Indication of the present operation state

-

 normal

-

 abnormal

-

 under preparation or under test operation

11.4. Test operation

Check the stop valves
Make sure to open the gas and liquid line stop valves.

After installation, perform the test operation.
Unless the test operation is performed, the error code "

U3

" is

shown on the remote controller and the unit cannot be operated.

Performing the test operation

1

To  protect the compressor, make sure to turn on the power
supply 6 hours before starting operation.

"Setting mode 1"

on page 15

).

3

Press the 

 button for 5 seconds when the unit is at

standstill. The test operation starts when the H2P led blinks and
the remote controller indicates 

 (test operation) and 

(external control).

It may take 10 minutes to bring the state of refrigerant uniform
before the compressor starts, but that is not a malfunction.
The test operation is automatically carried out in cooling mode
during 15~30 minutes.
Depending on the situation, the refrigerant running sound or the
sound of a magnetic solenoid valve may rise during this
operation.
The following items are automatically checked:
-

Check for miswiring

-

Check if stop valves are open

-

Check of refrigerant charge

-

Automatic judgement of piping length

4

After the test operation (maximum 30 minutes), the unit
automatically stops.Check the operation results by the outdoor
unit led indication.

5

Measure to be taken when operation finishes abnormally

1.

Confirm the error code on the remote controller.

After the abnormality is corrected, press the 
button and reset the error code.

4.

Start the unit again to confirm that the problem is properly
solved.

5.

If no error code is indicated on the remote controller, it is
possible to start operation after 5 minutes.

Possible functions

A

additional refrigerant charging operation.

B

refrigerant recovery operation/vacuuming operation.
