Installation Procedure
After selecting the unit installation location, proceed the following steps:
1. Drill a hole in the wall and insert the connecting pipe and wire through a PVC wall-through tube
purchased locally. The wall hole shall be with a outward down slope of at least 1/100. (See
Figure 2)
2. Before drilling check that there is no pipe or reinforcing bar just behind the drilling position.
Drilling shall avoid at positions with electric wire or pipe.
3. Mount the unit on a strong and horizontal building roof. If the base is not firm, it will cause
noise, vibration or pipe broken and refrigerant leakage (see Figure 6).
4. Support the unit firmly.
5. Change the form of the connection pipe, connection
wire and drain pipe so that they can go
through the wall hole easily.
