Upon arrival, I checked main power supply at the disconnect. I discovered that there was not any power being supplied. Customer stated it was performing great, but it was turned off for the solar guys to work. The unit has not operated since then. I traced power back to the main breaker box. I located an unlabeled 50amp breaker in the off position. I turned it on and the mini split regained power. I tested the mini split in heating mode and yielded a fantastic temperature split. Customer had to leave to go back to work. I collected my dispatch and got signatures.
