Multi F MAX with LGRED branch distribution units can be installed in a multitude of options to fit various building configurations and job or
application requirements. The installation location of the PCB within the branch distribution unit can be changed for easier service access,
depending on the branch distribution unit installation itself. Multi F MAX with LGRED branch distribution units include electronic expan-
sion valves that properly seat only if the branch distribution unit is installed in an acceptable orientation. Installations with improper branch
distribution unit orientation risk incomplete valve seating and system performance degradation from potential refrigerant leakage through the
electronic expansion valve. See the Branch Distribution Product Section for acceptable installation options.
