Looking for some help on a conventional cast iron compressor, ie grocery freezer that spewed its charge everywhere on the roof from the condensor. Currently have quote in place for condensor replacement, but customer wants unit running till approved. Added 2 gallons oil and still going out on low oil lockout. Reset then it runs for about 5 minutes and fails. Running about 30 psi on oil pressure from pump w/10 psi on suction. Even pumped down compressor, closed off, contained and checked oil transducer filter. What gives?
