The SIMs WLAN module and the smart phone app together provide monitoring and

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 trouble-
shooting guide. A full copy of the LG SIMs Smart Inverter Monitoring System User’s
Manual is available on the www.lghvac.com website.
To use SIMs, you must be a trained HVAC service technician familiar with variable
refrigerant flow (VRF) systems in general, and with LG’s Duct Free System products.
You must 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 Duct Free System air conditioning system must
run for at least 15–20 minutes before data collected
by SIMs is valid for troubleshooting.
• The free SIMs app must be correctly installed on
the smart phone before using SIMs.
• Some outdoor units have an LGMV extension cable
accessed by removing the side handle cover. If the
outdoor unit does not have this extension cable,
access the LGMV connector by removing the top
cover of the outdoor unit.
High voltages capable of causing death are used
in this equipment. Outdoor unit power remains con-
nected 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.
