Servicing Units Delivered Void of Charge

If the outdoor unit is void of refrigerant, clean the system using the procedure described below.

1.Leak check system using procedure outlined on page 17.

2.Evacuate the system using procedure outlined on page 18.

3.Use nitrogen to break the vacuum and install a new filter drier in the system.

4.Evacuate the system again using procedure outlined on page 18.

5.Weigh in refrigerant using procedure outlined in figure 21.

6.Monitor the system to determine the amount of moisture remaining in the oil. It may be necessary to replace the filter drier several times to achieve the required dryness level. If system dryness is not verified, the compressor will fail in the future.

Unit Start−Up

IMPORTANT

If unit is equipped with a crankcase heater, it should be energized 24 hours before unit start−up to prevent compressor damage as a result of slugging.

1.Rotate fan to check for binding.

2.Inspect all factory− and field−installed wiring for loose connections.

3.After evacuation is complete, open both the liquid and vapor line service valves to release the refrigerant charge contained in outdoor unit into the system.

4.Replace the stem caps and tighten to the value listed in table 1.

5.Check voltage supply at the disconnect switch. The voltage must be within the range listed on the unit’s nameplate. If not, do not start the equipment until you have consulted with the power company and the voltage condition has been corrected.

6.Set the thermostat for a cooling demand. Turn on power to the indoor indoor unit and close the outdoor unit disconnect switch to start the unit.

7.Recheck voltage while the unit is running. Power must be within range shown on the nameplate.

8.Check system for sufficient refrigerant by using the procedures listed under System Charge.

System Refrigerant

This section outlines procedures for:

1.Connecting gauge set for testing and charging;

2.Checking and adjusting indoor airflow;

3.Adding or removing refrigerant.

XC14 SERIES

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.
