PLACEMENT CONSIDERATIONS
Selecting the Best Location for the Indoor Units /
Branch Distribution Units
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 (and branch distribution unit, if a Multi F MAX with LGRED 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).
Dont'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.
Indoor units (IDUs) should not be placed in an environment where the IDUs may 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 should 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.
Selecting the Best Location for the Branch Distribution (BD) Units
Branch distribution (BD) units are used only with Multi F MAX with LGRED systems to distribute the refrigerant from the outdoor unit up to six
(6) indoor units. Select a location indoors that will meet the following conditions:
• Within allowable parameters for proper connection to the Multi F MAX with LGRED 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.
Dont'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.
