Outdoor Unit Installation

The condensate drains from the outdoor unit when the unit operates
in heating mode. In order to protect the environment, install a drain
port and a drain hose to direct the condensate water. Just install the
drain port and rubber washer to the chassis of the outdoor unit, then
connect a drain hose to the port as the right figure shown.
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)
