RTAF
I have a Trane 410t RTAF. I have circuit 1 locked out on the HMI. As it is being repaired and is on a vaccum. I am looking to run circuit 2 but the low evap pressure on circuit 1 inhibits circuit 2 from running. I have been reading document # RTAF-SVX001P-EN and I cannot find why circuit 1 is holding off circuit 2. I have 75psia in the evap of circuit 2.

Hello technicians,
I am encountering an issue with a Hitachi chiller. After replacing the screw compressor and completing the installation, the unit frequently reports a “low suction line temperature” error.
Could you please advise on how to resolve this?j
