LG AIR CONDITIONER
TECHNICAL SOLUTION (LATS)
LG Air Conditioner Technical Solution (LATS) Software
A properly designed and installed refrigerant piping system is critical to the optimal performance of LG air-conditioning systems. To assist
engineers, LG offers, free of charge, LG Air Conditioner Technical Solution (LATS) software—a total design solution for LG air conditioning
systems. Contact your LG Rep for the best software program for your application.
To reduce the risk of designing an improper applied system or one that will not operate correctly, LG requires that LATS software be used on all projects.
Formats
LATS is available to LG customers in three user interfaces: LATS HVAC, LATS CAD2, and LATS Revit. All three LATS formats are available
through www.myLGHVAC.com, or contact an LG Sales Representative.
LATS HVAC is a Windows®-based application that aids engineers in designing LG Variable Refrigerant Flow (VRF), Multi F / Multi F MAX,
Single-Zone, and Energy Recovery Ventilator (ERV) systems.
*Windows® is a registered mark of Microsoft® Corporation.
Figure 1:Example of LATS CAD2.
Introduction
LATS CAD2 combines the LG LATS program with AutoCAD®
software**. It permits engineers to layout and validate LG Multi V
Variable Refrigerant Flow (VRF), Multi F / Multi F MAX, Single-Zone,
and Energy Recovery Ventilator (ERV) systems directly into CAD
drawings.
LATS Revit integrates the LG LATS program with Revit® software**.
It permits engineers to layout and validate Multi V VRF systems
directly into Revit drawings.
**AutoCAD® and Revit® are both registered marks of Autodesk, Inc.
Features
All LG product design criteria have been loaded into the program,
making LATS simple to use: double click or drag and drop the component choices. Build systems in Tree Mode where the refrigerant
system can be viewed. Switch to a Schematic diagram to see the
electrical and communications wiring.
LATS software permits the user to input region data, indoor and outdoor design temperatures, modify humidity default values, zoning, specify
type and size of outdoor units and indoor units, and input air flow and external static pressure (ESP) for ducted indoor units.
The program can also:
• Import building loads from a separate Excel file.
• Present options for outdoor unit auto selection.
• Automatically calculate component capacity based on design
conditions for the chosen region.
• Verify if the height differences between the various system
components are within system limits.
• Provide the correct size of each refrigerant piping segment and LG
Y-Branches and Headers.
• Adjust overall piping system length when elbows are added.
• Check for component piping limitations and flag if any parameters
are broken.
• Factor operation and capacity for defrost operation.
• Calculate refrigerant charge, noting any additional trim charge.
• Suggest accessories for indoor units and outdoor units.
• Run system simulation.
Features depend on which LATS program is being used, and the type of system being designed.
Due to our policy of continuous product innovation, some specifications may change without notification.

LG AIR CONDITIONER
TECHNICAL SOLUTION (LATS)
LATS Generates a Complete Project Report
Single Zone Art CoolTM Mirror Wall Mount Engineering Manual
LATS software also generates a report containing project design parameters, cooling and heating design data, system component performance, and capacity data. The report includes system combination ratio and refrigerant charge calculations; and provides detailed bill of
material, including outdoor units, indoor units, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe
size, and by pipe segments. LATS can generate an Excel GERP report that can imported into the LG SOPS pricing and ordering system.
Proper Design to Install Procedure
LG encourages a two report design-to-install-procedure. After the
design engineer determines building / zone loads and other details,
the engineer opens the LATS program and inputs the project’s
information. When the design is complete, the “Auto Piping” and
“System Check” functions must be used to verify piping sizes,
limitations, and if any design errors are present. If errors are found,
engineers must adjust the design, and run Auto Piping and System Check again. When the design passes the checks, then the
engineer prints out a proj ect “Shop Drawing” (LATS Tree Diagram)
and provides it to the installing contractor. The contractor must
follow the LATS Tree Diagram when building the piping system, but
oftentimes the design changes on the building site:
•
•
•
•
Figure 2:Example of a LATS Tree Diagram.
Architect has changed location and/or purpose of room(s).
Outdoor unit cannot be placed where originally intended.
Structural elements prevent routing the piping as planned.
Air conditioning system conflicts with other building systems (plumbing, gas lines, etc.).
The contractor must mark any deviation from the design on the Shop Drawing, including as-built straight lines and elbows. This “Mark Up”
drawing must be returned to the design engineer or Rep, who must input contractor changes into the LATS file. (Copy the original LATS software file, save and rename as a separate file, and modify all piping lengths by double-clicking on each length and editing information.) Like
the shop drawing, the Auto Piping and System Check must also be run on this new “As Built” drawing. The design engineer or Rep must then
provide the final As Built file to the contractor. The Mark Up version must be compared to the As Built version for the following:
• Differences in pipe diameter(s). If incorrect diameters have been installed, the piping must be changed out. If pipe diameters have changed,
check to see if Y-Branches will also need to be changed.
• Changes to outdoor unit and indoor unit capacities. Capacities changes may impact line length changes.
• Additional refrigerant charge quantity (“Trim Charge”). Trim charge will change if piping lengths and diameters change. The As Built version
must reflect installed piping lengths to ensure correct trim charge.
All documents submitted by the contractor, as well as the Shop Drawing and the As Built Drawing files must be provided for commissioning
purposes. Model and serial numbers for all system components must also be submitted. If the steps previously detailed are not followed, and
all documents are not provided to the LG trained Commissioner, the project runs the risk of not being commissioned and voiding any limited
warranty LG offers on the equipment.

