ok, my father-in-law gave me an old hot tub that was out at their cabin... hasn't been used in a while and he thinks the thermostat is broken as he said the last time he used it it would get hot and then cool off... I'm not too particularly concerned with this issue yet and I still need help on hooking it up, etc...

So... at my house, the previous owners had a 220v hot tub so there's a 50amp double breaker in the breaker box and a thick cable running though the attic over to the side of the house where the hot tub sat... it is cut off at the end though. I think I can run the cable a bit better and get it through the hole and out to the tub (or very close).

The hot tub is 110v. It has a normal 3-prong plug on the cord. The model # is Z110/310 H490000 with R574 electronics. It was purchased in 2000 or so. It has Jacuzzi branding.

My first question: does anyone know if this tub is relatively easy to convert to 220v? I've read that some are and some aren't...if so, any details on how to do this or do I have an electrician do it?

My next question: is it possible if I have an electrician remove the double-breaker in the box and set it up with one breaker, for the same cable that's currently setup for the 220v to be used for a 110v setup? I'm trying to minimize cost here and would rather NOT have to pay an electrician to run cable through my attic if not completely necesary. I could take care of getting the cable out to the tub if it'd save time.

I have a 110v outlet on the deck near the tub but I don't think it's a dedicated line so I'm thinking I can't run the tub off of it. Is that correct?

I'm interested in any advice or research topics you can point me to... trying to minimize cost to try and setup a free hot tub. Hoping that I can do everything for a couple hundred bucks or less...

Thanks!

From the owners manual;

This conversion will increase the heating capability
of your spa's heater and convert the output from 1kW
to 4kW. We recommend that this rewiring be done by a
qualified electrician. A wiring diagram is provided on
the inside cover of the electrical control box. When this
conversion to 230 VAC has been made, any combination
of operating modes is possible, including having
the heater on when the whirlpool mode is activated.
Also, the heat-up rate will greater.

To convert to 230 VAC, 50 AMP operation:

1. Turn OFF 15 AMP breaker at main electrical panel.
2. Open the skirt door access panel.
3. Loosen and remove screws securing the electrical
cabinet cover and set them aside.
4. Loosen screws at bottom side of terminal block and
remove power cord cable clamp. Remove and
discard GFCI power cord.
5. Install 230 VAC 4-wire power cord in accordance
with local code requirements. Follow directions
according to the wiring diagram on back side of
electrical cabinet cover.
6. Replace electrical cabinet cover and tighten screws.
7. Make sure spa is filled with water to proper level.
Turn ON 50 AMP GFCI breaker at the main electrical
panel.
8. Test GFCI for proper operation.

WOW... sounds really easy... definitely better than converting the existing 220 cable to 110 at the box!

Any idea if there is somewhere online I can get the manual? I have A manual but it's just to some other Jacuzzi spa... definitely not the one I have. I would love to have the owners manual while I'm setting this thing up!

Thanks!
