6. Using the Stove
Guard
6.1 Cooking Safety
Unicook Airis monitors the stove
area and improves cooking safety by
sounding an alarm and switching o the
cooker power if it detects a potentially
dangerous cooking situation. These
situations may be, for example, an
overheating pan or prolonged lack of
human presence during cooking.
When you hear the alarm:
1. Check the situation calmly. If there
is no danger, you can prevent the
cooker power from being switched
o by pressing the OK button ❸
during the alarm and continuing to
cook.
2. If you do not press the OK button ❸
in 15 seconds, the stove guard will
switch o the cooker and the oven:
after switching o, a repetitive signal
will sound and the indicator light ❹
will lash red for 15 minutes.
3. When there is no more danger, you
can return the power to the cooker
and oven by pressing the OK button
❸. First, turn the hob switches to the
o position.
4. Ensure that the hazardous situation
will not reoccur.
WARNING
Please note that not all possible
hazards may be detected. Also note
the limitations in chapters 12 and 13 .
6.2 Remote alarm
With Airis Sense Wi-Fi, you may activate
the remote alarms by setting up a Wi-Fi
connection via Safera App (see chapter
5.1 how to connect the Safera App) and
creating a Safera Cloud account which
allows you to set up the remote alarm
settings.
6.3 Smart Cooking
By connecting the Safera App (iOS),
you may use the smart cooking features
which assist you in cooking with
automated timers and temperature
assistant. Install the Safera App

7. Maintenance
7.1 Regular maintenance
To ensure continued safe and reliable
operation, follow these maintenance
instructions at least once every 12
months or more frequently if needed:
1. Press the OK button ❸to perform
self-diagnostics: when the sensor unit
Ⓐis in working order, the indicator
light ❹will lash in green. Any other
color indicates a problem – please see
chapter 9 Troubleshooting.
2. If there is visible dirt or grease in the
sensor unit Ⓐ, wipe the sensor unit
with a soft cloth moistened with
water or a mild detergent, such as
washing up liquid. Avoid pressing the
appliance buttons and sensors ❺.
3. It’s highly recommended to always
have the latest irmware version of
the sensor unit Ⓐinstalled, so check
that your Safera App and the device
irmware is up to date (see chapter
5.2).
7.2 Battery life and low battery
In normal use, the batteries should last
between 2 to 3 years (Airis Sense) and 1
to 2 years (Airis Sense Wi-Fi). Frequent
usage of the sensors and the Bluetooth
connection with the smartphone app
and a low quality wii-connection will
tend to decrease battery lifetime.
The sensor unit Ⓐbeeps and the
indicator light ❹lashes red when the
batteries are depleting (typically within
2 weeks of expiration). Replace the
batteries according to the following
instructions.
You may reset the low battery alarm for
12 hours by pressing the OK button ❸.
If the batteries are not replaced,
Unicook Airis switches itself o when
the batteries are fully depleted. If the
system is equipped with the power
control unit Ⓑ, it will also shut down the
electric power to the stove.
7.3 Battery replacement
1. Open the sensor unit Ⓐby pushing
the cover lock on the side gently with
a lat headed screw driver and pulling
o the sensor unit Ⓐfrom the bracket.
2. Place three AA/LR6 Alkaline batteries
in the sensor unit Ⓐand six batteries
in the power bracket Ⓒ. Notice
the battery polarity marked on the
sensor unit and on the bracket.
3. Place the sensor unit Ⓐover the
power bracket Ⓒso that the cover
locks snaps into their places on both
sides.
