Benefits of Single Zone Wall Mount Systems • Available from 9,000 - 33,000 Btu/h • Inverter technology • All season use - heat pump models for both cooling and heating capabilities • Operating range for outdoor units of 14°F to 118°F in cooling and -4°F to 75°F in heating • Operating range for indoor units of 64°F to 90°F in cooling and 60°F to 86°F in heating • Quiet operation inside and outside • Duct-free split system Convergence of Technological Innovation with Flexibility and Style Single Zone Inverter Wall Mount Systems Single zone wall mount duct free split (DFS) systems are among the industry’s best air- conditioning units. Choosing an LG single zone wall mount product provides a system designer an edge to engineer a system with individual control, and design flexibility with advanced controls. Single zone systems are available in a nominal capacity range of 3/4 to 2-3/4 tons. These are best suited for applications with zones that require heating or cooling, such as residential, and small business office buildings. Single zone wall mount outdoor and indoor units are available in 208–230V/60Hz/1Ph. Adaptable and Flexible Single zone wall mount duct-free split (DFS) systems allow cooling or heating for the entire residence or just a single room without the need for evasive ductwork. There is no tearing down of walls or altering the homes appearance. Long refrigerant piping lengths allow for extra design flex- ibility in indoor unit installation. These units may be used for a number of residential or commercial environments such as: • Older homes • New home construction • Office buildings • Restaurants • Hospitals / Medical facilities • Schools • Nursing homes • Retail establishments • Place of worship Inverter Technology Inverter variable-speed DFS systems are measurably quieter and consume less energy than conventional air conditioners. The inverter compressor ramps up or down to match the required room capacity and maintain the comfort level. When the selected temperature is reached, the inverter compressor operates at low speed to maintain that comfort level, thereby using less energy. ARCHITECTURAL APPEAL

All rights reserved. “LG ” is a registered trademark of LG Corp. Single Zone Systems Single zone systems are equipped with inverter components that offer superior load matching and long piping installation. The product works for optimizing power consumption in residential and small office buildings. Utilizing multiple indoor wall mount units each with custom temperature controls allow for precise temperature settings in each zone of the building. Single zone sys- tems allow flexibility in interior design and complement any decor. Low Sound Levels When outdoor units operate fully loaded,they have one of the quietest sound levels in the industry. Sound is almost undetectable dur- ing off-peak operation. To promote a quiet, comfortable environment, the single zone system indoor units operate at sound levels as low as 24 dB(A) (High Efficiency Single Zone) and outdoor units as low as 45 dB(A) at full load (High Efficiency Single Zone). LG customers often ask if the outdoor unit is running after commissioning is complete. All rotating components are soft-started by the controller using digitally controlled inverters, which reduce undesirable noise caused by fans and compressors cycling on and off. Comfort Control at Its Best Tight temperature control through precise load matching maximizes the time that the indoor units remove moisture. Unlike traditional air conditioning control systems, which use thermostatic controls to maintain room temperatures, LG Single Zone Inverter controls continuously adjust the indoor unit fan speed and refrigerant flow, indirectly pro- viding lower and more consistent humidity levels in the conditioned space. The longer the indoor coil temperature is below the dew-point of the room in conjunction with air movement across the coil, the space humid- ity level will vary little, compared to technolo- gies that cycle fans and compressors on and off multiple times per hour. The outdoor unit responds by varying the compressor speed and outdoor fan motors as needed to main- tain system operating pressure. As a result, the single zone systems deliver precise space temperature control. Inverter Driven The rotary (9k-12k Btu/h systems) and twin rotary (18k-36k Btu/h systems) compressors are optimized to maximize compressor ef- ficiency, which reduces power consumption and monthly utility bills. This latest inverter technology allows single zone system out- door units to vary the compressor motor shaft speed to deliver an appropriate amount of cooling to the indoor unit. Precise refriger- ant volume delivery translates into long periods with coil surface temperatures below dew point and minimizes compressor and fan component run time. Occupants remain comfortable while utility costs are reduced. Simplified Installation Cooling and heating applications that use single zone systems simplify and reduce the mechanical and control system design time. The designer no longer has to be concerned with interconnecting chilled and condenser water piping, air-distribution duct systems,matching and selecting chillers, towers,pumps, coils, fans, air handlers, or Variable Air Volume (VAV) boxes. Operating Range Single zone systems have a nominal capac- ity range of 3/4 to 2-3/4 tons (depending on outdoor/indoor units). Operating ranges for single zone systems: Cooling: 14°F DB to 118°F DB Heating: -4°F WB to 75°F WB Installing an optional Low Ambient Wind Baffle Kit will allow operation down to 0°F in cooling mode for all single zone systems. Compact Size Single zone outdoor units have the following footprints: Single Zone High Efficiency LSU091HSV3, LSU121HSV3 (WxHxD (in)) 30 5/16 x 21 1/2 x 11 5/16.

