Us this method if the existing outdoor unit is not equipped with shut−off valves, or if the unit is not operational and you plan to use the existing HCFC−22 to flush the system.

Remove all HCFC−22 refrigerant from the existing system. Check gauges after shutdown to confirm that the entire system is completely void of refrigerant.

METHOD 2:

Use this method if the existing outdoor unit is equipped with manual shut−off valves, and you plan to use new HCFC−22 refrigerant to flush the system.

The following devices could prevent full system charge recovery into the outdoor unit:

SOutdoor unit’s high or low−pressure switches (if applicable) when tripped can cycle the compressor OFF.

SCompressor can stop pumping due to tripped internal pressure relief valve.

SCompressor has internal vacuum protection that is designed to unload the scrolls (compressor stops pumping) when the pressure ratio meets a certain value or when the suction pressure is as high as 20 psig. (Compressor suction pressures should never be allowed to go into a vacuum. Prolonged operation at low suction pressures will result in overheating of the scrolls and permanent damage to the scroll tips, drive bearings and internal seals.)

Once the compressor can not pump down to a lower pressure due to one of the above system conditions, shut off the vapor valve. Turn OFF the main power to unit and use a recovery machine to recover any refrigerant left in the indoor coil and line set.

Perform the following task:

AStart the existing HCFC−22 system in the cooling mode and close the liquid line valve.

BUse the compressor to pump as much of the existing HCFC−22 refrigerant into the outdoor unit until the outdoor system is full. Turn the outdoor unit main power OFF and use a recovery machine to remove the remaining refrigerant from the system.

NOTE

CWhen the low side system pressures reach 0 psig, close the vapor line valve.

DCheck gauges after shutdown to confirm that the valves are not allowing refrigerant to flow back into the low side of the system.

Elite Series X16 Air Conditioner Units, 506637-01 specifications

The Lenox 506637-01, Elite Series X16 Air Conditioner is a top-tier cooling solution that stands out in the residential HVAC market. Known for its impressive energy efficiency and advanced features, this unit is designed to provide homeowners with exceptional comfort while also keeping energy bills in check.

One of the main highlights of the Elite Series X16 is its SEER rating, which stands at an impressive 16. This makes it one of the most energy-efficient air conditioning systems available, ensuring that it operates effectively without consuming excessive power. By converting less energy into cooling, homeowners can enjoy lower utility bills and a reduced carbon footprint.

The X16 model features a two-stage cooling system, which allows for better humidity control and more even temperature distribution throughout the home. Unlike standard single-stage units that operate at full capacity at all times, the two-stage system enables the air conditioner to run at a lower, more efficient speed for the majority of its operation, only ramping up when additional cooling is needed. This not only enhances comfort but also extends the lifespan of the unit.

Incorporating advanced technology, the Elite Series X16 utilizes a high-efficiency scroll compressor and innovative airflow design. This results in quieter operation, providing a peaceful indoor environment. The noise levels are minimal, making it suitable for nighttime use or for homes where noise might be a concern.

The air conditioner is built with durability in mind, featuring a robust cabinet that protects against the elements and potential wear and tear over time. Its louvered design provides additional protection for critical components, ensuring longevity and consistent performance.

Furthermore, the X16 is compatible with smart thermostats and home automation systems, allowing homeowners to optimize their cooling schedules remotely. This connectivity helps users make informed decisions about energy usage, further enhancing efficiency while providing ultimate control over home comfort.

In summary, the Lenox 506637-01, Elite Series X16 Air Conditioner provides an excellent blend of energy efficiency, advanced technology, and a focus on comfort and durability. With its two-stage cooling system, high SEER rating, and quiet operation, it is an ideal choice for those seeking a reliable, high-performance cooling solution for their homes.
