Start at the bottom to mount the external panels (Figure 61).
For roof units also the supplied slide bar must be mounted on the roof flange.
5.1.5 Special features for roof units and device separations at wet areas
For roof units as well as at device separations directly before or after a wet area (e.g. cooler, hu-
midifier, air washer), special actions for sealing the AHU must be carried out:
1. The sealing agent (Sikaflex) has to be applied instead of the sealing strip across the whole
flange of the unit, 5 mm from the inner edge (see Figure 63 and Figure 65). Immediately
thereafter, the relevant delivery sections have to be moved together and then screwed togeth-
er.
2. If the unit separation is accessible at the inside via a door (see Figure 66), then the joints
(Figure 67) have to be closed over the entire circumference with the supplied sealing agent
(Sikaflex) after screwing together the delivery sections (Figure 58 and Figure 59).
