6. FINISHING

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.

6.1. Connection pipe, cable and drain hose

(1) Insulate between pipes.
• Overlap the connection pipe heat insulation and indoor unit pipe heat insulation.
• Wrapping the connection pipe with cloth tape over the range within which they fit into the
rear piping housing section.
• Fasten the pipe bracket with the screw.
(2) Fill the gap between the outside wall pipe hole and the pipe with sealer so that rain
water and wind cannot blow in.
(3) Fasten the drain hose to the outside wall, etc.
