Hydrospin Compact Pre-Filter

Hydrospin Compact Pre-Filter

Planning the pre-filter

The Hydrospin Compact is listed as a pre-filter. AstralPool has described its Compact model as a centrifugal pre-filter; check that your selected unit matches the documented model when planning the installation.

Removing sediment before the main filter

In the documented manufacturer design, water passes through the pre-filter to separate sediment before continuing towards the main filter. Confirm suitability and operating requirements for the selected unit.

Planning space and servicing

AstralPool describes positioning its documented HydroSpin Compact between pump and filter. Check the actual unit, its connections, space and operating limits before installation. Allow access to inspect and clear collected sediment. Before opening any pressurised part, switch off and electrically isolate the connected equipment and follow the actual unit’s instructions for releasing pressure.

The HydroSpin Compact manual warns against installing it in facilities using an active-oxygen cleaning system or its derivatives, connecting it directly to the water network, and cleaning it with solvents. It also warns against using the filtration circuit to fill a swimming pool or regulate its water level. For a diatomaceous-filter installation, the manual describes a bypass between the pump and filter and closing the HydroSpin connections while diatomaceous earth is introduced. Confirm that the manual applies to the actual selected model, serial and installation before relying on these documented-model cautions.
