GENERAL INSTALLATION GUIDELINES
Location for Multi F MAX Branch Distribution Units
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 and inspection purposes (23-5/8 inch square opening).
• 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.
• Interior installation is highly recommended.
•
• Unit can be installed no more than ±5 degrees of level.
• 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, spray or other factors that may
damage the PCB.
• 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.
