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.

Precautions for remote controller installation

button, and check that the air conditioner operates
correctly.
When using the remote controller to detect
the room temperature, observe the following
precautions during installation:
• Avoid locations where the remote controller will
be exposed to the direct path of air blown from
the air conditioner.
• Avoid locations where the remote controller will
be exposed to direct sunlight.
• Avoid locations where the remote controller will
be exposed to direct heat sources.

Caution for Pump Down

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
Pay a special attention to the rotating of the fan
while operating.
