Fluidra - Flow Switch for Premium Pre-filter

Fluidra – Flow Switch for Premium Pre-filter

This genuine Fluidra flow switch is a precision safety and control component designed for use with the Fluidra Premium pre-filter range. It detects the presence of adequate water flow and sends a signal to connected pool equipment — such as a heat pump or automation controller — allowing it to operate safely only when sufficient flow is confirmed. Replacing a faulty or worn flow switch restores reliable system protection and prevents dry-run damage.

Function & Safety

The flow switch acts as a guardian for your pool system: when water flow drops below the required threshold — for example, due to a blocked basket or closed valve — it interrupts the signal to downstream equipment, preventing operation under unsafe conditions. This protects costly components such as heat pump heat exchangers from overheating or running dry.

Compatibility

This flow switch is matched to the Fluidra Premium pre-filter assembly. Always verify compatibility against your pre-filter model and serial number before ordering. If you are unsure, cross-reference using your existing part number or consult the exploded-view diagram for your specific unit on the Fluidra spare parts catalogue.

Installation

Installation involves fitting the switch into the pre-filter body at the designated flow-sensing port and connecting the electrical leads to the corresponding terminals on your controller or heat pump. While the procedure is straightforward for experienced pool technicians, electrical connections should be carried out in accordance with local regulations and the equipment manufacturer’s wiring diagram.
