Cut off the lower part of the gas liquid and equalising stop valve pipes along the black line use an appropriate tool e g a pipe cutter 84
It is very important that all refrigerant piping work is done before the units outdoor or indoor are powered on when the units are powered on the expansion valves will initialise this means that the valves will close 84
Notice 84
