Hi, I have just regassed my Samsung fridge/freezer SRL629 and am confused with the following results.
The manual states 65g of R600a is the charge but this seems completely inadequate with the resulting pressures I am getting. I have taken a gamble and doubled the amount of gas but running pressures are still 4 bar discharge and 10hg ie vacuum suction .The standing pressure of the system is not even 0.25 bar. The unit has reached the desired temperatures, however according to the chart I have, the standing pressure at -18oc (freezer temp) should be 0.8 bar and 10oc (current ambient)2.2 bar. So the actual standing pressures should be somewhere in between.
This all says to me, undercharged, but I dare not add any more gas.
Any suggestions would be much appreciated.
