7. FINISHING
CAUTION
After checking for gas leaks (refer to the Installation Manual of the outdoor unit), perform
this section.
Install heat insulation around both the large (gas) and small (liquid) pipes. Failure to do
so may cause water leaks.
7.1. Connection pipe, cable and drain hose
Insulate the drain hose, if necessary, to prevent it from freezing.
(1) Insulate between pipes.
• For (A) Rear, (B) Right and (C) Bottom piping, overlap the connection pipe heat insula-
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.
((A) Rear, (B) Right and (C) Bottom piping)
Indoor unit pipe

of gas pipe is Ø12.70 or more.
Butt connection pipe (heat insulation) against
the indoor unit pipe (heat insulation) and wrap
with seal A so that there is no gap.
(For (D) Left bottom piping, (E) Left piping, (F) Left rear piping)
