9.1
Replacing the Composite Vent Filter / Air Filter
Air is drawn into the reservoir when water is used. To maintain
water purity it is necessary to filter the air. Air-borne particles and
bacteria are removed by an air-filter. Alternatively an improved
level of water quality will be maintained within the recirculation
system using a composite vent filter, which removes air-borne
contaminants such as volatile organic compounds and carbon
dioxide.
The Composite Vent Filter/Air Filter should be replaced in the
following circumstances:
•
Six months after initial installation.
•
Reservoir overflow - indicated by incorrect reservoir
volume.
•
Quality tests indicate replacement is required.
