Hydrospin Pre-Filter

Hydrospin Pre-Filter

Planning the pre-filter

This Hydrospin pre-filter is listed for use as part of a filtration system. AstralPool has described its Hydrospin model as a centrifugal pre-filter for a pumped circuit; check that your selected unit matches the documented model when planning the installation.

Planning the water circuit

The documented manufacturer arrangement places the pre-filter between a pump and the main filter. Check how the selected unit’s connections, operating requirements and available installation space fit the complete circuit. A model name or nominal pipe size alone does not prove a suitable connection or operating range.

Access and maintenance

Allow room to inspect the selected unit and follow its actual instructions for handling collected sediment. Switch off and electrically isolate connected equipment, and follow the applicable pressure-release instructions before opening or servicing a pressurised component. Confirm which supports, valves and fittings are in the selected pack before ordering.

For the documented standard HydroSpin, the manufacturer’s manual warns against direct connection to the water supply network, use in installations with active-oxygen cleaning systems or derivatives, and solvent cleaning. It also warns against using the filtration circuit to fill a swimming pool or regulate its water level. For diatomaceous filters, that manual specifies a bypass and closing the HydroSpin connections while diatomaceous earth is introduced. Confirm the instructions applicable to the actual selected model and installation before proceeding.
