Jacuzzi 470 (400 series) reference
planetary:
Hi folks,
Now that I've got my 470 installed, I thought I'd try to give back a little (a very little, at first) to our little community.
To aid anyone in the future with research, I've collected a few odds and ends related to the Jacuzzi J-470 into a Google doc. (In internet terms, one might call this a "crowdsourced" reference, or something.) Almost all of this stuff is applicable to the 480, and a fair bit is applicable to the 495 and other tubs in the 400 series.
BTW, for those looking for the 50 amp to 60 amp procedure, it's described in here.
I'll be adding to it over time, as I learn more. Hope it's useful!
Cheers,
Jason

A jacuzzi Hot tub comes set up with a 50 Amp circuit. The move to the 60 amp service IMO was not needed. The 60 amp service allows the heater to remain on while both blowers are running and setting above set point.
The 50 Amp service only allows one blower to run and the heater to stay on.
I had mine wired for the factory recommended 50 amp service. I have had ZERO issues with temp. control and it states in the manual that a 50 amp service is adequate unless the jumper is moved to the 60 amp service.
I have never had heating issues. I actually run my Hot Tub up to temperature and lower the setpoint when we get in. The blowers will induce heat into system.

Thanks, smackman. I've updated the Q&A section a bit. There's a thread of at least one owner who reports 3-5 degrees F loss during a 30 minute soak (though the conditions for that user were unclear). Is that acceptable? I don't know. That's subjective. :)
Given the pretty small cost differential between 50a and 60a service, I think most new tub owners would opt for 60, and just not have to worry about temperate issues -- if their homes can support the electrical load.
Also, 50a isn't, to my knowledge, "recommended" over the other options by Jacuzzi -- it's just the factory default. In the 2012 pre-delivery guide, page 14, Jacuzzi highlights that is a choice, and gives you 3 options to choose from.

I've also updated the Q&A section on filtration (referencing a thread that smackman created earlier this year). It's far from comprehensive, but it's a start...

when I've soaked in the tub when it was 15F or below I've seen that kind of temp drop. So far in 10 years I've only soaked before 0F once.
