Re: R-404a running pressures
hi dougie,
i tend to run suction at around 0.7/1.4bar and as long as the hp is below 15bar it should be okay but it really depends on the case.

Re: R-404a running pressures
it depands on the evaporation temperature...
if evaporation temperature is -40 C then suction pressure is around 1 - 3 psig and condensing pressure around 200 psig.
if evaporation temperature is -25 c then sp might be approx. 10-12 psig and condensing presssure might be up to 220-240 psig.
