Installation Procedure
Insulating the pipe located inside of the
outdoor unit
• With a pipe insulator, insulate the pipe up to whole service
valve located inside of the outdoor unit.
• Seal the gap between the outdoor unit pipe and the insulator.
Rainwater and dewdrops may soak through the gap between
the pipe and the insulation of the outdoor unit installed on the
outside.
• Separate the cover of the pipe and close it after insulation
work. Only remove a knock-out hole cover where the pipe
will be installed. If the knock-out hole is open unnecessarily,
it must be closed. If not, small animals such as squirrels and
rats may get into the unit through the hole and the unit may
be damaged.
