OUTDOOR UNIT INSTALLATION
1. Install Drain Port and Drain Hose
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 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.
