Zodiac – GenSalt OT white bottom cover – R0839400

The Zodiac GenSalt OT white bottom cover (R0839400) is an original manufacturer replacement part designed specifically for the GenSalt OT salt chlorinator range. This lower housing cover forms part of the protective enclosure of the GenSalt OT electrolysis unit, shielding the internal components from moisture, debris, and environmental exposure. As a genuine Zodiac spare part, it ensures a precise fit and maintains the structural integrity and weatherproofing of the chlorinator housing.

The bottom cover is finished in white, matching the standard aesthetic of the GenSalt OT unit. Replacement of this component is necessary when the original cover becomes cracked, warped, discoloured, or damaged through UV exposure or physical impact over time. Using an original OEM part guarantees compatibility and preserves the correct IP rating and sealing performance of the overall assembly.

Technical details and compatibility

This bottom cover is manufactured by Zodiac and carries part reference R0839400. It is designed for use with the GenSalt OT salt chlorination system, a popular automatic chlorinator used in residential swimming pools. The GenSalt OT series is known for its ease of use and reliable electrolytic chlorine generation. This replacement cover fits the standard GenSalt OT housing configuration. According to available product listings, the part is also referenced as compatible with other closely related GenSalt OT model variants — check your unit’s model label before ordering to confirm suitability.

The cover is constructed from UV-resistant polymer, typical of outdoor pool equipment housings, and is designed to withstand continuous exposure to pool-side environments including humidity, sunlight, and chemical vapour. Installation requires no specialist tools and is a straightforward panel replacement task suitable for a competent DIY installer or pool technician.

Suitability and application

This part is intended exclusively as a replacement component for owners of the Zodiac GenSalt OT salt chlorinator who need to restore the physical housing of their unit.
