3. Interchange any two of the field connected main
power wires at the unit terminal block or the factory
mounted disconnect switch.
NNoottee:: Interchanging “Load” side power wires at the
fan contactors will only affect the individual
fan rotation. Ensure that the voltage phase
sequence at the main terminal block or the
factory mounted disconnect switch is ABC as
outlined in the “Unit Startup_Electrical
Phasing,” p. 105 section.
If some of the fans are rotating backwards:
1. Press the STOP key at the Human Interface Module
in the unit control panel to stop the fan operation.
2. Open the field supplied disconnect switch upstream
of the rooftop unit. Lock the disconnect switch in
