Hi Guys
looking for some advice on a deltec smard 656 air dryer,I normally work on air compresseors but have now got my f-gas to work on the dryers finding them a pain if I'm honest.this unit is showing high dp and temp on the controller fan coming in coil clean etc,has hgbv on I think when adjusting it can hear gas but comp and suction started to frost over and then trip out on low evap temp, have adjusted back ,when gauges on LP was 5bar hp was 19 bar it's r404a and it holds 12kg could it be short on gas sight glass not showing bubbles , not sure what else to look for and can't get any numbers for technical help with this make deltec. Would welcome any advice.
Thanks Sorry that's a deltec smard 656 air dryer
