OUTDOOR UNIT INSTALLATION

1. Install Drain Port and Drain Hose (for heat-pump

model only)

The condensate drains from the outdoor unit when the

unit operates in heating mode. In order not to disturb

your neighbours and protect the environment, install a

drain port and a drain hose to direct the condensate

water. Just install the drain port and rubber washer on

the chassis of the outdoor unit, then connect a drain

hose to the port as shown in the figure on the right .

2. Install and Fix Outdoor Unit

Fix with bolts and nuts tightly on a flat and strong floor.

If installed on the wall or roof, make sure to fix the supporter well to prevent it from shaking due to

serious vibration or strong wind.

3. Outdoor Unit Piping Connection

• Remove the valve caps from the 2-way and 3-way valve.

• Connect the pipes to the 2-way and 3-way valves separately according to the required torque.

4. Outdoor Unit Cable Connection (see previous page)

Air purging

Air containing moisture remaining in the refrigeration cycle may cause a malfunction on the compressor.

After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant cycle using a

vacuum pump, as shown below.

Note: Because the system pressure is high and also to protect the environment, be sure not to discharge

the refrigerant to the air directly.
