Hi
Just installed a copeland oqm 110 condensing unit conected to two searle dsr 116 evaps the problem i have is that on switch on the suction held around 3.5 bar and head 21 bar for a short time, then drops off to 1.2 bar and 19 bar. as this happens the sight glass is clear at first then starts to flash followed by the pressure drop. This lasts a minute then goes back to the higher pressure then goes through the whole cycle again and again and again. Not s,o,g.
