WARNING Electric Shock Warning
Make sure to close the Electrical Components Box lid before turning on the power.
Perform the setting on the PC-board (A1P) of the outside unit and check the LED display after
the power is on via the inspection door which is in the Electrical Components Box lid.
Use an insulated rod to operate the push buttons via the Electrical Components Box’s
inspection door.
There is a risk of electric shock if you touch any live parts, since this operation must be
performed with the power on.
Caution: 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.
Note:
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.
Check the LED display indicate as shown below.
In order to ensure uniform refrigerant distribution, it may take up to around 10 minutes for the
compressor to start up after the unit starts operating. This is not a malfunction.
The refrigerant charge port is connected to the piping inside the unit.
