Troubleshooting ]
(7) In case of SV5b (2-way switching valve) (only for P126-P234 models)
This 2-way valve is closed when powered. Check the LED display and the switching sound to check whether the valve
has no faults.When cooling, the switching coincides with 21S4b. When it is difficult to check by the sound, check the tem-
perature at the front and the back of the pipe to check whether the refrigerant is flowing.
∗
Do not give an impact from the outside, as the outer hull will be deformed, leading to the malfunction of the inner valve.
