Use the remote controller to check the addresses of the indoor
units. Press and hold the
seconds or longer (simple settings mode, "ALL" appears on the
remote controller). Then press the
indoor address.
(For the system addresses of the No. 1 outdoor unit, each time
the button is pressed, the address changes as follows: 1-1, 1-2,
...)
The indoor unit fan operates only at the selected indoor unit.
Confirm the indoor unit address. (For the system addresses of
the No. 2 outdoor unit, the displayed addresses are 2-1, 2-2, ...)

controller mode.
10-32-4. Indicating (marking) the indoor and outdoor unit
combination number
Indicate (mark) the number after automatic address setting is
completed.
(1) So that the combination of each indoor unit can be easily
checked when multiple units are installed, ensure that
the indoor and outdoor unit numbers correspond to the
system address number on the outdoor unit control PCB,
and use a magic marker or similar means which cannot
be easily removed to indicate the numbers in an easily
visible location on the indoor units (near the indoor unit
nameplates).
Example: (Outdoor) 1 – (Indoor) 1, 2...
(Outdoor) 2 – (Indoor) 1, 2...
(2) These numbers will be needed for maintenance. Be sure to
indicate them.

to the direct path of air blown from the air conditioner.
• Avoid locations where the remote controller will be exposed
to direct sunlight.

Pump down means refrigerant gas in the system is returned
to the outdoor unit. Pump down is used when the unit is to be
moved, or before servicing the refrigerant circuit.
CAUTION
● This outdoor unit cannot collect more than the rated
refrigerant amount as shown by the nameplate on the
back.
● If the amount of refrigerant is more than that
recommended, do not conduct a pump down. In this
case use another refrigerant collecting system.
