DescriptionWhen you install an LG Multi Zone System, you will also need branch distribution boxes as part of the installation. A branch distribution box is used to connect line sets from the outdoor unit to the individual indoor units. LG offers four different boxes. They include this 3 unit Branch Distribution (BD) box, the PMBD3630, the 2 unit PMBD3620 and two 4 unit boxes - PMBD3640 and PMBD3641 (with one integral 36k unit adaptor).The PMBD3630 unit is rated for a maximum of 72,000 BTUs (24,000 BTUs/port). Each branch distribution unit is specific to the number of indoor units you will be using. This distribution box is required when connecting 2 or three indoor units to a single outdoor compressor. The number and size of BDs you will need depends on how many indoor units you plan on installing. However, you do not need to use all the ports available at the time of your initial installation. If you think you will be adding additional indoor units in the future, you can "cap off" the unused ports on the branch distribution units until that later time.
Below is an installation example requiring two branch distribution boxes. The outdoor unit (LMU540HV), and a Y connector/branch are also shown and the connections to the indoor units are illustrated. (Each of the distribution boxes shown below are either 3 unit or 4 unit BDs.) Of course, with the help of our sales staff, you can customize your indoor units to your requirements.
When installing two branch distribution units, you will also need to install a "Y branch" (PMBL5620) to the line set to one of the branch distribution units.
