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.

CAUTION
• The filled-out label must be adhered in the proximity of the
product charging port.

• If you cannot add the whole quantity of the refrigerant while
the outdoor unit is stopped, open the gas side and liquid side
service valve. Then, add remaining refrigerant by pressing the
refrigerant adding button of the outdoor PCB.
• If you use the refrigerant charging function from the PCB,
outdoor unit will operate and charge the refrigerant. At
this time, you must use gas side manifold gauge for cooling
operation and use charging port for heating at the manifold
gauge for heating operation.
