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.

Snow-proof hood

 

 

 

• 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

Estimated

outdoor unit.

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

abnormally high. It may cause explosion and injury.

1.Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2.Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque:

• Excessive torque can be cause of gas leakage.

• Make the electrical connection and leave the system into“stand by mode”. Do not turn on the system!

This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve - EEV -).
