mitsi city multi r407c
Hi guys just wondered if anyone had come across this problem before.
The job has had a history of gas leaks the last which i fixed inside the bc box.
The system was tripple vacced and re charged to mitsis specified wieght and additional pipework charge carried out by mitsi technician in commissioning.
2 weeks later i am called to site.I find the suction pipe iced up from the bc box back to the condenser,When i put all 6 units in heating all units perform well in heating and vice versa in cooling.When i ran for instance 3 units in cooling and 3 in heating it took a while for any to perform.So i turned them all on one by one running them in simultaneous heat/cool until performance dropped but it didnt and the rooms the client wanted cold were cold and the rooms they wanted hot were hot. I have to go to site this week just wondered if anyone has had this problem?
