The metal trays prevent the accumulation of condensate in this area and they must be checked for correct
positioning (cf. Fig. 23 and Fig. 24).
2. Attach mounting bracket with anti-vibration dampers (4x; included in delivery) to the lower side walls with metal
screws (see Fig. 25 and Fig. 26).
3. Mount the unit to the ceiling with long M8 threaded rods (see Fig. 26).
4.3 Install ball siphon
4.3.1 Variant 1: Installation on unit
During heating periods, condensate may form in the heat exchanger due to the heat recovery process. The condensa-
te must be able to drain freely from the unit. The provided ball siphon (scope of delivery) must be installed in the base
tray of the unit for this purpose.
1. Open ball siphon. Turn the mounting part a 1/4 turn (see Fig. 27).
2. Plug the mounting part in the condensate outlet from below, until the claw fasteners snap to the sheet edge of the
base plate (Fig. 28).
