Installing and connecting the drain hose of the outdoor unit

While heating, ice may accumulate. During the process of defrosting, check if condensation draining is adequate. For adequate draining, do the following:

1. Insert the drain plug into the drain hole on the underside of the outdoor unit.

• To avoid drain plug from contacting the ground, secure gap between the ground and the bottom surface of the outdoor unit.

• In areas with heavy snow fall, piled snow could block the air intake.

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

Purging the connected pipes

The outdoor unit is loaded with sufficient R410A refrigerant. Do not vent R410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975.

You should purge the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as seen in the picture.

• When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first

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
