Each Mitsubishi mini-split defines the right line set size, which includes pipe size, maximum and minimum length, and the maximum height difference between the outside and interior units. You could be tempted to utilize an outdated line set that isn’t compatible with your system, but this will fail. The air conditioner board is unlikely to be damaged by stray electrical energy if the unit is grounded.
One of the problems that might arise when a Mitsubishi mini-split air conditioner is not grounded properly is compressor or board failure. While exiting the indoor unit, your unit should have a drain line that is pitched at least 5 degrees down. To avoid any problems caused by grounding issues, consult with an electrician. If your electricity changes often, a surge protector should be installed.
