Central air conditioning shut down more than 6 hours to open, suggesting that the flow switch did not open, you must turn the water, the pressure on the 0 line, is the system there is air ah! Should the exhaust row clean ah! When the water pressure quickly came down! A pump pressure is also a very fast rise ah! Now I can not figure out why is a short time off all right, shut down for a long time to open it!
Air compressor problems, cooling water can not flow properly, check the pipeline
You should stop the pump after a long time to open the pump, and then open the host. Try it out.
Your unit should be air-cooled chiller, the unit generally in the roof, chilled water pipe has a water switch, is to detect the water in the water pipe is not flowing, if the water flow switch is not closed, the boot will show the flow switch did not open , Check the flow switch "tongue" to see if it is broken.