Indoor Units
Indoor Unit Sound Pressure Measurement
Figure 11: Art Cool Mirror Indoor Unit Sound Level Measurement.
• Measurements are taken 3.3 ft away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of
±3.
• Data is valid at nominal operation conditions. Operating conditions
are assumed to be standard.
• Reference acoustic pressure 0dB=20μPa
• Sound pressure levels are tested in an anechoic chamber under
ISO Standard 3745, and may be different according to the test
condition or equipment.
• Sound level will vary depending on a range of factors including the
construction (acoustic absorption coefficient) of a particular room in
which the unit was installed.

General Power Wiring / Communications Cable Guidelines
•
•
•
•
•
•
•
•
Follow manufacturer’s circuit diagrams displayed on the inside of the control box cover.
Have a separate power supply for the indoor units.
Provide a circuit breaker switch between the power source and the indoor unit.
Confirm power source specifications.
Properly ground the outdoor unit and the indoor unit per NEC and local codes.
Connect the wiring firmly so that the wires cannot be easily pulled out.
Confirm that the electrical capacity is sufficient.
Power supply to the outdoor unit must be selected based on NEC and local codes. Maximum allowable voltage fluctuation ±10% or nameplate rated value.
• It is recommended that a circuit breaker is installed, especially if conditions could become wet or moist.
• Include a disconnect in the power wiring system. Add an air gap contact separation of at least 1/8 inch in each active (phase) conductor.
• Any openings where the field wiring enters the cabinet must be completely sealed.
Do not install power wiring to the outdoor unit and the communication / connection (power) cable to the indoor unit in the same conduit.
Use separate conduits.
Power Wiring / Communications Cable Specifications
• Power wiring to the outdoor unit must be solid or stranded, and must comply with the applicable local and national electric codes.
• Communication cable from the outdoor unit to the indoor unit must be a minimum of 18 AWG, four (4) conductor, shielded or unshielded (if
shielded, must be grounded to chassis at ODU only) and must comply with applicable local and national codes.
• Communication cable from indoor unit to remote controller(s) is to be 22 AWG, 3-conductor, twisted, stranded, unshielded. Wiring must
comply with all applicable local and national codes.
• Terminal screws may become loose during transport. Properly tighten the terminal connections during installation or risk electric shock,
physical injury, or death.
• Loose wiring may cause unit to malfunction, overheat, and catch fire, resulting in severe injury or death.
• Terminal screws may loosen during transport. Properly tighten the terminal connections during installation or risk equipment malfunction or
property damage.
• Loose wiring may cause unit malfunction, the wires to burnout or the terminal to overheat and catch fire. There is a risk of equipment malfunction or property damage.
A voltage drop may cause the following problems:
• Magnetic switch vibration, fuse breaks, or disturbance to the normal function of an overload protection device.
• Compressor will not receive the proper starting current.

Wired Controller Placement
Wired controllers include a sensor to detect room temperature. To
maintain comfort levels in the conditioned space, the wired controller must be installed in a location away from direct sunlight, high
humidity, and where it could be directly exposed to cold air. Controller must be installed four (4) to five (5) feet above the floor where its
LED display can be read easily, in an area with good air circulation,
and where it can detect an average room temperature.
•
•
•
•
•
Do not install the wired controller near or in:
Drafts or dead spots behind doors and in corners.
Hot or cold air from ducts.
Radiant heat from the sun or appliances.
Concealed pipes and chimneys.
An area where temperatures are uncontrolled, such as an outside
wall.

