at the indoor unit (installed internal or external to the cabinet) or behind a return air grille in the wall or ceiling. Check the filter monthly and clean or replace it as needed.

2.Disposable Filter Disposable filters should be replaced with a filter of the same type and size.

NOTE If you are unsure about the filter required for your system, call your Lennox dealer for assistance.

3.Reusable Filter Many indoor units are equipped with reusable foam filters. Clean foam filters with a mild soap and water solution; rinse thoroughly; allow filter to dry completely before returning it to the unit or grille.

NOTE The filter and all access panels must be in place any time the unit is in operation.

4.Indoor Unit The indoor unit’s evaporator coil is equipped with a drain pan to collect condensate formed as your system removes humidity from the inside air. Have your dealer show you the location of the drain line and how to check for obstructions. (This would also apply to an auxiliary drain, if installed.)

Thermostat Operation

See the thermostat homeowner manual for instructions on how to operate your thermostat.

Preservice Check

If your system fails to operate, check the following before calling for service:

SVerify room thermostat settings are correct.

SVerify that all electrical disconnect switches are ON.

SCheck for any blown fuses or tripped circuit breakers.

SVerify unit access panels are in place.

SVerify air filter is clean.

SIf service is needed, locate and write down the unit model number and have it handy before calling.

Elite Series, XC14 specifications

The Lenox Elite Series XC14 is a remarkable tool designed for superior cutting performance in various applications. This saw blade stands out due to its innovative technologies and features, which cater to the needs of professionals in woodworking, metalworking, and general cutting tasks.

One of the key features of the XC14 is its carbide-tipped teeth. These teeth are engineered for longevity and efficiency, allowing for extended use without performance degradation. The unique geometry of the teeth enhances cutting speed while minimizing resistance, making it ideal for a range of materials including hardwoods, softwoods, and metals.

The blade’s construction is another significant aspect of its design. Made from high-quality steel, the XC14 ensures durability and resistance to bending or warping under stress. This robust construction contributes to the blade's overall stability, resulting in smoother cuts and reduced vibration during operation.

Another noteworthy technology embedded in the XC14 is its advanced tooth design. The combination of alternate top bevel (ATB) and flat (F) configurations allows for precision cutting and a cleaner finish. This feature is particularly beneficial when working on intricate projects that require a high level of accuracy.

To enhance performance further, the XC14 incorporates a unique thin kerf design. This design reduces the width of the cut, which not only conserves material but also requires less power from the saw. This energy efficiency translates to less wear on the saw, extending the lifecycle of both the blade and the tool itself.

The blade is also designed with heat dissipation in mind. Specially engineered cooling vents help in maintaining optimal temperature during operation. This technology reduces the risk of overheating, which can compromise the integrity of the blade and the quality of the cut.

Versatility is another standout feature of the Lenox Elite Series XC14. It is suitable for table saws, miter saws, and portable saws, making it a valuable tool for professionals and DIY enthusiasts alike. Whether tackling large construction projects, meticulous cabinetry, or small home repairs, the XC14 adapts efficiently to diverse cutting needs.

In conclusion, the Lenox Elite Series XC14 combines advanced technologies, premium materials, and thoughtful design to deliver exceptional cutting performance. Its carbide-tipped teeth, innovative geometry, stable construction, thin kerf, heat dissipation features, and versatility make it a top choice for those seeking reliable and efficient cutting solutions in various applications.
