I Preparing the indoor unit's piping and drain hose for

To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.

the remaining parts must be
removed clearly so as not to
damage the piping and drain
hose, especially power cord
and connecting cable.
