2. Reserve a certain length of drain
hose and power cord for installation
when binding them. When binding to
a certain degree, separate the indoor
power and then separate the drain
hose.
Note:
Ɣ The power cord and control wire
can't be crossed or winding.
Ɣ The drain hose should be bound
at the bottom.
Step nine: hang the indoor unit
1. Put the bound pipes in the wall pipe and then make them pass through the wall
hole.
2. Hang the indoor unit on the wall-mounting frame.
3. Stuff the gap between pipes and wall hole with sealing gum.
4. Fix the wall pipe.
5. Check if the indoor unit is installed firmly and closed to the wall.
