I Have a 8x8 walk in with a bohn ADT0700F coil unit 1 hp parker valve condensor is a F3AH-A100-CAV-00 (R22) arived on job and the system was low of
charge repaired leak at inlet of TXV and found the drier/sight glass combo under ground (yea it took me a while to find it) as grass had grown over it.lol
Compressor would only pull to 20psig so i ordered a comp and returned and installed it and charged system to 60/280psi with a amp draw of 5.4 data rla 6.7. Its hissing bad at the txv/ coil and has no lquid @ the recever port. I recovered charge and removed recever to check for oil but it was emty and also ran nitrogen through it and the condensor coil/ok. Its got me at this point. I ran high side up to 350 to see what would happen but it was still hissing and running 50 deg sh.
Im returning in the morning and im going to charge with MO 99 so any help will be apped.
