How do you connect 5 air handlers to the branch box?
Bobby I 
from Mississippi 
July 10, 2017
Answer
To connect more than 4 air handlers, you will need to use 2 branch boxes. You will need to purchase a PMBL5620 Distribution Pipe Assembly to connect the second branch box.

What is the difference between the LG PMBD3641 and the PMBD3640? Also - I know you can buy adapters, but the output ports on these branch units is 1/4X3/8. Most of the LG units larger than 12K BTU's require 1/4X1/2. Does this impact performance by stepping the size down? Do you recommend stepping down at the branch box or at the wall unit?
Chris 
from Washington 
October 19, 2016
Answer
The PMBD3640 is the standard option for an LG 4 port brnach box. The PMBD3641 includes a larger port specifically for use with the a 36k BTU indoor unit. Unless you are using one of these indoor units, there is no benefit to using the PMBD3641.

LG includes any necessary port adapters with the air handlers,so they do not need to be purchased separately. They specify specific line set sizes based on the capacity of the indoor unit, and the size of the line set, along with the connections available on the indoor unit and branch box, dictates the location of the adapters. The adapters may introduce a minimal restriction, but this is insignificant to the efficiency or performance of the system. Using a line set size other than the one LG prescribes could result in poor performance.
