• Indoor Units (IDUs) must not be placed in an environment where the IDUs will be exposed to harmful volatile organic compounds (VOCs) or
in environments where there is improper air make up or supply or inadequate ventilation. If there are concerns about VOCs in the environ-
ment where the IDUs are installed, proper air make up or supply and/ or adequate ventilation must be provided. Additionally, in buildings
where IDUs will be exposed to VOCs consider a factory-applied epoxy coating to the fan coils for each IDU.

electric wires, audio and visual appliances, breaker / circuit panels, etc. If the frequency signal of the appliance is unstable, then install the
indoor unit a minimum of ten (10) feet away, and run the power and transmission cables through a conduit.
• An area that is level and with enough strength to bear the weight of the indoor unit(s).
• No obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.
• An area where operation sound won’t disturb occupants.
• An area that does not expose the indoor unit(s) to heat, water, steam, oil splattering or spray.

piping and wire lengths must not exceed amounts specified by LG Electronics, U.S.A., Inc.
• Condensate drain piping is not required.
• Ensure there is enough space in the installation area for service purposes; install the refrigerant piping and electrical wiring system in an
easily accessible location.
• Level where there is enough strength to bear the weight of the BD unit.
•
Do not install the BD unit in a location where it would be subjected to strong radiation heat from heat sources.
•
Avoid an installation environment where the BD unit would be exposed to heat, water, steam, oil splattering or spray.
• Install the unit in a location where any sound it generates will not disturb occupants in the surrounding rooms.
• No obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.
