If all you are changing is the connection for the power, maybe you better check that the power rating is correct.
Running a 220/240 volt piece of equipment on 110 volts does not always work well, nor does a 110 volt on 220/240 volts
Some burn out.
Some cause fires.
Some have even caused electrocution.
Electricity is not to be played with if you do not know what you are doing.
