7. FINISHING
After checking for gas leaks (refer to the installation manual of the outdoor unit), perform
this section.
Install thermal 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 thermal
insulation and indoor unit pipe thermal 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
thermal insulation and indoor unit pipe thermal insulation together and bind them with
vinyl tape so that there is no gap.
((A) Rear, (B) Right and (C) Bottom piping)
Connection pipe
(thermal insulation)
Bind the pipes together so
that there is no gap.
Seal A is used when the diameter
of gas pipe is Ø12.70 or more.
(For (D) Left bottom piping, (E) Left piping, (F) Left rear piping)
• Wrap the area which accommodates the
rear piping housing section with cloth tape.
• Bind the connection cable with
Connection cable (Power supply cable)
vinyl tape.
• Bundle the piping and drain hose
together by wrapping them with
cloth tape over the range within
which they fit into the rear piping
housing section.
Connection cable
(Transmission and remote controller cable)
(2) Temporarily fasten the connection
cable along the connection pipe with
vinyl tape.
(3) Fasten the connection pipe to the
outside wall with a saddle, etc.
(4) Fill the gap between the outside wall
pipe hole and the pipe with sealer
so that rain water and wind cannot
blow in.
(5) Fasten the drain
hose to the outside
wall, etc.
