Safety Precautions
LG Smart Inverter Monitoring System (SIMs) 2.0 is for use
with LG duct-free split (DFS) systems only. Do not attempt
to use SIMs 2.0 with any other type of system.
The information in this manual is intended for use by an
industry-qualied, experienced, certied technician familiar
with the U.S. National Electric Code (NEC) who is equipped
with the proper tools and test instruments.
Failure to carefully read and follow all instructions in this manual may
result in equipment malfunction, property damage, personal injury
and/or death.
Input power to the outdoor unit remains connected and
on during procedures in this manual. Do not touch any
exposed outdoor unit wiring, terminals, or other electri-
cal components with tools or exposed skin. Only qualied
technicians should install, remove, or re-install this unit.
Improper installation or use may result in re, explosion, electric
shock, physical injury and/or death.
All electrical work must be performed by a licensed electri-
cian and conform to local building codes or, in the absence
of local codes, with the National Electrical Code, and the
instructions given in this manual.
If the power source capacity is inadequate or the electric work is not
performed properly, it may result in re, electric shock, physical injury
and/or death.
Do not install the SIMs unit if it will be exposed to rain or
other precipitation. Do not install the unit in a location
exposed to open ame or extreme heat. Do not touch the
unit with wet hands.
There is risk of re, electric shock, explosion, physical injury and/or death.
Safely dispose of the packing materials.
Tear apart and throw away plastic packaging bags so that children
may not play with them and risk suffocation and death.

LG Smart Inverter Monitoring system 2.0
This manual describes how to install and
use the LG Smart Inverter Monitoring system
(SIMs) 2.0, Model PSWMOZ3. SIMs consists
of a hardware Wireless Local Area Network
(WLAN) module, an interface cable, and a free
application (app) for iOS and Android. The
user must supply a smart phone, either an
Apple iPhone or an Android phone. SIMs is not
optimized for tablets.
Before using SIMs, you must download and
install the latest version of the free SIMs
app from either the App store (iOS) or the
Play Store (Android). Be sure to download
the WLAN version of the app. There is also
a Bluetooth version (LG SIMs 1.0 [Bluetooth
Only]) on the Play Store, but the Bluetooth version will not work
with this WLAN SIMs module. Be sure to download LG SIMs 2.0.
Figure 1 shows the SIMs app and SIMs WLAN module in a typical
DFS application. Table 1 lists SIMs smart phone requirements.
The SIMs WLAN module and the smartphone app together provide
monitoring and troubleshooting capability for LG duct-free systems
(DFS). SIMs functions only with LG DFS products.

Figure 1: SIMs WLAN Module to Typical DFS System
SIMs can display and graph operational data for the air conditioner
system including the indoor unit and the outdoor unit. SIMs also
displays error codes and a troubleshooting guide.
To use SIMs you must be a trained HVAC service technician
familiar with variable refrigerant flow (VRF) systems in general and
with LG’s DFS products. You should understand the inverter air
conditioning operation cycle, the meaning of the data displayed by
SIMs, and how to use the data to troubleshoot the system.
The DFS air conditioning system must run for at least
15–20 minutes before data collected by SIMs 2.0 is valid
for troubleshooting.

LG SIMs 2.0
LG SIMs 2.0 Operating Considerations
• LG SIMs 2.0 processes data in real time. If other functions of
the smart phone are used at the same time as SIMs, smart
phone resources may be insufcient for SIMs to process data
or the SIMs connection may be disconnected. Please use the
product with this in mind. Always use a smart phone with at
least the minimum recommended specications.
• The SIMs application may unexpectedly end due to insufcient
system resources.
• Transmission/reception data volume may increase according
to the number of indoor and outdoor units. SIMs response
speed may be slower for some smart phone specications.
• Wireless transmission/reception distance may be reduced or
communication may be disconnected due to the operational
environment (weather, electromagnetic interference or
physical obstacles).
• SIMs may not work correctly with rooted smart phones.
• As communication distance between the SIMs WLAN module
and the smart phone increases, smart phone WLAN output
may increase, causing greater drain on the smart phone
battery. During use, keep the smart phone as close as safely
possible to the SIMs WLAN module.

User Manual
Safety
Safety of personnel is the primary concern during all procedures.
Read and understand the safety summary at the front of this manual.
Read and understand this installation procedure before beginning
installation. Use the appropriate tools and acccessories during instal-
lation. Plan your work and do not work alone, if possible. Know how to
obtain emergency medical and reghting assistance.
Installation Sequence
To use SIMs, you must install the app on your smart phone and
you must connect the WLAN module to the outdoor unit. If you
have not yet installed the app, it may be more convenient to do so
before arriving at the job site. If desired, you can skip ahead to
the app installation section and return to WLAN module installation
when you are on-site.
Install the SIMs WLAN Module
The SIMs WLAN module must connect to the LGMV connector
on the outdoor unit’s circuit board. Most outdoor units have an
extension cable connected to the LGMV connector. To access the
extension cable you have to remove only the side handle cover.
Some outdoor units may not have the extension cable. If not, you
must remove the top cover of the outdoor unit and connect the
SIMs cable directly to the LGMV connector on the circuit board.
High voltages capable of causing death are used in this equipment.
Outdoor unit power remains connected during this procedure. Take
extreme caution not to touch electrical components or connections.
Failure to observe this warning can result in death or severe injury.
Note:
Some ODUs have an LGMV extension cable accessed by
removing the side handle cover. If the ODU does not have this extension
cable, access the LGMV connector by removing the top cover of the ODU.
1. Remove the outdoor unit handle cover.

2. Locate the cable labeled MVC Jig inside the outdoor unit. If this
cable is not there, reinstall the handle cover and remove the
top cover of the outdoor unit.
3. Locate the SIMs WLAN module and the SIMs
interface cable.
4. Connect USB connector on the interface cable
to USB connector on the SIMs WLAN module.
5. If the MVC Jig cable is present, connect the
other end of the interface cable to the MVC
Jig cable connector.
6. If the MVC Jig cable is not present, connect the
other end of the interface cable to the LGMV
connector on the outdoor unit circuit board.
