Replacing the Hydrophobic Filter
NOTE: For this procedure, refer to FIGURE 3.
NOTE: Replace the hydrophobic filter when either of the following conditions occur: (1) the
filter is dirty and the aspirator has lost suction, or (2) there is liquid in the hydrophobic
filter assembly due to extended use or overflow.
NOTE: The hydrophobic filter should be replaced every two months. However, if overflow
occurs, change the filter immediately.
CAUTION
Use only Invacare recommended hydrophobic filters. DO NOT replace with
other types of bacteria filters.
1. Remove the elbow connector end of the hydrophobic filter assembly from the
top of the collection jar.
2. Separate the opposite end of the hydrophobic filter assembly from the vacuum
gauge.
3. Disassemble the hydrophobic filter assembly by disconnecting the two
connection tubes from the hydrophobic filter housing.
4. Discard the filter.
5. Re‐assemble the hydrophobic filter assembly with a new filter.
6. Re‐attach the hydrophobic filter assembly onto the collection bottle lid and
vacuum gauge.
7. If necessary, twist the elbow connector to align with the collection jar.
