One of our sites has various Mitsi Elec split systems on. Mainly the older 407c systems.
We have had a fault come up recently that keep causing the system to go into fault. We are suffering with a U1 fault. I am sure this can be caused by a high pressure switch issue. Possibly being open circuit?
When guages are attached, the standing suction pressue is very high however we are unable to get running pressures due to the system going into fault instantly on start up.
Any help, advice and things to check would be much help

We also suffer with another fault 5102 on a similar system. I believe this to be a sensor fault? Again, any help on this would be much appreciated.
Thanks in advance.
