3FLUSHING LINE SET

The line set and indoor unit coil must be flushed with at least the same amount of clean refrigerant that previously charged the system. Check the charge in the flushing cylinder before proceeding.

ASet the recovery machine for liquid recovery and start the recovery machine. Open the gauge set valves to allow the recovery machine to pull a vacuum on the existing system line set and indoor unit coil.

BInvert the cylinder of clean HCFC−22 and open its valve to allow liquid refrigerant to flow into the system through the vapor line valve. Allow the refrigerant to pass from the cylinder and through the line set and the indoor unit coil before it enters the recovery machine.

BHCFC−22 gauge set (low side) to the liquid line valve.

CHCFC−22 gauge set center port to inlet on the recovery machine with an empty recovery tank to the gauge set.

DConnect recovery tank to recovery machines per machine instructions.

CAfter all of the liquid refrigerant has been recovered, switch the recovery machine to vapor recovery so that all of the HCFC−22 vapor is recovered. Allow the recovery machine to pull down to 0 the system.

DClose the valve on the inverted HCFC−22 drum and the gauge set valves. Pump the remaining refrigerant out of the recovery machine and turn the machine off.

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.

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.
