The LG AXSVA4 model, and related AXSVA3 sleeve, are designed for through-the-wall air conditioner installations in pre-cast concrete or masonry walls. These sleeves provide structural support for the air conditioner unit, insulation, and protection for the outer coils. Installation requires secure fastening within the wall and attention to electrical receptacle placement and proximity to heating sources. This document details the installation process based on available manufacturer instructions.
Sleeve Specifications and Components
The LG AXSVA4 through-the-wall air conditioner sleeve has specific dimensions crucial for proper installation. Outside dimensions are 15-17/32 inches in height, 25-7/8 inches in width, and 16-23/32 inches in depth. Inside dimensions measure 14-7/8 inches in height, 25-5/16 inches in width, and 15-5/16 inches in depth. The sleeve’s weight is 30.86 pounds, and it is colored white.
The sleeve assembly includes the following components, as detailed in the documentation: a TTW sleeve with an expanded grille (model AXSVA3), two weather panels (front and back), one expanded aluminum rear grille, eight supporter pieces, and fourteen washer screws.
Preparing the Wall Opening
Prior to installing the sleeve, the existing wall opening must be prepared. This involves removing any existing air conditioner and its sleeve, if present. The documentation emphasizes the importance of securely fastening the new wall sleeve into the wall opening. The installation process differs slightly depending on whether the sleeve is being installed into pre-cast concrete or masonry. In either case, a lintel (purchased locally) and mortar are required for a secure installation.
The documentation provides dimensional guidance for the wall opening. The sleeve requires a masonry or frame opening with specific measurements, as illustrated in the provided diagrams. The diagrams show dimensions of 25-7/8" (656mm) for the width, 16-23/32" (425mm) for the depth, and 15-17/32" (394mm) for the height. A minimum 2" gap is required below the sleeve.
Installation Procedure
The installation procedure involves several key steps. First, the old air conditioner and sleeve must be removed. Next, the new wall sleeve is prepared for installation into the wall opening. The documentation stresses that the wall sleeve must be fastened securely before the air conditioner unit is installed.
The documentation highlights the importance of keeping the cover panels for later use, as they provide protection from inclement weather. Additionally, the electrical wall receptacle should be positioned within 20 inches of the left side or 45 inches of the right side of the wall opening.
To prevent damage to the air conditioner’s plastic front, the sleeve should be installed at least 4 inches away from any heating sources, such as baseboard heaters or radiators. After the sleeve is installed, the perimeter around the exterior wall opening and sleeve should be caulked using a high-quality caulking material to prevent drafts and moisture intrusion.
Electrical Receptacle Considerations
Proper electrical connection is critical for the operation of the through-the-wall air conditioner. The documentation specifies that the electrical wall receptacle must be located within a defined range of the wall opening. Specifically, the receptacle should be installed within 20 inches of the left side or 45 inches of the right side of the wall opening. This ensures convenient and safe access for powering the air conditioner unit.
Preventing Distortion and Ensuring Weather Protection
The documentation addresses two specific concerns during installation: preventing distortion of the air conditioner’s plastic front and ensuring adequate weather protection. To avoid distortion, the sleeve must be installed at least 4 inches away from any heating sources. This prevents heat from warping or damaging the plastic components.
Weather protection is achieved by utilizing the cover panels that come with the sleeve. These panels should be retained and used to protect the unit from rain and wind when it is not in use. Additionally, caulking the perimeter of the sleeve after installation further enhances weather resistance.
Sleeve Hardware and Assembly
The sleeve assembly utilizes specific hardware components. These include washer screws, used for securing the various parts of the sleeve together. The documentation lists the quantity of each component: 14 washer screws are provided. The expanded aluminum rear grille is also a key component, providing protection for the outer coils of the air conditioner. The supporter pieces contribute to the overall structural integrity of the sleeve installation.
Conclusion
The LG AXSVA4 through-the-wall air conditioner sleeve is designed for secure and reliable installation in pre-cast concrete or masonry walls. Proper installation requires careful attention to dimensions, secure fastening, electrical receptacle placement, and weather protection. Following the provided instructions ensures optimal performance and longevity of the air conditioning system. The sleeve’s components, including the grille and weather panels, contribute to the unit’s overall functionality and protection.
