LG-PMBD3640
There are four branch distribution boxes available to help customize the installation of your LG Multi F Max Mini Split System. A branch distribution unit is used as an intermediate refrigerant control device between the outdoor unit and the indoor units. It is used to effectively and efficiently control the heating or cooling operation of the system through the use of electronic expansion valves. They are available with 2, 3 or 4 ports. The PMBD3640 is rated for 4 units and a maximum of 73,000 BTUs (24,000 BTUs/port).

A distribution box is required when connecting 2 or more indoor units to a single outdoor compressor. 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. Each branch distribution unit is specific to the number of indoor units you will be using.
  • 2 port unit - PMBD3620
  • 3 port unit - PMBD3630
  • 4 port unit - PMBD3640
  • 4 port unit with one integral 36k unit adaptor - PMBD3641
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.) The indoor units shown include 1 ceiling cassette, 2 standard high wall units, a mirrored art cool unit and 2 ducted concealed ceiling unit. This item is only the Branch Distribution Box.

Each indoor unit has its own control, so each room can be set to different temperatures. In this example installation, the individual units are connected to a single exterior unit by way of the 2 branch provider units and 1 "y" connector.
