I purchased a used Tempstar HH that is rated @460VAC 3phase, I have only 208VAC,3 phase available. Can I convert this unit to run on 208VAC? Steve
Hello. If the unit is rated 460v, 3phase, the only way you can get it to meet your supply of 208v, 3phase, is:
a) have a transformer installed to make 460 from your supply by an electrician, or call your power company and see if 460 could be supplied to your building, but it would only be for that machine.
or
b) replace the heating elements for the 208v supply, have the pump motor checked to see if it will work on 208v, and a control transformer for the control circuit, as well as all the wiring related to the pump and heaters, as on 208v, they will draw more current than on 460.
so, can it be done? yes. Is the expense worth it? only you can answer that, However I would suggest that you resell that machine, and get the correct one from the start.
Hope that helps, and thank you.
Keep in mind, that even though you are able to make changes to the machine to make it work with voltage ather than what it is designed to work with, any of those changes to the machine will make it inconsistent with the UL and NSF designation on the plates installed on the machine by the manufacturer. This means that the machine will be in non-compliance with UL and NSF regulations, putting you at risk for electrical problems/fires caused by the machine, health code non compliance, and regulatory fines.
There are only 2 solutions here.
A) Have an electrician install a 460 3 phase circuit for the machine that you have, or
B) Get a machine that is designed to work with your building's current voltage.
Any choice other than those is not adviseable.
I'm 3 years late, but it may save anyone looking at this from a lot of headache/fines from making a bad choice.

No its not able to be converted that way you wouldn need to change your current to match that of the dishwasher
If you have 3phase motor then cant convert on 208VAC,but if motor is 1phase you can convert must have 220-250VAC.