Single Zone Extended Pipe LSU240HLV, LSU300HLV, LSU360HLV (WxHxD (in)) 34-1/4 x 31-1/2 x 12-5/8. Fin Design with Gold- Fin™ Coating All single zone outdoor units are provided with large surface coils made of copper tubes with louvered aluminum fins designed to maximize unit operating efficiency over a wide range of ambient conditions. Standard from the factory, every single zone outdoor unit coil fin surface is coated with LG’s exclusive GoldFin™ anti-corrosive coating designed to prevent natural surface corrosion of the aluminum fins. This main- tains heat transfer properties of the coil for an extended time. A hydrophilic coating is applied to the outdoor unit coil fin surface over the GoldFin coating. This coating enhances the develop- ment of heavier water droplets gathering on the fin surface. As a result, the droplets roll off the fin surfaces, delaying the point when frost forms on the coil surface during heating operation. This coating also makes it possible to easily clean the outdoor unit coil using a mild soap.

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. Although we believe that these building ventilation methods have been portrayed accurately, none of the methods have been tested, verified, or evaluated by LG Electronics, U.S.A., Inc., In all cases, the designer, installer, and contractor should understand if the suggested method is used, it is used at their own risk. LG Electronics U.S.A., Inc., takes no responsibility and offers no warranty, expressed or implied, of merchantability or fitness of purpose if this method fails to perform as stated or intended. • For a complete copy of Standard 62.1-2010, refer to the American Standard of Heating and Air Conditioning Engineers (ASHRAE) website at www.ashrae.org. • For more information on how to properly size a ventilation air pretreatment system, refer to the article, “Selecting DOAS Equipment with Reserve Capacity” by John Murphy, published in the ASHRAE Journal, April 2010. Method 1: Decoupled Dedicated Outdoor Air System (DDOAS) Advantages • Does not add additional heating or cooling loads to indoor units. • May be used with all single zone systems. • If the outdoor air unit fails, the resulting untreated air will be readily noticed by the occupants. • The outdoor air unit may supply “neutral” air to the occupant space even when the single zone system indoor unit fan changes speed or cycles on and off. DDOAS controls do not have to be interlocked with the single zone system. • In lieu of installing localized smaller outside air treatment equipment throughout the building, this method centralizes the ventilation air source making service and filter changes easier and less disruptive for the building occupants. Disadvantages • Ceiling space is required to accommodate ductwork between the centralized outdoor air unit and ceiling diffusers. LG recommends using the DDOAS method in all installations. Provide a separate, dedicated outdoor-air system designed to filter, condition, and dehumidify ventilation air and deliver it directly to the conditioned space through a separate register or grille. This approach requires a separate independent ventilation duct system not associated with single systems (Figure 23). Methodology illustrations are for examples only and do not depict actual indoor units for the specific outdoor unit pairing. These are generic illustrations to show ventilation design only.. Figure 23: Decoupled Dedicated Outdoor System Diagram • Indoor unit operation and performance will not be affected by the condition of outdoor air. • Third-party demand control ventilation controls are more readily accommodated.

