Do not fail to turn the power off and charge the refrigerant with outdoor unit in stop mode
before adding the refrigerant following this procedure, otherwise resulting in trouble.
%
Fully open the stop valve on the gas side and oil equalizing valve for multi outdoor
connection, and do not fail to fully close the stop valve on the liquid side. (If the stop valve on
the liquid side is open, the refrigerant cannot be charged.)
