2) Unit
1) Check Items
• After installation of the unit, and electric wiring work, check that the unit is free
from leaks of refrigerant, loosened connections, and incorrect polarity.
• Check that there is no negative phase and open phase. (The F1 message for
negative phase and the F2 message for open phase will flash at LED 1 on the
outdoor-side controller board. If this happens, rewire correctly.)
• Measure the impedance between power terminals (Single phase: L, N,
triple phase: L1, L2, L3, N, ) and the ground with a 500 V Megger and check
that it is 1.0 MΩ or more. Do not operate the equipment if measurement is less
than 1.0 MΩ.
• When there is no error at the unit.
(If there is an error at the unit, it can be evaluated at LED 1 [digital display] of
the outdoor-side controller board.)
• The stop valves are open both the liquid and gas sides.
After checking the above, execute the test run in accordance with the following.
2) Test run start and finish
• Operation from the indoor-side controller board
Execute the test run using the installation manual for the indoor-side controller
board.

12.3. Self-check

Retrieve the error history of each unit using the remote controller.
1 Switch to the self check mode.
When the H [CHECK] button is pressed twice successively within three sec-
onds, the display shown below appears.
Self check address or self check refrigerant address
3 Self check result display <Error history> (For the contents of the error code, refer to 13. Troubleshooting, error code list.)
Error code 4 digits or error code 2 digits
4 Error history reset
The error history is displayed in 3 Self check results display.
When the D [
MENU] button is pressed twice successively within three sec-
onds, the self check address or refrigerant address flashes.

• Operation from the outdoor-side controller board
Execute settings for test run start, finish and operation mode (cooling, heating)
using the DIP switch SW 4 on the outdoor-side controller board.

1 Set the operation mode (cooling, heating) using SW 4-2
2 Turn ON SW 4-1, The operation mode for SW 4-2 will be adhered to, and

3 Turn OFF SW 4-1 to finish the test run
• There may be a faint knocking noise emitted from the proximity of the fan
during the test run. This is torque fluctuation occurring due to control of fan
revolutions. There is no problem with the product.
Note:
The SW 4-2 operation mode cannot be changed during the test run. (To change
test run mode, stop the equipment with SW 4-1, change the operation mode,
then restart test run with SW 4-1.)
•
If the 2-hour timer is set, the test run will stop automatically after 2 hours.
•
During the test run, the room temperature display shows the unit indoor-side
liquid piping temperatures.
