Question: What shuold we do, if the unit display error code? Such as "E1", or "F8"

Answer:

These error codes only can be solved by after-sale service engineers, please call our hotline for help.

ERROR CODE	FAULT DESCRIPTION	ERROR CODE	FAULT DESCRIPTION	ERROR CODE	FAULT DESCRIPTION
E7	Communication fault between indoor and outdoor units	F6	outdoor ambient sensor failure	F21	Outdoor coil temperature sensor
E1	Indoor temperature sensor failure	F7	Suction temperature sensor failure	F22	Outdoor Alternating current over current protection
E2	pipe temperature sensor failure	F8	DC fan motor malfunction	F23	Compressor U-phase overcurrent Compressor V-phase overcurrent Compressor W-phase overcurrent
E4	Indoor EEPROM failure	F9	Module reset	F24	CT detection current abnormal protection
E5	Indoor anti-frosting protection	F11	Loss of synchronism detection	F25	Abnormal of compressor discharge sensor
E9	Indoor unit overload in heating mode	F12	EEPROM failure	F27	Compressor current sampling circuit fault
E14	Indoor fan motor malfunction	F13	Lack of refrigerant	F28	Compressor position detection circuit fault
