EVACUATE THE SYSTEM

RECOMMEND

A Open both manifold valves and start the vacuum pump.

MINIMUM 3/8" HOSE

 

 

2 B Evacuate the line set and indoor unit to an absolute pressure of 23,000 microns (29.01 inches of mercury).

indicates a relatively large leak. If this occurs, repeat the leak testing procedure.

 

 

 

NOTE

absolute pressure means the total actual pressure within a given volume or system, above the absolute zero of

pressure. Absolute pressure in a vacuum is equal to atmospheric pressure minus vacuum pressure.

CWhen the absolute pressure reaches 23,000 microns (29.01 inches of mercury), perform the following:

Close manifold gauge valves

Close valve on vacuum pump

Turn off vacuum pump

Disconnect the manifold gauge center port hose from vacuum pump

Attach manifold center port hose to a dry nitrogen cylinder with pressure regulator set to 150 psig (1034 kPa) and purge the hose.

Open manifold gauge valves to break the vacuum in the line set and indoor unit.

SClose manifold gauge valves.

DShut off the dry nitrogen cylinder and remove the manifold gauge hose from the cylinder. Open the manifold gauge valves to release the dry nitrogen from the line set and indoor unit.

EReconnect the manifold gauge to the vacuum pump, turn the pump on, and continue to evacuate the line set and indoor unit until the absolute pressure does not rise above 500 microns (29.9 inches of mercury) within a 20−minute period after shutting off the vacuum pump and closing the manifold gauge valves.

FWhen the absolute pressure requirement above has been met, disconnect the manifold hose from the vacuum pump and connect it to an upright cylinder of HFC−410A refrigerant. Open the manifold gauge valve 1 to 2 psig in order to release the vacuum in the line set and indoor unit.

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.
