I'm an electrician working in Portugal. I sometimes install split A/C units. One thing I have difficulty with is gassing up. I have all the needed equipment but don't full understand how to work out how much PSI of gas is needed. Samsung say 120-135 PSI at 35deg ambient outside temp. Is there a way of finding out the temp. and PSI using guage manifold. Cheers. Alan.

The psi is shown on the gauge manifold. The ambient temperature is found using a thermometer.

your gauge manifold has a built in temp and pressure reading on it .it also depends on which ref your using 22 134 516 etc.
