5.2.2 Meaning of the LED displays
5.2.2.1 Temperature LED lights up
When the "Temperature" indicator on the AirOne's control panel (membrane keypad) lights up, the unit has switched off due to over-
heating of the contact liquid. Disconnect the mains plug and allow the contact liquid to cool down for 10 minutes.
The warmer the contact medium, the sooner the unit switches off. The same also applies to extremely high outside temperatures, in
which case you should use a cooled contact medium.
Caution!
To avoid a hazard due to an unintentional reset of the protective temperature limiter, the unit must not be supplied by an external swit-
ching device such as a timer or be connected to a circuit that is regularly switched on and off by a device.
5.2.2.2 Water level LED lights up
When the "Water level indicator" lights up on the AirOne's control panel (membrane keypad), there is normally too little contact liquid
in the nebulising chamber. Switch off the unit, remove the nebulising chamber cover and nebuliser cup and replace the contact liquid.
After switching on, treatment with the AirOne can be continued. If the control indicator continues to light up, this could also be due to deposits on the sensors in the nebuli-
sing chamber. Carefully remove the deposits with a soft brush and a little vinegar-based cleaner.
If the unit still does not work after this, there is probably a technical defect and you must send it to the service centre for inspection.
Caution!
Unplug the unit from the mains before any maintenance/cleaning work.
6. Maintenance and care
6.1 Careful cleaning and disinfection
To ensure a sustained high level of treatment success, it is essential that the AirOne is carefully cleaned and disinfected after each use. Commercially available washing-up
liquid is suitable for external cleaning. For disinfection, please use the disinfectant included with the AirOne. Follow the instructions for use on the disinfectant label.
Remove the exhalation valves on the breathing mask by turning them a quarter turn to the left (bayonet catch) and remove the nebulising chamber cover on the nebuliser.
Carefully spray all components, namely the mask, valves and nebulising chamber cover. Hang up the breathing tube and spray into the tube. Please observe the information
on exposure time on the disinfectant's instructions for use. The nebuliser cup can be used again after cleaning. However, it is recommended that the cup is replaced after 3
treatments.
After the exposure time, rinse all parts with fresh water and leave to dry in a suitable place. Then reassemble all the parts and store them in the transport box provided. The
AirOne is thus perfectly prepared for the next use.
6.2 Important information about the contact liquid
Caution!
Long-term trouble-free operation is only guaranteed if the contact fluid supplied is used.
If other agents such as distilled or tap water are used as a contact medium,
the oscillator unit, the heart of the unit, will be
permanently damaged
and the unit will then have to be repaired and all warranty claims will be invalidated. The contact
agent is produced in the laboratory with a conductivity specially adapted to the AirOne. If this is not or no longer correct, the water level indicator lights up.
The contact liquid is only renewed when the water level indicator lights up or there is visual contamination. If the AirOne is not used for more than a week, please remo-
ve the contact fluid and only refill the AirOne when it is used again.
6.3 Further care instructions
Caution!
Do not carry out any descaling activities. These permanently damage the surface at the bottom of the nebulising chamber (ultrasonic oscillator / transducer)
and it will need to be replaced. Never touch or clean the oscillator with a hard object. Do not use acidic cleaning agents.
For optimal care of the nebulising cham-
ber, take a soft brush, pour water without additives into the nebulising chamber and use the brush to swirl up any possible residue and then rinse it out
.
You can wipe the housing with a damp cloth and then rub it dry
.
