iQ System Display
Heat Detection Shut off
The AD500 iQ system has an internally mounted thermal
trip. That detects the temperature in the filter
compartment. If the temperature rises above 55
o
C then the
extraction unit will automatically shut down the motor and
display the symbol below.
If this symbol is displayed the unit should be totally isolated
from the mains supply and the unit should be fully inspected
for evidence of the temperature rise. (Including inside the
Pre filter)
Once the unit is safe to turn back on and the internal
temperature has dropped below 50
o
C the thermal trip can
be reset. To do this follow the procedure below.
1.
Isolate the supply from the extractor
2. Open the front door & remove the Combined Filter
3. Locate the circular cut out in the shelf, at the front of the
unit.
4. Inside the cut out there is a small red button that can
now be pressed back in.
5. Re-fit the Combined Filter, close the front door and re
connect the mains supply.
Gas Filter monitoring (VOC Sensing)
If the VOC (Volatile Organic Compound) sensing option has
been fitted to your iQ system then this will be constantly
monitoring the exhaust gas of the extraction unit.
If the VOC level in the exhaust exceeds the PPM (Parts per
million) level pre-set at BOFA then the Gas alarm will be
triggered and display the Gas icon as shown below.
Removing the Gas alarm warning
The VOC option is a perfect way to monitor how the carbon
section of the combined filter is performing. Once the
carbon within the filter is saturated the VOC sensor will
alarm. At this point the extractor should be isolated from
the mains and a new combined filter fitted. Once a new
filter is installed the alarm will clear.
Run Safe Feature
To ensure personnel protection and avoid damage to the
unit the iQ system will automatically shut down 5 seconds
after no combined filter is detected. If no combined filter is
fitted the motor will stop and the display will appear as
below.
To resolve this, isolate the unit, fit the combined filter (see
section
6.02 ) and turn the AD500 iQ On.
