Planning of Pluggit convenience ventilation systems is uncomplicated, provided you observe a few basics. With only a few components, the plug system, flexible lines and package solutions can cover a majority of the installation.
The ground plans of the floors and a few necessary details on the construction project are required for planning. The following procedure is taken for planning:
Determination of the required flow rates
Positioning and dimensioning of components (unit, ducts, outlets etc.)
Drawing
Compilation of a material list and short calculation
Here are a few important tips:
The customer should make sure the required floor construction and breakthroughs are available. Furthermore, it may be necessary to additionally ensure sufficient insulation of the air lines. Appropriate cross section openings should be provided to ensure air flow from the supply air rooms to the exhaust air rooms. Special measures should be observed and clarified with the responsible district chimney sweep, if the installation of a solid-fuel fireplace is planned for the building.
Pre-heating (e.g. with the Pluggit SWT180 brine-earth heat exchanger) is recommended in order to operate the unit continuously also in the event of heavy frost in winter.
