Trouble-shooting
The trouble-shooting must be carried out by an authorised professional.
1.
The vacuum cleaner does not start, either with the main switch in
“MAN” or “AUTO” position.
a.
Check that there is power to the vacuum cleaner.
b.
Check that the control fuse in the electrical cabinet is not tripped. If so, reset it.
c.
Check that the motor protection is not tripped. If so, reset it.
d.
If any of the above protection or fuse are tripped again when trying to start the unit,
the probable cause can be a short circuit or the loss of one or two phases. Before a
new attempt is made, an authorised electrician must check the electrical installation,
the power supply and the vacuum pump for a possible short circuit.
2.
The vacuum cleaner only starts with the main switch in “MAN” position.
a.
Check the low voltage wiring from the machine to the vacuum outlets.
3.
The yellow lamp “FILTER” is lit (on applicable models)
a.
Take out and clean the filter. Check for damage or holes in the filter. If it is damaged,
the filter must be replaced.
4.
The red lamp “LEVEL” is lit (on application models)
a.
Change the plastic bag located in the dust container. Check also the filter and clean or
replace it accordingly. If the lamp is still lit after the bag change, the lenses at the
bottom of the cyclone need to be cleaned.
5.
Poor suction.
a.
Clean or replace the filter. If this does not help, the density of the piping system must
be checked.
6.
Unusual noise from the vacuum pump.
a.
Turn off the vacuum pump immediately and contact the supplier.
7.
The dust bag is sucked into the cyclone/filter housing.
a.
Check that the vacuum hose going from the dust container to the vacuum pump has
not come loose or been damaged. If so, tighten it or replace it with a new one.
b.
Check that the vacuum filter located in the above-mentioned hose is clean. If
necessary, clean it. Also clean the dust container.
c.
Check that the dust container fits tightly with the cyclone.
