Any generic pressure switch of the same size will work.
Any aftermarket ozonator will work.
The filter cartridge can be determined by the exact size of what you have It's either a 50 [10-7/8" tall] or 75 [14-3/4" tall] square foot cartridge).

Thanks Dr. Spa. Is this determined by this part of the serial number?
S069781184TAA
Can you tell what model it is?
The owners manual date 6/96 says "Paradise Series".
In the manual under the Filter Cartridge Size section, it says the Hawaiian, Tahitian, and Riviera spa models have a 75 sq ft filter cartridge, whereas the Aruba, Martinique models have a 50 sq ft filter cartridge. I have the larger 75 sq ft filter cartridge, so I believe I have the Hawaiian, Tahitian, or Riviera model.
The current configuration of the Tahitian model looks basically the same as what I have (6 person, 84"x84", lounger seat on control panel side, filter in corner to the right of control panel) so I suspect that I have a Caldera Spas 1997 Tahitian Paradise model. Based on the serial number, is this correct or do I have something else?

Please help😜 I purchased a Caldera Tahitian spa today. The previous owner said that this was the serial number C45W2J3083 can someone please tell me what this means. I would like to buy maintenance parts and chemicals but I do not know if the info the guy gave me is correct??? 2007 Caldera Tahitian is all I know...
Thank you so much!
Soaking in WV:
I've just purchased a gently used Caldera Martinique spa; arriving today. I'm trying to figure out what year this is so I can get the right manual and begin to get to know this spa. The model number is MRA1C1071. If I'm reading this thread correctly, that would mean this is a spa produced in the first quarter of 2001? (1C) The serial number, on the other hand, is 51286-12200101170052 -- which seems a much longer serial number than the others I'm seeing in this post for Caldera tubs. So that has me confused. It also says the following on the serial number tag: "System 9800CP Caldera Millen 38984"
Can Vanguard or Dr. Spa or someone else confirm that I'm interpreting the model number properly before I start ordering parts for this? And does anyone know what all that other info on the S/N tag means?
