pump is used, check with pump

manufacturer to verify pump is safe for use with antifreeze

used. Allow pump to start and pump anti-freeze to open drain.

9.Remove funnel and tube from collector box.

10.Replace plug in collector box.

11.Remove the other plug and repeat steps 4-10.

12.Replace main door.

13.When furnace is re-started, flush condensate pump with clear water to check for proper operation before re-starting furnace.

14.Propylene glycol need not be removed before re-starting furnace.

Furnace specifications

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.