All rights reserved. “LG ” is a registered trademark of LG Corp. 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. Refer to Figure 8. Advantages • Occupants control the volume of the ventilation air manually. • Useful for historic buildings that have no ceiling space available for outdoor air ductwork. • May be used with all single zone systems. Disadvantages • In some locations, it may be difficult to control humidity levels when windows are open. • Thermal comfort levels may be substandard when windows are open. • Indoor units may have to be oversized to account for the added heating and cooling loads when windows are open. • Provides outdoor air to perimeter spaces only. Additional mechanical ventilation system may be required to satisfy require- ments for interior spaces. • Outdoor air loads may be difficult to calculate since the quantity of outdoor air is not regulated. • May affect indoor unit proper operation when open. Methodology illustrations are for examples only and do not depict actual indoor units for the specific outdoor unit pairing. These are generic illustrations to show ventilation design only. Figure 24: Unconditioned Outdoor Air (Non-Ducted) Method 3: Unconditioned Outdoor Air (Non-Ducted, Fan Assisted Ventilation) When approved by local codes, the fan assisted ventilation method uses exhaust fans to remove air from the building, and outdoor air is drawn into occupied spaces through a wall louver or gravity roof intake hood. Supply fans can also be used to push the outdoor air into the space and building positive pressure will vent the exhaust air through louvers or roof-mounted exhaust hoods. Outdoor air is neither cooled nor heated before entering the building. Refer to Figure 24. This may result in loss of building pressurization control, increasing infiltration loads with adverse effects. Advantages • Outdoor air may be manually controlled by the occupant or auto- matic controls may be installed to open/close outdoor air dampers or to turn on/off ventilation fans. • Useful for large open spaces like warehouses, garages, and workshops. • Outdoor air volume is a known quantity. Air loads may be easier to calculate since fans will regulate the amount of outdoor air. • May be used with all single zone systems. Disadvantages • In some locations of the country, it may be difficult to control humidity levels while outdoor air louvers/hoods are opened. • Thermal comfort levels may be substandard when louvers/hoods are opened. • Indoor units may have to be oversized to account for the added heating/cooling loads when louvers/hoods are open. • Hot, cold, and/or humid areas may be present if the outdoor air is not evenly distributed to the different spaces. Methodology illustrations are for examples only and do not depict actual indoor units for the specific outdoor unit pairing. These are generic illustrations to show ventilation design only.

All rights reserved. “LG ” is a registered trademark of LG Corp. PLACEMENT CONSIDERATIONS Selecting the Best Location Select a location for installing the outdoor unit that will meet the following conditions: • Where the unit will not be subjected to direct thermal radiation from other heat sources. • Where operating sound from the unit will not disturb inhabitants of surrounding buildings. • Where the unit will not be exposed to direct, strong winds. • Where there is enough strength to bear the weight of the unit. • Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode. • Include enough space for air flow and for service access. • To avoid the possibility of fire, do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. • Do not install the unit in a location where acidic solution and spray (sulfur) are often used. • Do not use the unit in environments where oil, steam, or sulfuric gas are present. • Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or severe windchill or cold: 1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena. 2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the 3. system may malfunction. 4. Remove any snow that has accumulated 3-15/16 inches or more on the top of the outdoor unit. 5. Place the outdoor unit on a raised platform at least 19-11/16 inches higher than the average annual snowfall for the area. In environments where there is a possibility of heavy snow, the frame height must be more than two (2) times the amount of average annual snowfall, and should not exceed the width of the outdoor unit. If the frame width is wider than the outdoor unit, snow may accumulate. 6. Install a snow protection hood. 7. To prevent snow and heavy rain from entering the outdoor unit, install the suction and discharge ducts facing away from direct winds. 8. Additionally, the following conditions should be taken into considerations when the unit operates in defrost mode: • If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot of natural light. (Example: Install on a rooftop.) • Sidewalks or parking lots near the outdoor unit may accumulate moisture after unit operates in defrost mode that can turn to ice. The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed: 1. In a narrow, shady location. 2. Near a location that has a lot of ground moisture. 3. In a highly humid environment. 4. In an area in which condensate does not drain properly.

All rights reserved. “LG ” is a registered trademark of LG Corp. PLACEMENT CONSIDERATIONS Outdoor Unit Installation General Mounting Securely attach the outdoor unit to a condenser pad, base rails, or another mounting platform that is securely anchored to the ground or building structure. Attach the outdoor unit with a bolt and nut on a concrete or rigid mount. See Figure 26. Refer to the applicable installation manual and follow applicable local codes for clearance, mounting, anchor and vibration attenuation requirements. All referenced materials are to be field-supplied. Images are not to scale.. Figure 26: Outdoor Unit Mounting Methods Bolt Placement & Anti-Vibration Pad Piping Connection Top of Unit Foundation Mounting Platform The underlying structure or foundation must be designed to sup- port the weight of the unit. Avoid placing the unit in a low lying area where water may accumulate. When installing the outdoor unit on the wall, or roof top, anchor the mounting base securely to account for wind, earthquake or vibration. Tie-Downs and Wind Restraints The strength of the Duct-free Split Single Zone Inverter system frame is adequate to be used with field-provided wind restraint tie- downs. The overall tie-down configuration must be approved by a local professional engineer. Always refer to local code when design- ing a wind restraint system. Snow and Ice Conditions In climates that experience snow build-up, place the unit on a raised platform to ensure condenser airflow. The raised support platform must be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a minimum height that is equal to the average annual snowfall plus 20 inches. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet guards. Best practice prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where required by local codes. When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on sidewalks or driveways. Ambient Air Conditions Avoid exposing the outdoor unit to steam, combustible gases, or other corrosive elements. Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing vents, and other sources of extreme temperature, gases, or substances that may degrade performance or cause damage to the unit. When installing multiple outdoor units, avoid placing units where the discharge of one outdoor unit will blow into the inlet side of an adjacent unit.

