Warning: You must connect air ducts to both the inlet and outlet, in order to ensure
appropriate IP protection, if you discover moist condensation on the ceiling above the
appliance.
Operation using an air duct results in the loss of some air-flow and heat pump capacity
in the system. If you do not connect air duct to the appliance, you must ensure within
the room that no moist or condensation may occur in the space above the appliance
in any case.
