What is the difference between the S10 and the S14 versions of the MG “Blue Star”?
S14 versions have provision to fit a pressure relief valve to the liquid receiver. They also use flexible hose for the pressure lines connecting the high and low pressure switch to the system. (S10 units use copper pipe). S14 models up to and including the MG28 and LG28 are also fitted with a larger capacity liquid receiver. The pressure switch on both S10 and S14 versions is auto reset on the low side, manual reset on the high side.