Each indoor unit includes a return air thermistor assigned to sense the temperature. If a wired controller is installed, there is a choice of
sensing temperature with either the indoor unit return air thermistor or the thermistor in the wired controller. It is also an option to set both
thermistors to sense temperature so that indoor unit bases its operation on the first thermistor to reach the designated temperature differential.

ACCESSORIES
Single Zone Art CoolTM Mirror Wall Mount Engineering Manual
LG Smart Inverter Monitoring System (SIMS)
SIMS can be used to display and graph operational data for single zone systems and respective components (indoor unit and outdoor unit). SIMS also displays error codes and a troubleshooting guide.
SIMs consists of a hardware Wireless Local Area Network (WLAN) module, an interface cable, and a
free downloadable application (app) for iOS® or Android™. The user must supply either an Apple® or an
Android smart phone; SIMs is not optimized for tablets, and only be used with LG single zone and Multi F
systems.
Figure 41: LG SIMS WLAN
Module.
Only trained HVAC service technicians familiar with variable refrigerant flow (VRF) systems in general
and with LG’s DFS products can use SIMS. The technician must understand inverter air conditioning
operation cycles, the meaning of the data displayed by SIMS, and how to use the data to troubleshoot
the system.
iOS is a registered trademark of Cisco in the U.S. and other countries. Android is a trademark of Google Inc.
Apple is a trademark of Apple Inc., registered in the U.S. and other countries.
Contact your LG Sales Representative for system requirements, the latest version of SIMS,
how to download the app, or other information.
LG Smart ThinQ
LG Smart ThinQ is a built-in Wi-Fi module, along with a free smart phone app that provides monitoring
and remote control capabilities for certain LG single zone systems. The app has the following features
and benefits:
• Sign in to the app using LG credentials, or using Google® or Facebook® login credentials. Users only
have to log in to the app once; the app remembers login details for subsequent logins.
• View current temperature settings of the air conditioning unit and change temperature, fan speed,
and air flow direction from anywhere in the house or at a remote location (through the use of wireless
connection). Multiple users can control the household air conditioning unit remotely.
• Monitor filter usage of the unit.
• Set up weekly schedules to start and stop air conditioner activity.
• Set up the unit to run in different Modes, depending on the user’s schedule. Set up specific temperatures for when the user is home, away on vacation, or sleeping.
• Troubleshoot problems, and view tips on general maintenance of the system using the Smart Diagnosis
function.

Cooling / Heating Correction Factors
Single Zone Art CoolTM Mirror Wall Mount Engineering Manual
For Single Zone Art Cool Mirror Wall Mounted 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 below. Multiply the correction factors by the cooling or heating capacity obtained from the capacity tables
using design conditions. The resultant is the NET cooling or heating capacity.
Refrigerant Line Length Derates
For air-cooled systems, a capacity correction factor may have to be applied to account for the length of the system’s refrigerant pipe. Rate of
change in capacity due to increased piping lengths is shown below.

EQUIPMENT SELECTION PROCEDURE
Correction Factors
Defrost Correction Factor for Heating Operation
The outdoor unit heating capacity may need to be adjusted for frost accumulation on air-cooled systems. If design day conditions are below
the dewpoint of the surrounding air, frost may not be a problem and no correction factor is needed. In certain weather conditions, however,
frost may form and accumulate on the air-cooled outdoor unit coil and impact the coils ability to transfer heat. If significant frost accumulates
on the outdoor unit coil, a defrost algorithm will start automatically. The timing between defrost periods is determined by the system’s ability
to achieve a target head pressure value.
Capacity and AHRI ratings tables do not factor in capacity reduction when frost has accumulated on the condenser coil, nor during defrost
operation.
Integrated heating capacity values can be obtained using the formula:
A=BxC
Table 27: Outdoor Unit Frost Accumulation Factor (Heating)1.
Where:
A = Integrated Heating Capacity.
B = Value found in the Capacity Table.
C = Correction Factor for Frost Accumulation Factor (from table at
right).

The frost accumulation factor does not account for effects of snow accumulation restricting airflow
through the outdoor unit coil.

