unit combination Nos.
After automatic address setting has been completed, be sure to
record them for future reference.
List the outdoor unit system address and the addresses of the
indoor units in that system in an easily visible location (next

means that cannot be erased easily.
Example: (Outdoor) 1 – (Indoor) 1-1, 1-2, 1-3…
(Outdoor) 2 – (Indoor) 2-1, 2-2, 2-3…
These numbers are necessary for later maintenance. Please be

Remote Controller Test Run Settings
1
Press the remote controller
button for 4 seconds or
longer. Then press the
button.
●
“TEST” appears on the LCD display while the test run is
in progress.
●
The temperature cannot be adjusted when in Test Run
mode.
(This mode places a heavy load on the machines.
Therefore use it only when performing the test run.)
2
The test run can be performed using the HEAT, COOL, or
FAN operation modes.
Note:
The outdoor units will not operate for approximately
3 minutes after the power is turned ON and after
operation is stopped.
3
If correct operation is not possible, a code is displayed on
the remote controller display.
(Refer to “7-6. Meaning of Alarm Messages” and correct
the problem.)
4
After the test run is completed, press the
button
again. Check that “TEST” disappears from the remote
controller display.
(To prevent continuous test runs, this remote controller
includes a timer function that cancels the test run after 60
minutes.)
*
If the test run is performed using the wired remote
controller, operation is possible even if the cassette-type
ceiling panel has not been installed. (“P09” display does
not occur.)
7-5. 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 pump down. In this case,
use another refrigerant collecting system.
