6 E4 High-Pressure
protection
1.Check if any object stacking at inlet
2.Check if dust filters gets dirty, if yes, clean the filter;
3.Check if it’s fan motor or fan capacitor defect, if yes, replace the part
4.Check if high pressure is around 2.8~3.2Mpa when at dry bulb 30C,
wet bulb 26C. If it’s higher than that, please check if any stuck in
refrigerant system. If pressure normal, please check if any defect on
high pressure switch

protection
1.Check if low pressure normal. If low pressure is around 1.0~1.2Mpa at
dry bulb30C, wet bulb26C. That’s normal. if not, please check if any leak.
Repair the leak and recharge gas.
2.If it’s normal, please check if any defect on low pressure switch

1.Check if any object stacking at inlet
2.Check if filters gets dirty
3.Check if it’s fan motor or fan capacitor defect, if yes, replace the part
9 EE Communication
failure
1.Check if connection between PCB and LCD gets loosen.
2.Check if defect on signal wire, if yes please replace it.
3.Replace PCB or LCD
10 EC Over heat
protection
(for product with
additional heater )
1.Check if any object sucking at inlet
2.Check if filters gets dirty
3.Check if it’s fan motor or fan capacitor defect, if yes, replace the part
4.Check if electrical heater over heat protection button tripped.
if yes, press the button.
