Cocoon Cooltech - 3.2. Equipment Faults

Electrovalves circuit identification
Block this tube
To the pump input are connected 2 tubes, one goes to EV1 and 2 and the other one to EV3 and 4.
Make the test, bending the tube that goes towards EV 3 and 4 as shown in the image.
If after blocking the tube the vacuum loss persists, proceed replacing the CPU, since possibly the
vacuum sensor is faulty.
