8-2-68. The low pressure detection error at the initial of compressor start
■
Check method

1. Measure he pressure at the state of system stopping with manifold gauge.
■
2. Check the value of low pressure sensor with view mode or S-net.
■
3. If the value of 1 and 2 are similar, most of refrigerant must be leaked. Discharge the rest refrigerant,
and vacuum and charge again.
■
4. If the difference between value 1 and 2 is large, it must be a connection defect of connecter or sensor
