Methods of installing a multi-unit support duct system

A method of installing a multi-unit support duct system, the method comprising:

• installing a support duct frame at an installation location, the support duct frame defining a longitudinal axis and including:
• a first longitudinal frame member and a second longitudinal frame member that is parallel to the first longitudinal frame member;
• a plurality of mounting bracket supports, each of the plurality of mounting bracket supports extending between the first longitudinal frame member and the second longitudinal frame member in a direction that is at least substantially orthogonal to the longitudinal axis of the support duct frame, each of the plurality of mounting bracket supports being movable along the longitudinal axis of the support duct frame;
• a plurality of mounting brackets, each of the plurality of mounting brackets being rotatably coupled to a corresponding one of the plurality of mounting bracket supports;
• and
• an air duct extending within the support duct frame, the air duct including a plurality of cooling unit inlets, each of the plurality of cooling unit inlets being in fluid communication with a corresponding one of the plurality of cooling units and being at least partially defined by a corresponding one of the plurality of mounting brackets;
• coupling a cooling unit to each of the plurality of mounting brackets such that each cooling unit is rotatable relative to the support duct frame, each of the plurality of cooling units being in a first configuration relative to the longitudinal axis of the support duct frame;
• and
• independently rotating at least one of the plurality of cooling units from the first configuration to a second configuration relative to the support duct frame.
