Charging 404A into a new walk-in freezer
I am at my wits end. We bought components to build our own walk-in freezer. Larkin scroll compressor unit, 2.5 hp, 230V 3 phase, LZT025L6C with a Larkin Evaporator: LCE676BB, 2 fan single phase, 230V, liquid line solenoid, piping, 404A etc. to get us down to -20F at least. According to the sales guy we'll need 14 pounds to charge.
Started the unit, inverted the bottle to charge liquid and got it to take 2 pounds on the liquid side with a heat lamp on the compressor and charged another pound on the suction side both through the service valves. The compressor only runs with the contactor pressed in and then shuts off when it gets too hot. Next day took another 3 pounds through the suction side - no heat lamp. Nothing would go into the high side. Today I barely got a 1/2 pound in. I am waiting out a rain storm to get back on the roof and could use some suggestions - what am I doing wrong? It can't take this long to charge.
Thx.
