220 plug with 20amps-outlet has 220 volts with 30 amps,will this work

Just Change Breaker to 2 pole 20 amps.
What type of plug on end of cord, Or is it hardwired?
Does it say, it draws 20 amps, if so, will need to stay 30 Amps.
80% of 20 amps is 16 usable. Does it have a Wattage rating.
Check nameplate.
Receptacle needs to match plug. Will also help determine breaker.

Manufacture rules, "rule"

The plug is three prong,and says 250 volts and 20 amps on the end you plug into the wall.The tanning bed weighs more than a large freezer,and has been a thorn in my side since I purchased it.I basically want to make sure it works properly,so I can sell it to someone.It was purchased less than 2 years ago from a distributer,that no longer sells this brand.I bought a storage unit at auction,and this bed was inside the unit.The outlet I am planning on using was once used for a dryer.
