Central vacuum cleaning systems
MAINTENANCE OF YOUR
CENTRAL VACUUM CLEANING SYSTEM
1. FILTER CLOGGING
If suction power at the inlet socket is low, the filter
may be excessively clogged. You can see this
from the manometer placed on the control panel
of the central vacuum cleaner which, when the
motor is started, moves to the red area.
In this case:
if the machine has a manual shaking device,
clean it as indicated on page 8; if it equipped with
an automatic shaking device, see page 8.
2. HOSE CLOGGING
If the suction power at the inlet socket is good,
clogging is in the hose or in the brushes. If – on
the contrary - suction power at the inlet socket is
weak, clogging is
a. in the socket (visible to the naked eye)
b. in the tubing (see item 5)
If necessary, clean them manually (for precaution,
wear latex gloves, as those used in the kitchen).
3. WRONG CLOSING OF THE DUST CONTAINER
– CYCLONE’S GASKET (OPTIONAL)
DAMAGED OR OUT OF PLACE
After emptying, make sure that the dust container
closes tightly to avoid suction power reductions.
Furthermore, check that the gasket is positioned
correctly and that it is not damaged.
4.
SIMULTANEOUS USE OF SEVERAL
INLET SOCKETS
The models DS Super Compact 1,5 and DS Super
Compact 2,2 are designed for use by a single
person. The simultaneous use of several inlet
sockets on the same network entails a
considerable suction power reduction.
The model DS Super Compact 4,5 Turbo is
suitable for use by two people simultaneously.
5. TUBES CLOGGING
If the procedures listed under 1,2,3 and 4 do not
increase the air flow rate, clogging is in the tubing.
In this case, contact your installer.
6. THERMAL SAFETY DEVICE
If:
- the vacuum motor has been subjected to a
considerable electric current overload;
- the motor is defective;
- the motor has overheated due to filter clogging,
clogging of the tubing or a narrowing in the
breather pipe
