Fluidra - Top Plug for Zodiac Z650iQ MD8 Heat Pump

Fluidra – Top Plug for Zodiac Z650iQ MD8 Heat Pump

This is the genuine Fluidra replacement top plug for the Zodiac Z650iQ MD8 pool heat pump. It seals an upper port on the heat pump unit, maintaining the integrity of the refrigerant circuit or hydraulic assembly and preventing leaks or ingress of contaminants during normal operation and servicing.

Compatibility

This top plug is designed exclusively for the Zodiac Z650iQ MD8 heat pump — a full-inverter, energy-rated ‘A’ residential pool heat pump featuring four operating modes (Boost, Smart, Ecosilence and Smart+). Always verify your exact model variant and production year before ordering, as the Z650iQ range includes multiple sub-models with differing components.

Why Genuine Matters

Using an authentic Fluidra spare part ensures a precise fit and maintains the sealing performance the unit was engineered for. Third-party plugs may differ in thread pitch, material or dimensions, risking leaks that could compromise the refrigerant circuit or void your warranty. A genuine part also preserves the unit’s long-term reliability and energy efficiency.

Installation

Replacement of this plug should be carried out by a qualified pool heating technician or refrigeration engineer, particularly if the port is part of or adjacent to the refrigerant circuit. Ensure the heat pump is powered off and isolated before any work begins. Inspect any associated seals or O-rings at the same time and replace if worn.
