System temperature
The 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
above.
If this symbol is displayed the unit should be totally isolated
from the mains supply and the unit should be fully inspected
by a Domino trained technician 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 (122ºF) 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 main 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 main filter, close the front door and re
connect the mains supply.
The units’ internal temperature will be displayed on the
screen. The temperature reading will follow the traffic light
format:
• Temperature: less than 40ºC (104ºF) (GREY)
• Temperature: greater than 60ºC (140ºF) (RED)
If the temperature exceeds the alarm threshold the numeric
reading will turn red and flash to draw attention to the user,
if this temperature reaches 60 ºc the pump will shutdown
and will not restart until it the temperature is below 60 ºc
and the unit has been reset.
