Zodiac - ZR 28 Three-Phase Compressor for DF 305 / DF 405 Dehumidifiers - WCO02783

Zodiac – ZR 28 Three-Phase Compressor for DF 305 / DF 405 Dehumidifiers

This is a genuine Zodiac replacement compressor — the ZR 28 three-phase unit — designed specifically for Zodiac’s DF 305 and DF 405 series built-in indoor pool dehumidifiers running on three-phase power (400 V / 3N / 50 Hz). As the heart of the refrigeration circuit, the compressor is responsible for circulating refrigerant to extract moisture from the pool hall air and maintain comfortable, controlled humidity levels. Replacing a failed or underperforming compressor with the correct genuine part restores the dehumidifier to full factory specification.

Compatibility

This compressor is confirmed for use in the Zodiac DF 305 Tri and DF 405 Tri built-in (recessed wall-mounted) dehumidifier models. It appears in Fluidra exploded views W28DF405ME, W28DF405MEB, W28DF405MEE, W28DF405MG, W28DF405MGB, and W28DF405MGE. Always cross-reference your unit’s exploded-view diagram before ordering to confirm fitment — the three-phase ZR 28 is a distinct part from the single-phase (mono) variant.

Why genuine matters

Zodiac indoor pool dehumidifiers operate continuously in demanding, humid environments. Aftermarket alternatives may differ in displacement or electrical specification, risking poor dehumidification performance or premature failure of related components.

Installation

Compressor replacement on the Zodiac DF series involves handling refrigerant under pressure and working within a three-phase electrical system. This work must be carried out by a qualified HVAC/R technician holding the appropriate F-gas certification. Ensure the system is fully recovered, evacuated, and recharged with the correct refrigerant type and quantity as specified in the unit’s service documentation before returning the dehumidifier to service.
