Hello Everyone,

I just inherited a Liesure Bay 4 person hot tub. Originally, it was set up for 220v. But, because I don't have 220v available I had to switch to 110v. I want to be sure I did everything needed to do the conversion. I may have missed something that is causing the no heat issue.

I omitted one of the two heavy black wires (marked line 2 in the ProShield). I also went ahead and disconnected it from the panel inside the ProShield. Then I toggled the switch from 220 to 110 inside the housing.

I had read in another posting that there is one cable that supplies the heater with juice. Is this lead fed from Line 2 and the cause of my issue?

Any help is greatly appreciated.

Thanks,

Pep

That should pretty much do it....

A couple of questions....

Have you given it ample time to heat up? (It will gain ~2F/ per hour)
Do you have a spa cover?
Does it have a switch for "Auto/timer?
If the spa has a 24 hour circ pump, it should begin heating right away, but if it incorporates a 2 speed jet pump to handle filtering, heating, and thraputic duties, you should know that it will only heat on "low speed"

Be sure that you're not running it on high speed, and leave the air blower off.

Also, you probably have a "heat indicator" light located on the control box (*note: NOT the heat indicator on the topside control) Is the heat indicator lit on the control box?

Hmm.. might want to be sure that you completed the heater circuit. When you removed the "red" wire, is there a jumper wire that you replaced somwhere?

The heater used to have two wires supplying power (the black was 110v, and the red was 110v on a differetn phase, thus completeing the 220v circuit)
Now that the red is removed, a single hot wire going to 1 pole of the heater won't do anything...you must complete the circuit. Possibly running a neutral "jumper" from the main neutral to the spot where the red wire used to be will solve this issue, if this is the case. Be sure you use a heavy guage jumper wire (12 guage should do fine w/ 110v)

Be sure you do this on the LOAD side of the GFCI, if the GFCI is located in the spa control box, otherwise you will trip the GFCI if you just run it from the main terminal block.
