Service space: Outdoor unit
When mounting units side by side, the piping route must be to the front, to the back or downwards. In this case the piping route to the side is
not possible.
When mounting the units side by side and routing the piping to the back, you must keep a distance of ≥250 mm between the units (instead of
≥100 mm as shown on the figures below).

(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.
