There is a risk of electric shock if you touch any live parts, since this operation must be
performed with the power on.
Make sure to use protection tools (protective groves and goggles) when charging the
refrigerant.
Due to a danger of liquid hammer, the refrigerant must not be charged over the allowable
maximum amount when charging the refrigerant.
Do not perform the refrigerant charging operation while working on the BS and indoor unit.
When opening the front panel, be cautious of the rotating fan. After the outside unit stops
operating, the fan may continue to rotate for a while.
If operation is performed within 12 minutes after the BS, indoor and outside units are turned on,
H2P will be lit on and the compressor will not operate.
