DIAGNOSTIC DISPLAYDiagnostic Method(Way to retrieve abnormality
memory)
During stop operation, when check button at remote control is
pressed for more than 5 seconds, diagnostic display code will be
shown. When timer and button is pressed, diagnostic display code
will be shown in sequence. When abnormality content is as same as
diagnostic display code, receiving sound of pep pep pep. Is
occurred for 4 seconds and POWER LED will it for 30 seconds.
(Way to delete abnormality memory)By starting cooling operation
using test run operation mode, and pressing check button at remote
control, the previously recorded abnormalities are deleted.
