8. Troubleshooting (Table page 41)
1. Loose of vacuum power. If vacuum power at the inlet valves seems too weak, the first
investigation to do i sto check if the paper bag is full and proceed to ( emptying the dust
container ) and check also the HEPA filter.
2. Flexible hose is blocked. If suction at the inlet valve is correct, but not on the handle, the
flexible hose could be stopped. Usually you can solve the problem by a reverse vacuuming.
3. Blockages in the pipes. Most of the times this problem you can solve the problem by a
reverse vacuuming. After having disconnected the central unit from rigid PVC pipes try to
vacuum from the inlet valve. If the problem is not solved contact your installer.
4. Inlet valve seal damaged or not well secured. The air loss in connection with a whistling
noise by a closed inlet valve is caused by a not perfect sealing or screwing of the inlet with
pipes. Check the tightness and if needed change the joints.
5. Overheating. If the motor becomes overheated due to a chocked filter or for a blockage
in the piping, the thermostat will switch the motor off when temperature is over 90° C. It will
restart when it is cooled down, after about 8-10 minutes. If after you have excluded that a
stoppage somewhere between the motor and the handle has happened, call the customer
service
6. Safety protection. The fuse blows if the vacuum motor is exposed to an overload by main
power or if the motor is defected.
7. Motor does not turn off. If the motor does not turn off after use, ther is probably a short circuit
in the control line. Contact the Disan customer service.
8. Simultaneous use of several inlet valves. the Matrix range is conceived to be used by a
single person at the time.
