Hydro-Pro - Heat Pump Low Pressure Switch 0.3 MPa / 0.15 MPa - 7011009

Hydro-Pro – Heat Pump Low Pressure Switch 0.3 MPa / 0.15 MPa

This is the genuine Hydro-Pro replacement low pressure switch for the Type P On/Off (P6/32) pool heat pump series. Rated to cut out at 0.3 MPa and reset at 0.15 MPa, it monitors refrigerant suction-side pressure and shuts down the compressor automatically if pressure falls to a dangerous level. Keeping this critical safety component in good working order protects the compressor from costly damage caused by low refrigerant or blockages in the refrigerant circuit.

How It Works

The low pressure switch is installed on the suction side of the refrigerant circuit, close to the compressor. If suction pressure drops below 0.3 MPa — indicating low refrigerant charge, a clogged filter drier, or restricted flow — the switch opens the control circuit and cuts compressor power before damage can occur. The compressor is allowed to restart once pressure recovers above the 0.15 MPa reset threshold, providing automatic and reliable protection without manual intervention.

Compatibility

This switch (SKU 7011009) is a factory-specified spare part for the Hydro-Pro Heat Pump Type P On/Off (P6/32), which uses R32 refrigerant. It is also confirmed compatible with the Hydro-Pro+ Premium 7, 10, 14, and 19 heat pump models. Always cross-reference your unit’s spare parts diagram before ordering to ensure the correct switch for your specific model variant.

Why Genuine Matters

A low pressure switch is a precision safety device; off-brand substitutes may have inaccurate cut-out thresholds, leading to either nuisance tripping or — more critically — failure to protect the compressor. Using the genuine Hydro-Pro part guarantees the correct pressure ratings, electrical rating, and connector fit for your unit, maintaining both warranty validity and long-term reliability of your heat pump.
