Fluidra - Compressor with Insulation Jacket for Zodiac Z400 iQ MD5 R32 Heat Pump

Fluidra – Compressor with Insulation Jacket for Zodiac Z400 iQ MD5 R32 Heat Pump

This is the genuine Fluidra replacement compressor complete with its thermal insulation jacket, designed specifically for the Zodiac Z400 iQ MD5 pool heat pump running on R32 refrigerant. The compressor is the heart of the heat pump’s refrigeration circuit, pressurising the refrigerant to transfer heat from the surrounding air into your pool water. Replacing a failed compressor with this OEM assembly restores the unit to full factory specification.

Compatibility

This compressor and jacket assembly is engineered for the Zodiac Z400 iQ MD5 R32 heat pump — a premium residential pool heat pump designed for pools up to 75 m³, featuring a rotary-vane compressor and R32 refrigerant. Always verify your heat pump’s model and serial number against Fluidra’s parts catalogue before ordering, as compressor specifications differ between the MD4, MD5, and other variants in the Z400 iQ range.

Why genuine matters

R32 is a mildly flammable refrigerant (A2L classification), which means the compressor and its surrounding insulation jacket must meet precise manufacturer tolerances for safe, leak-free operation. Using a genuine Fluidra part ensures correct refrigerant compatibility, proper electrical ratings, and preserves any remaining warranty on your heat pump. Aftermarket alternatives may not meet the exact specifications required for safe R32 system operation.

Installation

Compressor replacement on an R32 heat pump is a specialised refrigeration task that requires certified F-Gas handling qualifications. The existing R32 charge must be recovered by a qualified technician before the compressor is removed, and the system must be properly evacuated and re-charged after installation. Ensure the insulation jacket is correctly refitted around the compressor body to maintain thermal efficiency and protect against condensation.
