Application and selection notes

Check minimum specific gravity, temperature, contacts and cable material for the selected float code; do not combine limits from different versions.
400 kPa at 20°C is a stated test condition, not a continuous operating-pressure rating.
Allow free float travel, avoid inlet turbulence and cable entanglement, and keep the junction box dry.
