Consider the air-flow
When you install the joints, follow the direction of
the air-flow.
The joints installed and positioned in the opposite
direction of the air-flow cause clogging and the
slowing down of the flow itself.
Central vacuum systems
•
The tubing should be installed together with or
after the plumbing system in order to avoid
changing of the route. The latter should be short
and as much as possible.
•
Unlike the plumbing system, the tubes of the
suction system do not need any slopes.
•
If obstacles are found, route and slope can be
changed.
•
The points of connection of the vertical column
and of the breather pipe to the central vacuum
cleaner are indicated in the paragraph “Location
of the central vacuum cleaner”, on page 5.
MAKING OF THE PIPING
The non-observance of the following instructions
causes clogging, a reduction in the air flow speed
and annoying whistling.
How to cut the pipes
Pipes must be cut using the pipe-cutter fitting this
purpose (e.g. the Disan pipe-cutter code GE801 for
diameters of 63 mm and pipe-cutter code GE803
for diameters up to 100 mm).
Then eliminate the slight defects inside the tube
with a little knife or with glass-paper.
Cutting the tubes with the hacksaw causes irregular
cuts and slight defects, which cause clogging.
If a secondary line is installed from the bottom to
the top, it must be inserted into the main tube on a
side or from above.
If a secondary line is installed from the bottom to
the top and is inserted into the main tube from the
bottom, the dust that flows in the tubes falls and
deposits inside the inlet valve.
