Compatibility and typical use
This lower plastic cover is part of the housing of Zodiac Tri salt chlorinators and is listed in the exploded view as the lower chassis cover.
It is used to rebuild or repair units where the original plastic has been damaged, discoloured or lost during previous work.
- Designed for Zodiac Tri control units that specify R0742500 as lower plastic cover.
- Suitable when refurbishing a Tri chlorinator housing after impact or UV ageing.
- Can be combined with upper covers and fixing screws to restore the full casing.
When to replace the lower plastic cover
Although the cover has no electronic function, its condition directly affects the protection and appearance of the control unit.
A damaged or missing cover leaves the electronics more exposed to moisture, dust and accidental knocks.
- Cracks, breaks or deformation in the plastic that prevent proper assembly.
- Missing sections or fixing points so the hood no longer sits firmly.
- Severe discolouration, warping or cosmetic damage to the visible casing.
- Replacement of other housing parts where a complete refurbishment is desired.
Installation guidelines
Fitting the Zodiac Tri lower plastic cover R0742500 is a straightforward mechanical task and is usually carried out together with other housing or
electronics service work. Always work with the control unit isolated from the mains supply.
- Disconnect the chlorinator from the mains before opening the housing or removing covers.
- Remove the existing lower cover and any remaining screws or clips holding it in place.
- Inspect the mounting points on the chassis and clean away dust or debris.
- Position the new lower plastic cover so that all fixing holes align with the chassis.
- Secure the cover using the specified Zodiac fixing screws, tightening evenly without over tightening.
- Check that the cover sits flush, does not move and leaves ventilation openings unobstructed.
Once installed, the new Zodiac Tri lower plastic cover R0742500 restores the mechanical protection and original finish of the chlorinator housing,
helping to safeguard the internal electronics over the long term.
