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.
2. Connect a drain hose to the drain plug.
3. Ensure that condensation draining is adequate.

• 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
fall. In addition, install a snow-proof hood to avoid snow from piling on the
outdoor unit.
• 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
abnormally high. It may cause explosion and injury.
Evacuating the connected pipes
The outdoor unit is loaded with sufficient R22 refrigerant.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.
