A1=>A2 (A1) If there is danger of drainage dripping and freezing between the upper and
lower units…
(A2) Then install a roof between the upper and lower units. 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.
Note: For better serviceability, use a side by side distance ≥250 mm (instead of
≥100mm as shown on the figures above).
