Combining Heat Recovery Ports for Large Indoor Units
It is necessary to combine two ports on a system designed for heat recovery operation when installing a single indoor unit with a capacity
exceeding 54,000 Btu/h. Two neighboring heat recovery ports are combined using a reverse Y-branch that is then connected to the one large
indoor unit.
