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).

Do Not’s

• Where there are 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 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 (8)

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 (minimum 24 inches); 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 branch distribution unit.

Do Not’s

• Install the branch distribution unit in a location where it would be subjected to strong radiation heat from heat sources.

• Install in an installation environment where the branch distribution unit would be exposed to heat, water, steam, oil splattering or spray.

• Install the unit in a location where any sound it generates will disturb occupants in the surrounding rooms.

• No obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.

• Install in an area where high-frequency electrical noise / electromagnetic waves will affect operation. Maintain proper distances between the

branch distribution unit(s) and electric wires, audio and visual appliances, breaker / circuit panels, etc.

PLACEMENT CONSIDERATIONS

%UDQFK'LVWULEXWLRQ8QLWV

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 environment 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.

For detailed placement considerations and installation requirements for indoor units, refer to its Indoor Unit Engineering and /

or Installation Manuals.
