New or Replacement Line Set

REFRIGERANT LINE SET

This section provides information on installation or replacement of existing line set. If new or replacement line set is not being installed then proceed to Brazing Connections on page 12.

IMPORTANT

Lennox highly recommends changing line set when converting the existing system from HCFC−22 to HFC−410A. If that is not possible and the line set is the proper size as reference in table 2, use the procedure outlined under Flushing the System on page 13.

If refrigerant lines are routed through a wall, then seal and isolate the opening so vibration is not transmitted to the building. Pay close attention to line set isolation during installation of any HVAC system. When properly isolated from building structures (walls, ceilings. floors), the refrigerant lines will not create unnecessary vibration and subsequent sounds. See figure 6 for recommended installation practices. Also, consider the following when placing and installing a high−efficiency outdoor unit.

Liquid lines that meter the refrigerant, such as RFC1 liquid lines, must not be used in this application. Existing line set of proper size as listed in table 2 may be reused. If system was previously charged with HCFC−22 refrigerant, then existing line set must be flushed (see Flushing Line Set and Indoor Coil on page15).

Field refrigerant piping consists of liquid and vapor lines from the outdoor unit to the indoor unit coil (braze connections). Use Lennox L15 (sweat, non−flare) series line set, or field−fabricated refrigerant line sizes as listed in table 2.

NOTE When installing refrigerant lines longer than 50 feet, see the Lennox Refrigerant Piping Design and Fabrication Guidelines, CORP. 9351−L9, or contact Lennox Technical Support Product Applications for assistance.

To obtain the correct information from Lennox, be sure to communicate the following information:

SModel (XC16) and size of unit (e.g. −036).

SLine set diameters for the unit being installed as listed in table 2 and total length of installation.

SNumber of elbows vertical rise or drop in the piping.

The compressor is charged with sufficient Polyol ester oil for line set lengths up to 50 feet. Recommend adding oil to system based on the amount of refrigerant charge in the system. No need to add oil in system with 20 pounds of refrigerant or less. For systems over 20 pounds − add one ounce of every five pounds of refrigerant.

Recommended topping−off POE oils are Mobil EAL ARCTIC 22 CC or ICI EMKARATEt RL32CF.

IMPORTANT

Mineral oils are not compatible with HFC−410A. If oil must be added, it must be a Polyol Ester oil.

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.
