tion and indoor unit pipe heat insulation and bind them with vinyl tape so that there is no
gap.
• For (D) Left bottom piping, (E) Left piping, (F) Left rear piping, butt the connection pipe
heat insulation and indoor unit pipe heat insulation together and bind them with vinyl
tape so that there is no gap.
