6. Maintenance
6.1 Regular maintenance
To ensure continued safe and reliable op-
eration, follow these maintenance instruc-
tions at least once every three months or
more frequently if needed:
1. Press the OK-button to perform self-
diagnostics: when the Sensor Unit is in
working order, the indicator light will
blink in green. Any other color indicates
a problem – please see section
“Troubleshooting”.
2. If there is visible dirt or grease
accumulation, 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.
6.2 Battery life and low battery
In normal use, the batteries should last 18
months.
The Sensor Unit sounds a beep with an or-
ange indication light when the battery life
is expected to run out soon (typically in a
couple of weeks). Replace the batteries
according to the following instructions.
You may reset the low battery alarm for 12
hours by pressing the OK-button.
If the batteries are not replaced, Unicook
Airis switches itself off when the batteries
are fully depleted. The PCU will also shut
down the electric power to the stove.
6.3 Battery replacement
High-capacity batteries are recommend-
ed such as Varta Industrial.
Remove the sensor unit from the mount-
ing bracket by pulling it gently.
Remove the empty batteries.
Place the new batteries in the sensor unit.
Notice the correct battery orientation
markings inside the battery compartment,
where the “+” symbol denotes the positive
terminal of the battery according to this
picture:
Place the sensor unit back onto the
mounting bracket.
