To avoid this incident, install a frame that is higher than estimated snow
fall. In addition, install a snow-proof hood to stop snow from piling on the
outdoor unit.
The outdoor unit is provided with sucient R-410A refrigerant. Do not vent R-410A into atmosphere: it is a uorinated
greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 2088.
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.
