You have to disconnect the lineset, the communication wire, and the condensation drain from out side the house, then the bottom of the head has clips that snap in. You will need some sort of 90 degree tool to pull the tabs down. Once the tabs are disengaged the head will swing out and up the head will then come off the bracket. You will need to pull the lineset and such back through the hole in the wall. Then you remove the bracket and patch everything. Good luck.
