Puritan Bennett 560 Ventilator User's Manual - Covidien

8 Routine Maintenance
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 open, repair or otherwise service the ventilator yourself. Doing so might
endanger the patient, damage the ventilator, and/or void your warranty. Only personnel
authorised and qualified by Covidien should repair, open or service the ventilator.
8.1 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
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:
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.
