To cut the duct pipes, do the following:
1. Remove the EPP covers.
2. Cut the upper duct pipe (input fresh air) to the total width of the
wall (D1) - 160 mm .
Tip: Use a wide tape or two paper sheets taped together to mark the duct pipes and get a
perpendicular cut.
3. Cut the lower duct pipe (output stale air) to the total width of the
wall(s) (D2) - 125 mm .
4. Deburr the duct pipes. Use a deburring tool, such as a file.
