Zodiac – EXO white upper housing cover – R0823400

The Zodiac R0823400 is the white upper housing cover (capot supérieur) designed as a genuine OEM replacement part for the Zodiac EXO series salt chlorinator units. The upper cover forms the external top shell of the chlorinator control head, protecting the internal electronics, display, and PCB components from water ingress, UV exposure, and environmental wear. As a structural outer component, it plays a direct role in maintaining the integrity and weatherproofing of the entire chlorination unit.

This cover is finished in white and is engineered to fit precisely onto the EXO chlorinator body, ensuring that all internal assembly points, cable routing, and locking features align correctly with the base unit. It is manufactured from UV-stabilised polymer material appropriate for outdoor poolside environments where prolonged sun and heat exposure is expected. The part is supplied individually and is intended as a direct like-for-like replacement for a damaged, cracked, or discoloured original cover.

Compatibility and technical context

The R0823400 upper housing cover is compatible with the Zodiac EXO, EXO iQ, and EXO iQ LS salt electrolysis chlorinator range. The EXO series is a widely installed residential and semi-commercial salt chlorinator line produced by Zodiac Pool Systems, covering pool volumes typically from around 30 m³ up to larger installations depending on the specific model variant. The cover is not a universal part and must only be used on EXO series units — it is not interchangeable with other Zodiac product families such as the Tri-Expert or Clear range. Always verify the exact model of your chlorinator before ordering.

Installation involves removing the existing upper cover by releasing the retaining fixings on the EXO base unit and fitting the replacement part by reversing the disassembly process. No specialist tools are required for the swap, though it is recommended that the chlorinator is powered down and isolated before any work is carried out on the housing.

Suitability and buying guidance

This part is the correct choice for owners of Zodiac EXO, EXO iQ, or EXO iQ LS chlorinators whose upper housing has become physically damaged, UV-yellowed, cracked from impact, or otherwise compromised. Replacing the cover restores the weatherproof protection of the internal electronics and ensures the unit continues to operate safely in an outdoor pool environment. Because this is a genuine Zodiac spare part carrying the original part number R0823400, it guarantees dimensional and material compatibility with your existing unit. It is not suitable for use as a standalone accessory or with any non-EXO Zodiac chlorinator model.
