Description
Zodiac empty cell body R0740200
The Zodiac empty cell body R0740200 is the original transparent housing for Zodiac salt chlorinator electrodes. It provides the hydraulic chamber,
unions and mounting points for the electrode, O-rings and tightening ring, so you can rebuild a worn or damaged cell while keeping the original
dimensions and flow characteristics.
Main features of the Zodiac empty cell body
- Original clear cell housing without electrode for Zodiac salt chlorinators.
- Includes the transparent body section with integrated inlet and outlet connections.
- Designed to accept the original electrode, sealing O-rings and tightening ring.
- Maintains correct internal geometry for optimal water flow through the cell.
Function and role in the chlorination system
The cell body is the part of the salt chlorinator where electrolysis takes place. Water flows through the transparent housing, around the electrode
plates, where chlorine is generated from the dissolved salt. A sound, undamaged body is essential for correct flow, safe pressure resistance and
easy visual inspection of the cell during operation.
By replacing a cracked or opaque housing with the original Zodiac empty cell body R0740200, you restore the mechanical integrity of the cell and
recover full visibility of the electrode and water flow.
Compatibility and typical applications
The R0740200 empty cell body is used on Zodiac salt chlorinators that share this specific clear housing design. It is the correct spare when the
exploded view for your model lists R0740200 as “cuerpo de célula vacía” or “empty cell body”.
- Designed for selected Zodiac Tri and Tri Expert salt chlorinators.
- Used on compatible Hydroxinator MagnaPool units that share the same clear cell housing.
- Suitable when rebuilding a cell using the existing compatible electrode, O-rings and tightening ring.
Always check the reference on the original body and the parts diagram of your chlorinator to confirm that R0740200 is specified for your model.
When to replace the cell body
Although the cell body has no electrical parts, its condition directly affects safety, sealing and ease of maintenance. Over time, exposure to
pressure, chemicals and UV can damage or degrade the plastic.
- Visible cracks, crazing or leaks on the transparent housing.
- Deformed connections or union seats that no longer seal correctly.
- Strong loss of transparency, making it difficult to inspect the electrode and detect scale.
- Damage from overtightening unions, freezing or accidental impact in the technical room.
Installation guidelines
Replacing the Zodiac empty cell body R0740200 is a plumbing and assembly task that should always be done with the filtration system stopped and
the line depressurised.
- Stop the filtration pump, close isolation valves and release pressure in the pipework.
- Disconnect the power cable from the electrode and remove the tightening ring.
- Take out the electrode and O-rings, keeping note of their positions if they will be reused.
- Loosen the cell unions and remove the old transparent body from the plumbing.
- Install the new R0740200 body between the unions, ensuring the seals and gaskets are correctly seated.
- Refit or renew the O-rings, insert the electrode and screw on the tightening ring by hand until snug.
- Reconnect the power cable, reopen the valves, restart the pump and check carefully for leaks.
Once fitted, the new Zodiac empty cell body R0740200 restores the original hydraulic performance and visibility of the cell, supporting
reliable salt chlorination and easier routine inspections.
