Equipment Selection Procedure Cooling/Heating Correction Factors For Single Zone Art Cool Mirror 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 Figures 5 through 8.

Building Ventilation Design Guide Building Ventilation Design Guide Art Cool™ Mirror Wall Mounted Engineering Manual 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 (Figure 10). 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. Art Cool™ Mirror Wall Mounted Engineering Manual Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it.
Placement Considerations Indoor Unit Clearance/Outdoor Unit Installation Indoor Unit Best Location Figure 12: 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. • Clearance gap between any wall or enclosure and the left or right side of the unit must be greater than 4 inches (Figure 12).
Placement Considerations Outdoor Unit Clearances Minimum Clearance Requirements for Single-Zone Art Cool Mirror 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 Art Cool Mirror wall mount systems.

Refrigerant Piping Design Design Guideline Summary/Selecting Field-Supplied Copper Tubing Device Connection Limitations Figure 18: Art Cool Mirror System Layout. Unit = Feet 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. Table 19 lists pipe length limits that must be followed in the design of a Single Zone Art Cool Mirror refrigerant pipe system.

Installation & Layout Best Practices Refrigerant Piping System Layout Obstacles Figure 20: Installing Piping Above and Below an Obstacle. Art Cool™ Mirror Wall Mounted Engineering Manual 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 24.
Installation & Layout Best Practices Refrigerant Piping System Layout Single Zone Art Cool Mirror Outdoor Unit Connections Art Cool™ Mirror Wall Mounted Engineering Manual 1. Remove the tubing cover from the unit by loosening the fastening screws (Figures 26 and 27). 2. Align the center of the refrigerant pipe and corresponding connection as shown in Figures 29 and 30. 3. Place a couple of drops of refrigerant oil on the opening rim of the flare before assembling. Ensure you do not add any contaminants.
Installation & Layout Best Practices Refrigerant Piping System Layout Installation of Refrigerant Piping / Brazing Practices It is imperative to keep the piping system free of contaminants and debris such as copper burrs, slag, or carbon dust during installation. Refrigerant Piping System Insulation All refrigerant piping, field-provided isolation ball valves, service valves, and long radius elbows shall be completely insulated using closed cell pipe insulation.
Electrical Connections Art Cool™ Mirror Wall Mounted Engineering Manual Outdoor Electrical Connection Figure 32: LSU090HSV4/LSU120HSV4 Outdoor Unit Electrical Connection. 1. Remove the control cover from the unit by loosening the fastening screw (Figures 32 and 33). 2. Take off the caps on the conduit panel. 3. Connect both the power supply and low voltage lines to the corresponding terminals on the terminal block (see Figure 35 and Figure 36). 4. Be sure to ground the unit by following local codes. 5.
Technical Data “Mechanical Specifications” on page 54 “Acronyms” on page 55
Mechanical Specifications Single Zone Art Cool Mirror Art Cool™ Mirror Wall Mounted Engineering Manual General LG Single Zone Art Cool Mirror systems are comprised of a single outdoor unit connected to a single indoor unit with a single refrigerant circuit. These single zone systems can operate in either cooling or heating mode. These systems are capable of changing mode within a maximum time of three (3) minutes to ensure indoor temperature can be properly maintained.
