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

draining, do the following:

The outdoor unit is loaded 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) = 1975.

You should purge 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. Refrigerant for air purging is not charged in the outdoor unit.

Use Vacuum Pump as seen in the picture.

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

1. Connect each assembly pipe to the appropriate valve on the outdoor unit

and tighten the are nut.

2. Tighten the are nut rst with your hands, and then with a torque wrench,

applying the following torque:

2. Connect a drain hose to the drain plug.

3. Ensure that condensation draining is adequate.

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.

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.

If using a multi system, install as described in the installation manual supplied with the outdoor unit.
