Evening all,
A site we look after has 3 Eaton Williams IPAC close control type units. One of them when switching off has an extrnally equalised TEV which makes a whining/hammering noise. From the sight glass it looks like it passes refrigerant for a few minutes after the compressor stops. Is this something I should be concerned about, will liquid pass into the evaporator and compressor when next starting. It seems to run okay with superheat okay but others say it has frozen up in the summer but I have not witnessed this.
Help very much appreciated.
