Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way. Do you have a schematic for the bed? Apparently, owners can request one HERE Once we have a schematic, we MAY be able to figure out how to wire it for single phase. Let me know.

Thanks for those schematics. I see no way of converting that bed unfortunately. The bed uses 415V and 240V - the two voltages available in a 415V three phase supply.
You would need to provide those two voltages and do some major rewiring. That's way beyond the scope of what I can do here.
Why do you need to convert it? Do you not have the voltage available? Do you have any three phase voltage available?
Please let me know so that we can continue.

I only have single phase power.
I have a guy coming to do what you say can't be done tomorrow.
It's as simple as running a 63amp line to the room then changing some wires and jumpers.
