Plan the installation
Planning is the key of a successful installation of a central vacuum system. A
balance between the best locations for the inlet valves and the practicality of
installing in these locations is essential. With a little ingenuity, most locations can
be reached.
Hose lengths
Let customers know that you will custom the hose size to fi t each fl oor. Hose kits
come in 9 m, 12 m or 15 m lengths.
Power Unit Selection
It is important to keep in mind that air fl ow is reduced with longer hoses. To com-
pensate for the loss of air fl ow, a larger power unit is required.
Valve locations
A 50' (15.2 m) hose will usually cover between 170-220 m
