Hi guys, Got a classic 07 hydrovane nearly up & running, just need to set up the unloader valve. The original control box was faulty so have used a off shelf star delta. Pressure switch is in & running at 8 bar cut off & 25psi drop cut in. What micro bore fittings do I connect to the unloader? & Am I set up correctly at the back?? I have the star delta timer set at 3s but this could probably be 1s? I can add loads more pictures if required. Not had much luck on line so want a resolution for any one in the future. We have it running clockwise looking at the after/oil cooler end. (Had to swap 2 phases after a bump start check on rotation) TIA Martin Next on agenda is a full oil & filter service The tank is a 270ltr tank only 3 years old & I think 1800hrs on the compressor when we removed the old box. All in cost is £700 for 40cfm so far.
