A too high pre-filling can cause that liquid refrigerant gets in the compressor and the compres-
sor is damaged.
A too low pre-filling leads to the triggering of the LP alarm and shut-down of the compressor.

•  Continue the filling while the compressor is running.
•  Stop the filling once you see only small bubbles in the sight glass.
•   Note the weight of the refrigerant bottle and determine the quantity of charged refrigerant.

  This is helpful for later inspections and exchange of the refrigerant charge.
