Recharging my R290 mini split air conditioner and heat pump

Documenting my attempt at repairing an R290 refrigerant based mini split air conditioner and heat pump unit ElectriQ EIQ-12WMNIV-V4. As R290 gas is just an ultra pure form of propane, it doesn't fall into F gas regulation and doesn't require a special license to purchase or own in the United Kingdom. This video is for educational and entertainment purposes and is by no means a guide on how to regas an R290 refrigeration unit. I am surely doing it wrong so don't copy me.
