  • Description

    A branch distribution box is required when installing the LG Multi Zone Mini Split System. It acts as a portal for the line sets that connect the outdoor unit to the individual indoor units. There are four branch distribution boxes available to help customize your installation. The PMBD3620 is a 2 port unit and required when installing/connecting 2 indoor units. This BD unit is rated for a maximum of 48,000 BTUs (24,000 BTUs/port).

    Other available distribution boxes include:
    • 3 port unit - PMBD3630
    • 4 port unit - PMBD3640
    • 4 port unit with one integral 36k unit adaptor - PMBD3641
    Each branch distribution unit is specific to the number of indoor units you will be using. Depending on how many indoor units you will be installing, the correct size distribution unit needs to be installed. 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. 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.

    Below is an installation example. With the Multi F Max 54,000 BTU unit, you can supply anywhere from 2 to 8 rooms with their own climate control. The photo below illustrates an example of a 6 zone installation. This installation requires one outdoor unit (LMU540HV), a Y connector/branch, and two branch distribution boxes. (Each of the distribution boxes shown below are either 3 unit or 4 unit BDs.) With the help of our sales staff, you can customize your indoor units to your requirements.

    The LMU540HV is rated at 54,000 BTUs and can be connected to almost any combination of indoor units up to 8, totaling 73,000 BTUs (max.). The unit must be connected to a minimum of 2 units with a combined BTU rating of 24,000 BTUs.
