Replacing the Air Inlet Filter

Warning
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If
necessary, replace the filter before the recommended replacement period is over. This is
particularly important when the ventilator is installed on a wheelchair, because environmental
conditions may cause the filter to become dirty more rapidly.
Failing to replace a dirty air inlet filter, or operating the ventilator without a filter, may cause
serious damage to the ventilator.
The air inlet filter is not reusable; do not attempt to wash, clean, or reuse it.
If the ventilator is used indoors, the condition of the air inlet filter should be checked monthly. If the ventilator
