Cut out a slit hole on the dressing board (right) and set the piping. (Refer to Fig. 16)
•
When piping is complete, cut the removed penetration lid into the shape of the piping using
scissors and attach. As when before removing the top penetration lid, secure the lead lines
for the swing motor and thermistor by passing them through the clamp section on the top
penetration lid. (Refer to Fig. 14.17)

When doing this, block any gaps between the piping penetration lid and the pipes using putty
to prevent dust from entering the indoor unit.
