it was currently cascaded with R404A..high stage will remain only the low stage were planning to change. Is't much efficient the price is sure an advantage regarding the R23, only the specifications we wanted to learned? thanks
During the retrofit, add 1.2psi per cu.ft. storage of R290 propane starting from deep vacuum. Charge to same static pressure as R23 and performance charge small additions when cabinet has bottomed out.
