Analysis or handling of some of the malfunction display:

1. Compressor discharge protection (E4):

Possible reasons: shortage of refrigerant; blockage of air filter; poor ventilation or air flow short passfor condenser; the system has noncondensing gas (such as air, water etc.); blockage of capillary assy(including filter); leakage inside four-way valve causes incorrect operation; malfunction ofcompressor; malfunction of protection relay; malfunction of discharge sensor; outdoor temperature toohigh.

Handling method: refer to the malfunction analysis in the above section.

2. Low voltage overcurrent protection (E5):

Possible reason: Sudden drop of supply voltage.

3. Communication malfunction (E6):

Handling method: Check if communication signal cable is connected reliably

4 Sensor open or short circuit (F1, F2, F3, F4, F5):

Handling method: Check whether sensor is normal, connected with the corresponding position on thecontroller and if damage of lead wire is found

5. Compressor overload protection (H3):

Possible reasons: insufficient or too much refrigerant; blockage of capillary and increase of suction temp.;improper running of compressor, burning in or stuck of bearing, damage of discharge valve;

malfunction of protector.Handling method: adjust refrigerant amount; replace the capillary; replace the compressor; useuniversal meter to check if the contactor of compressor is fine when it is not overheated, if not replacethe protector.

6. System malfunction (H4):

i.e. overload protection. When tube temperature (Check the temperature of outdoor heat exchangerwhen cooling and check the temperature of indoor heat exchanger when heating) is too high,

protection will be activated.

Possible reasons: Outdoor temperature is too high when cooling; insufficient outdoor air circulation;refrigerant flow malfunction.

please refer to the malfunction analysis in the previous section for handling method .
