Cannot get head pressure up after repairing small leak. Unit running -42 box temp at the time. Discharge coming directly out of compressor is only warm. Head pressure 200ibs. This unit is 404. Suction pressure at suction filter 5 and suction line temp at this point is -37. Sight glass 3/4 full but im afraid to keep adding sice head pressure not coming up.
i need more specifics. ambient, condensing unit location and fan staging. HP of unit.
Superheat of coil.
I feel you still need refrigerant. Also make sure that the thermo bank tank is full of either water or glycol/water mix depending on the age of the machine.
The thermobank is full. Ambient temp approx 30 degrees. 3 condeser fans and all cycled off. Condenser outside on roof. Did not check superheat at coil but i do suspect liquid sluggind due to low compressor discharge temp. Also does the suction line temps indicate liquid preset at the suction filter from the readings i gave u.
Based on what I've read I also think you are short on gas. If you have a headmaster, you have lost a lot more gas than you think. The nasty thing simply didn't show up until it got cold out The headmaster was probably trying to stack liquid and stole your load. Now you have to ad enough to not only get the system back up, but you also have to flood the condenser. I like to charge up to a 40% - 50% reciever. If you dont have a level indicator you can use a torch and your finger.
