Outdoor unit installation
1. Install Drain Port and Drain Hose (for heat-pump model
only)
The condensed water 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 condensed 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 support well to prevent it from
shaking due to serious vibrations 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.
