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
fl
exible hose
could be stopped.
3. Damaged waste container not sealed onto machine correctly.
Check the condi-
tion of the waste container 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 of
fi
cial DISAN installer.
6. Safety protection.
The 10 Amp fuse will quickly blow if - The vacuum motor is expo-
sed 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
fi
lter 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 over-
heat please call the installer.
9. 12 volt supply is interrupted.
On the rare occasion that the switching 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 system 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.
12. Hose with on/off switch is defective.
If you are using a system with a
fl
exible
pipe containing an on/off switch and you experience problems such as the machine
switching on and off intermittently or it will not start or switch off you should contact the
installer.
13. Low power in the house.
If the system fails to start and trips the main switch in
the house it could be that there are too many appliances using the electricity. To rectify,
switch off any non essential appliances.
14. Voltage supply too high or low.
Do not use the machine if the household voltage
varies by more than 5 % than that stated on the identi
fi
cation plate.
