c
Caution:
Mount the wall duct carefully, and provide for proper
sealing. Otherwise draught and condensation problems
may occur, affecting the operation of the fan coil unit.
1. Apply expanding foam gasket (included) around the unit's
ventilation opening (the shaded area in the figure).
2. Make an opening through the wall (see Table 2-1 for
dimensions).
3. Fix the duct sections as you please, e.g., by bricking them
in or by fixing them with screws. In doing so, note the
positions of the screws: these must not hinder the installa-
tion of the grate.
4. Carefully seal all seams and cracks with a sealant.
5. On the flanges of the duct section that is fixed to the outer
wall: drill through the grate holes using a Ø 5 mm drill.
6. Apply sealant to the inner side of the grate flanges, pro-
perly sealing the gap between grate and duct.
7. Mount the grate to the flanges using sheet metal screws.
n
Note:
In doing so, note the correct position of the blades: these
should be oriented outward to allow for run-off.
8. Finish the wall duct in a draught-proof manner.
