Why Genuine Matters

As a safety-critical component within the refrigerant circuit, using a genuine Fluidra part ensures the switch operates at the correct cut-out pressure for the Z650iQ MD8’s compressor. Non-genuine substitutes may have different pressure ratings, risking compressor failure or nuisance trips. A genuine part also preserves your unit warranty.