All rights reserved. “LG ” is a registered trademark of LG Corp. PLACEMENT CONSIDERATIONS Outdoor Unit Installation Outdoor Unit Clearance Proper clearance through 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 mount systems. Figure 27 shows the overall minimum clearances that must be observed for safe operation and adequate airflow around the outdoor unit. Figure 27: Outdoor Unit Clearances Outdoor Unit Clearance 11-3/16 27-19/32 23-19/32 11-3/16 23-19/32 Unit : inch When placing the outdoor unit under an overhang, awning, sunroof or other “roof-like structure, observe the clearance requirements (as shown in Figure 27) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not restricted around the unit. Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored. Consult local codes for rooftop mounting requirements. Do not place the unit where animals and/or plants will be in the path of the warm air, or where the warm air and/or noise will disturb neighbors. Figure 28: Outdoor Unit Sunroof/Awning Clearances More than 11-13/16 More than 11-13/16 Sunroof Fence or obstacles More than 27-19/32 Unit : inch More than 23-19/32

INSTALLATION & LAYOUT BEST PRACTICES Refrigerant Piping System Layout Physical Pipe Length: Actual length of straight segment(s) of pipe. Equivalent Pipe Length: Actual length of pipe plus equivalent lengths of elbows, Y-branches, and valves. 1. Draft a one-line diagram of the proposed piping system connecting outdoor unit to heat recovery and indoor units. Follow the pipe limitations listed on page 64. 2. Calculate the physical length of each pipe segment and note it on the drawing. 3. Calculate the equivalent pipe length of each pipe segment. Using Elbows Field-supplied elbows are allowed as long as they are designed for use with R410A refrigerant. The designer, however, should be cautious with the quantity and size of fittings used, and must account for the additional pressure losses in equivalent pipe length calculation. The equivalent pipe length of each elbow must be added to each pipe segment. See Table 40 for equivalent lengths. Table 40: Equivalent Piping Length for Piping Components. Definitions Layout Procedure Component Size (Inches) 1/4 3/8 1/2 5/8 3/4 Elbow (ft.) 0.5 0.6 0.7 0.8 1.2 Field-Provided Isolation Ball Valves It is acceptable to install field-supplied ball valves with Schrader ports at the indoor unit. Full-port isolation ball valves with Schrader ports (positioned between valve and indoor unit) rated for use with R410A refrigerant should be used on both the liquid and vapor lines. If valves are not installed and the indoor unit needs to be removed or repaired, the entire system must be shut down and evacuated. Position valves with a minimum distance of three (3) to six (6) inches of pipe on either side of the valve. Valves must be easily accessible for service. If necessary, install drywall access doors or removable ceiling panels, and position the valves to face the access door or ceiling panel open- ing. Mount valves with adequate space between them to allow for placement of adequate pope insulation around the valves. Recommended best practice is to clearly label and document locations of all service valves. The equivalent pipe length of each ball valve must be added to each pipe segment. Obstacles 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. In either case, it is imperative the horizontal section of pipe above or below the obstacle be a minimum of three (3) times greater than the longest vertical rise (or fall) distance. Refer to Figure 31. Figure 31: Installing Piping Above and Below an Obstacle Above an obstacle. 3X Below an obstacle.