Check the Indoor and Outdoor Unit Selection(s)
Compare the corrected cooling and heating capacities to the load calculations. Is each capacity sufficient for the zone it serves?
For each indoor unit, the corrected capacity must be at least equal to the total of the cooling design load (plus ventilation load, if applicable)
for the space served by the indoor unit. For each indoor unit, the corrected capacity also must be at least equal to the total of the heating
design load (plus ventilation load, if applicable) for the space(s) and / or thermal zones served by the indoor unit.
The outdoor unit selected must be large enough to offset the total cooling load for all spaces it serves (account for ventilation air cooling
load if the ventilation air has not been pretreated to room neutral conditions). The outdoor unit must also be large enough to offset the total
heating load for all spaces it serves.
If the corrected heating capacity ratio exceeds 100%, reselect the equipment, or change the system design by moving some of the load to
another system.

Outdoor Unit
Selecting the Best Location for the Outdoor Unit
Single Zone Art CoolTM Mirror Engineering Manual
Do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. These conditions can cause a fire, resulting in
bodily injury or death.
•
Do not install the unit in a location where acidic solution and spray (sulfur) are often used as it can cause bodily injury or death.
•
Do not use the unit in environments where oil, steam, or sulfuric gas are present as it can cause bodily injury or death.
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, which may create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freezing,
cracking, leaking, and causing unsafe conditions from frozen condensate.
Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Follow the placement guidelines set forth in
“Clearance Requirements”.
Select a location for installing the outdoor unit that will meet the following conditions:
• Where there is enough strength to bear the weight of the outdoor unit.
• A location that allows for optimum air flow and is easily accessible for inspection, maintenance, and service.
• Where piping between the outdoor unit and indoor unit(s) are within allowable limits.
• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode. Avoid placing the outdoor unit in
a low-lying area where water could accumulate.
• 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).
Don’ts
• Where it will be subjected to direct thermal radiation from other heat sources, or an area that would expose the outdoor unit to heat or
steam like discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing vents, and other
sources of extreme temperatures.
• Where high-frequency electrical noise / electromagnetic waves will not affect operation.
• Where operating sound from the unit will disturb inhabitants of surrounding buildings.
• Where the unit will be exposed to direct, strong winds.
• Where the discharge of one outdoor unit will blow into the inlet side of an adjacent unit (when installing multiple outdoor units).
Outdoor Unit Condensate Drain Piping
Outdoor unit requires condensate drain piping. Condensate drain pipe is constructed with materials approved by local code. See Placement
Considerations for information in reference to outdoor unit placement.
Planning for Snow and Ice
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 system may malfunction.
3. Remove any snow that has accumulated four (4) inches or more on the top of the outdoor unit.
4. In climates that may experience significant snow buildup, mount the outdoor unit on a raised, field-provided platform or stand. The raised
support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum anticipated snowfall for the location.
5. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit frame.
6. Provide a field fabricated snow protection hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces.
7. To prevent snow and heavy rain from entering the outdoor unit, install the condenser air inlets and outlets facing away from direct winds.
8. Consider tie-down requirements in case of high winds or where required by local codes.

PLACEMENT CONSIDERATIONS
Outdoor Unit
Minimum Allowable Clearance and Service Access Requirements
Proper clearance for the outdoor unit coil is critical for proper operation. When installing the outdoor unit, consider service, inlet and outlet,
and minimum allowable space requirements as illustrated in the diagrams below.
• Include enough space for airflow and for service access. If installing multiple outdoor units, avoid placing the units where the discharge of
one unit will blow into the inlet side of an adjacent unit.
• If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that the discharge air of the outdoor unit isn’t restricted.
•
No obstacles to air circulation around the unit; keep proper distances from ceilings, fences, floor, walls, etc. (Install a fence to prevent
pests from damaging the unit or unauthorized individuals from accessing it.)
Single Zone Art Cool Mirror Wall Mount Outdoor Unit (9,000, 12,000, 18,000, 24,000 Capacities) Service Access and
Allowable Clearances
Specific clearance requirements in the diagram below are for 9,000, 12000, 18,000, and 24,000 Btu/h capacities. Figure below shows the
overall minimum clearances that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other “roof-like structure”, observe the clearance requirements (as
shown in Cases 1 and 2) for height in relation to the unit. To have successful service access to the outdoor unit, see the Figure below for
minimum spacing. When installing multiple outdoor units, see Cases 4 and 5 for correct spacing requirements.
Application Guidelines
If the outdoor unit is installed between standard and minimum clearances, capacity decreases approximately 10%.

