Safety functions

Tilt and vibration protection

• If the appliance is placed inclined more than 15°, or tilts/vibrates too much due to a defect or incorrect placement, the appliance will immediately stop the filtration.
• The power indicator and the filter indicator flash and a continuous acoustic signal sounds.

Acoustic signal
At the end of each filtration cycle, an acoustic signal sounds for 5 seconds. The appliance also beeps if any error occurs. The acoustic signal can be deactivated (see chapter “Getting started”).
Over-temperature

• In case of overheating (control unit >75°C), the appliance will stop the filtration process.
• The power indicator (1) flashes.
• Remove the appliance from the fryer and store it (see chapter “Storage / cooling time”).

Getting started

Filtration time
The factory setting of the filtration time is 4 min. 30 sec. Up to 4 filtration cycles are possible directly one after the other.

1. Wait until the filter indicator lights up briefly and a short acoustic signal sounds.

2. Press Start / Stop button to adjust the signal.

3. The LEDs show the status:
   Power indicator = Sound off
   Filter indicator = Half volume
   Power indicator + filter indicator = Sound on
