Hi
I'm NOT a refrigeration engineer, but a building manager with a little knowledge.
I have an issue with a M City Multi PURY P250 YMF C.
It keeps cutting out on fault code 1501. My contractor has removed the charge - it was spot on and recharged it. When running - pressures and temperatures seem to be ok. But it trips out about 4 times a week. It has 5 indoor units, 1 indoor runs 24 hrs, the rest run 7am -5pm. Contractor thought that may be the problem, so I had all units going off at 5pm, but it continued cut out on 1501. Normally within 1 hour of start up. Contractor has now been out 6 times! And still hasn't found the problem. I'm loosing faith & my Director is loosing paitence - as his room is affected.
Any ideas?
Also does anyone know if the M Net maintenance tool is still available, as my contractor doesn't have one.
