VII Cleaning the Unit
Choose either of the two options below depending on the cleaning tool you
have.
If you have other pump-like cleaning tools available (e.g. for computers),
you may also utilize them. Please be careful to not exert extremes of
force or temperature / humidity onto the sensors to prevent damaging
them.
It is recommended to clean the sensors every 3-6 months for maximum
sensor functionality.
VII-1 Air Pump Cleaner
A general air pump cleaner of maximum diameter 55mm and length
150mm will be sufficient.
1. Direct the nozzle of the air pump cleaner at an opening (Figure 1 or
Figure 2) of a sensor.
2. Squeeze the bulb to blow air at the sensors.
3. Do this for 5-10 times and make sure all sensor openings are cleaned.
