WRAP SERVICE VALVES

To help protect service valve seals during brazing, wrap water saturated cloths around service valve bodies and copper tube stubs. Use additional water saturated cloths underneath the valve body to protect the base paint.

FLOW NITROGEN

Flow regulated nitrogen (at 1 to 2 psig) through the refrigeration gauge set into the valve stem port connection on the liquid service valve and out of the suction / vapor valve stem port. See steps 3A, 3B and 3C on manifold gauge set connections

6BRAZE LINE SET

Wrap both service valves with water saturated cloths as illustrated here and as mentioned in step 4, before brazing to line set. Water saturated cloths must remain water saturated throughout the brazing and cool−down process.

IMPORTANT Allow braze joint to cool. Apply additional water saturated cloths to help cool brazed joint. Do not remove water saturated cloths until piping has cooled. Temperatures above 250ºF will damage valve seals.

WARNING

1.FIRE, PERSONAL INJURY, OR PROPERTY

DAMAGE may result if you do not wrap a water saturated cloth around both liquid and suction line service valve bodies and copper tube stub while brazing in the line set! The braze, when complete, must be quenched with water to absorb any residual heat.

2. Do not open service valves until refrigerant lines and indoor coil have been leak−tested and evacuated. Refer to procedures provided in this supplement.

7PREPARATION FOR NEXT STEP

After all connections have been brazed, disconnect manifold gauge set from service ports. Apply additional water saturated cloths to both services valves to cool piping. Once piping is cool, remove all water saturated cloths. Refer to the unit installation instructions for the next step in preparing the unit.

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.
