I have a line on a Catalina cl-750 hot tub. I can't find very much about it. Wondering if anyone had any information like when it was made, manual etc. It seems to have a radio and fibre optic lights and looks like the cl-750 on this German page. http://www.catalinaspas.de/cl_serie/index.shtml I think it was made in eastern Canada. Also how well would it do in Edmonton, Alberta winters? Possible -40C. Thanks

I have a 2003 Catalina spa. After a power outage, the spa keeps giving the OHH error code. When I flip the breaker, wait a few minutes, then flip on, the spa goes into prime mode, but within a few minutes throws the OHH code again and shuts down. The water is cool, so I know it's not truly overheating. I have replaced the M7 sensors as that was the first issue after power was restored. I found that one of the sensors had gone out. I've checked the flow and it is good. Another article I read here mentions a diode being bad on the circuit board. How do I locate and repair this diode? Thanks in advance for any help!!

My friend picked up a Catalina Spa yesterday for free and wants to set it up in my backyard. Where do I locate a model number for this? We'd like to get it up and running and see where we stand with this. The previous owner said that it had a leak in one of the hoses. I'd like to research this and get as much information as possible but I am unsure where to start or how to even locate the model number. Any information or advice would be greatly appreciated. Thanks.

Hi, hoping for some help with a "FL" flow switch error. Are fairly new owners of used 10 year old Catalina Bel Air Limited Edition spa. It has the Balboa CAT 100 spa pack and 3-button topside controls, single pump system, ozone, but no circulation pump. Had been working perfectly until we changed the filters yesterday, which were pretty dirty after 2 1/2 months and came with the spa so I don't know how old they were. We did clean the used filters 3 months ago when we installed the spa, but again, I don't know how old they were. The system uses (2) screw-in cartridge filters, which I purchased from Spa Depot online. After replacing the filters while the spa was full as normal, I circulated the water with the pump on high to clean out the debris that fell into the water after removing the old filters. Worked fine until I turned the pump down to low and noticed shortly afterward that there was no water flow and the topside panel said "FL", solid on, not flashing. I turned off the breaker, turned it back on and it worked fine, until later after the pump came out of high speed, should have been on low to heat and circulate. We were able to use the spa, but same thing after turning it on low, it wouldn't come back on without cycling the breaker. Water temperature was good at 100 degrees, jets work normally, and water flow into the filter seemed a little better since changing the filter. We did notice that there is less suction on the lower suction fitting, which we assumed was due to better water flow through the new, clean filters. This morning, the spa was 94 degrees, and the solid FL code was back, even though the pump was only on low speed overnight during the 4 hour circulation and heating cycles. Could this be due to better water flow through the filters and perhaps the computer is detecting this new condition, causing the error code? Can the flow sensor be adjusted? Could there be air in the system after changing the filter, even though I changed it while the spa was full? Could there be debris in one of the pipes near the sensor, and if so, can it be flushed out other than normal operation? Should I put the old filters back in? Does this have anything to do with changing the filters? Any help would be appreciated. BTW, my husband is an Electrician and can troubleshoot any wiring issues, though he has not worked on spas before. Just trying to help him out since he's a busy guy right now, and we have some cold weather in the forecast, so looking to avoid freezing problems. Thanks!

Can someone help? I have a catalina xl11000 spa. Installed new balboa spa pack. The pack does not support fiber optic lights. Is ther any way i can make the fiber optics work. Maybe wire it direct with some sort of separate switch to control the lights?
