for the air conditioner. As for the method of wiring, refer to
the circuit diagram posted on the inside of the access door.
2. Comfirm that the cable thickness is as specified in the
power source specification.
3. Check the wires and make sure that they are all tightly
fastened after cable connection.
4. Be sure to install an earth leakage circuit breaker in wet or
moist areas.

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 neighbor 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 to the chassis of the outdoor unit,
then connect a drain hose to the port as the right
figure demonstrates.
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
