1.Question:
I bought a car cylinder “as spare item” of your production having capacity of 42 liters. At refueling station I have filled 46 liters !!! How is this possible!?
Good afternoon! The working capacity of the cylinder is 80% of its nominal value, in your case, it is 33.6 l. After reaching this quantity the cut-off valve should operate on the multi-valve and on the fuel-dispenser unit. In winter, due to the reduction of propane vapor pressure, the pressure can be achieved at a slightly larger volume of gas … But filling the cylinder of the 42 l capacity by 46 l of gas is not possible. Apparently, you are faced with unfair autogas filling station.
TIP: contact customer service to adjust the cut-off multi-valve e at the 80% filling of the cylinder from its nominal capacity.
2.Question:
