Central vacuum cleaner for existing buildings

Supplies

A 30 central unit, PPK 44 pipe kit, PPL 44 pipe kit, surface installation case for the wall inlet, silencer for exhaust air, and cleaning equipment

Central unit

The heated basement was selected as the location of the central unit in this wooden house built in the 50s. The basement is classified as storage space, and not used for living, so the inexpensive A 30 model could be used. The central unit was installed to the right of the stairs in the parting wall of the basement, close to a wall socket. This also shortens the distance the exhaust pipe has to run from the central unit.

Piping

It was decided that the paneled wall of the staircase should be utilised in the positioning of the pipes. On the first floor, the two outermost panels were detached on the side of the stairs, and a space was sawed for the pipe in the studwork of the wall. A hole was drilled through the wall for the first floor wall inlet. After installing the pipes, the wall panels were nailed back up, resulting in hiding the dust pipe. The basement walls were cast concrete, which made it necessary to surface install the dust pipes. A hole was drilled on the exterior wall for the exhaust pipe of the vacuum cleaner, and the blow-out vent cap was attached from the outside, which gave a neat and functional end result. On the second floor, the dust pipe ended in the attic space between the exterior wall and the habitable rooms, and was extended to the wall of the attic room. A hole for the wall inlet was drilled at 90 cm from the floor. After installation, the pipe remaining in the unheated space was insulated with a 50 mm wool insulator.

Wall inlets

The installation of the pipes utilised the wall next to the stairs. The stairs were situated almost in the middle of the house, which meant that the entire building could be cleaned using an 8 metre suction hose, installing only one wall inlet on the same wall on each floor. For the surface installed wall inlet in the basement, a surface installation case was acquired.

Supplies

C 30 central unit, C series wall bracket, mounting for the wall bracket, PPL 44 pipe kit, 4 dust pipes 1.2 m long, silencer for exhaust air, blow-out vent cap, and cleaning equipment

Central unit

This house is a small gabled house built in the 60s. There were no separate storage spaces in the house, so the central unit was installed in the habitable space. A good place was found in the cleaning cupboard in the lobby. The location suggested using a central unit from the quiet C series, and the user selected the C 30 model.

Piping

The suction pipe was installed inside the cupboard. From the wall bracket of the central unit, we first went downwards, and then brought the end of the suction pipe to the wall inlet on the wall of the cupboard at the height of 70 cm, using a 90° angle. A 50 mm hole was drilled for the exhaust pipe to the roof through the upper part of the cupboard and the ceiling structures. The exhaust pipe was installed to the roof beneath an approximately 50 mm thick wool insulator. A silencer was also installed on the exhaust pipe on the roof. The end of the exhaust pipe was drawn to the gable of the building, and the blow-out vent cap was also installed here.

Wall inlets 

The cupboard was located on a central place in the house, which meant that only one wall inlet was needed. It could be installed on the wall of the same cupboard the central unit was installed in. A 75 mm hole was made on the wall for the mounting bracket, and eventually, the wall inlet cover assembly was screwed onto the mounting bracket from the outside.

Other things to note

Finally, cooling air holes were made on the cupboard according to the instructions. At the bottom, a 30 mm-deep strip was sawn off from the edge of the shelf for the entire width of the door opening, and similar holes were made above the central unit. This enables the air heated by the central unit to flow out of the cupboard. Before commissioning the vacuum cleaner, an electrician installed the necessary wall socket to the cupboard, fitted with a 10 A delay fuse.

Supplies

C 30 central unit, PPC 44 pipe kit, mounting for wall bracket, silencer for exhaust air, and cleaning equipment.

Central unit

In this hillside building from the 70s, a C 30 central unit was installed in the utility room downstairs. The pipes were installed in the upper socle of the cupboards, and for this reason, the central unit was installed on the free wall above the laundry basket.

Piping

Holes for the suction and exhaust pipes were drilled through the uppermost cupboard. The front board of the upper socle was removed carefully to enable the installation of the pipes. A 50 mm hole was made to the intermediate floor in the wardrobe directly above. There, the dust pipe was installed in the corner, and a hole for the wall inlet was made at 90 cm from the floor. Downstairs, the dust pipe was installed to the upper socle of the last cupboard in the row, and the end of the dust pipe was brought level with the wall inlet installation height through holes made in the shelves. The exhaust pipe was installed in the upper socle through to the parting wall, and from there to the exterior wall next to the ceiling. The exhaust pipe was drawn out through a 50 mm hole made in the wall.

Wall inlets

The wall inlets on both floors were installed through a chipboard wall approximately 10 cm thick. A 50 mm hole was first drilled through the wall for the wall inlet. The elbow coupling of the wall inlet was installed at the end of the dust pipe, and then the pipes were attached to a wall inside the wardrobe upstairs, and a wall inside the cupboard downstairs. A suitable piece of the extension was sawn off, and finally, the cover assembly of the wall inlet was screwed to the wall panel.

Supplies

A 30 central unit, PPK 44 pipe kit, silencer for exhaust air, extension, and cleaning equipment

Central unit

This house had a spacious storage room, so the A 30 central unit was installed there. The mounting hook for the central unit was installed on the wall approximately 120 cm from the ground.

Piping

A hole was drilled for the dust pipe from the attic space upstairs to the storage room. In the storage room, the pipe was surface installed to the vacuum cleaner, and the exhaust air pipe was lead outside through the external wall. A silencer for exhaust air, acquired separately, was installed on the exhaust pipe. The upstairs wall inlet was installed next to the attic door. For the downstairs wall inlet, 3 metres of dust pipe were installed by the attic floor, and in the attic, a hole was drilled through to the wardrobe downstairs. The dust pipe was installed inside the wardrobe, and the end of the pipe was drawn next to the floor to the wall inlet.

Wall inlets

Both wall inlets were installed on a chipboard wall by attaching the cover assembly of the wall inlet to the wall panel, and connecting the cover assembly to the pipes with an extension. The dust pipe and the elbow coupling of the wall inlet were attached on the opposite side of the wall. The attic wall upstairs had such a thick structure due to the thermal insulation material, that two extensions were needed.

Supplies

C 30 central unit and cleaning equipment, PPC 44 pipe kit, mounting for wall bracket, and silencer for exhaust air

Central unit

In this two-storey terraced house from the 80s, the C 30 central unit was installed by the entrance. The wall bracket was attached above the shoe rack with the mounting for the wall bracket.

Piping 

The exhaust air pipe was installed upwards from the central unit, and drawn out through the outer wall following the ceiling. The blow-out vent cap was installed on the left side of the main door, under the roof. The exhaust air silencer was installed by the roof inside the wall. A 50 mm hole for the suction pipe was made on the upper part of the parting wall, leading to the upper socle of the cupboards in the hall. A pipe for the downstairs wall inlet was installed to the socle of the last cupboard in the row, and then lead through holes made in the upper cupboard to the lower cupboard. The wall inlet was installed through the parting wall at approximately 90 cm from the floor in the living room.

In order to install the upstairs wall inlet, the bottom plate of the cupboard in the bedroom was removed, to enable making a hole for the dust pipe in the multicore slab intermediate floor. The upstairs cupboard was directly above the downstairs cupboards, which enabled branching the dust pipe in the upper socle of the downstairs cupboard. The dust pipe for the wall inlet was attached on the inside wall of the cupboard upstairs, and a 50 mm hole was made for the wall inlet in the parting wall at the same height with the light switch. The pipe was lead through the wall using an extension, and the cover assembly was attached to the wall panel using a plasterboard clamp.

Wall inlets

In this house, both wall inlets were installed by attaching the dust pipe and the elbow coupling of the wall inlet on the opposite side of the wall, and installing the cover assembly of the wall inlet on the other side of the wall. A suitable piece was cut from the extension for leading the pipe through. When attaching to a plasterboard, suitable clamps should be used and drilled fast before making the 50 mm hole in the wall. This reduces the risk of splits in the board.

Supplies

C 30 central unit, C series wall bracket, mountings for the wall bracket, PPL 44 pipe kit, four dust pipes 1.2 m long, blow-out vent cap, silencer for exhaust air, and cleaning equipment

Central unit

The silent C series central units are usually used for detached houses, as was in this house. The entrance was quite narrow, so the central unit was installed in the cleaning cupboard. The wall bracket of the central unit was installed using mountings to the back wall of the cupboard, and the supports for the central unit were attached to the bracket. After installing the piping, the central unit could be lifted to the bracket. A wall socket was installed by a professional next to the unit.

Piping

As this house had a gable roof, and the building only had one floor, it was easiest to install the piping in the roof. This also enabled installing the wall inlet on a central place in the apartment. 50 mm holes were drilled for the suction and exhaust pipes through the upper cupboard to the roof. Inside the roof, insulations were removed from above the parting wall in order to view the upper part of the parting wall where the wall inlet would be. A hole was made to the wood to fit the dust pipe. The elbow coupling was pushed inside the dust pipe leading to the wall inlet, and the low voltage lead was attached to the dust pipe. The dust pipe was pushed inside the parting wall, until the elbow coupling of the wall inlet was level with the hole made for the wall inlet. The suction pipe was installed from the roof to the central unit wall bracket, and the exhaust pipe was installed through the roof to the outer wall beneath the eaves. A silencer was installed to the exhaust air pipe on the attic. Finally, the blow-out vent cap was attached to the exterior wall beneath the eaves.

Wall inlets

The roof allowed the dust pipe access to a central location in the apartment, so only one wall inlet was required for the cleaning of this apartment. The parting wall was made of plasterboard, so plasterboard clamps were drilled to the wall where the mounting holes for the wall inlet would be. Only after this, a 50 mm hole was drilled to the wall for the wall inlet. Once the dust pipe had been installed inside the parting wall, a suitable piece was cut from the extension to support the elbow coupling of the wall inlet to the back panel of the wall. Then the low voltage leads were connected to the wall inlet, and the cover assembly of the inlet was screwed onto the clamps.

Other things to note

Cooling air holes were finally made according to the instructions to the cupboard where the central unit was installed.
