PLACEMENT CONSIDERATIONS
Selecting the Best Location for the Indoor Units
Select a location for installing the indoor units that will meet the following conditions:
• Within allowable parameters for proper connection to the outdoor unit (or Branch Distribution unit, if a Multi F MAX system).
• So that condensation drainage can be conveniently routed away.
• Include enough space around the indoor unit so that it is accessible for maintenance and service purposes.
• Where electrical noise / electromagnetic waves will not affect indoor unit operation. Maintain proper distances between the indoor units and
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.
Selecting the Best Location for the Outdoor Unit
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.

so will cause serious bodily injury or death.
Do not install the unit in a location where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death.
Do not use the unit in environments where oil, steam, or sulfuric gas are present as this may cause serious bodily injury or death.
WARNING
Selecting the Best Location for the Branch Distribution (BD) Unit
Branch Distribution (BD) units are used only with Multi F MAX systems to distribute the refrigerant from the outdoor unit to up to eight indoor
units. Select location indoors that will meet the following conditions:
• Within allowable parameters for proper connection to the Multi F MAX outdoor unit and indoor unit(s); refrigerant 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.
• Where high-frequency electrical noise / electromagnetic waves will not affect operation. Maintain proper distances between the BD unit(s)
and electric wires, audio and visual appliances, breaker / circuit panels, etc.
Select a location for installing the outdoor unit that will meet the following general conditions:
• A location strong enough 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, indoor unit(s), and BD units (Multi F MAX systems only) 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.
