Replacement to be identified by reference

The C2400-0535 format is associated with first-generation Balboa-style heaters. Compare the complete reference, connections, mounting hardware, and plumbing with your installation; the Cal Spas brand alone does not confirm compatibility.

Distinguishing the model and its variants

Reference suffixes may indicate different configurations or accessories. In particular, check the pressure switch, end fittings, and required gaskets rather than assuming they are included based on a photo.

Installation and maintenance

Have a qualified spa technician diagnose the issue, select the part, and make the connections. Installation must comply with the system instructions. Follow the manufacturer's recommendations for circulation, filtration, and water balance.
