APPLICATION GUIDELINES “Equipment Selection Procedure” on page 48 “Building Ventilation Design Guide” on page 49 “Placement Considerations” on page 51
EQUIPMENT SELECTION PROCEDURE Cooling/Heating Correction Factors Single Zone Wall Mounted Art Cool™ Premier Engineering Manual For Single Zone Art Cool Premier systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction factors as shown in the table below.
BUILDING VENTILATION DESIGN GUIDE Building Ventilation Design Guide ASHRAE 62.1 and local codes specify the minimum volume of outdoor air that must be provided to an occupied space. Outdoor air is required to minimize adverse health effects, and it provides acceptable indoor air quality for building occupants. The three methods of accomplishing this with single zone systems are summarized here.
BUILDING VENTILATION DESIGN GUIDE Method 2: Unconditioned Outdoor Air (Non-Ducted, Natural Ventilation) Natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits. The open area of a window or the free area of a louver must meet the minimum percentage of the net occupied floor area. Single Zone Wall Mounted Art Cool™ Premier Engineering Manual Advantages • Occupants control the volume of the ventilation air manually.
PLACEMENT CONSIDERATIONS Selecting the Best Location DANGER To avoid the possibility of fire, do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. Failure to do so will cause serious bodily injury or death. Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death.
PLACEMENT CONSIDERATIONS Indoor Unit Clearance/Outdoor Unit Installation Single Zone Wall Mounted Art Cool™ Premier Engineering Manual Indoor Unit Best Location Figure 11: Single Zone Indoor Unit Clearance Requirements. Follow recommended best practices when choosing an indoor location for the single zone indoor unit. • Use a metal detector to locate studs in the walls. Anchor unit following stud location, to prevent damage to the wall.
PLACEMENT CONSIDERATIONS Outdoor Unit Clearances Minimum Clearance Requirements for Single Zone Art Cool Premier Systems Proper clearance for the outdoor unit coil is critical for proper unit operation. When installing the outdoor unit, consider service, inlet and outlet and minimum allowable space requirements as illustrated in the diagrams below. Specific clearance requirements in the diagram below are for the Single Zone Wall Mounted Art Cool Premier systems.

REFRIGERANT PIPING DESIGN Design Guideline Summary/Selecting Field-Supplied Copper Tubing Device Connection Limitations Single-zone systems consist of one outdoor unit and one indoor unit. One of the most critical elements of a single zone system is the refrigerant piping. The table below lists pipe length limits that must be followed in the design of a Single Zone Wall Mounted Art Cool Premier refrigerant pipe system. Refer to the figure for maximum length and elevation of piping.

INSTALLATION & LAYOUT BEST PRACTICES Refrigerant Piping System Layout Field-Provided Isolation Ball Valves Obstacles 3X When an obstacle, such as an I-beam or concrete T, is in the path of the planned refrigerant pipe run, it is best practice to route the pipe over the obstacle. If adequate space is not available to route the insulated pipe over the obstacle, then route the pipe under the obstacle.
INSTALLATION & LAYOUT BEST PRACTICES Refrigerant Piping System Layout Pipe Sleeves at Penetrations LG requires that all pipe penetrations through walls, floors, and pipes buried underground be properly insulated and routed through an appropriate wall sleeve of sufficient size to prevent compression of refrigerant pipe insulation and free movement of the pipe within the sleeve. Underground refrigerant pipe shall be routed inside a protective sleeve to prevent insulation deterioration See figure below.
INSTALLATION & LAYOUT BEST PRACTICES Refrigerant Piping System Layout Single Zone Art Cool Premier Outdoor Unit Connections 1. Remove the tubing cover from the unit by loosening the fastening screws. 2. Align the center of the refrigerant pipe and corresponding connection. 3. Place a couple of drops of refrigerant oil on the opening rim of the flare before assembling. add any contaminants. Tighten the flare nut initially by hand. 4.
INSTALLATION & LAYOUT BEST PRACTICES Refrigerant Piping System Layout Refrigerant Piping / Brazing Practices Single Zone Wall Mounted Art Cool™ Premier Engineering Manual It is imperative to keep the piping system free of contaminants and debris such as copper burrs, slag, or carbon dust during installation. All joints are brazed in the field. Single Zone Wall Mounted Art Cool Premier Figure 27: Refrigerant Pipe Brazing.
