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.
