Manual / Bedienungsanleitung

When connecting to the condensed water tray, ensure that the condensed water pipe is connected to a self-filling siphon with return protection and that the condensed water pipe has a drop.

The height of the siphon must be designed for an under or overpressure of 800 Pa so that air is not drawn in or blown out of the waste pipe.
