NOTE
Always close valve A and remove the refrigerant
tank immediately after finishing the refrigerant
charge operation.
The refrigerant charge port of these units have
electric expansion valves that will close
automatically when refrigerant charging operation
has finished. However, the electric expansion
valves will be opened when other operations start
after finishing refrigerant charging operation.
If the refrigerant tank is left with the valve open,
the amount of refrigerant which is properly
charged may be off the point.
