Intake and Discharge positions are not labeled because
they are configurable by rotation of the unit about the
vertical axis. The supply and exhaust can be on either
side, but the intake/discharge relationship must be
maintained. For example, Outdoor Air Intake = Intake
Side “B”/Outdoor Air Discharge = Discharge Side “B”.
The preferred configuration is to have the energy wheel
motor in the exhaust airstream.
