You can also prepare the necessary tools for installation first: electric drill, cross screw pen and a square plastic template. Fix the square plastic template on the wall first, and the height can be easily adjusted according to your home space. When fixing, fix it with screws produced by the original factory, and then drill two holes with an electric drill. If it is an instant kitchen treasure, the power is generally below 4000W, and it can be installed under or above the kitchen sink, with good water pipes and lines and splash-proof sockets.
