Error EC: Refrigerant leakage detection
Shut off the power supply and turn it on 5 sec-
onds later. Is it still displaying the error code?
Is there cool air blowing out from indoor air
outlet?
Check if T2 sensor is well fixed. Correct the
installation or replace T2 sensor. Does the
problem remain again?
Is there any leakage? Especially the connec-
tions parts, such as the gas valve and the liquid
valve.
Replace indoor PCB.
Repair the leakage and recharge the refrig-
erant.
Is there any blocking? (such as the capillary or
the welded points of the pipes).
Clear the blocking.
