Combination AHU in weather-resistant execution side by side
If parts of outdoor AHUs are set up side by side, then the metal sheet roof, which overlaps both
parts of the AHU, has to be mounted on site. The scope of supply includes as follows:
-
All parts of the AHU with roof inside panel inclusive insulation. The height difference of the roof
inside panels on the edges, which cross to the corner profiles, and the top edge of the corner
profiles is compensated by a sealing strip and / or a double-sided tape (see
Figure 97
).

-
A metal sheet roof, which overlaps the entire width with pre-punched holes. Those are to screw
the metal sheet roof onto the top of the device.
-
Sealant (Sikaflex) (see
Figure 99
)
-
Drilling screws with a sealing washer. (see
Figure 98
)

Metal sheet roof mounted
At the assembly of the metal sheet roof, proceed as follows:
-
Put on the roof sheet according the AHU drawing. Leave the dripping edge 50 mm over. Adjust
the sheet edge parallel to the AHU edge.
-
Initially, mark the screw holes (as a guide, similar to using a template with a marker type pen)
on the roof sheet at the corner profiles of the inner panel. This then enables the fitter to place
the roof sheet on accurately, once the protective tape foil has been removed and any applica-
tion of silicon, by guiding the roof plate to the pre-marked holes.
-
Remove the roof sheet.
-
Remove the protective foil from the double-sided tape. (see
Figure 97
)
-
Replace the roof sheet back carefully.
-
Screw the roof sheet to the casing with the drilling screws which are intended for this purpose.
-
Close all joints between casing and roof with sealant. (
