If refrigerant is added or removed, retest to confirm that unit is properly charged.

1.Connect gauge set as illustrated in figure 15.

2.Confirm proper airflow across coil using figure 17.

3.Compare unit pressures with table 4, Normal Operating Pressures.

4.Set thermostat to call for heat (must have a cooling load between 70-80ºF (21−26ºC).

5.When heat demand is satisfied, set thermostat to call for cooling.

6.Allow temperatures and pressures to stabilize.

7.Record outdoor ambient temperature: AMBº =_________

8.Record liquid line temperature: LIQº = __________

9.Subtract to determine approach (APPº): LIQº_____ − AMBº _____ = APPº_____

10.Compare results with table below.

APPº (Approach) Values(F:+/−1.0° [C: +/−0.6°])

If value is greater than shown (high approach), add refrigerant; if less than shown (liquid temperature too close to ambient temperature, low approach), remove refrigerant.

C SUBCOOLING TXV

BLOCK OUTDOOR COIL: [sometimes necessary with lower temperatures] Use cardboard or plastic sheet to restrict the airflow through the outdoor coil to achieve pressures from 325−375 psig (2240−2585 kPa). Higher pressures are needed to check charge. Block equal sections of air intake panels and move coverings sideways until the liquid pressure is in the above noted ranges.

1.Connect gauge set as illustrated in figure 15.

2.Confirm proper airflow across coil using figure 17.

3.Compare unit pressures with table 4, Normal Operating Pressures.

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.
