•Carry on the measurements of pressure, electric current, and temperature fifteen minutes after an operation is started.
12.2. Breakdown Self Diagnosis Function
Once abnormality detected during operation, the unit will immediately stop its operation (Timer LED is blinking) and maximum of three error codes (abnormality) will be saved in memory. The abnormality of the operation can be identified through the below breakdown diagnosis method:
•Press “CHECK” button at remote control continuously for more than five seconds to turn on the diagnosis mode, “H11” will be displayed at remote control.
•By pressing the TMER “ 
” button once, next error code will be displayed; press “V” button once, previous error code will be displayed.
•If error code displayed matches the error code saved in unit memory (abnormality detected), four “beep” sounds will be heard and Power LED will light on. Otherwise, one “beep” sound is heard.
If “CHECK” button is press again during Cooling operation using test run operation mode for 30 seconds, the diagnosis mode will turn off.