REFRIGERANT PIPING DESIGN No Pipe Size Substitutions Using a different size is prohibited and may result in a system malfunction or failure to work at all. In-line Refrigeration Components Components such as oil traps, solenoid valves, filter-dryers, sight glasses, tee fittings, and other after-market accessories are not permitted on the refrigerant piping system between the outdoor unit and the indoor unit. Single Zone Wall Mount systems are provided with redundant systems that assure oil is properly returned to the compressor. Sight-glasses and solenoid valves may cause vapor to form in the liquid stream. Over time, dryers may deteriorate and introduce debris into the system. The designer and installer should verify the refrigerant piping system is free of traps, sagging pipes, sight glasses, filter dryers, etc. Pipe Supports A properly installed pipe system should be adequately supported to avoid pipe sagging. Sagging pipes become oil traps that lead to equipment malfunction. Pipe supports should never touch the pipe wall; supports shall be installed outside (around) the primary pipe insulation jacket (see Figure 31). Insulate the pipe first because pipe supports shall be installed outside (around) the primary pipe insulation jacket. Clevis hangers should be used with shields between the hangers and insulation. Field provided pipe supports should be designed to meet local codes. If allowed by code, use fiber straps or split-ring hangers suspended from the ceiling on all-thread rods (fiber straps or split ring hangers can be used as long as they do not compress the pipe insulation). Place a second layer of insulation over the pipe insulation jacket to prevent chafing and compression of the primary insulation within the confines of the support pipe clamp. A properly installed pipe system will have sufficient supports to avoid pipes from sagging during the life of the system. As necessary, place supports closer for segments where potential sagging could occur. Maximum spacing of pipe supports shall meet local codes. If local codes do not specify pipe support spacing, pipe shall be supported: • Maximum of five feet (5′) on center for straight segments of pipe up to 3/4" outside diameter size. Wherever the pipe changes direction, place a hanger within twelve (12) inches on one side and within twelve to nineteen (12 to 19) inches of the bend on the other side as shown in Figure 32. Figure 32: Pipe Hanger Details. Figure 33: Typical Pipe Support Location— Change in Pipe Direction. Figure 34: Pipe Support at Indoor Unit.

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. Refer to Figure 35. Figure 35: Pipe Sleeve Options. Diameter of penetrations shall be determined by pipe diameter plus the thickness of the insulation. Vapor Line Liquid Line Min. 18 Gauge Communications Cable Pipe Sleeve Insulation Material Insulation Material Underground Refrigerant Piping Refrigerant pipe installed underground should be routed inside a vapor tight protective sleeve to prevent insulation deterioration and water infiltration. Refrigerant pipe installed inside underground casing must be continuous without any joints. Underground refrigerant pipe must be located at a level below the frost line.

Duct-free Split Single Zone Inverter refrigeration system components contain very small capillary tubes, small orifices, electronic expansion valves, oil separators, and heat exchangers that can easily become blocked. Proper system operation depends on the installer using best practices and utmost care while assembling the piping system. • While brazing, use a dry nitrogen purge operating at a minimum pressure of three (3) psig and maintain a steady flow. • Blow clean all pipe sections with dry nitrogen prior to assembly. • Use a tubing cutter, do not use a saw to cut pipe. De-burr and clean all cuts before assembly. • Store pipe stock in a dry place. Keep pipe capped and clean. • Use adapters to assemble different sizes of pipe. • Do not use flux, soft solder, or anti-oxidant agents. • Use a 15% silver phosphorous copper brazing alloy to avoid overheating and produce good flow. • Protect isolation valves, electronic expansion valves, and other heat-sensitive control components from excessive heat with a wet rag or a heat barrier spray product Installation of Refrigerant Piping / Brazing Practices Pressure-reducing Valve Valve Taping Nitrogen Pipe to be brazed Refrigerant Piping Figure 40: Refrigerant Pipe Brazing. 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 including Y-branch and Header connections, field-provided isolation ball valves, service valves, and elbows shall be completely insulated using closed cell pipe insulation. The liquid and vapor lines must be insulated separately. To prevent heat loss/heat gain through the refrigerant piping, all refrigerant piping including liquid lines and vapor lines shall be insulated separately. Insulation shall be a minimum 1/2″ thick, and thickness may need to be increased based on ambient conditions and local codes. All insulation joints shall be glued with no air gaps. Insulation material shall fit snugly against the refrigeration pipe with no air space between it and the pipe. Insulation passing through pipe hangers, inside conduit, and/or sleeves must not be compressed. Protect insulation inside hangers and supports with a second layer. All pipe insulation exposed to the sun and outdoor elements shall be properly protected with PVC, aluminum vapor barrier, or alternatively placed in a weather-resistant enclosure such as a pipe rack with a top cover; and meet local codes. The design engineer should perform calculations to determine if the factory-supplied insulation jackets are sufficient to meet local codes and avoid sweating. Add additional insulation if necessary. Mark all pipes at the point where the insulation jacket ends. Remove the jacket. Install field provided insulation on the run-out and main truck pipes first. Peel the adhesive glue protector slip from the insulation jacked and install the clam-shell jacket over the fitting.
