6. Re-connect the container with the
machine being careful not to dam-
age the seal edges which would
cause a loss of suction (close both
clamps together).

7. TROUBLESHOOTING

1. fILTer IS BLOCKeD
If suction power at end of the hose is
weak check to see if waste paper bag
is full or damaged
2. flexible hose is blocked.
If suction at the inlet valve is correct,
the flexible hose could be stopped.
3. Damaged waste container not
sealed onto machine correctly
Check the condition of the waste con-
tainer and check that it is installed
onto the machine correctly, in order to
prevent loss in suction. Then close
both clamps together.
4. Several suction hoses being
used at the same time
All single phase systems are designed
for use by a single person at a time.
5. Blockages in the pipes
You should contact an official DISAN
installer.

- The vacuum motor is exposed to an
overload
- The motor becomes detective
- The carbon motor brushes become
defective or in need of replacement.
7. Micro Switch on inlet is dirty or
faulty
If the machine continues to run with
the hose removed or will not run with
the hose installed check the operation
of the micro switch on the inlet valve if
the cause is not found call the
installer.
8. Overheating
If the motor becomes overheated due
to a blocked filter or a blockage in the
pipeline the thermostat will switch the
motor off. It will restart when it has
cooled down (8-10 minutes) If after
you have followed procedures 1 and 2
it continues to overheat please call
the installer.
9. 12 volt supply is interrupted
On the rare occasion that the switch-
ing cable that connects the inlet valve
to the machine becomes faulty,
please contact the installer.
10. short circuit
If the motor will not run after checking
the previous points the problem is
likely to be a short circuit in the sys-
tem wiring and the installer should be
called in.
11. Damage to motor
or control module
If the previous procedures do not start
the system the cause is likely to be
either the transformer relay or an
internal problem with the motor and
an installer should be called.
