2. Outdoor unit (1) Check Items • After installation of indoor and outdoor units,and piping 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 substrate.
[3] Self-diagnosis Retrieve the error history of each unit using the remote controller. Switch to the self check mode. Set the address or refrigerant address No. you want to self check. When the H [CHECK] button is pressed twice successively When the TEMP.
Remote controller diagnosis If operation cannot be carried out from the remote controller, use this function to diagnose the remote controller. 1 First check the power mark. When normal voltage (DC12V) is not applied to the remote controller, the powermark goes off. When the power mark is off, check the remote controller Power mark wiring and the indoor unit.