PLACEMENT CONSIDERATIONS
Installing Outdoor Units Indoors
Single Zone Art CoolTM Mirror Engineering Manual
Installing Outdoor Units Indoors
Single Zone Art Cool Mirror Wall Mount outdoor units are engineered to be mounted outdoors and include technology designed to minimize
the negative effects of winter weather’s freezing rain, sleet, and snow. Some building projects, however, necessitate placing the HVAC outdoor units indoors:
• Lack of ground space.
• Lack of an appropriate outdoor location that meets system design requirements.
• When mounting on the roof is not an option due to a lack of roof space.
• Roof warranty will be voided if mechanical equipment is placed on the membrane.
• On retrofit projects, a former chiller / boiler / air handler equipment room, mechanical area, or penthouse already exists.
• To curtail the potential need for redundant zone heating devices such as wall-fin radiators or duct heaters.
• In extremely cold environments where there is a significant amount of run-time at temperatures well below freezing outside the outdoor unit
ambient air temperature range published in this engineering manual.
Benefits of Installing Outdoor Units Indoors
•
•
•
•
•
Shelters the outdoor unit from direct exposure to prevailing winds that decrease the heating capability of the outdoor unit.
Protects equipment from freezing precipitation and / or potential ice build-up that could hinder unit operation.
Maintains coil heat transfer efficiency by reducing the number of and shortening the cycle time for defrost operation.
Easier maintenance and servicing during inclement weather.
When mounted in a fully enclosed space, limiting the ambient air temperature may allow the Single Zone Art Cool Mirror Wall Mount system
designer to eliminate oversizing.
• The outdoor unit to compensate for loss of capacity at low ambient temperatures.
• May also curtail the need to provide inefficient redundant zone heating devices such as wall-fin radiators and second-stage ancillary heating devices.
Design Considerations Include:
• Enclosure types and elements such as louvers (see next page), rain hoods, dampers and controls, heating methods and sizing of heating
devices.
• Heating strategies.
• Duct design.
• Condensate handling.
General Guidelines
• Follow ASHRAE 62.1 design guidelines.
• Depending on the project / application, a roof over the outdoor units in combination with a wind break may be all that is necessary.
• Consider the potential for snow accumulation near louvers / roof openings. Outside air intakes and discharge ducts/louvers must be engineered to clear anticipated snow accumulation levels by at least one (1) foot.
• In situations where operation is anticipated at temperatures lower than the product’s minimum operating temperature, ancillary heat must
be provided to heat the outdoor unit coils to ensure continuous compressor operation and heating.
It may be necessary to use a field-fabricated air guide to prevent discharge air from short-cycling back to the coil inlet.
• Consider the direction of prevailing winds and opening placement. If possible, locate inlet openings upwind of discharge openings and other
exhaust outlets.
• When inlet and outlet openings are placed on the same wall, minimum distance between the two openings must be approximately three (3)
feet (minimum distance varies significantly with variations in outlet opening face velocity).
• If roof-mounted ventilation openings are used, strategically locate the inlet ventilation opening(s) upwind of the outlet opening(s).
• Discharge and supply ductwork must be designed to avoid weather related long periods of water entrainment and the potential for microbial
growth.

PLACEMENT CONSIDERATIONS
Installing Outdoor Units Indoors
Provide a means to drain the condensate generated during heating mode and defrost cycle in addition to rainwater that infiltrates the inlet
louver enclosed area.
• Install a field-provided drain pan under the outdoor units and provide a path to a nearby floor drain.
• If the ambient air temperature is expected to drop below 32°F in the enclosure, heat the bottom surface of the pan, drain line, and floor
drain so that the condensate does not freeze before reaching the drain.
CAUTION
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 which may create unsafe conditions.
Allow for ventilation intake and exhaust air based on maximum outdoor unit fan capacity.
• Select the size, type and orientation of architectural louvers with adequate “net free area” face velocity to ensure the total external static
pressure from the outdoor unit fan does not exceed design limitations (see specification data tables).
• No obstructions must be placed in front of the louver that could hamper the free flow (throw) of air.
• Roof top openings and / or discharge and supply louvers must be equipped with screens to prevent bird and insect infiltration.
As always, the best solution for each project balances acceptable heating performance (considering local weather conditions), capital costs,
life cycle energy consumption, and limitations set forth by local building codes.
