To avoid this incident, install a frame that is higher than estimated snow

fall. In addition, install a snow-proof hood to avoid snow from piling on the

outdoor unit.

You should evacuate the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it aects the compressor.

It may cause reduction of cooling capacity and malfunction. Use Vacuum Pump as seen in the picture.

before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works

with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle

abnormally high. It may cause explosion and injury.
