2. How to check
* Hydro Unit : Before and after the Compressor operation, EVA Out tem-
perature difference is less than 3
°C.
Restart operation after connecting
the connector to the PCB.
After separating the Indoor EVA In sensor
connector from the PCB, measure the
resistance value between the two terminals.
Yes
No
