Identify a replacement by its reference

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

Distinguishing the model and its variants

Suffixes in a reference may indicate a different configuration or accessories. In particular, check which pressure switch, fittings, and seals are required 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 connect it. Installation must follow the system instructions. Follow the manufacturer's recommendations for circulation, filtration, and water balance.
