MAINTENANCE

spirodoc requires very little maintenance. The only periodic requirements are:
• Cleaning and general control of the turbine flow and volume measuring system.
• Periodic changing of the operating battery.
4.1 Cleaning and general control of the turbine
The turbine flow and volume measurement system used by the spirodoc guarantees accurate measurement and also
has the major advantage of not requiring any periodic calibration. In order to ensure the correct operation of the turbine it
is necessary to carry out a simple cleaning. This operation also assures a level of hygiene for the subjects who will
breath through the machine.
WARNING
It is a good rule to make a visual check from time to time that dirt or foreign bodies are not deposited inside the
turbine, like hair for instance. Any such deposit could slow or block the free movement of the turbine blade and
thus compromise the measurement accuracy.
To clean the turbine first remove it from the machine by rotating it and then pulling it gently, holding it by the mouthpiece.
It can help to push it gently with a finger from underneath.
Immerse the turbine in a detergent solution (not hot), and move it in the liquid in order to remove any impurities
deposited. Then rinse the turbine immersing it in clean water (not hot).
WARNING
To avoid permanent damage do not put the turbine under a direct jet of water or other liquid. If no detergent
solution is available it is necessary to clean the turbine in clean water.
Leave it to soak for at least one hour. Shake off the excess water from the turbine and leave it to dry standing it vertically
on a drying surface.
To check the perfect functioning of the turbine, before reinserting it inside the machine it is good practise to make a
visual check that the mobile part moves freely. Place the turbine horizontally and move it slowly from side to side, the
mobile part (blade) must move without any obstruction. If this is not the case, the accuracy of measurement is no longer
guaranteed and the turbine must be replaced.
When the turbine is clean replace it in the spirodoc note the correct direction as indicated by the "arrow" ( ) printed on
the spirodoc case. Twist to lock the turbine into the case.
WARNING
To insert the turbine correctly into the machine, push it inside and turn it anticlockwise until you hear a "click"
which confirms that the turbine is locked inside the plastic case.
4.2 Replacement tape instructions
The adhesive tape is made from latex-free materials. It is recommended to use a new sensor tape for each new patient
or as needed.
• Genly remove used sensor tape and discard appropriately.
• It is recommended to use a new sensor tape for each new patient or as needed
• Sensor back is equipped with alignment pegs. Place sensor with alignment pegs down against adhesive side of tape,
aligning the pegs with the tape holes properly
• Press firmly on sensor to push pegs through tape holes. Pick up both sensor and tape and verify sensor pegs are
aligned properly.
4.3 Changing the battery
When ' ' BATTERY LOW' ' appears on the display of the spirodoc at switch on, or if the machine does not switch on at all,
then change the operating battery.
WARNING
Only use 3V Lithium battery CR123A or equivalent.
When you insert the battery pay close attention to the
polarity +/- shown inside the battery cover (see design
below)
