Description
Zodiac control unit protection cover R0741800
The Zodiac control unit protection cover R0741800 is the original front protective hood for Zodiac Tri, Tri Expert and Hydroxinator control units.
It shields the lower part of the electronics housing from dust, splashes and accidental knocks, helping to preserve both the safety and appearance
of the salt chlorinator in the technical room.
Main features of the Zodiac protection cover
- Original Zodiac protection cover for the control unit front section.
- Designed for Tri, Tri Expert and Hydroxinator salt chlorinators.
- Accurately moulded to match the original housing shape and fixing points.
- Improves mechanical protection for the internal electronics and wiring.
Compatibility and applications
The R0741800 protection cover appears in the official spare parts diagrams for multiple Tri and Hydroxinator models as “capó de protección de la unidad de control”.
It is used together with the lower plastic cover and upper chassis cover to complete the housing around the control electronics.
- Compatible with Zodiac Tri salt chlorinators listed under Tri and Tri Expert reference ranges.
- Used on Tri Expert and Tri Expert LS models that share the same control housing design.
- Also fitted on Hydroxinator and Hydroxinator MagnaPool units that specify R0741800 in their parts list.
If the exploded view for your chlorinator shows R0741800 as the control unit protection cover, this spare part is the correct replacement.
When to replace the control unit protection cover
The protection cover is exposed to daily handling, chemical vapours and possible impacts in the plant room. Over time this can cause damage or
strong cosmetic wear that justifies replacement.
- Cracks, breaks or missing pieces in the plastic hood.
- Broken fixing points so the cover no longer clips or screws into place correctly.
- Heavy discolouration, warping or deterioration due to UV or chemicals.
- Refurbishment of an older Tri or Hydroxinator unit where a fresh housing is desired.
Installation guidelines
Fitting the Zodiac control unit protection cover R0741800 is a mechanical operation that can be done during normal maintenance, always with the
control unit isolated from the mains supply.
- Disconnect the chlorinator from the mains before working on the housing.
- Remove the damaged protection cover along with any associated screws or clips.
- Inspect the chassis and adjacent covers, cleaning dust and debris from the mounting area.
- Position the new R0741800 cover so that all fixing points align correctly with the chassis and lower cover.
- Secure the cover using the specified Zodiac screws or clips, tightening evenly without deforming the plastic.
- Check that the cover sits flush, moves slightly only where designed and leaves ventilation openings unobstructed.
Once installed, the new Zodiac control unit protection cover restores the mechanical shielding and clean appearance of the Tri, Tri Expert or
Hydroxinator control unit, contributing to long term protection of the electronics.
