N.B.
• The installer is responsible for connecting optional
safety devices that automatically turn the appliance
OFF when the inspection panel is opened. The
installation of micro-switches, like any other
electrical safety device fitted, must completely stop
the appliance from operating. Should this happen,
the power supply to appliance can only be restored
by manually turning the appliance switch back ON
and by returning power to it from the mains board.
• The earth connection must be made using the
special terminals inside the appliance and in
complete
accordance
with
current
legal
requirements.
Earthing the appliance is an absolutely essential to
comply with the safety standards aimed at
preventing electrical accidents.
If the appliance is not earthed or is improperly
earthed, the manufacturer will not be held
responsible for any harm or damages caused by an
electrical accident.
• The installer is responsible for activating any safety
devices on the appliance in accordance with the EC
Machinery Directive.
• All the wiring and electrical components used in the
installation must comply with current European and
local legal requirements.
Signs on the appliance
A number of signs may be present on the appliance
and these must never be removed (Fig 11).
These signs may be:
• danger and information signs;
• danger signs;
• identification marks;
• prohibition symbols; (only for VORT QBK POWER
models)
Start-up procedure:
• Make sure that there are no foreign bodies or dirt
near the fan blades.
• Check that the air inlet and outlets are clear.
• Make sure that the safety systems are reliable and
working properly by repeatedly testing them to
ensure they turn the appliance OFF and that the
power supply is disconnected. We recommend that
you test that the system is working properly at least
three times.
• Check that the pulley is properly aligned and
securely fixed on the shaft (QBK POWER).
• Make sure that the fan blades turn in the same
direction as shown by the arrow on the side of the
shield.
• Run the appliance for 120-180 minutes then check
the belt drive tension. If it needs adjusting, follow the
procedure described later (QBK POWER).
• Measure the power absorption and compare it with
the data on the ID plate. If it is higher, trace the
cause by checking that:
- the motor and fan blades can rotate freely;
- the fan speed is as it should be;
- airflow is not higher than the appliance nominal
value;
- the power supply is correct.
• Make sure that any shielding protecting moving
parts is properly fitted in place.
• Check that the filter has not been damaged during
transport or handling and that it is intact and clean.
Maintenance
Apart from observing legal requirements relating to
accident prevention, maintenance staff must also
make sure they are wearing suitable PPE and using
ear protectors if noise emissions exceed the permitted
levels.
Safety systems
The safety systems required to comply with the EC
Machinery Directive relating to this appliance must be
tested at least once every 90 days.
The test must conform that the safety systems fitted
are working properly and are reliable.
To perform a valid test:
1. using the documents supplied with the appliance,
find out what safety devices and construction
adaptations apply
2. take all the necessary precautions and, when the
appliance is operating normally, cause the safety
systems to cut in one at a time. Make sure that the
power supply to the appliance cuts out and that all
moving parts come to a stop (by opening the
inspection panel); repeat this operation twice but
not consecutively with all the safety devices fitted to
the appliance.
3. check that the static and passive safety systems are
properly positioned and fastened in place; check
especially that shields protecting moving parts are
properly fastened in place and can only be removed
using special tools.
