Installation
Condensate connections
The unit must be perfectly level in
both directions. Connect the indoor
unit's condensate tray to a
condensate drainage line. The unit is
equipped with a 20 mm diameter
smooth tube connection. To ensure
correct condensate flow, the
drainage tube must be given a
10° slope. There must not be a
condensate trap at any point in the
line. However, a trap can be
provided to prevent outside air from
being taken in by the indoor unit. If
the tube enters a room, insulate it to
prevent condensation damage.
