Changing the filter
Under normal operating conditions the filter in the front panel of your PARI BOY
N compressor must be replaced every 500 hours of operation or at least once a
year.
In addition, the filter must be inspected at regular intervals (after every 10th to
12th inhalation). If it is soiled (grey or brown staining) or blocked it should be
replaced immediately. If the filter has become moist it should likewise be ex-
changed for a new one.
Do not attempt to clean the filter and reuse it!
Use only the original PARI filter. Your PARI compressor could otherwise be dam-
aged or the quality of the therapy may be impaired.
Replace the filter as follows:
• Remove the filter holder from your PARI BOY N by unscrewing it in an anti-
clockwise direction with a suitable coin.
• Replace the filter and insert the filter holder into your PARI BOY N. Screw it
tight with a coin by turning in a clockwise direction.
