Central vacuum cleaning systems
12.
EXCESSIVELY HIGH ABSORPTION (KW)
BY HOUSEHOLD APPLIANCES
If the system does not start, if its main switch
trips or the ground fault circuit-breaker trips
(perhaps due to the simultaneous use of several
household appliances) the mains power supply
(kW) is insufficient. Switch off a household
appliance to continue working and - if necessary
- ask the utility company to increase the power
supply (kW) to your system.
13.
INSUFFICIENT OR EXCESSIVELY HIGH
SUPPLY TENSION (VOLT) OF THE MAINS
Have the tension of the mains checked, to
verify that it is not lower or does not exceed
by 5% the tension indicated on the identification
plate (see next page “Identification data plate”).
14.
DUST CONTAINER FULL
Empty the container (see page 9 “Emptying of
the dust container”).
15.
DEFECTIVE GASKET OF THE INLET
SOCKET – PROTRUDING SCREWS
Replace the gasket or tighten the screws
correctly.
16.
INSUFFICIENT DIAMETER OF SUPPLY
CABLES
If you use the model DS Super Compact 1,5
and the system does not start, check whether
the supply mains lead square measure is at
least 2.5 mm
2
.
17.
INSUFFICIENT AMPERAGE OF THE
GROUND FAULT CIRCUIT-BREAKER
If you use the model DS Super Compact 4,5
Turbo, a ground fault circuit-breaker with a FI
value of at least 300 mA is required.
1)
Models DS Super Compact 1,5 and 2,2
The main switch (with thermal safety device)
trips. Before switching it on again, wait 8-10
minutes for the motor to cool down.
2)
Model DS Super Compact 4,5 Turbo
The system turns off when the inverter
intervenes. Switch off the main switch (8) (see
page 7) on the central vacuum cleaner.
Wait one minute, then switch on the main
switch (8). Wait 8-10 minutes for the motor to
cool down.
If after completing the procedures as of items 1, 2
and 5 the thermal safety device continues to trip,
switch the system off and contact your installer.
7.
DEFECTIVE OR DIRTY MICROSWITCH OF
THE SOCKET
If the central vacuum cleaner remains switched on
or does not start despite the closing or opening of the
inlet socket, check whether the microswitch on the
socket itself works properly. If you cannot find the
cause, contact your installer.
8.
WEAR OF THE INLET SOCKET’S CONTACTS
If the system does not start and you use inlet
sockets with contacts, check whether the contacts
are worn.
9.
12 VOLT MAINS LEAD TO INLET SOCKETS
IS DAMAGED
It happens rarely that the mains lead connecting
the inlet sockets to the central vacuum cleaner
gets damaged. Contact your installer.
10.DEFECTIVE CIRCUIT BOARD – MOTOR
FAILURE
If the procedures listed above do not start the
vacuum motor, the cause lies in the burning out
of the transformer, of the relay or in a motor
failure. Contact your installer.
11. HOSE WITH ON-OFF SWITCH
If you use a hose with an on-off switch on its
handgrip and the system does not start, remains
switched on or switches on and off intermittently,
create a bridge between the two contacts (12
volt) in the socket. If the system starts, the cause
is in the hose. Contact your installer.
Clogging of the tubes – air infiltrations
DIAGNOSIS
PROGNOSIS
REMEDY
Drop in suction
power
clogged
insufficient
depression
air infiltrations
1A
Open the dust container
1B
Vacuum the other way round, connecting a powerful vacuum
cleaner to the inlet sockets
2
Explore the tubes with a spiral probe (used for
plumbing works)
3
Contact Disan’s technical office
1A
If there is no noise, switch on the system keeping
the inlet sockets closed
1B
Locate the source of whistling due to air infiltrations
2
Use the suitable inspection camera (code GE903)
