    Sir,
    First of All Eid Mubarak from me and my Muslims community...
    Besides, the above modification is too informative and readable.
    Actually, the above system have modification capability and availability of transformer tappings on primary windings. However, if it would not available what will be the solutions its very important.so therefore, because off above topic i want to share solution.

    some time Transformer having only 110 voltage rating and winding. what will be the solution if that condition found..
    Simple solutions are mentioned below:

    1... Make Transformer winding for 220 volts but its not reliable because winder will change the wire guage SWG from recommended guage to lower guage for space require of excess winding i.e. 220volts. therefore, transformer will be faulty every after some moments when heat and over use.

    2.... Make arrangements of 110 volts small transformer and Installed inside unit with series of input primary winding as fuse coil. not need to be used small transformer secondary because small transformer only provide resistance and fusing between transformer and 220 voltages.

    thanks you
