Control


For residential projects Case 2 must be followed.
If the same air pressure exists between the units and the hallways, the pathways between the units
must be sealed to prevent ETS transfer.


Note that Case 2 does not require a negative pressure differential for each unit, only that the unit
does not leak too much air.
