Central vacuum systems
In the case of a single descent the valve with
manual closing is not necessary.
•
It is not advisable to install long horizontal lines
of diameter 80 mm and 100 mm. If on these lines
works a smaller number of simultaneous operators
than that for which it was planned some clogging
are possible.
In the cases in which the installation of these
diameters is impossible to avoid, plan in the more
distant point of the horizontal line a sweep TY in
order to be connected to an inspection cap.
•
In the big systems it’s advisable to have as many
descents as the zones or the building floors and
to connect them near the central unit. Install on
every descent a sphere valve with manual closing.
This allows, in case of assistance on a line, the
use of the rest of the system, helping any
interventions.
In the 5,5 kW models besides the inspection cap
install a by-pass valve.
The inspection cap makes easier an eventual
assistance intervention.
The by-pass valve allows the cleaning of the
piping. In this case the by-pass vale on the dust
separator must be closed in order to allow the
valve functioning on the line.
Planning of the water vacuum
system
The water vacuum is possible thanks to its special
accessory “wet pick-up” (code SZN348) to be
dragged during the cleaning, or through an
autonomous pipe line, which collects the water
into a separator (code SZN361) placed near the
central unit.
