8. FINISHING
(1) Insulate between pipes.
• Insulate suction and discharge pipes separately.
• For rear, right, and bottom piping, overlap the connection pipe heat insulation and
indoor unit pipe heat insulation and bind them with vinyl tape so that there is no
gap.
• For left and left rear piping, butt the connection pipe heat insulation and indoor unit
pipe heat insulation together and bind them with and vinyl tape so that there is no
gap.
• For left and left rear piping, wrap the area which accommodates the rear piping
housing section with cloth tape.
• For left and left rear piping, bind the connection cable to the top of the pipe with
vinyl tape.
• For left and left rear piping, bundle the piping and drain hose together by wrapping
them with cloth tape over the range within which they
fi
t into the rear piping
housing section.
(2) Temporarily fasten the connection cable along the connection pipe with vinyl tape.
(Wrap to about 1/3 the width of the tape from the bottom of the pipe so that water
does not enter.)
(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.
