Hot Tubs Spas

Does anyone have a cal spas fiesta Hot Tub that is wired 220v?
I have a 2001 cal spas fiesta Hot Tub with a G.E. Whisper control panel. It was wired 110v up until I moved a few weeks ago, now I have wiring in place to connect it to 220v although I do not have a wiring diagram to view the wiring placement. If anyone has a cal spas could you please help, maybe post a picture of the inside of your control panel. Thank you all for your time, Struggling not bubbling…
You need a step down transformer 220/110 V
connect the control panel to 110 V , and the 220 V to main source
transformer power ( KW ) or (KVA) should match SPAS Hot Tub power + 15 % ( as facor of safety )
