Two-storey hillside house built in the 1970s
Central unit
For this hillside house, built in the 1970s, a C 30 central unit was installed in the utility room downstairs. It was decided that the upper support structure of the row of cabinets would be utilised in the placement of the piping system, so the central unit was placed on the empty wall above the laundry basket.
Piping system
Holes were drilled through the upper cabinet for the suction and exhaust pipes. The front panel of the cabinet’s upper support structure was carefully removed so that the pipes could be installed. There was a walk-in closet located directly above the central unit on the floor above, and a hole measuring 50 mm in diameter was drilled into the intermediate floor. The dust pipe was installed in the corner of the walk-in closet, and a hole was made for a wall inlet at a height of 90 cm. Downstairs, the dust pipe was installed inside the upper support structure of the set of cabinets, where it extended to the last cabinet. Holes were made into the cabinet’s shelves, and the end of the dust pipe was led through them to the wall inlet’s installation height. The exhaust pipe was installed inside the upper support structure of the set of cabinets, extending to the partition wall and from there to the outer wall, following the wall near the ceiling. The exhaust pipe was led outside through a hole in the wall, measuring 50 mm in diameter.
Wall inlets
On both floors, a wall inlet was installed through an approximately 10 mm thick particle board wall. First, a hole measuring 50 mm in diameter was drilled through the wall for the wall inlet. The wall inlet’s elbow coupling was installed to the end of the dust pipe. The dust pipe was installed in the walk-in closet upstairs and mounted on the wall inside the cabinet downstairs. After this, a piece of a suitable length was sawn from an extension piece. Finally, the cover assembly of the wall inlet was mounted on the wall panel with screws.
