Install the upper unit high enough above the lower unit to prevent ice buildup at the upper unit’s bottom plate. B1=>B2 (B1) If there is no danger of drainage dripping and freezing between the upper and lower units… (B2) Then it is not required to install a roof, but seal the gap between the upper and lower units to prevent discharged air from flowing back to the suction side through the bottom of the unit.
