Routine Maintenance
User’s Manual 8-3
Warning
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. Replace
it when necessary—even before the recommended replacement period has elapsed, and
particularly when the ventilator is installed on the wheelchair. Environmental conditions may
cause the filter to become dirty more rapidly.
The exhalation block is intended for single use by a single patient . It may periodically be
cleaned, but it cannot be disinfected or sterilised. To maintain good measurement quality when
used continuously, clean the exhalation block periodically (refer to section
7.3, “Cleaning the
Exhalation Block” ). The exhalation block should be changed every 4 months and cannot be
reused with any other patient.
Failure to observe these recommendations may result in a loss of performance, excessive overheating, a loss of
certain functions and, in the long term, compromise the longevity of the ventilator.
Maintenance of the Internal Battery
The internal battery does not need to be removed to verify its correct operation.
Periodic Test of the Internal Battery
Your ventilator continuously and automatically checks the state of the internal battery, even when the internal
battery is not used as the main power source.
However, the battery charge status should be checked MONTHLY by disconnecting the ventilator from exter-
nal power supplies (refer to section
6, “Battery Operation.” ). Such a test is imperative after opening the venti-
lator or after a prolonged period of non-use (one month or more), in order to ensure the correct operation of
internal connections linking the battery to other components.
Warning
The maximum recommended shelf life of the internal battery is two (2) years. Do not use a
battery that has been stored for two years prior to its first use.
Periodic recharging is important to help maximise useful life of the battery. Do not store the
internal battery for extended periods, without recharging, as this may reduce the maximum
life.
Replacement of the Internal Battery
The internal battery should be replaced when the battery capacity drops below 3840 mAh. Keep in mind that,
for environmental protection, the ventilator and its components—including its internal battery—cannot be
disposed of with household waste. You must submit the ventilator and its components for suitable selective
collection and possible recycling and observe all applicable regulations.
Note:
For all additional accessories not necessarily considered as consumables consult the manufacturer’s
recommendations.
To prevent any risk of cross contamination we recommend the use of DAR™ filters (Ref: 351/5856 or
equivalent) to protect the patient outlet port and the exhalation block port.
Note:
As the total number of battery charge/discharge cycles approaches 300, a drop in potential of as much as
20% may be detected.
