Note:
Open valve stems gently. When opening valve stems, turn the hexagonal wrench until it hits against
the stopper. Do not try to force the valve to open further.
Note:
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. For example, in North America, the standard pipe length is 7.5 m (25 feet).
In other areas, the standard pipe length is 5 m (16 feet). The additional refrigerant to be charged can be
calculated using the formula in the below chart.
SPL = Standard Pipe Length
