Pre-filter

The Hydroject® aerators use a water inlet pre-filter.

The pre-filter is a "spin down, swirl type" sediment pre-filter.

The filter has a reusable polyester 100-mesh (150-micron) screen.

Screen PN 86-9140

The clear bowl allows the operator to see when the pre-filter needs to be flushed or cleaned.

NOTE:

Early units were not equipped with a pre-filter.

A kit is available to install one on older units, if water conditions warrant.

Kit Number 92-9544.

When dirt or debris accumulates in the pre-filter, the filter needs to be flushed or cleaned.

To flush the pre-filter, open the flush valve while the water is connected to the unit. This will clean the collected

debris from the bottom of the pre-filter.

NOTE:

In areas with high levels of water contamination, the flush valve can be left slightly open while

operating the Hydroject® to keep the pre-filter clean.

NOTE:

Opening the flush valve after initially connecting the supply hose will bleed air from the supply

hose.
