Branch Distribution Unit Orientation
Multi F MAX 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 branch distribution units include electronic expansion 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.
