Brazing Connections

Use the procedures outline in figures 8 and 9 for brazing line set connections to service valves.

WARNING

Polyol Ester (POE) oils used with HFC−410A refrigerant absorb moisture very quickly. It is very important that the refrigerant system be kept closed as much as possible. DO NOT remove line set caps or service valve stub caps until you are ready to make connections.

WARNING

Danger of fire. Bleeding the refrigerant charge from only the high side may result in pressurization of the low side shell and suction tubing. Application of a brazing torch to a pressurized system may result in ignition of the refrigerant and oil mixture − Check the high and low pressures before applying heat.

WARNING

When using a high pressure gas such as dry nitrogen to pressurize a refrigeration or air conditioning system, use a regulator that can control the pressure down to 1 or 2 psig (6.9 to 13.8 kPa).

CAUTION

Brazing alloys and flux contain materials which are hazardous to your health.

Avoid breathing vapors or fumes from brazing operations. Perform operations only in well−ventilated areas.

Wear gloves and protective goggles or face shield to protect against burns.

Wash hands with soap and water after handling brazing alloys and flux.

IMPORTANT

Connect gauge set low pressure side to vapor line service valve and repeat procedure starting at paragraph 4 for brazing the liquid line to service port valve.

IMPORTANT

Allow braze joint to cool before removing the wet rag from the service valve. Temperatures above 250ºF can damage valve seals.

IMPORTANT

Use silver alloy brazing rods with 5% minimum silver alloy for copper−to−copper brazing. Use 45% minimum alloy for copper−to−brass and copper−to−steel brazing.

WARNING

Fire, Explosion and Personal Safety

Hazard.

Failure to follow this warning could result in damage, personal injury or death.

Never use oxygen to pressurize or purge refrigeration lines. Oxygen, when exposed to a spark or open flame, can cause fire and/or an ex- plosion, that could result in property damage, personal injury or death.

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.
