A few days ago i was with a install team, i was putting in the mains and commisioning. On the test run one daikin unit would not run just sat there without any faults which was strange but at the same time the project manager turned up and decided he was going to diagnose the unit. His first input was we had to re pressure test the unit, when the unit had 200psi standing and had only just been charged, so i disagreed with him so he got on the ladders felt the flare nut and said its leaking because it was a little wet, this could be anything. next he said i think we need to change the fan motor, WHY? GOD ONLY KNOWS. Then he topped it off by saying to me what is the back pressure? how can i tell that when it aint running.Tell me is there any more clowns like this around.
