NOTICE! Liquid pipe that is within 20m(65-5/8feet) doesn’t need to be added with
refrigerant.
First confirm that there is no leakage from the system. When compressor is not working,
charge additional R410a with specific amount to the unit through the filling opening of the liquid
pipe valve of the outdoor unit. If required amount cannot be quickly filled due to pressure increase
of the pipe, then set the unit in cooling startup and fill refrigerant from the low pressure check valve
of the outdoor unit.
