Step 15. Auto check(Installation
commissioning mode)
• This is a self-diagnosis function to determine the
installation status and product integrity in the initial
installation.
(This model requires the Auto check to be
implemented in the installation step before its normal
operation is initiated.)
• Procedures of Auto check
1 Check the product installation status.
– Check the power supply, communication cables,
service valve openings, and quantity of additional
refrigerant.
– In the initial power supply after installation, the
warning of non-fulfilment of Auto check (
) will
be indicated on the outdoor unit and the system
will not function properly.
2 Enter the mode of Auto check.
– Press the K1 button 7 times consecutively.
– During the Auto check, the display will show “
“ “
“ BLANK” “BLANK” and it will take about 10 to 30
minutes for completion.
3 The mode of Auto check will then be completed.
– Successful Auto check: After checking the blinking

(
), press the K1 or K2 button to turn the
status to the standby mode for normal operation.
– Failure of Auto check: An error code blinks on
the display. Resolve the error by referring to the
details on the Troubleshooting page about how to
troubleshoot for each error code, and then perform
the Auto check again.
NOTE
• If you intend to install more refrigerant piping prior
to entering the mode of Auto check, make sure
that the refrigerant to be added meets the related
requirements.
In this process, it is possible to test the cooling test
mode (K2 switch: once) and heating test mode (K1
switch: once).

system status by pressing the K4 switch.
• In the case that there is an error during the Auto check,
the Auto check will stop. In this case, take a measure for
the error and then try the test operation again.
• If the test operation is not completed properly, the
