CONTROL LEDS
Two control LEDs (“DL1” and “DL2”) are provided on
board the circuit board.
• DL1 stays on steadily if no sensor or engine problems
are detected:
- DL1 flashes if one or both relative humidity sensors
are not connected or if they give communication
errors at (0.5s ON and 0.5s OFF).
- DL1 also flashes due to motor error at
(1s ON and 1s OFF).
- DL1 also flashes due to overcurrent error at
(0.05s ON and 0.1s OFF).
• DL2 flashes proportionally to the speed:
- Vmax at (0,25s ON and 0,25s OFF)
- Vmed at (0,5s ON and 0,5s OFF)
- Vmin at (0,1s ON and 0,9s OFF)
MAINTENANCE/CLEANING
Proceed as follows to check if the appliance needs
cleaning:
• disconnect the appliance from the mains;
• remove any blanking caps from vents that are not
connected to intake ducts so that you can see inside
the appliance and see the blades;
• check the blades for dust: A thin layer of dust will not
affect performance but, if the layer is more than 1 mm
deep, the blades should be cleaned;
• check the motor bearings by spinning the blades:
bearings in good condition make no noise; Rotating
the blades manually a few times, their movement is
jerky and they come to a stop. This behaviour is
known as “clogging” and is typical of units powered
by motors with permanent magnets like those fitted
to the Vort Leto Mev;
• on completion of the cleaning, reposition the blanking
caps where they were beforehand;
• reconnect the appliance to the mains;
Vents should be cleaned regularly to ensure that the
unit is working at its best and that the areas involved
are being well ventilated. Make sure that system
settings are not interfered with. Each vent should be
repositioned exactly as it was beforehand. Vents with
no filter can be removed from the mouth of the duct.
Any insulation foam (if present), should be removed
before cleaning the vent with warm water and liquid
detergent. Replace the vents after cleaning.
