Fluidra - Replacement Compressor for Zodiac Z400 MD5 Heat Pump (Aluminium Grey)

Fluidra – Replacement Compressor for Zodiac Z400 MD5 Heat Pump (Aluminium Grey)

This is the genuine Fluidra OEM replacement compressor for the Zodiac Z400 MD5 pool heat pump in the Aluminium Grey finish. The compressor is the heart of the heat pump’s refrigeration circuit, pressurising the refrigerant gas to raise its temperature so that heat can be efficiently transferred to your pool water. Replacing a faulty compressor with an exact-match genuine part restores full heating performance and protects the rest of the refrigerant circuit.

Compatibility

This compressor is designed specifically for the Zodiac Z400 MD5 heat pump in the Aluminium Grey (AG) variant — a model built for medium-sized pools with a volume of up to 75 m³ and a rated heating output of 12.56 kW. Always verify your heat pump’s model designation and colour variant before ordering, as the Z400 range includes several size and finish options that may use different compressor specifications.

Why Genuine Matters

Using a genuine Fluidra spare part ensures the compressor is matched precisely to the R-32 refrigerant circuit, electrical characteristics, and mounting configuration of the Z400 MD5. An inferior or mismatched compressor can reduce efficiency, damage the refrigerant circuit, and void any remaining warranty on your heat pump. Genuine parts also give you the reassurance of Fluidra’s supply chain quality control.

Installation

Compressor replacement on a heat pump involves handling pressurised refrigerant (R-32) and high-voltage electrical connections. This work must be carried out by a certified F-Gas refrigeration engineer. Ensure the unit is fully isolated from both the electrical supply and the hydraulic circuit before beginning any service work.
