8 Routine Maintenance
8.1 Replacing the Air Inlet Filter
If the ventilator is used indoors, the condition of the air inlet filter should be checked monthly. If the
ventilator is used outdoors or in a dusty environment, the air inlet filter should be checked weekly and
replaced as necessary.
To replace the air inlet filter, proceed as follows:
1. Hold the filter between your fingers (see Figure 8-1 , item 1).
2. Remove the filter ( Figure 8-1 , item 2) and discard it.
3. Place the new filter in the device, while ensuring that:
a. The fine particle side of the filter faces outwards , away from the ventilator.
b. The filter is properly installed in its housing. Proper installation of the filter prevents particles
from entering the device.
WARNING
•
On a DAILY basis, inspect the patient circuit to ensure that it shows no signs of damage, is properly
connected, and is operating correctly without leakage.
•
Do not attempt to repair or otherwise service the ventilator yourself. Doing so might endanger the
patient, damage the ventilator, and/or void your warranty. Only qualified service personnel should
repair or service the ventilator.
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.
Caution
•
Failing to replace a dirty 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.
